Script and library for the viewing and filtering of Suricata and Snort rulesets based on interpreted key-value pairs present in the metadata keyword within each rule.
Aristotle is a simple Python program that allows for the filtering of Suricata and Snort rulesets based on interpreted key-value pairs present in the metadata keyword within each rule. It can be run as a standalone script or utilized as a module.
Aristotle takes in a ruleset and can provide statistics on the included metadata keys. If a filter string is provided, it will also be applied against the ruleset and the filtered ruleset outputted.
Aristotle is compatible with Python 2.7 and Python 3.x.
|In order for Aristotle to be useful, it must be provided a ruleset that has rules with the metadata keyword populated with appropriate key-value pairs. Aristotle assumes that the provided ruleset conforms to the BETTER Schema.|
pip install -r requirements.txt
Or if using as a module:
pip install aristotle
And refer to Aristotle as a Module.
usage: aristotle.py [-h] -r RULES [-f METADATA_FILTER] [--summary] [-o OUTFILE] [-s [STATS [STATS ...]]] [-i] [-q] [-d] optional arguments: -h, --help show this help message and exit -r RULES, --rules RULES, --ruleset RULES path to rules file or string containing the ruleset (default: None) -f METADATA_FILTER, --filter METADATA_FILTER Boolean filter string or path to a file containing it (default: None) --summary output a summary of the filtered ruleset to stdout; if an output file is given, the full, filtered ruleset will still be written to it. (default: False) -o OUTFILE, --output OUTFILE output file to write filtered ruleset to (default: <stdout>) -s [STATS [STATS ...]], --stats [STATS [STATS ...]] display ruleset statistics about specified key(s). If no key(s) supplied, then summary statistics for all keys will be displayed. (default: None) -i, --include-disabled include (effectively enable) disabled rules when applying the filter (default: False) -q, --quiet, --suppress_warnings quiet; suppress warning logging (default: False) -d, --debug turn on debug logging (default: False)
