Five Security Vulnerabilities Ethical Hacking Can Uncover

While the term “ethical hacking” may sound like an oxymoron, ethical hackers are an incredibly valuable resource for organizations today. Whereas malicious hacking is harmful, ethical hacking is beneficial—when done right, it can protect a company’s digital assets and ensure the security of its network.

As a result, ethical hacking skills are in high demand today: A recent report projects that there will be 3.5 million cybersecurity job openings by 2025 (Cybersecurity Ventures, 2021), and ethical hackers in the United States make an average of $102,400 per year (, 2021). If you’re looking to develop your ethical hacking skills and become a Certified Ethical Hacker (C|EH), now is the perfect time.

An ethical hacker’s job is to attempt to break into a company’s network, understand its security protections and precautions, and identify weaknesses (EC-Council, 2021c). After doing so, they present the company with a list of its security vulnerabilities as well as recommendations for improving security. Ethical hacking often goes hand in hand with other security measures, like penetration testing (EC-Council, 2021b).

In the course of their work, ethical hackers can find many types of network and security vulnerabilities. In this article, we’ll outline five major security vulnerabilities that ethical hacking can reveal.

1. Security Misconfigurations

Security misconfigurations happen when an organization improperly configures or fails to properly utilize all of a system’s security settings, enabling hackers to gain access to its network. A security misconfiguration is often a precursor to a powerful and aggressive attack on a network. Programs like the C|EH train ethical hackers to spot security misconfigurations and then provide recommendations for how a business can remedy them.

2. Injection Attacks

In an injection attack, a malicious actor injects a line of code into a program to gain remote access to an organization’s network (IBM, 2014). Injection attacks are often precursors to larger-scale cyberattacks on a database or website (IBM, 2014). However, appropriate security protocols can stop the malicious injection of code and, if enforced correctly, alert a network administrator. There are many types of injection attacks, with SQL injections among the most prevalent and damaging.

3. Vulnerable System Components 

One of the fundamental challenges in network security is ensuring that all aspects of a network’s systems are secure and up to date—a network is only as secure as its individual components. Using components with known vulnerabilities can create serious network security problems. Ethical hackers can identify these vulnerabilities and determine how to fix them. These fixes may include making improvements to existing security programs and providing recommendations for better security software.

4. Social Engineering

Malicious actors use social engineering tactics to break into an organization’s network by inducing individuals to provide information that enables the hacker to gain illicit access to the organization’s systems (National Institute of Standards and Technology, n.d.). Social engineering attacks may involve, for example, a malicious actor posing as a network administrator and sending out a phishing email to an organization’s members. If users are tricked into giving out their usernames and passwords, the attacker can gain unlawful access to the company’s network. 

Ensuring that employees are aware of social engineering and phishing techniques can lower the odds that such attacks will be successful (EC-Council, 2021a). A company is only as strong as its weakest link. Ethical hacking can help identify these weak links.

5. Authentication Vulnerabilities

Although every network has an authentication process, some networks have particular vulnerabilities that allow a skilled hacker to bypass these authentication measures and breach the network. A C|EH is trained to know what these vulnerabilities are, where to find them, and how to spot them.

How Can You Become an Ethical Hacker?

Ethical hackers are in high demand and can do businesses and nonprofits a great service. When implemented well, ethical hacking can help organizations learn how to prevent security breaches and secure their networks. If you’re interested in helping organizations improve their computer and network security—and obtaining an in-demand, highly compensated job—an ethical hacking certification like the C|EH is an excellent investment in your future. As an ethical hacker, you’ll have the opportunity to help defeat malicious hackers seeking to take advantage of computer vulnerabilities.

At EC-Council, we know that ethical hackers play a vital role in organizations’ security. If you’re looking to hone your ethical hacking skills and advance your cybersecurity career, enroll in EC-Council’s C|EH program, where you’ll learn how to spot issues like security misconfigurations, vulnerabilities to injection attacks, and more.
