This comprehensive guide details advanced network reconnaissance using Nmap's full capabilities. It covers sophisticated host discovery across multiple protocols, deep port scanning with timing and performance tuning, accurate service version enumeration, and OS fingerprinting. Furthermore, it teaches advanced techniques like firewall evasion (fragmentation, spoofing) and running NSE scripts for systematic vulnerability detection, crucial for authorized security assessment reports.

This guide details implementing robust, multi-layered security for public-facing API Gateway endpoints using AWS WAF. Key features include configuring managed rule groups for OWASP Top 10 protection, setting up granular rate limiting to prevent abuse, implementing bot mitigation, and performing IP reputation filtering. Essential for maintaining API integrity and availability.

A comprehensive guide to implementing least-privilege security for AWS Lambda execution roles. It details the process of auditing existing permissions, analyzing actual API usage via CloudTrail and IAM Access Analyzer, creating narrowly scoped IAM policies, and enforcing strict permission boundaries (SCPs) to eliminate over-privileging and minimize the blast radius.

This skill guides the implementation of comprehensive security controls for container registries. It details workflows for vulnerability scanning using Trivy and Grype, generating Software Bill of Materials (SBOMs) with Syft, and enforcing image authenticity using Cosign and Sigstore. It is essential for building robust CI/CD pipelines and preventing supply chain attacks by ensuring only scanned, signed, and compliant images are deployed.

Harbor is an open-source container registry designed for robust security and compliance. This guide details the comprehensive workflow for securing your container ecosystem by implementing advanced features such as vulnerability scanning (Trivy), image signing (Notary/Cosign), Role-Based Access Control (RBAC), and content trust policies. Learn how to enforce image provenance and maintain strict access control in Kubernetes environments.

This skill provides a comprehensive guide to hardening managed Kubernetes clusters on major cloud platforms (EKS, AKS, GKE). It details implementing critical security layers, including Pod Security Standards, least-privilege network policies, workload identity (eliminating static cloud credentials), and runtime security monitoring. Essential for securing production environments and meeting compliance requirements.

A comprehensive guide for systematically assessing REST and GraphQL API endpoints against the OWASP API Security Top 10 risks. This includes practical workflows for testing critical vulnerabilities such as Broken Object Level Authorization (BOLA), broken authentication, excessive data exposure, and rate limiting, using tools like Burp Suite, Postman, and ffuf. Ideal for pre-deployment audits and authorized penetration testing engagements.

A comprehensive guide for assessing the security of JSON Web Token (JWT) implementations. This toolkit details attacks against cryptographic weaknesses, including algorithm confusion (e.g., RS256 to HS256), 'none' attacks, brute-forcing HMAC secrets, and claim manipulation. Ideal for penetration testing and security audits of modern APIs and SSO systems.

This skill provides advanced techniques and code examples for monitoring, mapping, and pivoting across adversary-controlled infrastructure. It leverages Passive DNS, Certificate Transparency logs, Shodan/Censys scanning, and network fingerprinting (JARM/JA3S) to discover C2 servers, phishing domains, and exploitable assets over time, which is crucial for advanced security operations and threat intelligence gathering.

This guide details implementing an IEC 62443 compliant conduit architecture for secure remote access into Operational Technology (OT) environments. It mandates the use of jump servers, MFA gateways, session recording, and approval workflows within a DMZ to strictly control vendor and engineer access, eliminating direct VPN connections to critical ICS assets.

A comprehensive framework for advanced forensic analysis of UEFI firmware and boot process integrity. It details methods to detect firmware implants in SPI flash, audit UEFI variables (PK, KEK, DB), inspect the EFI System Partition (ESP) for unauthorized components, and analyze boot chain anomalies. Ideal for investigating advanced persistent threats (APTs) and verifying system security posture against rootkits and bootkit techniques.

This tool monitors Certificate Transparency (CT) logs to detect unauthorized certificate issuance for owned domains, discover hidden subdomains, and track suspicious certificate activity. By querying public CT logs and APIs (like crt.sh), it helps build continuous security pipelines, identify potential phishing infrastructure, and map the external attack surface for comprehensive threat intelligence.
