This skill provides a comprehensive guide to implementing microsegmentation policies. It details how to move beyond traditional network boundaries (VLANs) to enforce least-privilege access control between individual workloads using identity and application context. Essential for preventing lateral movement and establishing a robust zero-trust architecture aligned with industry compliance standards.

This skill guides the implementation and auditing of advanced network segmentation within Kubernetes using Calico. It enables establishing zero-trust microsegmentation by creating and managing NetworkPolicy and GlobalNetworkPolicy resources. Use this to strictly control pod-to-pod traffic, enforce namespace isolation, restrict egress rules, and apply DNS-based security policies, significantly hardening your cluster's security posture.

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.

A comprehensive guide to implementing Kubernetes NetworkPolicies, which enforce granular ingress and egress rules at the pod level. This skill enables zero-trust microsegmentation by defining default-deny rules, allowing specific traffic flows (like DNS or inter-service communication), and blocking sensitive access (e.g., cloud metadata). Essential for securing containerized workloads and preventing lateral movement within a cluster.

This skill covers the comprehensive design and implementation of network segmentation using layered security controls. It details how to establish isolated security zones (e.g., DMZ, PCI CDE, Management) using VLANs, firewall zones, and granular ACLs. The techniques advance from traditional Layer 2 VLAN separation to modern Layer 7 microsegmentation, enforcing zero-trust principles and meeting strict compliance standards like PCI DSS and HIPAA.
