Tuning of data loss prevention signature effectiveness

Abstract

In at least one embodiment, a method and a system include capability to fine-tune a data loss prevention system. An example system includes a computer readable storage medium for storing at least one alert database and at least one associated signature set to each alert database; an analytics module in communication to the computer readable storage medium, the analytics module analyzes at least one alert database present on the computer storage medium to determine whether any signatures from the signature set associated with the alert database being analyzed are ineffective based at least on a ratio of valid alerts to false positive alerts for individual signatures selected from a group including a plurality of signatures present in the signature set; and an adjustment module in communication to the computer readable storage medium and the analytics module, the adjustment module removes at least one ineffective signature from the signature set.
