Episode 11 - The AI Maturity Journey: Data, Agents, and the Shift from Craft to Art

Richard Bejtlich talks with Vijit Nair, VP of Product at Corelight, about the evolving "AI Maturity Journey" for modern security teams. Vijit outlines a three-level spectrum of AI adoption, moving from basic human-driven assistance to automated swarms of agents, and eventually toward fully autonomous systems. They discuss why high-quality, unopinionated data remains the essential foundation for building trust in AI and how technologies like the Model Context Protocol (MCP) are turning human language into the primary interface for tool integration.

Corelight Agentic Triage demo

Corelight is excited to introduce Agentic Triage! In this demo, you can see how Agentic Triage helps SOC analysts filter through alerts and respond quickly to active threats. We combine generative AI with our industry leading log framework to identify the detections and cases that truly matter. This video shows how you can use Agentic Triage to quickly perform deep dives into open detections and make confident decisions to secure your network.

Episode 9 - Federal Cyber Defense: Legacy Debt, Cloud Shifts, and Network Truth

Richard Bejtlich sits down with Jean Schaffer, Corelight’s Federal CTO, to discuss the unique hurdles facing government agencies in an era of escalating state-sponsored threats. Jean highlights the persistent challenge of legacy IT infrastructure and the "technical debt" that complicates modernization efforts across the Department of Defense, the intelligence community, and the civilian sector. The conversation explores the strategic shift toward cloud adoption as a means to decommission vulnerable on-premise hardware and the evolving "whole of nation" defense strategy that requires deeper public-private partnerships.

Episode 8 - Enterprise Nervous System: Using Network Signal to Direct Business Strategy

In this episode of Corelight Defenders, I’m joined by Bernard Brantley, Chief Information Security Officer at Corelight, as we delve into the concept of the enterprise nervous system. Bernard shares insights from his extensive experience in network analysis, explaining how organizations can leverage their network traffic data to enhance security and drive business outcomes. We discuss the importance of understanding the interdependencies between assets, processes, and goals, and how security teams can position themselves as integral to business success rather than just risk mitigators.

Episode 7 - Practical AI for Zeek, MITRE, and Security Docs

In Episode 7 of Corelight DefeNDRs, join me, Richard Bejtlich, as I sit down with Dr. Keith Jones, Corelight's principal security researcher, to discuss the practical applications of AI in enhancing network security. We delve into how large language models (LLMs) can assist in cleaning up documentation and generating Zeek scripts, sharing insights from our extensive experience in incident response and coding. Keith reveals the challenges and successes he has encountered using LLMs to streamline processes, including their role in analyzing MITRE techniques.

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.

Episode 5 - Detecting DNS Covert Channels in the Wild (Part 1)

In Episode 5 of Corelight Defenders, I, Richard Bejtlich, engage with Corelight's co-founder and chief scientist, Vern Paxson, to delve into the intricate world of DNS covert channels. We explore how adversaries exploit DNS lookups to silently communicate within tightly controlled enterprise environments. Vern explains various methods attackers may use, from encoding data in seemingly benign domain names to manipulating the timing of requests. Our discussion highlights the challenges of detecting these covert channels, especially in the presence of network monitoring.

Episode 4 - Staying Curious: Lessons from 25 Years in Cybersecurity

In Episode 4 of Corelight Defenders, I sit down with Angela Loomis, Corelight's Director of Technical Account Management, to explore her remarkable 25-year journey in cybersecurity. Angela shares her unconventional entry into the field, starting from a background in television production to becoming a leader in security strategy. We delve into the importance of curiosity in cybersecurity, discussing how diverse experiences enrich the profession, and whether formal education might dampen that curiosity.

How to detect React2Shell attacks using network-based threat hunting

How do you find React2Shell vulnerabilities or detect React2Shell attacks in real environments? In this video, Corelight cloud security researcher David Burkett walks through how to threat hunt React2Shell by focusing on post-exploitation behavior at the network level. Instead of relying on exploit signatures, the approach uses application baselining and network traffic analysis to identify abnormal behavior.
