LOW
The severity is assessed as LOW because the post does not detail any specific vulnerabilities or exploits but focuses on recommending additional tools for enhancing a network security scanner setup. There are no immediate threats to address, and the content is more informational in nature.

The network security scanner device described aims to integrate tools like Nmap with its NSE scripting engine for active scanning and vulnerability assessment. The primary objective is to scan networks for open ports, outdated software, and other potential attack surfaces while cross-referencing findings with known CVEs. Besides Nmap, several free tools can complement this setup: OpenVAS (Open Vulnerability Assessment System) offers comprehensive network auditing capabilities and integrates with Nessus plugins; Nikto provides web server scanning functions to identify vulnerabilities in web applications; and Lynis is an advanced security scanner for Linux/Unix/BSD systems that checks configurations, software versions, and system integrity. Together, these tools can provide a more thorough network analysis than Nmap alone.

Remediation
  • Install OpenVAS by following the official documentation at https://www.openvas.org/installation.html
  • Configure Nikto for web server scanning using 'nikto -h http://target.com'
  • Run Lynis with default options to check system configurations: 'lynis audit system'
Stack Impact

Minimal direct impact on common homelab stacks, as the recommendation is for enhancing security scanner capabilities rather than addressing an immediate vulnerability. However, integrating these tools can improve network security posture.
