Some Zeek behavior can be tweaked through the use of environment variables in the
.env files beginning with
Other changes to Zeek’s behavior could be made by modifying local.zeek and either using a bind mount or rebuilding the
zeek Docker image with the modification. See the Zeek documentation for more information on customizing a Zeek instance. Note that changing Zeek’s behavior could result in changes to the format of the logs Zeek generates, which could break Malcolm’s parsing of those logs, so exercise caution.
The easiest way to add a new Zeek package to Malcolm is to add the git URL of that package to the
ZKG_GITHUB_URLS array in zeek_install_plugins.sh script and then rebuilding the
zeek Docker image. This will cause the package to be installed (via the
zkg command-line tool). See Parsing new Zeek logs on how to process any new
.log files if the package generates them.
