Structures completed intrusion investigations with the Diamond Model by documenting adversaries, capabilities, infrastructure, and victims plus their relationships, metadata, and pivots to cluster incidents and support campaign attribution, confidence scoring, and analytic write-ups.

This guide provides a comprehensive deep dive into implementing advanced network segmentation and zero-trust security controls within Kubernetes clusters using Calico. It covers standard Kubernetes NetworkPolicy, utilizing Calico's GlobalNetworkPolicy, and defining security Tiers, ensuring fine-grained, least-privilege communication between pods, and establishing robust security architectures for compliance.

This guide details the implementation of microsegmentation using Akamai Guardicore, enabling organizations to map complex application dependencies, visualize east-west traffic flows, and enforce least-privilege network policies. It is crucial for achieving zero-trust compliance by preventing lateral movement across heterogeneous workloads in data centers, cloud environments, and Kubernetes clusters.

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.

This skill covers implementing Open Policy Agent (OPA) and Gatekeeper for robust policy-as-code enforcement. Learn to write complex Rego policies, deploy OPA Gatekeeper as a Kubernetes admission controller, and integrate policy evaluation into CI/CD pipelines to enforce security and compliance across clusters.

Implement Kubernetes RBAC to enforce least-privilege access across namespaces, covering Role/ClusterRole design, binding configuration, service account hardening, OIDC integration, and audit logging for multi-tenant clusters.

A comprehensive guide to securing Kubernetes Role-Based Access Control (RBAC). It teaches best practices for implementing least-privilege policies, eliminating excessive cluster-admin bindings, utilizing namespace-scoped roles, and integrating external identity providers (OIDC) to mitigate risks like privilege escalation and unauthorized data access.

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 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 security auditing tool designed to assess a Kubernetes cluster's compliance posture against established CIS benchmarks. It performs deep checks on control plane components (API Server, etcd, Controller Manager), worker nodes, and Role-Based Access Control (RBAC). Use it for proactive security assessments, compliance validation, and hardening throughout the CI/CD lifecycle.

This guide provides a comprehensive methodology for assessing the security posture of Kubernetes etcd clusters. It covers critical areas including encryption at rest (for secrets), TLS transport security, access control validation, secure backup procedures, and network isolation checks, ensuring cluster data integrity and confidentiality.
