Schrödinger's Detection: Finding the "Zombie" Rules in Your SIEM
Presented sigma-lens, a detection rule analyzer I built, and the results of auditing 2,000+ SigmaHQ and Elastic cloud detection rules: 1 in 3 contained significant quality defects, including rules referencing log fields that do not exist.
Building the Cross-Cloud Kill Chain: A DE's Playbook for AWS, Azure & GCP Detections
A detection engineering playbook for tracing attackers pivoting across AWS, Azure and GCP: cross-cloud TTPs, mapping CloudTrail, Entra ID and GCP audit logs to kill chain stages, and correlation rules that stitch the full attack together.
When Machines Attack Machines: Detecting AI-Autonomous Cloud Compromise at NHI Scale
Detecting autonomous AI agents compromising cloud environments at non-human identity scale, where attacks move at machine speed and traditional identity detections fall behind.
Zero Signal: Operating Where Defenders Can't See
Hands-on session on intrusion paths that generate zero endpoint signal: valid credentials, identity and OAuth abuse, and cloud management APIs, and why the average cloud breach still takes 143 days to detect.
Zero to Scale: A Detection Engineering Primer
The detection engineering lifecycle end to end: translating threat behavior into durable detection logic, deploying across high-volume pipelines, cutting false positives, and assessing detection program maturity.
