Guides implementing Kubernetes NetworkPolicy, RBAC, PodSecurityPolicy, Pod Security Standards, and OPA Gatekeeper constraints to enforce defense-in-depth across clusters, covering multi-tenant protection, admission control, and Istio service mesh policies.

Detects and prevents privilege escalation in Kubernetes pods by combining admission control, runtime monitoring, and audit log analysis. Covers security contexts, Linux capabilities, and syscall patterns. Use when investigating pods running as root or privileged, hardening workloads against in-pod escalation, or hunting for containers exceeding their intended scope.

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.

A comprehensive guide detailing how to implement portable Kubernetes NetworkPolicies to enforce zero-trust microsegmentation. Learn to apply default-deny rules, control ingress and egress traffic, and restrict lateral movement between pods and namespaces across various CNI platforms (Calico, Cilium). Ideal for establishing robust security posture and meeting 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 tool audits Kubernetes pod configurations to detect potential container escape misconfigurations. It checks for dangerous settings like privileged flags, excessive capabilities, host path mounts, shared namespaces, and cgroup abuses. Use it for comprehensive security assessments, compliance checking, or generating pre-enforcement security posture reports.

This comprehensive guide details best practices for securing Helm chart deployments within Kubernetes. It covers critical security measures including verifying chart signatures and provenance, scanning templates for configuration misconfigurations, enforcing Pod Security Contexts via values.yaml, managing sensitive data using external secret stores, and scoping RBAC roles for CI/CD pipelines. Essential for maintaining supply chain integrity and meeting compliance standards.

This skill guides the hardening of managed Kubernetes clusters (EKS, AKS, GKE) by implementing critical cloud security best practices. It covers enforcing Pod Security Standards, deploying Network Policies for least privilege communication, and configuring Workload Identity to eliminate static cloud credentials. Ideal for production deployments or remediation after a security audit.

This guide provides implementation patterns for secure integration with the Podium API using REST API calls. It focuses on establishing robust connections with OAuth2 authentication for managing core business functions, including messaging, retrieving customer reviews, and processing payments. It also details essential error handling strategies.

A comprehensive playbook detailing advanced techniques for attacking Kubernetes clusters. Covers API server access, RBAC privilege escalation, service account token abuse, etcd secrets extraction, Kubelet exploitation, and various container escapes. This guide is essential for security professionals and red teams performing deep security assessments on cloud-native infrastructure.

Exploits privileged pods, host mounts, runC CVEs, and exposed Docker sockets to break out of a container and reach the underlying host during an authorized container-security assessment. Use when executing an approved breakout test, demonstrating the real impact of a privileged or hostPath workload, or validating that escape mitigations actually hold. Keywords: container breakout, privileged, hostPath, docker.sock, runC CVE-2019-5736, CVE-2024-21626, release_agent, nsenter. Do not use for defensive detection of these techniques - use detecting-container-escape-attempts.

A comprehensive guide detailing systematic techniques for breaking out of container isolation (Docker, Podman, containerd) into the underlying host operating system. Covers exploiting misconfigurations, abusing privileged modes, manipulating Linux capabilities (CAP_SYS_ADMIN), utilizing namespaces (nsenter), and exploiting known container runtimes CVEs. Essential for penetration testing and security red teaming engagements.
