A guide to coding for cybersecurity

Last updated: May 4, 2021

As a new generation filters into the high-tech workplace many individuals are attracted to the exciting field of cybersecurity. 

The idea of being at the forefront of today’s war against cybercriminals combined with the industry-wide skills shortage makes cybersecurity attractive to some of the best and the brightest. 

Relatively high pay for this sector contributes to its popularity as well. Competition for these cybersecurity positions dictates that newcomers enter equipped with the latest technical skills. Industry veterans must also continue their education to stay relevant in their careers.

An April 2019 research report by Enterprise Strategy Group (ESG) and the Information Systems Security Association (ISSA) indicates that 93% of cybersecurity professionals believe that “Cybersecurity professionals must keep up with their skills or the organizations they work for are at a significant disadvantage against today’s cyber-adversaries.” A skillset deficiency will directly translate into difficulty finding and keeping the most sought-after cybersecurity jobs. 

This same report states that “For the third straight year, a majority (63%) of ISSA members do not think that their employer provides the cybersecurity team with the right level of training.” This is a strong indication that attaining and maintaining relevant cybersecurity skills must be accomplished by the individual on their own time and dime. 

Computer programming is an elementary building block of computer science. Computer science is the foundation of computer security.

Whether preparing for employment as a SOC analyst, network engineer, malware analyst, threat intelligence expert, network security architect, or any other cybersecurity job at least some level of programming ability is essential for success. 

Knowledge of a programming language unlocks the mysteries of how a computer exploit works. In order to discover how an attacker successfully breached a system, a security professional will often need to examine the digital evidence left behind. To make sense of this evidence, an understanding of the language used to create the weapon involved is necessary. 

It is recommended that cybersecurity professionals learn at least one object-oriented programming language. Mastering more than one language is better, but a solid understanding of one language can aid in understanding many other languages. 

There are an estimated 250 popular computer programming languages and as many as 700 in total used around the world. Below are the ten computer programming languages most relevant to cybersecurity professionals. 

These are the languages commonly used by cybercriminals, therefore, a good understanding of them will provide a significant advantage to security professionals that are proficient in one or more of these languages over those that are not. This list and accompanying descriptions should be used by cybersecurity professionals to determine if their programming skills are up to date and to lay out a course for further career education. 

The popularity of a programming language, specifically among bad actors, is an important barometer of whether or not a security professional should invest time and money in learning that language.

Nine of the ten programming languages that have been identified in this guide as being particularly useful for cybersecurity personnel are listed in the TIOBE Index for December 2019. The TIOBE Programming Community index is an indicator of the popularity of programming languages. Compared to each other, these languages are addressed in order of popularity below.

Note that this guide discusses C and C++ together while the TIOBE popularity index addressed them separately. Also, the single outlier that is not included in the index’s top 20 list of popular languages is Lisp. 

Understanding Java

As the most popular programing language for programmers generally, Java has a lot to offer cybersecurity coders as well. If a coder is focused more on computer or mobile device software development over web applications, they are likely to improve their employability by acquiring and maintaining knowledge of the Java programming language. Java is a general-purpose language that is designed to require a reduced number of implementation dependencies. The idea is to let application developers write once, run anywhere (WORA). Compiled Java code can run on all platforms that support Java without the need for recompilation. It is one of the most useful programming languages in use today and is structured similar to C/C++.

Java is an important component of the Android mobile operating system even though there are historic and current legal struggles between Oracle (self-described steward of Java technology) and Google (main contributor and commercial marketer of Android). 

Java is important for security practitioners because it is so widely used. A variety of industry sources estimate that over 95 percent of enterprise desktops run Java, and of all computers in the U.S., 88 percent run Java.

The similarities between C/C++ and Java make it a natural proficiency to add for those already knowledgeable in the former. A C/C++ programmer looking to spruce up their cybersecurity resume would do well to learn Java as well. 


The C programming language, originally developed at Bell Labs by Dennis Ritchie between 1972 and 1973, is arguably one of the most important programming languages for cybersecurity professionals to master. C++ was created by Bjarne Stroustrup as an extension of the C programming language. Sometimes called “C with Classes” it is essentially an upgrade to the C programming language. Many millions, or even billions of devices around the world, including those running Windows, Mac, or Linux operating systems, operate using the C or C++ programming languages. Since C++ is an extension of C they are sometimes referred to as a single language, namely C/C++.

The historical popularity of these languages fuels the continuing demand for security specialists with a deep knowledge of them. It is commonly accepted that most malware is written in the C/C++ programming languages and they are, therefore, an essential skill for cybersecurity professionals to possess.

 Because C/C++ are lower-level languages than languages like Python or Java, they are, in some ways, much more powerful, albeit more difficult to master. Using low-level languages gives direct access to low-level infrastructures like RAM and system processes. This low-level access is what makes C/C++ attractive to cybercriminals and particularly dangerous in their hands. 

Note that C/C++ are not typically used by novice adversaries, commonly referred to as script kiddies. These languages can take years to master. An understanding of C/C++ coupled with knowledge of assembly language gives hackers extensive perspicacity into programs and their memory management.

C/C++ are also important for reading and understanding open source code, which often supports low-level system programs that are critical components of operating systems. Many black hats work with and depend on open source code for their activities.

Learning Python

Growing in popularity among security professionals as well as hackers is the high-level scripting language Python. It can be used for developing desktop GUI applications, websites, and web applications. Aficionados of this language insist the language is, by virtue of its massive community, the best choice for novice bad actors to use. The rationale is that easy access to online help from the community of users is destined to yield methods for a wide range of manipulation that can be used for treacherous purposes. 

Since Python is a high-level language it is not comparable with C/C++ for power, detail, and exposure to hardware. Conversely, the readability of the language can provide a reasonable sense of the intended purpose for code written in Python. This makes an understanding of this language useful for cybersecurity pros. 

With the benefit of a growing number of libraries, security teams can employ Python to perform malware analysis, create intrusion detection systems, and send TCP packets to machines without third-party tools. This means that they can build programs and automate work in an efficient manner.

What is JavaScript?

Not to be confused with Java, JavaScript (JS) is a high-level, just-in-time compiled, object-oriented programming language. JavaScript is one of the main technologies of the internet. The large majority of websites employ it, and most web browsers have a dedicated JavaScript engine for its execution. JS provides websites with their ability to use animation and to be interactive.

JavaScript can be used by bad actors to collect user input and browser data. Hackers can use JS to track data entered into a web form or analyze browsing habits through cookies. It can be used to replicate legitimate websites to be used with cross-site scripting redirecting users in a phishing campaign.

These security exploits are becoming more common and more sophisticated. It is becoming more difficult for users to detect the subtle differences between the legitimate site and the imposter. 

An understanding of JavaScript, its uses – both legitimate and nefarious – will make an individual more employable in the field of cybersecurity. An individual should look to acquire and maintain knowledge about JavaScript if their area of focus is on websites or web applications.

Understanding PHP

PHP is a widely used open-source general-purpose scripting server-side language. Many large-scale websites use server-side code to dynamically display information. When needed, data is pulled from a database stored on a server and sent to the client to be displayed.

Perhaps the most notable benefit of server-side code is that it allows for user-specific website content for individual users. Dynamic websites highlight content that is more relevant based on user preferences and habits. It can also make websites easier to use by storing personal preferences and information, for example, reusing stored credit card details to streamline subsequent payments.

PHP powers a huge number of websites including the 75+ million WordPress websites. Some estimate that 80 percent of the web is powered by PHP, including social networks like Facebook, although theirs is a custom version. PHP has risen to popularity because its features make it easy to update a website. PHP’s ease of use features also make it more vulnerable to attacks from the outside. As a result, PHP is a particularly important programming language to learn for those wishing to work in cybersecurity.

One of the most common hacking attempts on PHP-based sites is DDoS (Denial of Service) attacks designed to cripple a website.

Criminals can use PHP to delete all the data on a poorly constructed site. Knowing how to identify and solve these vulnerabilities in PHP code can save an organization’s entire database.

More than one cybersecurity blogger has stated that if a cybersecurity professional can learn only one language and there are other significant determination factors, PHP is likely the best choice.

Learning SQL

Structured Query Language (SQL) is used to manage databases and retrieve the data that has been stored in them. A SQL query is a request for some action to be performed on a database. SQL injection (SQLi) is a popular type of security exploit in which the attacker adds SQL code to a web form input box in order to gain unauthorized access to resources or make changes to sensitive data. When executed correctly, an SQLi can expose sensitive intellectual property, personal information of customers, administrative credentials, or private business details.

SQL injection attacks can be used to target any application that uses a SQL database, with websites being the most common victim. Common SQL databases include MySQL, Oracle and SQL Server. With SQL injection, cybercriminals are able to make queries and get access to almost any data they want. This can result in the loss of passwords, bank account information, social security numbers, addresses, and much more.

An understanding of SQL, it’s legitimate uses, and how SQL injection is used to manipulate websites is critical for cybersecurity professionals. SQLi is one of the top threats to web application security. Security defenders, as well as pen-testers, will greatly benefit from the mastery of SQL. 

Apple’s Swift

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, iPadOS, macOS, watchOS, tvOS, Linux, and z/OS. It was introduced at Apple’s 2014 Worldwide Developers Conference and was officially released in September 2019.

Swift is an interactive programming language that combines modern language thinking with wisdom from the wider Apple engineering culture and the diverse contributions from its open-source community.

Due to its increasing popularity among programmers, both legitimate and illegitimate, combined with the fact that mobile devices represent the single fastest-growing attack surface, Swift programming language is a good candidate for any cybersecurity practitioner to learn. This is especially true for those focused on development and security for the various Apple products and operating systems. 

Learning Ruby

Ruby is an interpreted, high-level, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro “Matz” Matsumoto in Japan. The syntax of Ruby is broadly similar to that of Perl and Python. It was written in C language. Frequent users laud its ease of use and innate ability to maintain large code projects. Reports indicate that Ruby is used widely for websites such as Airbnb, Hulu, Kickstarter, and Github.

Ruby is attractive to beginning programmers and is therefore attractive to new hackers as well.

It is marketed as “fun to work with.” It is a very high-level language and handles most of the complex details of the machine allowing programs to be built quickly from scratch with less code. 

This easy to use and easy to learn programming language could possibly be a great additional language to learn in an effort to enhance a cybersecurity resume. 

Understanding Perl

Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more. It is an interpreted language, which means that code can be run as-is, without a compilation stage that creates a non-portable executable program. 

Perl is generally considered an easy language to learn. While it is not nearly as readable as Python, it borrows syntax from various programming languages like C. It is, therefore, popular with programmers proficient in those languages.

While it is an older language and is often positioned as a rival to Python, Perl is particularly useful for security practitioners because it was used in a wide range of legacy computer systems. These same systems are often the target of bad actors. 

Learning Lisp

Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today. Only Fortran is older, by one year. Due to the difficulty programmers often have in mastering it, Lisp is not a popular language. It is, however, extremely powerful. 

Lisp would not ordinarily be recommended as a candidate for a new programmer’s first language but is a good choice for a veteran programmer looking to add a powerful tool to their arsenal.

Complex attack tools developed and deployed by sophisticated adversaries are known to be created with legacy tools such as Lisp. The ability to wield the power of this language can provide the cyber-defender the means required for defense-in-depth.

Concluding coding for cybersecurity

Cybersecurity is not simply knowing about potential vulnerabilities and how to correct them. It is much more than that. A successful cybersecurity practitioner will need to learn to think like a hacker. Intimate knowledge of the hacker’s programming tools will enable a defender to anticipate the overall strategy and the employed tactics of the attacker. The ability to quickly identify the adversary’s methods and thereby predict his goal will enable security to defend more successfully. 

For aspiring penetration testers, learning a programming language will improve their understanding of where flaws might exist in code and how to exploit them. Without a sound knowledge of programming principles, it would be impossible to identify faulty code or conduct a meaningful penetration test.

For incident responder hopefuls, the ability to investigate breaches, analyze malware, and reverse engineer attack tools will help them surface to the top of their field. 

A risk specialist will benefit from learning code by an increased ability to understand and apply mitigation techniques and solve complicated software related problems. 

With so many programming languages to choose from how can a cybersecurity professional, or someone aspiring to a career in cybersecurity, make a reasonable decision about what language(s) to learn?

Hopefully, this guide will illuminate the available options and order them into a useable perspective. The two most salient considerations for making this choice are what language will enhance the ability to create strong defenses and, second, what tools are the adversaries using to create their weapons. 

Which language will allow the security professional to create strong defenses will, in large part, be determined or influenced by the standards established by their employer. Security programming is done in a team environment. The defensive tools needed in today’s threat laden cyber landscape are both sophisticated and flexible. While custom solutions are sometimes developed internally for large enterprises, most are created by vendors that supply security tools to the industry at large. 

Learning which language will best equip a security professional to recognize, reverse engineer, or protect against cyber weapons deployed against their specific system is accomplished, in large part, by collaboration with their peers.

Security teams that are defending similar systems, websites, or applications can be an invaluable resource in anticipating the tools to be used in a future attack. An understanding of the language used to deploy that attack is a good indication of the language that would be most useful to the defender. 

Each specific role under the larger umbrella of cybersecurity will likely profit from the knowledge of a different programming language. For example, a software malware analyst may need to be proficient in C in order to analyze viral code and assess what it does without running it. A network security architect may find more need for the power of Lisp in defense of the enterprise’s networks. A website security analyst might benefit from a knowledge of PHP. 

If hoping to move up within their existing employer’s organization, the best choice for learning or adding a programming language should be self-evident. The organization’s security leaders will clearly understand what language will be most useful. Alternatively, if looking for a career change outside of their existing employer, a search of a tech job board will likely yield a clear understanding of what specific programming language is required for the desired cybersecurity position.

Cyber security — it’s more in vogue today than it’s ever been. Between 2020’s highly consequential data breach and huge cyber and IT skill demand projections for the next decade, cyber security is a bigger topic now than it’s ever been. Ten years ago, many of us wouldn’t have ever even heard the phrase, let alone know what it meant. 

Unsurprisingly, with so many headlines about cyber security, there’s also growing interest in joining the industry. So, what are the best programming languages for cyber security? Let’s find out.A web of cyber security languages

Why learning programming is important for cyber security

Simply put, it makes you better at your job. Understanding programming helps cyber security experts examine software and discover security vulnerabilities, detect malicious codes, and execute tasks that involve analytical skills in cyber security.

The choice of which programming language to learn, however, isn’t so simply put.

The language to learn depends on your concentration, which could be in computer forensics, security for web applications, information security, malware analysis, or application security. Though the importance of any given language varies by role, programming experience offers a higher competitive edge for cyber security experts over others.

And although not all cyber security positions require a programming background, it’s an important skill to have for mid-level and upper-level cyber positions. A strong understanding of programming languages helps cyber security experts stay on top of cyber criminals, and having a good grasp of the architecture of a system means that it is easier to defend it.

Fortunately, the beginning of a cyber security career is the ideal time to build your programming knowledge. This way, when you hit the job market, you’ll know the essential components of programming and will be able to read code and comprehend its functions. 

What programming language should I learn for cyber security?

There are about 250 prominent computer programming languages used today, with as many as 700 used around the world. In cyber, that number shrinks to around 10-15. Here are the twelve best programming languages to learn for cyber security, so you can set your sights toward starting a new cyber career.


Pythons popularity by year according to pull request percentages on GitHub. Python is trending even, at around 16% of all GitHub pulls.

For several years now, Python has been a dominant language in cyber security. It is a server-side scripting language, so the resulting script doesn’t need compiling by coders. It’s a general-purpose language that is used in many — if not most — cyber security situation.

With Python, you’re able to automate tasks and perform malware analysis. Plus an extensive third-party library of scripts is readily accessible, meaning help is right around the corner. Code readability, clear and easy syntax, and a vast number of libraries are some of the aspects that make it popular.

For cyber security experts, Python is a valuable programming language since it can be used in detecting malware, penetration testing, scanning, and analyzing cyber threats. If you understand Python, being a SOC support pro makes a whole lot of sense. 

You need to build tools and scripts in this role to protect web pages from security threats. To examine the root of the issues, you can also employ data, logs, and artifacts.

As a side note: The chart above shows the relative popularity based on how many GitHub pulls are made per year for that language. This chart and all the charts below are based on data from GitHut 2.0, created by littleark.


Go's popularity by year according to pull request percentages on GitHub. Go's is trending upward, and has around 9% of all GitHub pulls.

  • Most malware aims to get into target systems undiscovered, making Golang perfect for it.
  • With Golang, a single source code can be constructed for all major operating systems.
  • The size of malware coded in GoLang is large. This helps them to penetrate systems undiscovered since large files cannot be scanned by a lot of popular antivirus software.
  • This language also has vast libraries that make the malware creation process very smooth.

Go has become quite popular as a language for security professionals. It’s a perfect option for cyber programmers for its use in server and cloud services, flexibility and ease, and data analysis capabilities.


JavaScript popularity by year according to pull request percentages on GitHub. JavaScript is trending slightly downward, though is the most popular language on GitHub at around 19.5% of pulls.

The most common programming language is JavaScript, a universal language used by 95 percent of internet sites.

It’s one of the finest programming languages for cyber security you can master. 

  • JavaScript is for you if you want to capture cookies, exploit event handlers, and carry out cross-site scripting. 
  • NodeJS, ReactJS, jQuery — these are all JavaScript libraries.
  • This also implies that, due to the widespread use of the language, applications and systems using it are prominent targets.

JavaScript lets programmers use any code while users visit a website, strengthening that site’s functionality. On the other hand, it may produce malicious functionality hidden from the visitor. If the web site is compromised, malicious codes may be used to run a program.

If you’re a JavaScript expert, you can ensure that any site is safe enough to reduce or even remove Cross-Site Scripting (XSS) attacks.

JavaScript’s also used by front-end developers, full-stack developers, back-end developers, and more. It’s the most versatile language there is, and the most popular language there is.


C and C++'s popularity by year according to pull request percentages on GitHub. C and C++ are trending even, and have around 10% of all GitHub pulls.

  • Applying C language in reverse engineering facilitates the development of antivirus programs because cyber security teams can disassemble a malware to examine its design, spread, and consequences.
  • The C programming language is also essential for developers who QA code integrity.
  • Cyber enemies may also use the language to identify exploitable weaknesses in the network before an attack is launched.

Being a low-level programming language with simple syntax, someone can master it with a few months of training. Programmers take further steps to make sure that their code lacks bugs when writing the program. Hackers can use it to find vulnerabilities, though.

Lint is a code analysis tool intended for programs that are written in C. Different versions have emerged since its inception. Both cyber security experts and hackers may use Lint to identify programming errors, and find bugs that risk computer network security.


C++ was adapted from the C coding language, but has several distinct features.

  • In contrast to C, C++ supports objects and classes.
  • C++ is faster and performs better than the C language. 
  • Despite being useful, less than 0.1% of all websites use it.
  • A C++ developer develops desktop and mobile apps, whereas coding specialists identify and eliminate any vulnerability and bugs.

Cyber security experts benefit learning C++ because they can detect vulnerabilities and security weaknesses easily. A scanning tool like Flawfinder that scans C++ lets cyber experts easily recognize security flaws in code. These tools describe existing vulnerabilities, their severity, and their effects on an application by using an integrated database that includes the language function’s possible risks.


SQL (Structured Query Language) is a domain-specific programming language. It highly popular and is used to parse data in large databases. With businesses becoming more data-driven, SQL is the most demanded database management programming language.

  • Most websites use SQL for their data management activities like Relational Database Management System (RDBS).
  • It deals with numerous database systems.
  • Consequently, it is also recognized as the most straightforward language for handling a database.

Database Administrators, programmers, and end-users create SQL queries for the retrieval, insertion, modification, and removal of data stored in database tables. Attackers often use this language to steal confidential data, compromise data stores, and execute a variety of web-based attacks.

You’ll need to have at least a basic knowledge of SQL if you want to comprehend the activity of the attacker and avoid SQL injection as well as other database-related attacks.


  • An assembly language is any low-level language that helps analyze and understand how malware works.
  • Understanding assembly is relatively straightforward, especially if you already know a high-programming language.

In 2003, Slammer, a malware based on assembly, caused disorder and slowed web traffic by forcing service negligence on many, many proprietors. There was a protective overflow bug on Microsoft’s SQL server that the program exploited. This incident was not a sudden one — several months before a patch was released — but several enterprises didn’t implement it, opening the door for the bug to propagate.

Assembly is an essential programming language as cyber security experts might use it to interpret malware and understand their modes of attack. Cyber security professionals defend against traditional and contemporary malware continuously, and so it’s essential to understand how malware functions.


PowerShell's popularity by year. PowerShell is trending downward. It was used in ~.2% of all GitHub pull requests in 2020.

PowerShell is a more versatile command-line interface that blends the old Command Prompt (CMD) features with an advanced scripting environment that can be used to get access to the inner core of a machine, including Windows APIs access.

  • PowerShell is a valuable tool to automate repetitive tasks for administrators, but sadly, its capabilities have also been exploited by malicious actors.
  • No longer having to rely on typical malware, Hackers can manipulate PowerShell to find sensitive domain information and load harmful executables (also known as fileless malware).
  • Because PowerShell is installed on all machines from Windows 7 to Windows Server 2019 by default, it’s a preferred tool for many attackers.


Ruby's popularity by year according to pull request percentages on GitHub. Ruby is trending downward, and has around 6% of all GitHub pulls.

Ruby is a general-purpose high-level language created and developed by Yukihiro Matsumoto in Japan. Since then, it’s become one of the most popular programming languages in the world.

  • Ruby’s syntax is essentially identical to Perl and Python. 
  • It was written in C.
  • Its ease of use and inherent ability to manage massive code projects make it popular among coders.
  • Ruby has been widely used for sites including Airbnb, Hulu, Kickstarter, and Github.
  • Ruby manages much of a machine’s complex information, making programs easier to develop and with less code.


Java's popularity by year according to pull request percentages on GitHub. Java is trending upward, and has around 12% of all GitHub pulls.

Java is one of the first languages to be used in the design of many major operating systems, like Solaris, Linux, macOS, and Microsoft Windows. Since it drives both modern and legacy web servers, it is extensively used in all industries.

In information security, the Java language has many applications. 

  • Cyber adversaries, for instance, use it to reverse-engineer proprietary software applications to discover and exploit security vulnerabilities.
  • Penetration testers often use Java to organize high-scaling servers they use in payload delivery.
  • Pen testing is one of the essential tasks of a cyber security specialist, and understanding Java makes it easier.
  • Experienced ethical hackers use Java programming to build and develop sophisticated, ethical programs.
  • Java is highly dynamic compared to languages like C++, making it popular among cyber experts.
  • Using Java to develop vulnerability testing programs lets ethical hackers deploy it on multiple platforms.


PHP's popularity by year according to pull request percentages on GitHub. PHP is trending downward, and has around 6% of all GitHub pulls.

PHP is a server-side programming language used to build websites. PHP is perhaps the most powerful server-side language there is, used in 80 percent of the web’s top 10 million domains. For this reason alone, it’s obvious that understanding PHP will help you protect against attackers.

  • RIPS is a standard tool for PHP applications that performs automated security analysis.
  • In an application, RIPS examines data flow from input parameters to critical operations.
  • You could use RIPS if you’re a PHP developer working with security vulnerabilities.
  • As a PHP security-focused developer, you can write server-side web application logic.
  • You can handle back-end resources and data sharing between servers and their consumers using PHP  
  • You can also use your PHP knowledge to eliminate any vulnerabilities in your code.

It’s also worth noting that PHP is used by businesses as a language on the server-side that works with HTML, helping websites work properly. To make website updates easier, web designers use PHP to connect databases with web pages.

Shell scripting

Shell scripting's popularity by year. Its trend is level. In 2020, shell scripting accounted for ~2% of all pull requests on GitHub.

Shell scripting incorporates several of the same commands that you may already use in your operating system’s terminal sessions and lets developers create automated scripts for various routine activities.

Do you need to provision accounts quickly and facilitate sufficient access? Do you want to automate a system configuration security lockdown quickly? This is where shell scripting comes into play.

You’ll want to master some Linux script languages like Bash if you’re using  Linux or macOS. If you’re a Windows pro, immerse yourself in PowerShell.

What’s the first cyber security language I should learn?

We recommend starting with Python. The syntax is straightforward and there are countless libraries that make your coding life much easier.

In cyber security, Python is used to conduct many cyber security tasks like scanning and analyzing malware. Python is a helpful step towards more sophisticated programming languages, too. It offers a high level of web readability and is used by tech’s largest companies, including Google, Reddit, and NASA. Once you have Python down-pat, you can move on to high-level programming languages.

What are the best ways to learn these cyber languages?

Like with any type of coding language, there are lots of ways to get started learning. It really all depends on how much time and money you’d like to commit to. If you want to learn casually or dabble in coding before committing, we suggest starting with a free introductory course.

Is Java relevant to Information Security?

Ask QuestionAsked 7 years, 4 months agoActive 5 years, 11 months agoViewed 6k times112

I’m currently studying Computer Science, where we’re teached Java programming. I want to get into the IT-security field, but it seems to me that Ruby and Python are more relevant for that, so I have a hard time motivating myself to learn Java.

But do Java have a place in modern IT-Security compared to say, Ruby or Python?javaShareImprove this questionFollowasked Jan 19 ’14 at 14:42user3753411311 silver badge44 bronze badges

  • 7Java has a place in security in all the wrong ways. – Steve Jan 19 ’14 at 18:23
  • I think you should go into the “jack of all trades” path here. But just having some grasp of “how to make a GUI in Visual Basic to trace the criminal’s IP” (lol) doesn’t cut it 😛 So in other words, there’s a long road ahead of you. – Camilo Martin Jan 20 ’14 at 0:49
  • 1If it’s a language that gets used for real-world applications, then it’s relevant to security. Java certainly fits the bill as one of the most widely-used languages out there. – Mike Ounsworth Jul 7 ’15 at 18:22

Programming is relevant to IT-Security; it may be subtitled as “yeah, I kinda grasp the concepts of what I am blabbing about”. You cannot be a decent practitioner of IT security if you cannot imagine what occurs in a computer beyond something like “then magic occurs”. This necessarily implies some basic skills at development.

The exact programming language does not matter much. In fact, if the programming language matters to you, then you don’t know enough programming yet. If you want to “get into the IT-security field” then you must reach the point where your question feels ridiculous, as in “how could I have been such a twerp to ask such a silly question ?”. Meanwhile, go learn how to do basic programming in at least two or three different languages (Java may be one of them); this is the path to enlightenment.ShareImprove this answerFollowanswered Jan 19 ’14 at 14:57Tom Leek165k2626 gold badges329329 silver badges464464 bronze badges

  • Could you clarify on “if the programming language matters to you, then you don’t know enough programming yet”? – Heisenberg Jan 20 ’14 at 2:20
  • 4@Anh: If you know one language, or are trying to only learn one language, you’re naturally going to tend to look at every problem from that language’s POV, and possibly try to shove it into that language’s little box. If you’re solely learning Java, for example, the concept of a buffer overrun might be too abstract to even make sense to you. You need to know something about at least a couple of different languages, including C and/or an assembly language, so you can step back and look at things from a more language-agnostic, more computer-centric POV. – cHao Jan 20 ’14 at 3:34 
  • 2Not just that, but the fact that most security flaw types are agnostic to the underlying programming language. You could equally have buffer overflows in C, C++, and Delphi. You might have poor password storage in any application, regardless of the languages and technologies involved. Even SQL injection is not limited to a particular dialect of SQL. – Polynomial Jan 20 ’14 at 12:09

If you want to get into technical IT Security you should get a solid basis in all different subjects, programing, networking and system administration. Motivation to learn, often rather boring and complex subjects, is important. Only by understanding how something works, you can find out if it works securely or not.

Python and Ruby are as relevant as Java,C,LISP or even COBOL. Every single programing language is just a tool used to achieve your goal: perform a security assessment in an automated way. Python and Ruby are often used to write scripts, but this is not only relevant to IT Security, but just in general for the IT community.

Java is used less than Python and Ruby to create scripts, but it’s definetely relevant to IT Security when it comes to, for instance, client side exploitation. You must also remember that these days a lot of application are being written in Java. Part of IT Security is to assess existing applications by looking at its source code. Having a solid basis in Java is imperative if you want to assess Java applications.ShareImprove this answerFollowanswered Jan 19 ’14 at 14:55Lucas Kauffman53.6k1717 gold badges107107 silver badges190190 bronze badgesAdd a comment4

Java is in fact extremely relevant to information security because the Java Browser Plugin is one of the most prominent ways of malware distribution. See e.g. this recent article:

The Cisco 2014 Annual Security Report found that Java represented 91 percent of all Indicators of Compromise (IOCs) in 2013.

If you plan to work seriously in security, you’re most likely going to be faced with a lot of malicious or vulnerable Java. This makes a basic knowledge of Java important, but more important yet is a solid understanding of programming and computing principles: you must understand what actually happens in a computer on a systems-level. You should learn several programming languages and become a competent programmer — it goes hand-in-hand with working in IT security.

Moreover, to aid your understanding, you should not only use high-level languages like Java or Ruby or Python, but you should learn languages closer to the machine level (at least C, understanding assembler would also be good if you want to fight malware) if you really want to do security.ShareImprove this answerFollowanswered Jan 19 ’14 at 20:47Newb17377 bronze badgesAdd a comment1

Does Java have a place? Oh Yes!

  1. As Newb answered, Java Browser Plugin was one of the biggest security holes in the past few years. Since I was a Java developer, I was able to help guide my organization, which still uses Java applets, through the pains of locking this down.
  2. Many, many web applications are written in Java web frameworks such as JSP, Struts, Spring, Java Server Faces. Many of these apps were written before everyone understood web app security so many organizations have critical and insecure Java apps. The security field needs people like you to secure these applications. As a Java developer, I have been able to find holes in Java applications that someone without Java experience would probably not find.
  3. Many security tools are written in Java. I’m thinking of Burp Suite, ZAP Proxy, Dirbuster and SOAPUI.
  4. Android is the most common mobile platform and the most insecure. Android apps are written primarily in Java. There is a huge need out there for people who understand Android and its application ecosystem security.
  5. This statement might seem funny after the long plugin nightmare, but Java was designed to help developers avoid many of the security mistakes possible in languages that came before. I’m thinking of: Array bounds checkingstructured memory access, and type safety. C# and other languages adopted these features. Understanding the language and studying these security features will have broad application.

FREELANCINGGIG.COM FREE EMAIL SIGNATURE GENERATOR GLOSSARY SHOP BECOME A SPONSOR STARTUP RESOURCES PYTHON VS JAVA FOR CYBER SECURITY: WHICH IS BETTER KITTY GUPTA — OCTOBER 23, 2017 Cyber security is the body of technologies, and it is the process and practice designed to guard networks, data, computers, and program from unauthorised access, attack and damage. Cyber security is not simple as the attack happens every single day and attackers get inventive. The security of computing context includes physical security and cyber security. You can hire freelancers who know cyber security concept. It is the important concept in the military, corporate, government, medical organisation, and financial which collect process and store extraordinary data on computers and other devices. The cyber security protects data integrity of computing assets which is related to the organisation. The main purpose of cyber security is that to protect those assets against all threat in complete life cycle of cyber attack. The strategies of cyber security include risk management, incident management, and risk management. The most difficult element of cyber security is that frequently occurs security risks. The traditional cyber security concept only concentrates on most known resources and most important components and defends the system against the biggest known threats and does not defend some less dangerous risk. But the latest cyber security advisory organisation resolves this all issues and promoting the adaptive and proactive approach. Python vs. Java for Cyber Security: Python is the excellent programming language because it creates for rapid application developments. It is also helpful for those programmers who don’t have knowledge of programming and want to create an application in the little amount of time. The professionals of cyber quickly create the prototype, deploy and test application. Python is cross-platform and has the versatility of running as a script. This language has the mixed code environments which easily combine different programming languages. You can also embed code of Java in Python easily. The experts of cyber security codes for different scenarios and they need more functionality, speeds, libraries and code reusability. This language supports all mentioned scenario and allows testers, and system administrators to develop customised tools. The testers, hackers, and other security experts required the language library which provides the most powerful features to create programs. This programming language has inbuilt modules which easily help web activities such as parsing HTTP and XML building clients. The clean syntax of the programming language to create code is simple and extends that code easily. In the world of cyber security, the versatility of Pythons is most advantageous. It is an excellent language for creating the complex, compiled applications and its scalability make it the default choice for diverse coding needs within an organisation. Much cyber security specialists offer to build the existing code. The Python programming language has an ability to used the existing code so that it saves time, preserves existing functionality and provide great security role. If you are developing the applications in Java programming language, then new release of Java provides excellent cyber security functionality. The new released of Java removes unnecessary functionality and adds the excellent cyber security. The new released is removes the weaker algorithm and restricting lower sized keys. It has excellent code environment which is easy combines with the different programming language and same as python programming language you can embed the code of Python in Java programming language easily. This language has inbuilt security API and that API uses programming approaches such as context and dependency injection for simplifying the security API across all platforms. The application portability is also significantly improved through self-contained security. Java programming language has an excellent libraries function that allows the developer to create the application easily. You can hire freelancers who have knowledge of Java programming language regarding cyber security concept. Java programming language used the networked environments. The memory model of Java defends against the malicious code. The Java programming language has more effective features than PHP programming language. Automatic garbage collection is a feature which prevents memory leaks. This language has detailed compile-time checking so you can find viruses quickly. It is repeated at runtimes for flexibility and to check consistency. In Java programming language you can keep your data exchange secure because this language used Secure Socket Layer (SSL) protocol. The developed connection will be routed through some intermediary servers to get the main server, and this certificate makes your connection secure. You can find freelance jobs online in cyber security sectors. Summary: This article gives information regarding cyber security and role of cyber security in Java and Python. Cyber security practice designed to protect networks, data, computers, and program from unauthorised access, attack and damage. The cyber security plays an excellent role in both languages because of its inbuilt library and features. AuthorRecent Posts Kitty Gupta Kitty Gupta is FreelancingGig’s Content & Community Manager.

In this article, I describe major programming languages according to its popularity, usage, demand and ease of learning. 

There is market demand and a potential salary range for each language. These are linked to specific personal goals and prior programming experience.

What Questions Should You Ask Yourself Before Diving in?

  • What kind of projects do you want to work on? If career flexibility is a priority, then learning Python or C++ will allow you to work with different types of programming. If your passion is web development, learning JavaScript or PHP is a smart choice.
  • How much experience do you have? You won’t want to switch to an advanced programming language, such as Rust, if you don’t have previous programming experience. If you’re new to a language, you’ll want to start at a higher level and be intuitive.
  • What are your career goals? Do you want to become a freelancer, working for an existing company or work with a startup? Are you trying to be better in your current role?

If you plan to get a job in a large technology company, learn the programming languages they use, e.g., NASA, Google and Facebook use Python.

Many programming languages have similar syntax and qualities—so if you learn one of them, it will be easier for others. The more languages you know, the more flexibility you have in your career and development projects.

In the list below, we will look at the best and most popular programming languages for many of the most common uses, including web development, mobile development, game development and more.

Top Five Programming Languages to Start Your Career


It is probably the best programming language if you are looking for a common language that will be useful in various situations. As for choosing a programming language to learn, there are many resources for people who are thinking about learning Java. Java was released in 1995, which makes it one of the oldest programming languages. It is used on a wide range of platforms and operating systems, including Microsoft Windows, macOS, Linux and Solaris. 

That means there will always be jobs for Java developers, making it (perhaps) the best programming language to learn.

Research shows that Java developers can expect to earn between $80,000 and $130,000 per year. If you are thinking about learning your first programming language, think about taking an online course, for example, CodeGym. This course, which contains 40 levels of game-play classes, will teach you all the basics you need to know to start programming in Java. It’s easy to follow—even if you don’t have programming experience—and it is worth checking out.

It is also best used for back-end web development, mobile development and desktop applications.


This programming language works on several platforms. Therefore, it is ideal for websites that will be accessed through various devices and browsers. It is suitable for anyone who designs websites with effects, interactive features, animations and pop-ups—standard features on virtually any brand website these days. If you want to work in a creative environment and add more experience to the user, this is a coding language to learn.

JavaScript is the number one language on the web. The growth of frameworks such as jQuery, Angular and React JS has made JavaScript even more popular.

If you just can’t stay away from the internet, it’s better to learn JavaScript sooner than later. I consider this JavaScript Masterclass an excellent place to start. For cheaper alternatives see this list of free JavaScript courses.

It is also best used for front-end and back-end web development

Learning PHP

PHP—another old language, first appeared on the stage of programming around the same time as Java in 1995. It is a general-purpose language widely used for web development from the early days of the web.

Unlike other languages, which can be quite tricky to use with HTML, PHP can be built directly into the HTML code block. Start and finish instructions are used to enter and exit PHP, making it very easy to use. Although PHP is not as popular as Python or Java, it can be a suitable language to learn because of its simplicity. It is convenient for beginners and you can write your first scripts just a few hours after you start your PHP course.

Again, the popularity and wide use of PHP means that work opportunities are relatively easy to find. An average PHP developer can expect to earn around $80,000 per year. However, there is potential to make much more as a freelancer.

Take an advanced PHP course, which will teach you everything you need to know to find your first job as a programmer. It doesn’t matter if you’re studying your first language, or if you’re an experienced developer looking for the best programming language to add to your resume—PHP is a great choice!

It is best used for back-end web development.

Python is a useful step toward more advanced forms of programming languages. Python provides a high degree of website readability and is used by companies such as Reddit, Google and even NASA.

It is seen as entry-level programming that does not require too much prior knowledge. It may be ideal for relatively new professionals to help small businesses that want to expand their presence on the internet without having to resort to advanced professionals. Python is a relatively simple programming language that is very easy to pick up if you already have programming experience. That makes it one of the best to learn if you are already working as a developer and want to increase your resume quickly.

The code on Python is designed to be readable. It uses a lot of white spaces, which makes it a pretty easy language to learn while you’re studying it.

One of the most useful Python’s features is its compatibility with data analysis systems and scientific applications. It is a popular language in scientific communities and is often used by researchers to write their programs.

An average Python developer can expect to earn about $100,000 per year. However, there is little room for wage growth.

If you think Python is the best programming language to further your career, consider enrolling in a BitDegree course. The Python Basics Course includes everything you need to know to start writing programs on Python and contains less than four hours of lecture material.

It is best used for back-end web development, desktop applications, and data analysis.


C# is another object-oriented, general-purpose language based on C. It is considered a suitable programming language for building applications native to Microsoft platforms. Microsoft initially developed it as part of its .NET framework for building Windows applications. C# uses a syntax similar to other languages such as C++. Therefore, it is easy to pick it up if you come from a different C family language. 

C# is not only a suitable language for developing Microsoft applications, but also a language used by mobile device developers to build cross-platform applications on the Xamarin platform. Besides, anyone interested in VR development should think about learning C# as it is the recommended language for building 3D and 2D video games using the popular Unity game engine, which produces one-third of the best games on the market.

If mobile application development or virtual reality is your business, consider learning C#. Many mobile device developers use C# to create cross-platform applications on the Xamarin platform. Although it is not the most convenient programming language for beginners. 

If you are interested in any of the above areas, please see the section “Learning the code when making games – Udemy’s Complete Unity Developer in C#.” I see that more than 200,000 students have enrolled in this course, which indicates its popularity.

It is best used for mobile and game development.

What Are the Best Programming Languages to Learn?

Source: Reddit.

As was mentioned at the beginning, there is no best programming language to learn. The best language for you will depend on your experience, your current knowledge and reasons to learn a new language. 

While there are many options, you should be able to narrow down your language choice by what you want to learn from it. 

Remember to consider the following:

  • Programming experience, because some languages, such as Python and Java, are more suitable for beginners who have never programmed before.
  • What you want to do with the language. Different languages are used for different things.
  • How much time do you have? Some languages are much more demanding than others.

Make your choice based on your interests and the type of software development you want to get into. Here is a brief summary:

  • External web development: JavaScript.
  • Internal web development: JavaScript, Java, Python, PHP.
  • Mobile development: Java, C#.
  • Game development: C#.
  • Desktop applications: Java and Python.

To Sum Up

Programming and developer communities are evolving faster than ever.

Various new programming languages are emerging that are suitable for different categories of developers (beginners and experts) as well as for other applications (web applications, mobile applications, game development, distributed systems, etc.).

This list simply scratches the surface of existing programming languages. Still, the simple fact is that with the right coding skills, you will be perfectly prepared to offer valuable technical support and become an asset to any organization.

5 Best Programming Languages to Learn for Cyber Security

Originally published by Dr. Michael J. Garbade on October 17th 2018 136,073 reads1

@ledumjgDr. Michael J. Garbade

Becoming successful as a cyber security expert requires diverse skills. An all-round professional can confidently implement and monitor security measures that guard computer systems against attacks and unauthorized access.

Henrique, a Brazil-based Python expert who teaches people how to create applications using the language, emphasizes that “besides keeping abreast with the latest happenings in the cyber security field, you also need to be acquainted with various programming languages.”

Here are 5 best programming languages to learn to make your cyber security career worthwhile.

1. C and C++

C and C++ are critical low-level programming languages that you need to know as a cyber security professional.

These languages provide access to low-level IT infrastructure such as RAM and system processes, which if not well protected, hackers can easily exploit.

The C programming language is the backbone of most operating systems. It is a lean, flexible, and efficient language that can be used to complete a wide range of tasks such as cryptography, image processing, and socket networking.

Essentially, C++ is usually regarded as C’s big brother — which has been concocted with crack, meth, and steroids and mixed without any favors. C++ is a fantastic language that is largely based on C’s source code.

There are several cyber security programs created using C++. For example, Nmap, the network mapper tool, is created using C++.

Here is a marvelous quote from Bjarne Stroustrup, the creator of C++:

“C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows your whole leg off.”

As a cyber security expert, if you are experienced at using C/C++ programming languages, you’ll know how to respond to attacks targeting lower level operations within your computing environment.

2. Python

Python is a high-level programming language that is increasingly becoming popular among cyber experts.

It’s gaining traction mainly because of its adherence to code readability, clear and simple syntax, and availability of an extensive number of libraries.

So, whatever task you want to do, you can always complete it easily with Python.

For example, you can use the language to send TCP-packets to machines, perform malware analysis, and create intrusion detection systems with minimal reliance on third-party tools.

However, unlike C/C++, Python is not low-level; therefore, it may not provide enough visibility to hardware resources.

Learning Python for cyber security will give you an edge in your career. You’ll be equipped with programming skills that can assist you to identify vulnerabilities and discover how to fix them.

No programming knowledge required

3. JavaScript

JavaScript is a high-level programming language, which is often referred as the “lingua franca” of the web.

JavaScript is a core technology that powers the Internet. Primarily, it’s the language that adds interactivity to web pages.

Although JavaScript was initially implemented only on the client-side in web browsers, it’s now possible to use the language in other types of host infrastructure, such as server-side in databases and offline applications like PDF programs.

Therefore, because of its extensive usage, learning JavaScript can make you go one step ahead of the hackers.

You’ll understand the concepts of how websites and other applications work and the best designs to employ to ward off malicious users.

For example, cross-site scripting is a JavaScript-based attack that involves an attacker implanting malicious code in a web application.

If you are experienced in using the JavaScript programming language, you can prevent such types of attacks from occurring.

4. PHP

PHP is a server-side programming language for developing websites. Because most websites are created using PHP, learning the language will enable you to know how to fend off intruders.

For example, DDoS (Denial-of-service) attacks usually attempt to make web applications unavailable to intended users.

With PHP programming knowledge, coupled with skills in other technologies like JavaScript, you can implement robust solutions to secure web applications.

5. SQL

SQL (Structured Query Language) is mostly used in managing data stored in databases.

Because of the current explosion of data storage systems, SQL is widely used for maintaining and retrieving data.

Similarly, hackers are increasingly orchestrating the language for damaging or exfiltrating the stored data.

For example, SQL injection attacks involve exploiting SQL vulnerabilities to steal or modify data kept in databases.

Therefore, having a good understanding of the SQL language is critical in your cyber security career.

Wrapping up

The above is not an exhaustive list of the best programming languages for cyber security.

Depending on your specific use-case, you may find that one language fits your role better than the others.

For example, if you want to focus on securing the frontend of a web application, learning JavaScript could be your ideal choice.

Nonetheless, to be an all-round cyber geek, you need to employ a reconnaissance-approach: the more languages you learn, the better.

You never know which one could save your day.

Cybersecurity addresses the key aspects confidentiality, authentication, integrity, and availability. This chapter introduces the key terms and technologies used in cybersecurity and then shows some Java programming examples for cybersecurity applications. It explains key concepts such as encryption, hash functions, message digests, digital signatures, and digital certificates. The chapter looks at both private key encryption and public key encryption. It presents some interesting Java security programming resources. The chapter also looks at two case studies demonstrating how to use the encryption technologies in real life. The first example is secure email. Traditional email sends and receives a message as clear, plain text. The second example is secure web. Like email, traditional web services, built on the hypertext transfer protocol, use clear, plain text to send and receive messages.ResearchGate Logo
