Explore the innovative practice of Security Chaos Engineering in this 13-minute conference talk that demonstrates how to intentionally inject failures and simulate attacks to uncover hidden security weaknesses before adversaries exploit them. Learn to apply chaos engineering principles beyond traditional reliability contexts to proactively test security assumptions and strengthen system defenses. Discover practical applications using open source tools including ChaosMesh, LitmusChaos, and KubeArmor through real-world scenarios such as simulating pod compromise in Kubernetes environments and testing firewall rule effectiveness under stress conditions. Understand how controlled chaos can lead to deeper system hardening and shift security practices from reactive incident response to proactive vulnerability discovery, ultimately making systems safer through purposeful breaking and testing.
