This skill provides comprehensive guidance on implementing robust network security controls in Kubernetes using Calico's CNI capabilities. Learn to define and audit NetworkPolicy and GlobalNetworkPolicy resources to achieve zero-trust microsegmentation, restrict egress traffic, and control all pod-to-pod communications, ensuring compliance and enhanced security posture.

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 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.

Tetragon, a CNCF project under Cilium, provides advanced, kernel-level runtime security observability and policy enforcement in Kubernetes clusters. By utilizing eBPF, it monitors process execution, file access, and network connections with minimal overhead, enabling detection and prevention of container escapes, unauthorized access, and suspicious activity.

This skill automates the entire phishing incident response lifecycle using the Splunk SOAR REST API. It processes reported emails, extracts indicators of compromise (IOCs) like URLs and IPs, creates incident containers, attaches artifacts, and triggers automated playbooks for deep analysis and reporting. It is essential for security operations teams needing robust, programmatic incident handling and compliance alignment.

In-toto is a CNCF standard project used to verify the integrity of software supply chains. It generates cryptographically signed attestations (link metadata) at every stage of the CI/CD pipeline, proving exactly what artifacts were produced and who authorized the process. This is crucial for securing container builds and ensuring compliance against tampering.

This skill covers performing comprehensive vulnerability assessments across diverse environments, including on-premises infrastructure, cloud VMs, and container registries. It leverages standard network protocols like SSH (Linux) and WMI (Windows), coupled with advanced cloud provider APIs for analyzing disk snapshots without requiring local endpoint agents. Ideal for security auditing and compliance checks.

This skill guides users on performing deep runtime threat detection and forensics in cloud-native environments using Falco. It leverages Falco YAML rules to monitor syscalls, detecting critical security events such as shell spawning, file tampering (e.g., /etc/shadow), network anomalies, and privilege escalation within containers and Kubernetes clusters. Ideal for incident response, security auditing, and validating container runtime security controls.

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.
