SIP Security is a system feature designed to identify SIP attacks. The feature has two methods Static Blacklist and Dynamic Blacklist for securing SIP system services.
Static Blacklist can be defined when a known SIP attack host has been identified and can be added statically to the system to drop all SIP messages from this host.
Dynamic blacklist allows the user to configure a set of rules in which the system will dynamically detect any host that violates these rule types and will then create policies to drop these hosts for a set period of time.
