Episode 6 - Detecting DNS Covert Channels in the Wild (Part 2)

In Episode 6 of Corelight DefeNDRs, we delve deeper into the fascinating world of DNS covert channels with Vern Paxson, our chief scientist and co-founder. Continuing from our previous discussion, Vern shares his insights on techniques developed to detect these stealthy channels utilized by intruders to evade security measures. We explore the innovative approach of leveraging time series analysis of DNS lookups, how to distinguish benign traffic from potential threats, and the real-world implications of our findings across significant datasets.

Why One-Time Vulnerability Scans Aren't Enough

A single vulnerability scan provides a tempting snapshot of security health. Too many companies rely on such periodic checks for compliance and some semblance of risk assessment. This, however, leads to an extremely dangerous illusion of security. Modern digital environments, as well as threat actors, move at speeds that are much too high for a static, point-in-time evaluation. Treating cybersecurity as an exercise in box-ticking leaves gaps that adversaries can use.

7 Smart Ways to Improve Security Monitoring With Automation

Security can feel like a constant background concern for anyone who runs a startup or manages product delivery. One missed alert or late response can cause serious damage. Manual monitoring is no longer effective, as it doesn't scale well. Workers get tired, which causes logs to pile up and signals to be easily missed. That is why many businesses are turning to automation.
