Vigilante is an open source intrusion detection system (IDS) written in NodeJS. Protege aims to be compatible with existing Snort and mod_security rules
Vigilante requires libpcap to be installed.
$ sudo apt-get install libpcap-dev
To install Vigilante, use npm:
$ npm install -g vigilante --unsafe
Opening the capture interface on most operating systems requires root access, make sure to install/run Vigilante on a user with the right privs!
You can view examples in the example folder.
Vigilante Rule Format
VRF is fully compatible with all Snort expressions, just use the parser to convert any Snort rules to VRF
Standard Snort rule format:
action proto src_ip src_port direction dst_ip dst_port (options)
alert ip $EXTERNAL_NET $SHELLCODE_PORTS -> $HOME_NET any (msg:"SHELLCODE x86 setgid 0"; content:"|B0 B5 CD 80|"; reference:arachnids,284; classtype:system-call-detect; sid:649; rev:8;)
Standard Vigilante rule format:
message: 'attack details to display' protocol: proto source: 'ip range' source_port: port_numbers destination: 'ip range' destination_port: port_numbers parameters: any scan/search specifications
message: 'SHELLCODE x86 setgid 0' protocol: ip source: $EXTERNAL_NET source_port: $SHELLCODE_PORTS destination: $HOME_NET destination_port: any parameters: contains: '|B0 B5 CD 80|'
