Zeek 5.0.3
Posted Nov 9, 2022
Authored by Robin Sommer, Vern Paxson | Site zeek.org

Zeek is a powerful network analysis framework that is much different from the typical IDS you may know. 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 cyber-infrastructure. Zeek's user community includes major universities, research labs, supercomputing centers, and open-science communities. This is the source code release.

Changes: Fixed an issue where a specially-crafted FTP packet can cause Zeek to spend large amounts of time attempting to search for valid commands in the data stream. Fixed a possible overflow in the Zeek dictionary code that may lead to a memory leak. Fixed an issue where a specially-crafted packet can cause Zeek to spend large amounts of time reporting analyzer violations. Fixed a possible assert and crash in the HTTP analyzer when receiving a specially-crafted packet. Fixed an issue where a specially-crafted HTTP or SMTP packet can cause Zeek to spend a large amount of time attempting to search for filenames within the packet data. Fixed two separate possible crashes when converting processed IP headers for logging via the raw_packet event handlers. Various other bug fixes.

Falco 0.33.0
Posted Oct 20, 2022
Authored by Sysdig | Site sysdig.org

Sysdig Falco is a behavioral activity monitoring agent that is open source and comes with native support for containers. Falco lets you define highly granular rules to check for activities involving file and network activity, process execution, IPC, and much more, using a flexible syntax. Falco will notify you when these rules are violated. You can think about falco as a mix between snort, ossec and strace.

Changes: A dozen major changes, about 2 dozen minor changes, and a handful of bug fixes.
