Description Recover from SS7 DoS Attack: If an SS7 Denial of Service (DoS) attack is detected, Service Provider and Network Operators should more aggressively apply the same thresholding and filtering mechanism used to prevent an attack (NRIC BP 8053). The alert/alarm will specify the target of the attack. Isolate, contain and, if possible, physically disconnect the attacker. If necessary, isolate the targeted network element and disconnect to force a traffic reroute.
