A Cloud of My Own includes the incredibly power IDS tool – Zeek. Zeek (formally called Bro-IDS) was built by two of the preminer eduational institutes involved in high end computing. –
International Computer Science Institute in Berkeley, CA; and the National Center for Supercomputing Applications in Urbana-Champaign, IL.
It was built in the real-world, and has been improved continuously over 15 of real world experience in protecting real networks.
“While focusing on network security monitoring, Zeek provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Zeek has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyberinfrastructure. Zeek’s user community includes major universities, research labs, supercomputing centers, and open-science communities.
Zeek has originally been developed by Vern Paxson, who continues to lead the project now 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.”
