Zeek Comes to Defender

Microsoft with Corelight support added Zeek integration to Defender for Endpoint, which helps to reduce the time required to detect network-based threats. Zeek is an open-source tool that monitors network traffic packets to uncover malicious network activity. Defenders can scan inbound and outbound traffic. The Zeek integration also allows Defender to detect attacks on nondefault ports, show alerts for password spray attacks, and identify network exploitation attempts such as PrintNightmare.

Zeek will not be a complete replacement of traditional network detection and response technology,it is designed to act as a complementary data source providing network signals.
