Zeek Analysis Tools (ZAT)

The ZAT Python package supports the processing and analysis of Zeek data with Pandas, scikit-learn, Kafka, and Spark

Install

pip install zat
pip install zat[pyspark] (includes pyspark library)
pip install zat[all] (include pyarrow, yara-python, and tldextract)

Why ZAT?

Zeek already has a flexible, powerful scripting language why should I use ZAT?

Offloading: Running complex tasks like statistics, state machines, machine learning, etc.. should be offloaded from Zeek so that Zeek can focus on the efficient processing of high volume network traffic.

Data Analysis: We have a large set of support classes that help bridge from raw Zeek data to packages like Pandas, scikit-learn, Kafka, and Spark. We also have example notebooks that show step-by-step how to get from here to there.

Analysis Notebooks

• Zeek to Scikit-Learn
• Zeek to Parquet
• Zeek to Spark
• Spark Clustering
• Zeek to Kafka
• Zeek to Kafka to Spark
• Clustering: Picking K (or not)
• Anomaly Detection Exploration
• Risky Domains Stats and Deployment
• Zeek to Matplotlib
