RITA

From: https://github.com/activecm/rita

RITA is an open source framework for network traffic analysis.

The framework ingests Zeek Logs, and currently supports the following analysis features:

Beaconing: Search for signs of beaconing behavior in and out of your network

DNS Tunneling Search for signs of DNS based covert channels

Blacklisted: Query blacklists to search for suspicious domains and hosts

URL Length Analysis: Search for lengthy URLs indicative of malware

Scanning: Search for signs of port scans in your network

We can add RITA to Security Onion to enhance its current capabilities and leverage the great work from the folks at Active Countermeasures. They’ve done a fantastic job of allowing RITA to be easy to integrate with Security Onion.

Warning

Please keep in mind we do not officially support RITA, so installation is at your own risk.

Additionally, RITA currently only supports use of Zeek logs in TSV format. If you are running the latest version of Security Onion, you will need to switch from JSON to TSV format by following the steps here:

Zeek#tsv
