Network Scanning and Security Assessment with Nessus

Nessus, a vulnerability scanning tool, evaluates network security by identifying potential vulnerabilities across operating systems, applications, and services. The process involves configuring the scanner, initiating scans on specific targets, and generating reports with severity-ranked vulnerabilities. Administrators use these reports to prioritize and address issues, enhancing network defense. While Nessus is valuable, regular scanning and ongoing monitoring remain essential for effective security maintenance.

Scanning an individual device or a network provides insights into various details, such as vendor information, operating systems, active ports, and running services. Depending on the chosen scanning tool, potential vulnerabilities may be identified, along with recommended security improvements.
