Reverse shells allow bad actors to bypass network security mechanisms, like firewalls, to perform operating system commands. Firewalls are placed inside the demilitarized zones (DMZs). Firewall rules should be configured to process DENY rules first, followed by ACCEPT rules later to avoid many of these security issues in most cases. Considered as one of the best open-source security scanning utility, Nessus not only inspects the firewall of a host but also detects known application-based vulnerabilities.
