Today, as a part of our v27 software release, we are launching enhanced IDS rules management functionality, extending analyst visibility around hosts, devices, users, and more, and upgrading the Corelight Software Sensor to give customers more NDR deployment flexibility.

As we shared at ZeekWeek 2022 in October, we’re thrilled to announce emerging support for Zeek on Windows, thanks to an open-source contribution from Microsoft. Part of its integration of Zeek into its Defender for Endpoint security platform, this contribution provides fully-native build support for Windows platforms and opens up a range of future technical possibilities in this vast ecosystem.

On Nov. 22, 2022 Microsoft announced research findings about an ongoing supply chain attack against IoT devices running Boa web servers. The Boa web server, an open-source small-footprint web server suitable for embedded applications, was discontinued in 2005, but many software development kits still use this lightweight server on IoT hardware. Since being discontinued, vulnerabilities were discovered in Boa that make every version out there exploitable.

The Corelight Labs team prides itself on the ability to create novel Zeek and Suricata detection content that delves deep into packet streams by leveraging the full power of these tools. However this level of additional sophistication is not always required: sometimes there are straightforward approaches that only require queries over standard Zeek logs. It’s always valuable when developing detections to keep in mind that “sometimes simple does just fine.”

As organizations continue to rapidly adopt cloud services, they struggle to expand network detection and response (NDR) capabilities to their hybrid and multi-cloud environments. Network visibility is critical for security operations center (SOC) teams to secure their cloud environments and ensure they can elevate threat detection and incident investigation capabilities. However, traditional NDR solutions require management, configuration and often lack the security context needed.

“Knowing what’s on your network is the first step for any organization to reduce risk.” -CISA Director, Jen Easterly. On October 3, the Cybersecurity and Infrastructure Security Agency (CISA) issued Binding Operational Directive (BOD) 23-01: Improving Asset Visibility and Vulnerability Detection on Federal Networks.
