Can Bro use Snort signatures?
Bro includes Snort-compatibility support. The Bro distribution includes a script, snort2bro, which converts a set of Snort signatures into Bro signatures. Along with translating the format of the signatures, snort2bro also incorporates a large number of enhancements to the standard set of Snort signatures to take advantage of Bro’s additional contextual power and reduce false positives.
