A detailed methodology for proactive threat hunting focused on identifying deep-seated persistence mechanisms within Windows operating systems. This guide covers advanced techniques such as monitoring Run keys, analyzing Winlogon modifications, detecting IFEO injection, and identifying COM object hijacking. It is crucial for incident response, purple teaming, and ensuring system integrity against advanced persistent threats (APTs).

This guide details a threat hunting technique for detecting persistence mechanisms utilizing Windows Registry Run keys (T1547.001). By analyzing Sysmon Event ID 13 logs, it identifies suspicious auto-start entries pointing to temporary directories, encoded PowerShell commands, or abused LOLBins. Essential for SOC analysts and security engineers investigating incidents and developing robust detection rules.

This skill guides threat hunters in detecting MITRE ATT&CK T1098 account manipulation techniques. It focuses on analyzing Windows Security Event Logs (like 4738, 4728) to uncover shadow administration creation, suspicious group membership changes, SID history injection, and unauthorized credential modifications, crucial for incident response and building robust detection rules.

Monitors Windows process creation events to flag Living Off The Land Binary abuse by matching Event ID 4688/Sysmon 1 logs against LOLBAS database entries, supporting threat hunting and SIEM rule creation for fileless attacks.

This skill provides a comprehensive guide on implementing AES-256-GCM, a robust symmetric block cipher, for protecting sensitive data at rest. It covers best practices including secure key derivation (using PBKDF2 and Argon2id), proper management of initialization vectors (IVs) and nonces, and utilizing authenticated encryption to ensure data integrity and detect tampering.

This guide details the implementation of robust API abuse detection mechanisms. It covers advanced rate limiting techniques, such as the Token Bucket and Sliding Window algorithms, to defend APIs against DDoS attacks, brute force attempts, and credential stuffing. It emphasizes using distributed stores like Redis for accurate, scalable, and adaptive security controls in an API gateway context.

This comprehensive guide details how to implement centralized security controls at the API gateway layer. It covers critical functionalities such as JWT authentication enforcement, advanced rate limiting, request/response validation against OpenAPI specs, and integrating Web Application Firewalls (WAF). The process is applicable across major platforms like Kong, AWS API Gateway, and Azure APIM, ensuring robust defense in depth for microservices architecture.

This skill covers implementing robust API rate limiting and throttling controls using advanced algorithms like token bucket and sliding window. It teaches how to protect backend systems against attacks such as brute force, credential stuffing, and resource exhaustion. Key components include configuring limits per user, per IP, and per endpoint, utilizing Redis for distributed counting, and implementing proper HTTP 429 responses for effective abuse prevention.

This guide details how to implement robust API schema validation using OpenAPI Specification (OAS) and JSON Schema. It enforces strict input/output contracts, preventing critical vulnerabilities such as injection attacks (SQLi, XSS), data leakage, and mass assignment by validating data types and structure at the API gateway or development level.

This guide details how to implement comprehensive API security testing using the 42Crunch platform. It performs static audits of OpenAPI specifications (API Audit) and dynamic vulnerability scanning (Conformance Scan) against live APIs. Supports integration into CI/CD pipelines to proactively discover OWASP API Top 10 vulnerabilities, enabling a Shift-Left security approach.

This guide details how to implement multi-layered API threat protection using Google Apigee. It covers critical security policies including JSON/XML content validation, OAuth 2.0 enforcement, SpikeArrest rate limiting, and advanced regex patterns to defend against OWASP Top 10 threats. Ideal for establishing robust API security controls and meeting compliance requirements.

This guide details the implementation of Microsoft Entra Privileged Identity Management (PIM), enforcing Just-in-Time (JIT) role activation, mandatory approval workflows, and periodic access reviews for critical Azure AD and resource roles. It aligns with Zero Trust principles by eliminating standing privileges.
