7 courses to learn ethical hacking online

Ethical hacking is the process of attempting to penetrate computer systems and networks with the intention of locating weaknesses and vulnerabilities (real and potential) that could be exploited by malicious hackers. Any information uncovered is then used to improve the system’s security and plug loopholes. Sound interesting? Then an online ethical hacking course is for you.

Ethical hacking is sometimes referred to as penetration testing, intrusion testing, or red teaming. There are many types of hackers, and ethical hackers are usually referred to as white hat hackers. This skill is in high demand and a white hat hacking course can jumpstart your cybersecurity career.

A quick search will yield a ton of results for an ethical hacking course online, but they aren’t all worth your time. We reveal more about our favorite courses below, but if you’re in a rush, here are our top picks for the best ethical hacking courses:

We’ve included a range of course types in our list, but here are some things to think about when deciding on which one to try first:

  • Don’t go in over your head. Some courses assume a certain level of background knowledge, while others are targeted at complete beginners. Choose a course that’s at the right level for you.
  • Consider minimum requirements. Bear in mind that you’ll need specific software to follow some courses, so be prepared to gather some resources if needed.
  • Look for special offers. Paid courses are often of higher quality, but they can get pricey. However, many companies run special offers so you end up paying very little for a superior-quality course.
  • Watch out for scammers. Unethical hackers prey on amateurs, so be careful you don’t sign up with unethical hackers who promise to teach you the ropes.

Is ethical hacking legal?

Yes. In 2015, the Librarian of Congress issued a number of exemptions to the 1998 Digital Millennium Copyright Act which effectively allow white hat hackers to hack software in the name of research and on condition they disclose any vulnerabilities they might find. This controversial topic is increasingly relevant as more everyday items, including vehicles, contain computers.

An ethical hacker must abide by the following (informal) guidelines:

  • Get express (written, preferably) permission to attempt to penetrate an organization’s system.
  • Be respectful of all the company’s rules and policies.
  • Notify the company of all weaknesses and vulnerabilities found.
  • Leave the system in the way it was found, that is do not create any weaknesses that could be exploited at a later date.
  • Keep a written record of what is done on the system.
  • Do not violate the laws of a country by, for example, doing something that breaches copyrights, intellectual property, privacy laws, and so on.

Why take an ethical hacking course?

An organization may hire an ethical hacker to attempt to hack their computer system within certain restrictions set by the company and country law. A company may also train a staff member to perform this role in-house. Sometimes ethical hackers are simply self-proclaimed “geeks” who hack on their own time, but not destructively. These kinds of hackers do it “for the fun of it” and, if they’re bounty hunters, even get paid if they find a loophole in an organization’s system.

If you decide to undergo white hat hacker training, you’ll be in excellent company. For instance, a little-known fact about Sir Timothy John Berners-Lee, best known as the inventor of the World Wide Web, is that he was a hacker in his early years. According to Investopedia, “As a student at Oxford University, Berners-Lee was banned from using the university computers after he and a friend were caught hacking to gain access to restricted areas.”

One of the most notorious white hat hackers in recent times is Kevin Mitnick, described once by the US Department of Justice, as “the most wanted computer criminal in United States history.” After serving time for unlawful hacking, he reformed and became a paid ethical hacking consultant for numerous Fortune 500 companies, as well as for the FBI.

As a career, ethical hacking can be quite lucrative. According to InfoSec Institute, salaries for certified ethical hackers in 2021 ranged from $45,000 to $129,000 USD. An Indeed survey from the same year found that ethical hacking salaries ranged from approximately $57,787 per year for an IT security specialist to $105,973 per year for a firewall engineer.

The Exabeam 2018 Cyber Security Professionals Salary and Job Report found that 23.7 percent of security professionals surveyed had a CEH certification (more on that below).

Ethical hacking course certification

The most widely recognized ethical hacking credential is the Certified Ethical Hacker (CEH) credential from EC-Council. You don’t have to sign up for their course before taking the exam, but all self-study students have to go through a formal eligibility process. You could take one or more of the courses listed above and go for the accreditation separately.


The EC-Council also offers the Certified Network Defense Architect (CNDA) credential. To be eligible for the course, you need to first obtain CEH certification from EC-Council and must be employed by a government or military agency, or be a contract employee of the US government.

The essential skills to becoming a master hacker

Unless you specialize in a particular area, for example, mobile or forensics, a formal one-size-fits-all course typically touches on the following subject matter:

  • Buffer overflows, cryptography, denial of service, enumeration, firewalls, exploitation, fingerprinting, foot printing, hacker types, hacking mobile platforms, hacking web applications, hacking web servers, penetration testing, reconnaissance, scanning networks, session hijacking, sniffing, social engineering, sql injection, system hacking, tcp/ip hijacking, hacking tools, trojans and backdoors, viruses and worms, and wireless hacking.

Succinctly summed up by OCCUPYTHEWEB, to get started, here’s what you really need to master:

  • Basic computer skills (not just MS Word but using the command line, editing the registry, and setting up a network
  • Networking skills (for example, understanding routers and switches, internet protocols, and advanced TCP/IP)
  • Linux skills (these are non-negotiable)
  • Hacker tools (for example, Wireshark, TcpDump, and Kali Linux)
  • Virtualization
  • Security concepts and technologies (such as SSL, IDS, and firewalls)
  • Wireless technologies
  • Scripting (for example, Perl, BASH, and Windows PowerShell)
  • Database skills (starting with SQL)
  • Web programming and applications (how hackers target them)
  • Digital forensics
  • Cryptography (encryption)
  • Reverse engineering

Other ethical hacking resources

Formal ethical hacking courses are ideal for on-the-job training in a specific niche. Alternatively, many hackers advocate self-learning. The advantage of this is that you get to discover your field of particular interest. Below are some other free resources, tutorials, hands-on challenges, and articles on ethical hacking.

  • Hacking Tutorial – Access this site with care; some of these tips and tricks are questionable, if not downright illegal. The reason we include it is that one of the responsibilities of an ethical hacker is to know what their evil counterpart is up to.
  • Hack This Site – A free, safe, and legal training ground for hackers to test and expand their hacking skills. Includes an IRC channel where you can hook up with fellow white hatters and ask questions.
  • Exploit Exercises – As the name suggests, see if you can spot code vulnerabilities in a series of advanced hacking challenges.
  • Vuln Hub – This site offers a really fun way to practice your skills in hands-on workshops, for example, download a custom VM and then try to obtain root level access.
  • YouTube – Perfect for the lazy ethical hacker; all you need is popcorn. Simply search “ethical hacking course.”
  • Tutorials Point – The Ethical Hacking Tutorial provides a good overview for beginners.
  • Open Security Training – The Hacking Techniques and Intrusion Detection course is under a Creative Commons License so you can use it to train employees in-house. All the materials are supplied; just add an instructor. The course creator is available for on-site training.

To enhance your learning experience, you might consider joining an ethical hacking forum or paying an ethical hacker to share their knowledge and experience with you. If you’re interested in a particular tool or platform, most hacking software vendors provide in-depth tutorials for their applications.

Happy hacking and stay legal!
