Zeek Network Security Monitor: powerful network analysis framework

by ddos · Published · Updated

Zeek Network Security Monitor

Zeek is a powerful framework for network analysis and security monitoring. It is a powerful system that on top of the functionality it provides out of the box, also offers the flexibility to customize analysis pretty much arbitrarily.

Network Security Monitor

Feature

  • Adaptable

    Zeek’s domain-specific scripting language enables site-specific monitoring policies.

  • Efficient

    Zeek targets high-performance networks and is used operationally at a variety of large sites.

  • Flexible

    Zeek is not restricted to any particular detection approach and does not rely on traditional signatures.

  • Forensics

    Zeek comprehensively logs what it sees and provides a high-level archive of a network’s activity.

  • In-depth Analysis

    Zeek comes with analyzers for many protocols, enabling high-level semantic analysis at the application layer.

  • Highly Stateful

    Zeek keeps extensive application-layer state about the network it monitors.

  • Open Interfaces

    Zeek interfaces with other applications for real-time exchange of information.

  • Open Source

    Zeek comes with a BSD license, allowing for free use with virtually no restrictions.

While focusing on network security monitoring, Zeek provides a comprehensive platform for more general network traffic analysis as well. Well-grounded in more than 20 years of research, Zeek has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally by both major companies and numerous many educational and scientific institutions for securing their cyberinfrastructure.

Zeek was originally developed by Vern Paxson. Robin Sommer now leads the project, jointly with a core team of researchers and developers at the International Computer Science Institute in Berkeley, CA; and the National Center for Supercomputing Applications in Urbana-Champaign, IL.
