This guide details the process of configuring microsegmentation policies to enforce least-privilege access between workloads. It covers the entire workflow, from application dependency mapping and discovery (Phase 1) to defining label-based, default-deny security zones (Phase 2). It is crucial for preventing lateral movement in highly secure, zero-trust architectures using tools like VMware NSX, Illumio, and Calico.

A comprehensive guide for deploying Cisco Duo Multi-Factor Authentication across diverse enterprise access points, including VPN, RDP, SSH, and web applications. This skill details advanced security practices, covering adaptive access policies, phishing-resistant authentication (WebAuthn/FIDO2), device health checks, and establishing robust identity and access management controls aligned with industry compliance standards.

This comprehensive guide details the architecture and implementation of VLAN-based network segmentation on managed switches. It teaches professionals how to isolate different network zones (e.g., corporate, DMZ, IoT) to enforce strong access controls, reduce the attack surface, and meet compliance standards like PCI-DSS. The workflow includes designing the VLAN plan, configuring trunking, hardening switches against VLAN hopping, and setting up inter-VLAN routing with ACLs.

Provides a comprehensive guide to configuring pfSense firewall rules, NAT policies, and VPN tunnels. It details best practices for enforcing network segmentation (DMZ, LAN, Guest, IOT), controlling traffic flow, and protecting internal network zones in SMB and enterprise environments. Covers VLAN setup, DHCP/DNS management, and granular access control.

Provides a comprehensive guide on installing, configuring, and tuning the Snort 3 Intrusion Detection System. This skill covers setting up network interfaces for promiscuous monitoring, writing custom rulesets, optimizing detection coverage, and integrating alerts with SIEM platforms to monitor network boundaries for malicious activity.

A comprehensive guide to deploying and configuring Suricata, a high-performance IDS/IPS. This skill covers setting up multi-threaded packet capture, integrating Emerging Threats rulesets, generating structured EVE JSON logs, and enabling deep protocol inspection (HTTP, TLS, DNS). It enables real-time threat detection and seamless SIEM integration for centralized security monitoring.

This skill guides the advanced configuration of Windows Event Logging using Group Policy Objects (GPO) and advanced audit policies. It enables high-fidelity logging for critical security events, including process creation (Event 4688), logon/logoff activities, and object access. The process covers optimizing log sizes and implementing Windows Event Forwarding (WEF) to centralize data into SIEM platforms for effective threat detection and forensic investigation.

This guide details the process of implementing Zscaler Private Access (ZPA) to replace legacy VPNs with a modern Zero Trust Network Access (ZTNA) framework. It covers deploying App Connectors, defining application segments, and establishing granular access policies based on user identity, organizational user groups, and detailed device posture checks (e.g., compliance, anti-malware status).

This comprehensive guide provides a structured, multi-stage workflow for containing active security breaches. It details both short-term and long-term strategies, including network segmentation, endpoint isolation, credential revocation, and evidence preservation. Use this process during confirmed intrusions, ransomware attacks, or lateral movement events to effectively stop adversary activity and secure critical assets before eradication.

This skill guides SOC analysts and detection engineers on how to correlate complex, multi-stage attacks within the IBM QRadar SIEM platform. It covers advanced usage of AQL (Ariel Query Language) for deep event investigation, building custom correlation rules (Building Blocks and Offenses), and cross-source data correlation (e.g., auth failures with network flows). It is essential for reducing false positives and improving threat detection accuracy.

This comprehensive guide details how to implement a Zero Trust Network Access (ZTNA) solution using Cloudflare Access and Cloudflare Tunnel. It provides a secure alternative to traditional VPNs by offering identity-aware, policy-driven access to self-hosted and private applications. The process covers setting up tunnels, integrating major Identity Providers (Okta, Azure AD), and enforcing granular access policies.

A comprehensive guide for deploying and configuring CrowdStrike Falcon EDR agents across diverse endpoints (Windows, macOS, Linux). This skill covers silent installation via SCCM, Intune, GPO, and command-line methods, alongside establishing robust prevention and response policies. Ideal for onboarding endpoints, enhancing threat detection capabilities, and integrating Falcon telemetry into SIEM platforms for advanced security operations.
