This comprehensive guide details how to implement robust security hardening measures for LDAP directory services. It specifically addresses critical vulnerabilities like LDAP injection, anonymous binding, and channel binding bypass. Key features include mandatory LDAPS enforcement, granular access control list configuration, and integrating advanced monitoring to ensure the infrastructure meets high compliance standards (e.g., NIST 800-53). Essential for security architects and operations teams.

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 guide details the comprehensive deployment of Cisco Duo Multi-Factor Authentication across critical access points like VPN, RDP, SSH, and web applications. It covers setting up the Duo Authentication Proxy, implementing adaptive access policies based on risk and device health, and deploying phishing-resistant methods like WebAuthn/FIDO2, ensuring compliance with NIST standards. Use this when hardening identity access management or establishing robust security controls.

This guide details the robust process of implementing VLAN-based (802.1Q) network segmentation on managed switches. It is crucial for isolating critical zones—such as DMZ, servers, and IoT—to meet strict compliance standards (PCI-DSS, HIPAA) and significantly limiting the blast radius during a security incident by controlling lateral movement. Includes port hardening and ACL configuration.

A comprehensive guide to configuring pfSense firewalls for robust network security. This skill covers setting up complex network segmentation across multiple zones (DMZ, internal, guest, IoT), implementing granular firewall rules, configuring NAT for port forwarding, and establishing site-to-site or remote-access VPN tunnels using IPsec or OpenVPN. Ideal for network engineers deploying perimeter or internal firewalls.

This guide provides a comprehensive walkthrough for deploying, configuring, and tuning Snort 3. It covers essential steps such as setting network interfaces to promiscuous mode, writing custom rules using Lua, integrating with SIEM platforms, and utilizing community rulesets. Ideal for network security professionals implementing robust, signature-based intrusion detection at critical network boundaries.

A comprehensive guide to deploying and configuring Suricata as a high-performance Intrusion Detection System (IDS) or Intrusion Prevention System (IPS). This skill covers setting up multi-threaded packet processing for high-throughput links, enabling protocol-aware inspection (HTTP, TLS, DNS, SMB), generating structured EVE JSON logs for SIEM ingestion, and integrating advanced signature and anomaly detection capabilities.

A comprehensive guide to implementing and validating Transport Layer Security (TLS) 1.3. This skill covers configuring modern cipher suites, key exchange groups, and enforcing perfect forward secrecy (PFS). Use this when deploying secure communication protocols, hardening network services, meeting compliance standards, or performing deep security assessments on web servers and applications.

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 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.

A comprehensive guide on deploying Cloudflare Access and Tunnel to establish a Zero Trust Network Access (ZTNA) solution. This method replaces traditional VPNs by securely exposing self-hosted internal applications (web, SSH, RDP) without opening inbound ports. It integrates identity-aware policies, device posture checks, and robust identity providers (Okta, Azure AD) for highly secure, least-privilege access.
