The Myth of Universal VPN Security
Common belief that any VPN provides equal protection ignores implementation differences, transparency, and real-world effectiveness. Reality shows VPNs hide IP …
Sandboxing Autonomous AI Coding Agents: Ephemeral Containers and Egress Boundary Enforcement
Infrastructure security engineer Alex Chen discusses container sandboxing, system call filtering with seccomp and Landlock, and network egress boundaries for au…
Cache Invalidation via Surrogate Keys: Edge Architecture and Purge Mechanics
Decouple cache invalidation from URL paths using Surrogate-Key headers for targeted CDN purging.
Autonomous Vulnerability Discovery: Replacing Static SAST with Adversarial Verifiers
Static code scanners drown engineering teams in unverified alerts. Autonomous security harnesses now combine deterministic coverage ledgers with adversarial ver…
