Which approach helps in identifying vulnerabilities within a system?

Penetration testing is an essential approach for identifying vulnerabilities within a system. This method simulates attacks on a system, mimicking the actions of malicious attackers to explore and exploit weaknesses. By conducting penetration tests, security professionals can assess the security posture of a system, uncovering vulnerabilities that may not be apparent through other means. It provides insights into how an attacker might gain unauthorized access, data breaches, or disrupt services within the organization.

The active nature of penetration testing allows organizations to see how their defenses stand against potential threats in real-time, informing necessary improvements to their security measures. This proactive approach is crucial in mitigating risks before they can be exploited by real attackers, making penetration testing a vital component of an organization's security strategy.
