What is Penetration Testing?

A penetration test is a simulated attack against an organization in which ethical hackers use many of the same tools, techniques, and procedures as a real attacker would use. By simulating attacks by real-world threats, pen testers can identify vulnerabilities in an organization’s systems and evaluate the effectiveness of security solutions and incident responders. The results of the assessment can then be used to improve enterprise cybersecurity by patching vulnerabilities, closing security gaps, and improving incident response processes.

The Importance of Penetration Testing

Penetration testing is designed to simulate a real-world threat to an organization. By doing so, it provides multiple benefits, including:

How Does Penetration Testing Differ from Vulnerability Scanning?

Penetration testing and vulnerability scanning are both intended to identify vulnerabilities and other security issues. However, they differ significantly in terms of technique and the types of issues that they can detect.

Unlike a penetration test, vulnerability scanning is performed wholly using automated tools. These tools contain databases of signatures of known attacks such as CVEs and vulnerabilities included in the OWASP Top Ten list. The tool assesses whether the target systems may contain these vulnerabilities and generate an automated report describing all discovered vulnerabilities and their severity.

Penetration testing provides deeper insight into an organization’s vulnerabilities than a vulnerability scan. While vulnerability scanning identifies security issues in an organization’s attack surface, penetration testing involves exploiting and combining these vulnerabilities to gain deeper access.

Vulnerability scanning is often part of a penetration test, identifying low-hanging fruit and potential places where a pentester can start their assessment. However, a pentest goes deeper, which provides a better understanding of the impact of various vulnerabilities and helps to eliminate false positive detections.

The Three Ways to Perform a Pentest

Penetration tests can be performed in many different ways using various tools and techniques to assess the security of certain systems. However, all pen tests can be generally divided up into three main categories:

The Penetration Testing Process

A penetration test is a realistic simulation of a real-world attack against an organization. This process includes the following steps:

  1. Scoping: In this stage, the pentester and client define the rules of engagement, such as the systems in scope, allowable attacks, and the objectives of the attack.
  2. Reconnaissance: During this stage, the pentester collects information about their target that is used to identify potential attack vectors.
  3. Scanning and Enumeration: Penetration tests commonly use vulnerability scanning to identify methods to gain initial access to the target environment.
  4. Exploitation: The pentester exploits an identified vulnerability to gain a foothold within the target network. Then, the attacker exploits internal vulnerabilities to move through the network and achieve objectives such as planting a flag on a critical system or gaining access to a privileged account.
  5. Documentation: At this stage, the penetration tester creates and presents a report detailing the assessment, its findings, and how the client can address the identified issues.
  6. Mitigation and Support: After the engagement is complete, the pen testing team works with the organization to mitigate identified security issues.
