Description: Optional ip address and ports on a monitored interface. The 'locality' attribute is a string that indicates the relative location of the ip address within the network mapping, such as whether the address falls within the address range of a protected network. The optional 'proxy' attribute is 'true' if the sensor has reason to suspect that the address given is not the address of the true attacker. This could be a the result of address spoofing or because the host has been compromised and is acting as a 'zombie'. The 'proxy' attribute may be omitted if and only if its value is false.
