SRParser 0.0.4

Parse and easily work with Snort rules.

Intro

Snort rule tokenizer and parser written using PLY. This is my first tokenizer, parser and I may make improvements as time goes on. I plan to test it more but it seems to be roughly working and I will release it so it can be tested more. If you have any suggestions, ideas, or improvements feel free to open an issue. Inspiration drawn from plyara.

Usage

pip install SRParser

from SRParser import SnortParser

parser = SnortParser()

data = '''
alert tcp any any -> any 1080 (msg:"TEST"; content:"hostip"; offset:3; depth:12; flags:A; sid:123;)
'''

my_rules = parser.parse_rules(data)

for i in my_rules:
    print(i.__dict__)

{'action': 'alert', 'protocol': 'tcp', 'source_ip': 'any', 'source_port': 'any', 'direction': '->', 'dest_ip': 'any', 'dest_port': '1080', 'body_string': 'msg:"TEST";content:"hostip";offset:3;depth:12;flags:A;sid:123;', 'body_options': [{'msg': '"TEST"'}, {'content': '"hostip"'}, {'offset': '3'}, {'depth': '12'}, {'flags': 'A'}, {'sid': '123'}]}
