ABSTRACT:
Method and apparatus for processing log data produced by a network is described. In one example, entries in the log data are filtered using a plurality of filters to select first entries from the entries. The first entries are filtered using a plurality of false positive filters associated with the plurality of filters to select second entries from the first entries. Unique IP addresses are identified in the second entries. The entries in the log data are then filtered using the unique IP addresses to select third set entries. The third entries are analyzed to detect one or more patterns.
