BDF For Bruteforce Prevention
BFD is a modular shell script for parsing application logs and checking for authentication failures. It does this using a rules system where application specific options are stored including regular expressions for each unique auth format.
The regular expressions are parsed against logs using the ‘sed’ tool (stream editor) which allows for excellent performance in all environments
