Using Pod Overhead and Kata Containers to Isolate Kernel Memory and Stop Container Slab Leaks

The article explains how intensive file‑system reads in a Kubernetes pod cause kernel slab memory to balloon, why standard cgroup limits cannot contain the leak, and demonstrates step‑by‑step how configuring Pod Overhead with Kata containers creates a separate sandbox cgroup that isolates kernel memory, preventing host‑level OOM.

How ClawLess Secures Autonomous AI Agents with Formal System‑Call Isolation

The ClawLess framework, developed by researchers from Southern University of Science and Technology and Hong Kong University of Science and Technology, combines formal security policies, physical sandboxing, user‑space kernels and BPF‑based system‑call interception to protect highly autonomous AI agents from rogue behavior and external attacks.

How Docker Uses PID Namespaces to Isolate Containers: A Deep Dive

This article explains Docker’s core isolation mechanisms, focusing on how Cgroups and PID namespaces create separate process spaces, demonstrating with Ubuntu container commands, and clarifying why each container sees its own PID 1 despite the host’s actual process IDs.
