How to Spot C2 Traffic on Your Network

Attackers often hide their command and control (C2) activity using techniques like encryption, tunneling in noisy traffic like DNS, or domain generation algorithms to evade blacklists. Reliably spotting C2 traffic requires a comprehensive network security monitoring capability like open source Zeek that transforms packets into connection-linked protocol logs that let analysts make fast sense of traffic. Corelight’s commercial NDR solutions generate this Zeek network evidence and also provide dozens of proprietary C2 insights and detections.

A SANS 2021 Report Top New Attacks and Threat Report

In the SANS 2021 Top New Attacks and Threat Report, John Pescatore provides insight into the threats highlighted during the SANS panel discussion at the 2021 RSA Conference. This webcast will include practical advice from the paper, including insights from SANS instructors Ed Skoudis, Heather Mahalik, Johannes Ullrich, and Katie Nickels on the critical skills, processes and controls needed to protect their enterprises from these advanced attacks.

The Simplest way to Secure your Java Maven Project

Can I scan for security vulnerabilities using Maven? How can I integrate security scanning in my Maven build? How to monitor for security vulnerabilities with every Java build? Scanning the dependencies for known security vulnerabilities in your project is essential. The ideal time to start checking your dependencies is the very moment you import them! To that end, we created the Snyk Maven plugin so you can now scan your application for security vulnerabilities in third-party libraries as part of your build cycle—putting security expertise in the hands of developers.

Encrypted Traffic Collection

Working with encrypted traffic is a common task in the SOC and one that many people think network monitoring solutions can't do anything about. The reality, however, is a bit less cut and dry than you might think. Corelight with Zeek can parse details about the certificate handshake and the SSL connection itself. See the cipher and elliptic curve in use, which are great for detecting vulnerabilities like CurveBall. Learn more about Corelight's Encrypted Traffic collection in this brief two minute video.
