What is the function of a vulnerability scanner?

A vulnerability scanner is specifically designed to identify known vulnerabilities in systems or applications. It scans the network or software to detect weaknesses that could potentially be exploited by attackers. This includes checking for outdated software versions, misconfigured settings, and known security flaws, often using a database of vulnerabilities that have been documented.

By recognizing these vulnerabilities, organizations can take proactive steps to remediate them, thereby reducing the risk of exploitation. This function is essential in maintaining the security posture of an organization and is a critical component of security practices.

While identifying unknown risks, assessing compliance with security policies, and monitoring real-time incidents are all important areas of security management, they fall outside the fundamental purpose of a vulnerability scanner. These activities typically involve a broader scope of analysis and strategy beyond the specific task of pinpointing known vulnerabilities.
