Claim:
1. A security management system for tracking a plurality of assets in a network using a plurality of attributes, the security management system comprising: an asset database operable to store a plurality of asset entries, wherein one or more of the plurality of asset entries have asset entry values for at least one of the plurality of attributes; and an asset correlation engine in communication with the asset database, the asset correlation engine operable to receive a data chunk associated with a target asset included in the plurality of assets; wherein the asset correlation engine is further operable to parse the data chunk to determine data chunk values for at least one of the plurality of attributes; wherein the asset correlation engine is further operable to scan the asset database using the data chunk values and a correlation metric to find a matching asset entry that corresponds with the target asset, thereby determining that the data chunk is associated with the target asset; wherein the asset correlation engine is further operable to determine asset scores for at least some of the plurality of asset entries using the correlation metric, and wherein the asset correlation engine finds the matching asset entry by comparing the asset scores; wherein the correlation metric comprises a plurality of attribute weights corresponding to the plurality of attributes, wherein at least some of the plurality of attributes weights are used to calculate the asset scores, wherein the plurality of attributes comprises a strongly correlated attribute and a loosely correlated attribute, and wherein the strongly correlated attribute has a larger attribute weight than the loosely correlated attribute; and wherein the plurality of attributes further comprises a moderately correlated attribute having an attribute weight that is smaller than that of the strongly correlated attribute and larger than that of the loosely correlated attribute, wherein the attribute weight of the highly correlated attribute is 1.5 to 40 times as large as the attribute weight of the moderately correlated attribute; and wherein the attribute weight of the moderately correlated attribute is 1.5 to 25 times as large as the attribute weight of the loosely correlated attribute.
