What does a vulnerability scanner typically do?

A vulnerability scanner is designed to identify weaknesses in a system, which is critical for maintaining security. By systematically scanning the network or system for known vulnerabilities, such as outdated software, misconfigurations, or missing patches, these tools can help organizations assess their security posture. This proactive approach allows security teams to address vulnerabilities before they can be exploited by attackers, ultimately enhancing the organization's overall security strategy.

The primary function of a vulnerability scanner focuses on detection rather than mitigation. It does not encrypt data in transit, analyze network traffic in-depth, or automatically remove malware, which are tasks associated with other security tools such as firewalls, traffic analyzers, and antivirus software. Understanding the specific function of vulnerability scanners is essential for applying appropriate security measures in a comprehensive cybersecurity framework.
