This skill automates the hardening of Linux endpoints (Ubuntu, RHEL, CentOS) by implementing industry-standard security best practices guided by CIS Benchmarks. It systematically secures various layers, including filesystem permissions, network parameters (sysctl), SSH configuration, user access controls (PAM), and integrates deep auditing using auditd and OpenSCAP. It is essential for achieving compliance with standards like PCI DSS, HIPAA, and SOC 2.

This skill guides the security hardening of Windows endpoints (10/11, Server 2019/2022) using established CIS Benchmarks. It provides a comprehensive workflow for establishing secure organizational baselines, configuring Group Policy Objects (GPOs), and enforcing security controls across critical areas like password policies, audit logs, and firewall rules. It is essential for achieving compliance with standards like PCI DSS, HIPAA, and SOC 2.

This skill guides security analysts through advanced threat-hunting methodologies focused on detecting DNS-based persistence. It analyzes passive DNS history, zone file audits, and API data (like SecurityTrails) to identify unauthorized record modifications, subdomain takeovers, and DNS hijacking attempts that bypass traditional security controls. Ideal for SOC analysts and threat hunters.

Provides a structured methodology for proactive threat hunting against Living-off-the-Land Binaries (LOLBins). It guides practitioners in identifying techniques where adversaries abuse legitimate system tools (like certutil, mshta, rundll32) to execute payloads while bypassing traditional security controls (AV/EDR). Ideal for incident response, red team validation, and improving detection coverage against fileless attacks.

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.

Implements comprehensive security controls for the entire API key lifecycle, including secure generation, hashing, storage, rotation, and revocation. This skill involves designing keys with sufficient entropy, enforcing per-key scoping, setting rate limits, and building automated workflows to prevent leakage and unauthorized access. Essential for robust server-to-server authentication.

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 skill guides the progressive adoption of the CISA Zero Trust Maturity Model (ZTMM) v2.0. It provides a comprehensive, structured roadmap for assessing and improving security architecture across five critical pillars: Identity, Devices, Networks, Applications, and Data. Learn to perform gap analysis and implement advanced controls needed to achieve optimal zero trust compliance.

Implement a comprehensive Cloud Security Posture Management (CSPM) solution across multi-cloud environments (AWS, Azure). This skill guides the use of industry tools like AWS Security Hub, Azure Defender for Cloud, Prowler, and ScoutSuite to continuously detect misconfigurations, compliance violations, and vulnerabilities. It is crucial for establishing robust, centralized security controls and meeting regulatory compliance requirements.

This utility implements comprehensive Cloud Workload Protection (CWPP) by monitoring compute workloads on cloud instances (EC2/GCE). It provides runtime security controls, detecting process anomalies, unauthorized binary execution, cryptomining activity, and suspicious network connections using AWS and Google APIs. Ideal for establishing robust security postures and meeting compliance requirements.

This skill provides comprehensive guidance on implementing robust network security controls in Kubernetes using Calico's CNI capabilities. Learn to define and audit NetworkPolicy and GlobalNetworkPolicy resources to achieve zero-trust microsegmentation, restrict egress traffic, and control all pod-to-pod communications, ensuring compliance and enhanced security posture.
