This skill guides the implementation and auditing of advanced container network policies using Calico's specialized CRDs (like GlobalNetworkPolicy and NetworkSet). It enables granular traffic control, zero-trust architectures, and advanced egress filtering based on domain names, which are critical for maintaining strict compliance and isolating workloads across multiple namespaces.

This guide details how to implement robust device posture assessment within a Zero Trust Architecture (ZTA). It integrates endpoint health signals from major platforms like CrowdStrike ZTA, Microsoft Intune, and Jamf into conditional access policies. Use this to enforce strict compliance checks (e.g., encryption, patch levels) before granting access to critical corporate resources, significantly hardening the security perimeter.

This guide details the implementation of GCP Binary Authorization, a crucial deploy-time security control. It ensures that only trusted, verified container images are deployed on GKE or Cloud Run by requiring cryptographic attestations. Learn how to set up KMS-backed attestors, configure policies, and integrate the validation process into your CI/CD pipeline to enforce robust supply chain integrity.

This guide teaches how to implement and audit Google Cloud Platform (GCP) VPC firewall rules using gcloud. It covers creating restrictive ingress and egress rules, enforcing network segmentation using tags and service accounts, and auditing for overly permissive settings. Ideal for compliance, zero-trust architectures, and responding to security findings.

This guide details how to implement HashiCorp Vault's dynamic secrets engine. It automates the generation, lease management, and rotation of short-lived credentials for databases (e.g., PostgreSQL, MySQL), AWS IAM, and PKI certificates. This method eliminates the use of static, hardcoded secrets, enforcing zero-trust principles and meeting stringent compliance mandates like PCI-DSS.

This skill guides the implementation of continuous, risk-adaptive identity verification crucial for Zero Trust Architecture (ZTA). It covers deploying phishing-resistant MFA (FIDO2/WebAuthn), advanced risk-based conditional access policies, and identity governance strategies. Users learn how to move beyond traditional credentials by leveraging multiple signals—such as device posture, behavioral biometrics, and location context—to dynamically assess and enforce trust levels before granting access.

This skill guides the implementation of Just-In-Time (JIT) access provisioning, eliminating standing privileges by granting temporary, time-bound access. It covers designing robust approval workflows, integrating with PAM/IGA systems, automating revocation, and adhering to Zero Trust principles, significantly reducing the attack surface.

This skill guides the implementation of fine-grained network security policies in Kubernetes using Calico CNI. It covers establishing a default-deny baseline, understanding policy ordering, and applying advanced rules like service-account-based selectors. Use it for hardening cluster security, enforcing zero-trust models, and managing network segmentation within containerized environments.

This guide details implementing microsegmentation using Akamai Guardicore Segmentation. It helps map application dependencies, visualize east-west traffic flows, and establish granular, least-privilege network policies across diverse environments (VMs, containers, bare metal, cloud). Essential for achieving zero-trust architecture and meeting compliance standards like PCI DSS or HIPAA by preventing lateral movement.

This guide details the configuration and implementation of mutual TLS (mTLS) authentication between microservices. It utilizes Python's cryptography library for robust certificate generation, validation, and secure service-to-service authentication, essential for adopting zero-trust security models.

A comprehensive guide detailing the implementation of 802.1X port-based Network Access Control (NAC) using RADIUS authentication and platforms like PacketFence. This solution enforces identity-based access, performs endpoint posture assessment, and dynamically assigns VLANs. It is essential for establishing zero-trust networks, meeting stringent compliance standards (PCI-DSS, HIPAA), and automating the onboarding of BYOD devices.

This guide details the deployment of Cisco Identity Services Engine (ISE) for comprehensive Network Access Control (NAC). It utilizes 802.1X authentication, MAC Authentication Bypass (MAB), and posture assessment to enforce security policies. Key features include integrating with Active Directory, assigning dynamic VLANs, and applying TrustSec Security Group Tags (SGTs) for advanced network segmentation in enterprise environments.
