Cisco Configuration Modification for Adversary Tactics
This rule detects modifications to Cisco device configurations that could be used by an adversary for persistence, privilege escalation, or to impact system availability. Specifically, it looks for commands related to enabling HTTP/HTTPS servers, configuring Kron jobs (scheduled tasks), modifying access lists, archiving configurations, and setting NTP servers. These commands, if used maliciously, can allow an attacker to maintain access, execute arbitrary commands, control network access, or disrupt time synchronization.
