Vulnerability Assessment & Penetration Testing: What you need to know
Vulnerability assessment and penetration testing are both important services used to assess the security of a network or system. In many respects, these services are similar to each other, but there are also some key differences between the two.
Vulnerability assessment is a process that involves identifying and assessing vulnerabilities in a network or system. This is usually done using automated tools, such as scanners, that scan for known vulnerabilities in system software and devices. The scan results are then used to create a report that identifies the vulnerabilities and provides recommendations on how to mitigate them. The main goal of a vulnerability assessment is to identify vulnerabilities so that they can be fixed before they are exploited.
Penetration testing, on the other hand, is a more active process that involves trying to exploit vulnerabilities in a system. The main goal of penetration testing is to simulate a real attack on the system and identify vulnerabilities that an attacker can exploit. The procedure is usually done by professional penetration testers, who use a variety of tools and techniques to try to gain unauthorized access to the system. Penetration testing results are then used to create a report that identifies vulnerabilities and provides recommendations on how to mitigate them.
A key difference between vulnerability assessment and penetration testing is the level of interaction with the system. Vulnerability assessment is usually done using automated tools that scan the system without interacting with it, while penetration testing requires active interaction with the system to identify vulnerabilities.
Vulnerability assessment is a passive process, where the controller only looks for vulnerabilities and does not actively try to exploit them, while penetration testing is an active process, where the controller tries to exploit the identified vulnerabilities.
It is also worth noting that penetration testing can also include social engineering attacks that simulate phishing or baiting attacks aimed at finding vulnerabilities in the element of the people in the organization and not just on the technical side.
Both vulnerability assessment and penetration testing have their advantages and disadvantages:
Vulnerability assessment
Advantages:
- It allows organizations to identify and prioritize vulnerabilities so that the most critical ones can be corrected first.
- It can be run regularly to ensure that new vulnerabilities are identified and addressed on time.
- It can be automated, which means that the process can be completed quickly and at a lower cost than penetration testing.
Limitations/Cons:
- It creates false positives, resulting in a large volume of vulnerabilities that are not real vulnerabilities.
- Each vulnerability must be manually tested before being tested again.
- A vulnerability assessment does not confirm whether a vulnerability is exploitable or not.
Penetration testing
Advantages:
- It can help organizations identify vulnerabilities that may not be detected by automated vulnerability assessments.
- It simulates real attacks and provides a clear understanding of how an attacker can try to exploit vulnerabilities.
- It can help organizations identify vulnerabilities in their people, processes, and technology.
- It helps organizations validate the effectiveness of their existing security controls and identify gaps in their security procedures.
- Excludes false positives.
- It is required annually or after major changes in the body.
Limitations/Cons:
- It takes longer than vulnerability assessment and is much more costly.
Both services produce corresponding reports that not only record the vulnerabilities identified but also suggest solutions and best practices to remedy these vulnerabilities. Reports help improve the overall security posture of the organization.
The best practice is for the two services to be combined to achieve optimal network and application security. When vulnerability assessment and penetration testing are combined, they provide a more comprehensive and effective approach to safety assessment. The vulnerability assessment process provides a clear understanding of the weaknesses that exist, while the penetration testing process validates the impact of these weaknesses and provides a measure of the effectiveness of security screenings. Together, they give a more complete picture of an organization’s overall safety picture and can be used to prioritize remediation efforts and measure their effectiveness.
