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.

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.

This skill provides comprehensive guidance and PowerShell scripts for hardening Windows endpoints using Microsoft Defender for Endpoint (MDE). It covers advanced features like Attack Surface Reduction (ASR) rules to block common attack techniques, Controlled Folder Access for ransomware protection, and Network Protection. Use this for deploying enterprise-grade, compliance-required security policies via Intune or Group Policy.

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.

This skill provides a comprehensive guide to deploying a Software-Defined Perimeter (SDP) compliant with the CSA v2.0 specification. It details implementing core zero trust mechanisms, including Single Packet Authorization (SPA) and mutual TLS (mTLS), using a controller and gateway architecture. Use this when establishing invisible, identity-centric network access (dark cloud) to harden infrastructure, enforce strict zero trust policies, or meet advanced compliance requirements.

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 skill details methods and SIEM rules to detect API enumeration attacks, including BOLA and IDOR. It identifies patterns such as sequential ID iteration, parameter tampering, and mixed authorization failure responses (401/403). Use this guide for threat hunting, security incident investigation, and hardening API access control monitoring.

This guide details comprehensive detection methods for DCSync attacks (MITRE T1003.006) in Active Directory. Attackers abuse legitimate directory replication protocols to extract sensitive password hashes. Detection relies on auditing Windows Event ID 4662 for unauthorized access attempts to critical Directory Service GUIDs, specifically flagging non-domain-controller accounts attempting replication calls. Essential for threat hunting and incident response.

This skill provides a comprehensive framework to detect and prevent privilege escalation within Kubernetes pods. It merges preventative measures using admission controllers (like OPA Gatekeeper or Pod Security Admission) to enforce security policies, with runtime monitoring using tools like Falco. It detects dangerous capabilities, unauthorized host access, and suspicious syscall patterns, making it crucial for hardening K8s security posture.

This script automates the detection and exploitation of Broken Function Level Authorization (BFLA) in APIs, following OWASP API Top 10 guidelines. It simulates low-privilege users attempting to access or modify restricted administrative endpoints (e.g., user management, system settings) using techniques like role switching, path manipulation, and parameter tampering. Essential for assessing vertical privilege escalation risks and verifying robust Role-Based Access Control (RBAC).

This guide provides a comprehensive methodology for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities in web applications and APIs. It teaches testers how to systematically manipulate object identifiers (such as numerical IDs, UUIDs, or slugs) within API requests and URLs. Techniques involve using advanced tools like Burp Suite's Authorize extension to test object-level access control, validating both horizontal (same privilege) and vertical (different privilege) access restrictions during authorized penetration tests or bug bounty engagements.
