Binary Authorization is a critical Google Cloud security control that enforces policy-based deployment rules. It mandates that only container images with valid cryptographic attestations (proof of successful vulnerability scanning, code reviews, etc.) can be deployed to GKE or Cloud Run. Use this guide to establish robust supply chain security and compliance controls for your cloud-native applications.

This guide details how to implement Kubernetes Pod Security Standards (PSS) using the Pod Security Admission (PSA) controller. PSS defines three mandatory security levels—Privileged, Baseline, and Restricted—for container workloads. It is essential for enhancing security posture, ensuring compliance, and migrating away from deprecated PodSecurityPolicy (PSP) controls by applying namespace labels and defining compliant pod specifications.

This skill guides the implementation of Mobile Application Management (MAM) policies, enabling robust data protection for corporate assets on both managed and unmanaged mobile devices (BYOD). It covers configuring app-level controls such as Data Loss Prevention (DLP), selective wiping, and containerization using platforms like Microsoft Intune and Azure AD. Use this when enforcing data separation between personal and work environments without requiring full device enrollment.

This guide details how to use Kubernetes NetworkPolicies to enforce granular, pod-level network segmentation. It covers establishing default deny rules, defining specific ingress and egress rules for services, and implementing zero-trust microsegmentation. Use this skill to build robust security architecture and prevent lateral movement within a container cluster.

OPA Gatekeeper is a powerful Kubernetes admission controller that enforces policies using Rego rules. It utilizes ConstraintTemplates and Constraints to validate, mutate, or deny API requests at the cluster admission stage. This tool is essential for implementing policy-as-code practices, ensuring that Kubernetes deployments adhere to organizational security standards, compliance requirements, and best practices, such as mandating labels or blocking privileged containers.

Pod Security Admission (PSA) is a built-in Kubernetes admission controller designed to enforce Pod Security Standards (Baseline, Restricted, Privileged) at the namespace level. It serves as a crucial replacement for the deprecated PodSecurityPolicy (PSP), allowing users to implement robust security controls and maintain compliance. By applying specific labels, administrators can set enforcement modes (enforce, audit, warn) to harden container environments against unauthorized privilege escalation and security risks.

A comprehensive tool for auditing container security posture by detecting potential escape vectors. It analyzes Kubernetes Pod specs for dangerous configurations, such as running in privileged mode, dangerous capability assignments (like CAP_SYS_ADMIN), host namespace sharing, and writable hostPath mounts. Ideal for security assessments and incident response to prevent container breakout.

An open-source tool based on the CIS Docker Benchmark. It systematically audits critical security aspects of Docker deployments, including host configuration, daemon settings, and container runtime. It generates a detailed compliance report (pass/fail/warn) to ensure best practices and security compliance in production environments.

This skill provides a comprehensive guide for deploying Microsoft Defender for Cloud across Azure, multi-cloud, and hybrid environments. It covers activating specific Defender plans for various workloads (servers, containers, storage), optimizing the Secure Score, establishing environment connectors for AWS/GCP, and implementing advanced controls like Just-In-Time (JIT) access for robust, centralized cloud workload protection.

This skill guides the implementation of comprehensive security controls for container registries. It details workflows for vulnerability scanning using Trivy and Grype, generating Software Bill of Materials (SBOMs) with Syft, and enforcing image authenticity using Cosign and Sigstore. It is essential for building robust CI/CD pipelines and preventing supply chain attacks by ensuring only scanned, signed, and compliant images are deployed.

Harbor is an open-source container registry designed for robust security and compliance. This guide details the comprehensive workflow for securing your container ecosystem by implementing advanced features such as vulnerability scanning (Trivy), image signing (Notary/Cosign), Role-Based Access Control (RBAC), and content trust policies. Learn how to enforce image provenance and maintain strict access control in Kubernetes environments.

This guide details how to implement secure, keyless software signing using the Sigstore ecosystem components (Cosign, Fulcio, Rekor). It establishes cryptographic provenance for container images and binaries by binding identity via OIDC, ensuring verifiable integrity and tamper-proofing throughout the CI/CD supply chain.
