This Zeek script framework communicates with the Zeek Agent to perform live queries against the agent's tables and then incorporate the results back into Zeek's processing & logging. In addition to tables built in, the agent can connect to Osquery to retrieve any of the host data provided there.
Note: This framework is still a work in progress and expected to change further in terms of API, functionality, and implementation.
The framework requires Zeek 3.0+, which you can download and install per the instructions on the Zeek web site.
You will also need to install the Zeek Agent itself, as well as optionally Osquery, according to these instructions.
The easiest way to install the
zeek-agent framework is through the
If you have not installed the package manager yet, do that first:
# pip install zkg # zkg autoconfig # zkg install zeek/zeek-agent-framework
Alternatively, you can clone the repository manually and copy it over
# git clone https://github.com/zeek/zeek-agent-framework # cp -a zeek-agent-framework/zeek-agent $(zeek-config --site_dir)
If you'd rather run it directly out of the local repository clone
site), set your
# export ZEEKPATH=<path/to/zeek-agent-framework>:$(zeek-config --zeekpath)
Using any of the three installation methods above, you can now load the framework when you start Zeek:
# zeek zeek-agent
Once you start up any agents, you should start seeing a new Zeek log
zeek-agent.log that records the hosts connecting to Zeek:
# cat zeek-agent.log #fields ts source peer level message 1576768875.018249 local ZeekMaster info Subscribing to zeek announce topic /zeek/zeek-agent/zeek_announce 1576768875.018249 local ZeekMaster info Subscribing to zeek individual topic /zeek/zeek-agent/zeek/C6EAF3CFDF46831E2D9103E5A1C48F78AD873A00#10223 1576768877.709030 local ZeekMaster info Incoming connection established from C6EAF3CFDF46831E2D9103E5A1C48F78AD873A3C#7503
You won't see much more at first as there's nothing sending queries to
the endhost yet. Check out the
