This guide details how to harden the Docker daemon (dockerd) configuration by modifying /etc/docker/daemon.json. It implements critical security controls such as user namespace remapping, disabling inter-container communication (ICC), enforcing no-new-privileges, and configuring secure TLS client authentication. Use this method to prevent container breakout, privilege escalation, and lateral movement, ensuring compliance with standards like CIS benchmarks.

This skill guides users through implementing and managing Kubernetes Pod Security Standards (PSS) using the Pod Security Admission (PSA) controller. Learn how to assign security profiles (Privileged, Baseline, Restricted) to namespaces, audit existing workloads for compliance, plan migrations from deprecated PSPs, and adjust securityContext settings to meet high hardening and compliance requirements.

This skill details how to configure and manage the Kubernetes Pod Security Admission (PSA) controller. PSA enforces Pod Security Standards (Privileged, Baseline, Restricted) at the namespace level, replacing the deprecated PodSecurityPolicy. It guides users on setting cluster-wide defaults, applying standards via labels, and utilizing 'enforce', 'audit', or 'warn' modes for robust cluster security and debugging.

This guide outlines best practices for hardening Kubernetes Role-Based Access Control (RBAC). It focuses on implementing least-privilege principles by auditing and removing excessive cluster-admin bindings, scoping roles to namespaces, separating service accounts, and integrating external OIDC providers. Use this when improving cluster security posture, meeting compliance standards, or mitigating privilege escalation risks.

This guide details the operational workflow for namespace-scoped tenants within KubeSphere DevOps. It outlines how users without cluster-admin privileges can securely perform DevOps operations by strictly utilizing KubeSphere's dedicated APIs (`/kapis/`) and authenticating via OAuth tokens, ensuring strict resource isolation and access control within their designated namespace.

A comprehensive guide covering expert techniques for breaking out of container isolation. This playbook details methods for exploiting privileged modes, abusing cgroups, manipulating namespaces, and leveraging vulnerabilities in Docker or Kubernetes environments. Essential for advanced security research and penetration testing.

This skill provides comprehensive operations for managing NodeGroup resources. It allows users to query, create, update, delete, and manage bindings for nodes, namespaces, and workspaces within the edgewize nodegroup environment. Ideal for infrastructure automation, troubleshooting, and API-driven cluster management.

A comprehensive playbook detailing expert techniques to escape multiple types of restricted environments, including Python pyjail, Docker containers, seccomp filters, and browser rendering processes. It covers advanced exploitation vectors like namespace escapes, kernel exploits, and built-in function bypasses for achieving code execution.

A comprehensive tool for aggregating and displaying system metrics (counters, gauges, histograms) from the observability namespace. It computes baselines and flags anomalies by detecting deviations exceeding standard deviations, providing a clear snapshot of system health, error rates, and performance degradation trends.

A specialized deep-dive skill for analyzing container-to-host escape vulnerabilities. This tool is used after a sandbox orchestrator establishes initial assumptions, focusing on mapping isolation boundaries (namespaces, cgroups, seccomp, capabilities). It helps prove boundary crossings, identify minimal exploit primitives, and determine if an exploit can break out of the container context to the host kernel.

This extension provides comprehensive management for external access using the standard Kubernetes Gateway API and Traefik as the underlying proxy. It supports multi-tenant scoping across cluster, workspace, and namespace levels, enabling robust, modern API gateway configuration within the KubeSphere ecosystem.
