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.

A comprehensive guide to deploying Palo Alto Networks Next-Generation Firewalls (NGFWs). Covers advanced security techniques like App-ID for application awareness, User-ID for identity mapping, zone-based policy enforcement, SSL decryption, and robust threat prevention profiles. Essential for building enterprise-grade network security architectures.

This guide details how to implement NextDNS as a zero-trust DNS filtering layer. By utilizing encrypted resolution (DoH/DoT) and real-time threat intelligence, it blocks malicious domains, prevents data exfiltration, filters ads/trackers, and enforces granular security policies across all endpoints, aligning with Zero Trust principles and enhancing overall network security.

A comprehensive guide to implementing Zero Trust Network Access (ZTNA) across major cloud platforms (AWS, Azure, GCP). This skill replaces traditional VPNs with identity-aware proxies, micro-segmentation, and conditional access policies. It ensures secure, context-aware access to cloud workloads, limiting lateral movement and adhering to BeyondCorp architectural principles.

This skill guides the end-to-end deployment of Zero Trust Network Access (ZTNA) using Zscaler Private Access (ZPA). It replaces traditional, perimeter-based VPNs by enforcing identity-based, context-aware microsegmentation. Learn to configure Identity Provider integration, deploy App Connectors, define granular application segments, and establish robust access policies for secure, outbound-only connections.

This skill simulates various network attack scenarios, including bandwidth throttling, traffic shaping, and network degradation, using tools like tc, iperf3, and Scapy. It is designed for authorized security assessments to test the resilience of applications, validate Quality-of-Service (QoS) policies, and assess the ability of network monitoring tools to detect sophisticated traffic manipulation attacks (e.g., Slowloris-style attacks).

A comprehensive guide for systematically evaluating Kubernetes cluster security. It simulates advanced attacker techniques against critical components like the API server, etcd, kubelet, RBAC, and network policies, identifying misconfigurations and vulnerabilities. Essential for security auditors, penetration testers, and DevOps teams performing deep cluster security assessments.

A comprehensive guide detailing the use of Tenable Nessus, an industry-leading vulnerability scanner. Learn how to configure advanced scan policies, perform both authenticated and unauthenticated scans across servers, network devices, and web applications. This skill covers end-to-end processes from execution to result analysis and reporting.

This skill provides a comprehensive guide to hardening managed Kubernetes clusters on major cloud platforms (EKS, AKS, GKE). It details implementing critical security layers, including Pod Security Standards, least-privilege network policies, workload identity (eliminating static cloud credentials), and runtime security monitoring. Essential for securing production environments and meeting compliance requirements.

A comprehensive guide on implementing advanced security observability using eBPF and Cilium Tetragon. This skill covers real-time tracking of process execution, network connections, and file system access directly in the kernel. Learn how to author TracingPolicy CRDs, utilize kprobe/tracepoint hooks for in-kernel filtering, and enforce runtime security policies (e.g., process killing) on Linux hosts or Kubernetes clusters.
