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.

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.

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.

Watch this webcast to get the best network evidence for security threats and learn how to.

Network evidence is vital for defense, but collecting it can be overly complicated and result in incomplete data that is difficult to use. By transforming VPC and on-premises traffic into Zeek logs and Suricata alerts, you can accelerate threat hunting and incident response workflows in security analytics tools like Chronicle and VirusTotal.

Poor Operational Technology (OT) security can lead to serious IT data breaches. Learn from experts at Splunk, Corelight, and ClearShark about the risks unsecured OT systems pose to IT networks, and how visibility into network traffic can enable accurate alerting to malicious behavior. You’ll learn key differences between OT and IT networks, about Corelight’s ability to understand and enhance OT protocols, and the value of Zeek wire data for both IT and OT security.
