List of the best computer and network security online course

1. StationX VIP Membership

StationX offers almost 100 courses related to cybersecurity, including those teaching ethical hacking, penetration testing, networking, security coding, digital forensics, and incident response. It even has courses centered around passing top security certifications and preparing for examinations.

The StationX VIP Membership gives you unlimited access to all courses, many of which have racked up thousands of great reviews. Considering each course normally costs $90–$2,000 by itself, the discounted fee of $149 (usually $1,199) per year for access to all courses is well worth it. You can stream and download lectures and access them from mobile or desktop. You’ll learn at your own speed and receive a certificate of completion for each course.

All-in-all, this is a training toolbox that can serve you well as you embark on a career in the industry. Since it’s updated regularly, you can use it to stay on top of advances in cybersecurity and propel yourself further in your career.

Even if you’re not pursuing a career in the field, this might still be a good fit. Because you can tailor your learning, this membership is suitable for someone looking to take control of cybersecurity within their own company, or even someone who is simply interested in learning more about the field.

2. Coursera Introduction to Cyber Security Specialization

The way Coursera works is it presents multiple courses as part of a specialization. You can take all courses within a specialization or choose specific ones. Each specialization includes a hands-on project which you’ll have to complete in order to earn a certificate.

The Introduction to Cyber Security specialization includes four courses:

  • Introduction to Cyber Attacks: Provides a basic understanding of threats and vulnerabilities, and an overview of how cyberattacks are carried out.
  • Cyber Attack Countermeasures: Teaches the basics of cyber defense and cryptography, including authentication solutions and public-key cryptography.
  • Real-Time Cyber Threat Detection and Mitigation: Discusses real-time cybersecurity techniques and how to detect and prevent common attacks.
  • Enterprise and Infrastructure Security: Introduces more advanced topics such as enterprise compliance frameworks and issues in blockchain and mobile security.

This set of courses goes beyond the basics, so is less suitable for home users looking to boost their cybersecurity knowledge and more for business owners or would-be cybersecurity professionals. The suggested time frame is nine hours per week for two months.

You can take many individual Coursera courses for free. However, to complete a specialization and its corresponding hands-on project to get a certificate, you’ll have to pay a monthly fee. Specializations come with a seven-day free trial after which they cost between $39 and $79 per month for each specialization. This means the quicker you get through the courses and projects, the less you have to pay.

Once you’re finished with this specialization, there are other related ones you can undertake, such as Cybersecurity for Business and Applied Cryptography.

3. Cyber Aces Online

SANS Cyber Aces Online courses are offered for free by the SANS Institute, which you’ve no doubt heard of if you’re in any way interested in cybersecurity. This organization is highly regarded in the field of information security and has been conducting research and education programs for three decades.

The institute runs in-person training events across the globe, but these typically cost thousands of dollars a pop. As such, to get some free online training from these guys is a treat. That being said, the current offerings are limited with just one course being available. But if you’re just looking for a taster, it could be ideal.

The course teaches the fundamentals of cybersecurity, covering the following:

  • Operating Systems: Focusing on command line usage, this module teaches concepts and commands in Linux and advanced use of Windows.
  • Networking: This covers the fundamentals of computer attacks and corresponding defense from a network point of view. You’ll find out about the protocols used in each OSI layer, in particular, the networking layer.
  • System Administration: The final module teaches administrative functions in popular scripting environments.

You can opt to take courses with or without quizzes, which are presented in a multiple-choice format and test knowledge and understanding of each module.

This course is geared toward a prospective cybersecurity professional or members of the general public. The SANS Institute hopes that by offering courses like this for free, people will be better educated on cybersecurity, and it will ultimately “help strengthen the security of our nation.”

4. edX Essentials of Cybersecurity

edX is a great resource for accredited university courses. These courses are designed by various universities themselves and come with verified certificates. However, they do come at a cost. The Professional Certificate in Essentials of Cybersecurity is offered by the University of Washington (UWashingtonX) and costs $796.

The suggested duration for the whole program (which includes four introductory courses) is 2–5 hours per week for 16 weeks.

Included courses are:

  • Introduction to Cybersecurity: Answers questions about and provides literacy in the field of cybersecurity.
  • Cybersecurity: The CISO’s View: Delves into cybersecurity operations and in particular what a Chief Information Security Officer (CISO) does within a company.
  • Building a Cybersecurity Toolkit: Teaches the skills needed to become a cybersecurity professional.
  • Finding Your Cybersecurity Career Path: Discusses the various career paths you could follow and helps you decide which is the right fit for you.

Each course separately costs $99 so you save around $40 by buying the bundle. As you can see, the flow of this program is tailored to someone who is thinking of pursuing a career in the cybersecurity field.

Once you’ve completed this one, if you’re looking for something more advanced, the MicroMasters® Program in Cybersecurity might be of interest. It’s fairly pricey at $1,080, but the length and scope of this course are no doubt worth it. It’s run by the highly-regarded Rochester Institute of Technology and is aimed at learners looking to launch their cybersecurity career.

5. Heimdal Cyber Security for Beginners

Heimdal Security is a reputable firm providing technologies and intelligence in the fight against cybercrime. Heimdal is offering its handy Cyber Security for Beginners course free of charge. While many of the courses on this list are aimed at prospective cybersecurity professionals, this one is targeted more toward a general user looking to bump up their home cybersecurity.

This course is paced for you as lessons are delivered to your inbox every two days. Over the course of 20 lessons, you’ll learn:

  • Cybersecurity basics such as vocabulary and setting up a security system
  • Tools and tactics that can shield you from malware
  • How to make your system less vulnerable to cyber threats
  • How to keep your kids and other loved ones safe online
  • How to explore the web safely (including email and social media)

A few example lesson titles are “No more technical gibberish! Master basic security terms in 20 minutes,” “Share. Tweet. Protect. Repeat. – social media, the safe way,” and “What your kids & parents need to learn about cyber security.” You can see that this really is geared toward the home user and will be less relevant for someone looking to pursue a career in cybersecurity.

6. Cybrary Introduction to IT and Cybersecurity

If you’re debating a career in cybersecurity and thinking about which route to take, this course could be a good fit for you. Designed to help you make a decision between the main areas of cybersecurity, it covers four of the primary disciplines in a modular format than spans just over four hours worth of videos.
