Zeek Network Security Monitor v2.6.2 release: powerful network analysis framework
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
Zeek’s domain-specific scripting language enables site-specific monitoring policies.
Zeek targets high-performance networks and is used operationally at a variety of large sites.
Zeek is not restricted to any particular detection approach and does not rely on traditional signatures.
Zeek comprehensively logs what it sees and provides a high-level archive of a network’s activity.
Zeek comes with analyzers for many protocols, enabling high-level semantic analysis at the application layer.
Zeek keeps extensive application-layer state about the network it monitors.
Zeek interfaces with other applications for real-time exchange of information.
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.
Zeek v2.6.1 releases.
- * Update NEWS/CHANGES (Jon Siwek, Corelight)
* Add missing &optional attr to KRB record fields (Jon Siwek, Corelight)
The KRB parser allowed for the following types/fields to be left uninitialized, so an &optional attribute was added to reflect that:
Usages have also been adapted to perform existence checks.
* Improve PE file analysis (Jon Siwek, Corelight)
* Consider parsing done after processing headers
* Remove the analyzer when done parsing
* Enforce a maximum DOS stub program length (helps filter out non-PE)
* Set PE analyzer CMake dependencies correctly (Jon Siwek, Corelight)
* Add options to tune binpac flowbuffer policy (Jon Siwek, Corelight)
