As Zeek now supports Windows, this repository has been archived. Specific build and packaging steps for Zeek's inclusion with Brimcap and Zui are now covered in the build-zeek repository.
This fork of Zeek was created by the development team at Brim Data for inclusion with Brimcap and the Brim desktop app. Most of the changes relative to mainline Zeek relate to support on Windows for generating Zeek logs from pcaps.
Community contributions are welcomed to assist with upstreaming the changes to mainline Zeek. Issue zeek/951 tracks this effort. As mainlining efforts have seen minimal traction thus far, help would also be appreciated in getting the changes to to work with newer Zeek releases, as the Zeek version on which this fork was based is now quite old.
A powerful framework for network traffic analysis and security monitoring.
