A penetration test (pentest) simulates a cyberattack to identify potential vulnerabilities in a system. Penetration testers, who are ethical hacking experts, use hacking techniques to improve security, not to cause harm. Their main task is to test applications, networks, and other resources, uncovering critical vulnerabilities and enhancing overall protection. While often used interchangeably, “ethical hacking” is a broader concept that also includes other services, such as malware analysis and risk assessment, in addition to penetration testing.
The phases of a penetration test
1
Preliminary research - The team gathers information about the system using methods such as code analysis for apps and network traffic analysis, integrating OSINT resources from everything that can be found on the internet.
2
Attack attempts - Various attack attempts are carried out using methodologies capable of compromising both the client and the server, thus testing the system's overall robustness.
3
Shift left and privilege escalation - Exploiting the available access, testers attempt to expand control by leveraging multiple vulnerabilities to gain higher privileges or broaden the attack perimeter, emulating advanced threats.
4
Final report - At the end, testers provide a report detailing the discovered vulnerabilities, analyzing the impact and exploits used, and offering recommendations to improve security.
Penetration testers use a range of tools to perform analysis, identify vulnerabilities, and automate critical stages of the testing process. Some of the most commonly used tools include:
