This skill covers end-to-end processes from execution to result analysis and reporting.

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.

This guide provides a deep dive into hardening AWS Identity and Access Management (IAM) configurations. It teaches advanced security practices, including enforcing the principle of least privilege, defining granular policy scopes, implementing permission boundaries, and leveraging Access Analyzer to ensure continuous compliance and minimize the blast radius of security breaches.

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 provides a comprehensive guide for deploying Microsoft Defender for Cloud across Azure, multi-cloud, and hybrid environments. It covers activating specific Defender plans for various workloads (servers, containers, storage), optimizing the Secure Score, establishing environment connectors for AWS/GCP, and implementing advanced controls like Just-In-Time (JIT) access for robust, centralized cloud workload protection.

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 comprehensive guide outlines the end-to-end security lifecycle for Kubernetes applications deployed via Helm. It covers critical topics such as chart provenance verification (GPG signing), template scanning (using tools like kubesec and checkov), enforcing strict security contexts, managing secrets securely (ExternalSecrets), and defining robust RBAC rules for CI/CD pipelines.

This skill provides comprehensive guidance on hardening and securing critical process historian servers (e.g., OSIsoft PI, Honeywell PHD) operating within Operational Technology (OT) environments. It covers best practices for network placement across the Purdue Model, implementing robust access controls, establishing secure data replication architectures through DMZs (using data diodes), preventing SQL injection, and maintaining data integrity for safety-critical and regulatory reporting purposes. It is essential for minimizing cyber risks in industrial control systems.
