This detection rule identifies changes to SNMP community strings on Cisco devices, which can indicate potential malicious activity, such as attackers trying to gain persistent access or exfiltrate sensitive information. Specifically, it looks for commands configuring SNMP community strings with read-write (rw) or read-only (ro) permissions, and changes to the SNMP host configurations. Given that attackers often modify these settings after gaining access to establish unauthorized monitoring capabilities, detecting such modifications is crucial for maintaining network security.
