Episode 54 — Control egress to reduce exfiltration paths and limit command-and-control reachability

This episode explains why outbound traffic control matters in cloud environments and how it changes attacker economics by making exfiltration and command-and-control harder and noisier. You’ll define egress control as limiting where systems can send data, then connect it to exam scenarios involving data loss prevention, containment, and segmentation effectiveness. We’ll cover practical approaches such as restricting outbound destinations, forcing traffic through controlled inspection points, and applying different egress rules for high-risk workloads versus general-purpose systems. You’ll also explore troubleshooting realities like breaking software updates, dependency downloads, and third-party APIs, and how to solve those issues without reverting to “allow all.” By the end, you’ll be able to design egress with a clear balance: enough freedom for business function, but enough constraint to reduce attacker paths and improve detection signal quality.
