ABSTRACT:
Information, e.g., a source address, in packets on a network is processed by a geo-location detector The geo-location detector generates a related location identifier, which, for example, is inclusive of one or more source addresses, known or unknown. The location identifier serves as a less precise indicator than the exact location of the system associated with the particular source address of interest, but a more accurate location indicator than was previously available. One of the addresses in a set of source addresses represented by the location identifier is the source address of interest. Although other source addresses represented by the location identifier may not be attacker sources, the location identifier is an identity that can be used as a variable for correlation, trend analysis, or search keys in accessing a network security threat.
