What is a common tool used for vulnerability scanning?

Vulnerability scanning software is designed specifically to identify, classify, and help remediate vulnerabilities in systems, networks, and applications. This type of software systematically probes systems to uncover potential weaknesses, such as outdated software, unpatched systems, misconfigurations, and security holes that could be exploited by attackers.

The primary function of vulnerability scanning software is to perform comprehensive checks against known vulnerabilities, which are often documented in databases like the National Vulnerability Database (NVD). After scanning, these tools typically generate reports detailing the vulnerabilities found, their severity, and recommended actions for remediation. This facilitates proactive security management by allowing organizations to address vulnerabilities before they can be exploited in a real attack.

In contrast, the other tools mentioned serve different purposes. Network traffic analyzers monitor and analyze data packets flowing through a network but do not assess vulnerabilities directly. Firewall filters control incoming and outgoing traffic based on predetermined security rules, focusing more on controlling access than on identifying vulnerabilities within the systems. Data loss prevention (DLP) software is designed to stop sensitive data from being transmitted outside the organization, thus focusing on data protection rather than vulnerability assessment.
