Slips: Behavioral Machine Learning-Based Intrusion Prevention System

Slips is a powerful endpoint behavioral intrusion prevention and detection system that uses machine learning to detect malicious behaviors in network traffic. Slips can work with network traffic in real-time, PCAP files, and network flows from popular tools like Suricata, Zeek/Bro, and Argus. Slips threat detection is based on a combination of machine learning models trained to detect malicious behaviors, 40+ threat intelligence feeds, and expert heuristics. Slips gathers evidence of malicious behavior and uses extensively trained thresholds to trigger alerts when enough evidence is accumulated.

Introduction

Slips is the first free software behavioral machine learning-based IDS/IPS for endpoints. It was created in 2012 by Sebastian Garcia at the Stratosphere Laboratory, AIC, FEE, Czech Technical University in Prague. The goal was to offer a local IDS/IPS that leverages machine learning to detect network attacks using behavioral analysis.

Slips is supported on Linux, MacOS, and windows dockers only. The blocking features of Slips are only supported on Linux

Slips is Python-based and relies on Zeek network analysis framework for capturing live traffic and analyzing PCAPs. and relies on Redis >= 7.0.4 for interprocess communication.

Usage

The recommended way to use Slips is on Docker.

Linux and Windows hosts

docker run --rm -it -p 55000:55000  --cpu-shares "700" --memory="8g" --memory-swap="8g" --net=host --cap-add=NET_ADMIN --name slips stratosphereips/slips:latest
./slips.py -f dataset/test7-malicious.pcap -o output_dir
cat output_dir/alerts.log

Macos

In MacOS, do not use --net=host if you want to access the internal container's ports from the host.

docker run --rm -it -p 55000:55000 --platform linux/amd64 --cpu-shares "700" --memory="8g" --memory-swap="8g" --cap-add=NET_ADMIN --name slips stratosphereips/slips_macos_m1:latest
./slips.py -f dataset/test7-malicious.pcap -o output_dir
cat output_dir/alerts.log

Graphical User Interface

To check Slips output using a GUI you can use the web interface or our command-line based interface Kalipso

Web interface
./webinterface.sh

Then navigate to http://localhost:55000/ from your browser.

For more info about the web interface, check the docs: https://stratospherelinuxips.readthedocs.io/en/develop/usage.html#the-web-interface

Kalispo (CLI-Interface)
./kalipso.sh

For more info about the Kalipso interface, check the docs: https://stratospherelinuxips.readthedocs.io/en/develop/usage.html#kalipso

Requirements

Slips requires Python 3.10.12 and at least 4 GBs of RAM to run smoothly.

Installation

Slips can be run on different platforms, the easiest and most recommended way if you're a Linux user is to run Slips on Docker.

Configuration

Slips has a config/slips.yaml that contains user configurations for different modules and general execution.

Troubleshooting

If you can't listen to an interface without sudo, you can run the following command to let any user use Zeek to listen to an interface not just root.

sudo setcap cap_net_raw,cap_net_admin=eip /<path-to-zeek-bin/zeek
