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.

A comprehensive guide for deploying and managing network deception systems using industry-leading honeypot platforms like OpenCanary, T-Pot, and Cowrie. This skill helps security professionals detect unauthorized access attempts, trace lateral movement, and gather critical threat intelligence by simulating vulnerable services within a controlled environment. Ideal for enhancing network security architecture and creating early warning indicators for intrusions.

This guide details the deployment and configuration of Suricata as a high-performance, inline Intrusion Prevention System (IPS). It covers setting up NFQueue mode, writing custom detection rules, managing commercial and community rulesets (like Emerging Threats), and optimizing performance for active, real-time blocking of malicious network traffic. Essential for robust security architecture and compliance.

This tool analyzes historical network traffic baselines to design secure and functional segmentation architectures for Operational Technology (OT) environments. It helps map flat Purdue-model networks into secure zones (VLANs) and automatically generates required firewall rules based on observed legitimate communication paths, adhering to standards like IEC 62443. Ideal for IT/OT convergence and risk mitigation.

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.

This skill guides the end-to-end deployment and configuration of Palo Alto Networks NGFWs. It covers advanced security features such as App-ID for application-aware policies, User-ID for identity-based enforcement, zone-based architecture, and Content-ID for deep threat inspection. Ideal for migrating legacy port-based firewalls to modern, identity-aware network security architectures.

This guide details the deployment and usage of OPA Gatekeeper, a powerful Kubernetes admission controller. Gatekeeper enforces custom policies written in Rego using ConstraintTemplates and Constraints. It validates, mutates, or denies resource requests at admission time, ensuring that non-compliant workloads are blocked before scheduling. Ideal for organizations requiring robust, code-based policy enforcement to meet strict security and compliance standards.

A Python-powered engine implementing structured OT incident response procedures based on the SANS PICERL lifecycle. It classifies incident severity (safety, process, access, recon) and coordinates cross-functional teams (IT SOC, OT Engineering, Operations) to manage critical threats like ransomware in ICS/SCADA environments. Essential for establishing robust safety protocols and ensuring compliance with IEC 62443 and NERC CIP standards.

This skill details the deployment of Privileged Access Management (PAM) for critical database systems, including Oracle, SQL Server, PostgreSQL, and MySQL. It covers essential security controls such as session proxy configuration, credential vaulting, query auditing, and enforcing least-privilege access, helping organizations meet stringent compliance and security standards.

This guide details the implementation of advanced, phishing-resistant, passwordless authentication using Microsoft Entra ID. It covers configuring FIDO2 security keys, Windows Hello for Business, and passkey support via Microsoft Authenticator. Use this skill to eliminate reliance on passwords, mitigate credential stuffing attacks, and satisfy strict regulatory mandates for modern identity access management.

Implement robust, phishing-resistant authentication using FIDO2/WebAuthn standards. This guide covers integrating WebAuthn APIs, configuring FIDO2 servers, managing passkey enrollment, and migrating systems away from traditional passwords. Essential for meeting high-assurance security standards like NIST SP 800-63B AAL3.
