Vulnerability Scanning
Vulnerability scanning identifies hosts and host attributes (e.g., operating systems, applications, open ports), but it also attempts to identify vulnerabilities rather than relying on human interpretation of the scanning results. Many vulnerability scanners are equipped to accept results from network discovery and network port and service identification, which reduces the amount of work needed for vulnerability scanning.
Also, some scanners can perform their own network discovery and network port and service identification. Vulnerability scanning can help identify outdated software versions, missing patches, and misconfigurations, and validate compliance with or deviations from an organization’s security policy.
This is done by identifying the operating systems and major software applications running on the hosts and matching them with information on known vulnerabilities stored in the scanners’ vulnerability databases.
