Skill UI

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.

Use RESTler to automate stateful security testing of REST APIs. It processes OpenAPI specifications to generate fuzzing grammars, allowing users to discover complex bugs, such as injection vulnerabilities, resource leaks, and unhandled exceptions (500 errors), by executing diverse sequences of API calls. Essential for robust CI/CD regression testing and proactive API security assessments.

Utilizes ScoutSuite, an open-source multi-cloud auditing tool, to perform comprehensive, agentless security posture assessments across AWS accounts. It queries various AWS APIs to enumerate all resources, identify misconfigurations (such as publicly exposed S3 buckets or weak IAM policies), and generate detailed, actionable HTML reports for compliance and security auditing.

An open-source tool based on the CIS Docker Benchmark. It systematically audits critical security aspects of Docker deployments, including host configuration, daemon settings, and container runtime. It generates a detailed compliance report (pass/fail/warn) to ensure best practices and security compliance in production environments.

This comprehensive guide outlines the end-to-end workflow for mobile device forensics, covering data acquisition and analysis for both iOS and Android platforms. It details techniques using commercial tools like Cellebrite UFED and open-source utilities (ALEAPP, iLEAPP, ADB). This methodology is critical for investigating deleted messages, call logs, location data, and application artifacts in legal or corporate investigations.

Open Source Intelligence (OSINT) is the critical first phase of red team engagements. This guide details how to systematically collect publicly available data about a target organization. It covers mapping network assets (domains, IPs), identifying personnel for social engineering, discovering credential leaks, and mapping the entire technology stack. Use this skill during authorized security assessments to build comprehensive attack surface maps and initial access strategies.
