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.

A comprehensive guide to configuring secure OAuth 2.0 authorization flows, covering best practices for Authorization Code with PKCE, Client Credentials, and Device Authorization Grant. Learn how to implement mandatory security controls, manage token lifecycles, and align with OAuth 2.1 standards to build robust identity and access management systems.

A comprehensive guide detailing how to implement Zero Trust Network Access (ZTNA) using Zscaler Private Access (ZPA). This process replaces traditional VPNs by deploying App Connectors, defining precise application segments, and establishing granular access policies. Access is strictly controlled based on user identity, group membership, and device posture (health check), ensuring that users only reach authorized resources without needing network-level connectivity.

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.

A comprehensive guide for implementing enterprise-grade Security Access Service Edge (SASE) architectures using Palo Alto Networks Prisma Access. This skill covers configuring ZTNA connectors, GlobalProtect agents, security policies, and device posture checks (HIP) to provide unified, cloud-delivered security, replacing traditional VPNs and maintaining zero trust principles across remote and branch offices.

This guide details deploying Tailscale (or self-hosted Headscale) to create a WireGuard-based zero trust mesh VPN. It establishes encrypted peer-to-peer connections between devices, eliminating the need for traditional VPN servers. Features include identity-aware Access Control Lists (ACLs), subnet routing, and secure connectivity for compliance-driven architectures. Use this when enforcing granular, identity-authenticated access control.

This guide provides comprehensive techniques for detecting Layer 2 ARP poisoning and spoofing attacks. It covers monitoring gratuitous ARP floods, tracking IP-to-MAC mapping changes, and identifying rogue devices. Techniques include deploying ARPWatch, configuring Dynamic ARP Inspection (DAI) on managed switches, and using advanced Wireshark filters or custom Python scripts for robust security monitoring and incident response.

This guide details methods for detecting and mitigating OAuth token theft and replay attacks in cloud environments, specifically targeting Microsoft Entra ID (Azure AD). It covers protection against access token theft, Primary Refresh Token (PRT) abuse, and pass-the-cookie attacks. Users can leverage Conditional Access and Token Protection features to cryptographically bind tokens to devices, significantly enhancing cloud identity security and preventing session hijacking.

A comprehensive guide to implementing Google's BeyondCorp zero trust access model. This solution enforces identity- and device-aware access control using Cloud IAP and Access Context Manager, effectively replacing traditional VPN infrastructure. Use this to secure remote and hybrid access to GCP-hosted or on-prem applications by requiring granular device posture checks and strong user authentication.

This skill implements the CISA Zero Trust Maturity Model (ZTMM) v2.0. It provides a structured framework to assess, gap-analyze, and roadmap the adoption of zero trust architecture across five core pillars: Identity, Devices, Networks, Applications, and Data. It guides organizations from Traditional to Optimal maturity, aiding compliance with NIST standards and federal mandates.

Configure Microsoft Entra ID (Azure AD) Conditional Access policies to enforce zero trust access control. This skill covers critical areas such as signal-based policy design, device compliance requirements, risk-based authentication, named locations, and session controls, aligning with NIST SP 1800-35. Essential for deploying, hardening, or assessing robust Azure AD security architecture.

This guide details how to implement robust device posture assessment within a Zero Trust Architecture (ZTA). It integrates endpoint health signals from major platforms like CrowdStrike ZTA, Microsoft Intune, and Jamf into conditional access policies. Use this to enforce strict compliance checks (e.g., encryption, patch levels) before granting access to critical corporate resources, significantly hardening the security perimeter.
