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
