Container Runtime Security: seccomp, AppArmor & eBPF LSM

18 minutes

Blocking zero-day exploits in container runtimes means layering seccomp, AppArmor, and eBPF LSM hooks — and knowing exactly where each one fits in the kernel's enforcement chain.

You'll learn:

How seccomp profiles restrict syscall surfaces and which calls are most dangerous to leave open in container workloads

Writing and applying AppArmor profiles to constrain file, network, and capability access at the container level

Where eBPF LSM hooks sit relative to seccomp and AppArmor — and why stacking them closes gaps neither covers alone

Common misconfigurations that leave runtime defenses bypassable even when all three are nominally enabled

How to audit enforcement gaps using tools like bpftrace, strace, and amicontained

Keywords: container runtime security, seccomp profiles Kubernetes, AppArmor containers, eBPF LSM hooks, zero-day exploit prevention
