A comprehensive guide simulating real-world attacks against internet-facing infrastructure (firewalls, web servers, DNS, etc.). It covers the entire penetration testing lifecycle, including passive and active reconnaissance, vulnerability scanning (using tools like Nmap, Nessus, and Nuclei), manual validation, and simulated exploitation, adhering to standards like PTES and OSSTMM.

A comprehensive solution for performing Operational Technology (OT) vulnerability assessments using the Claroty xDome platform. It automatically discovers assets, correlates vulnerabilities using CVE and ICS-CERT advisories, and calculates risk scores. This method is designed for compliance requirements (e.g., IEC 62443, NERC CIP) and initial asset risk profiling, relying on passive monitoring and safe querying rather than active scanning or penetration testing.

This tool orchestrates safe vulnerability assessments for Operational Technology (OT) and Industrial Control Systems (ICS) environments. It prioritizes safety by guiding users through passive monitoring, native protocol querying, and carefully controlled active scanning methods, specifically designed to identify vulnerabilities without risk of disrupting industrial processes or crashing legacy controllers. Essential for compliance audits (e.g., IEC 62443).

This comprehensive guide details how to perform thorough and passive subdomain enumeration using Subfinder. It is an essential process during the reconnaissance phase of penetration testing, bug bounty hunting, and security assessments. By integrating multiple passive sources (like Shodan, Censys, and Certificate Transparency logs), users can efficiently map the entire attack surface of a target organization, discover forgotten or misconfigured assets, and prepare for subsequent vulnerability scanning.

This comprehensive guide details the process of performing authenticated and unauthenticated vulnerability assessments using Tenable Nessus. It covers everything from advanced scan configuration (port discovery, credentialing, plugin setup) to detailed result analysis, including cross-referencing CVEs and prioritizing remediation based on CVSS scores and exploit availability. Ideal for compliance auditing, penetration testing, and maintaining system patch compliance.

Nikto is a powerful, open-source web server and web application scanner designed for comprehensive vulnerability assessment. It tests over 7,000 potentially dangerous files and checks for critical issues like XSS, SQL injection, outdated versions, and misconfigurations across modern web applications. Ideal for security audit, penetration testing, and validating web server security controls.

Grype is an open-source vulnerability scanner from Anchore. It inspects container images, filesystems, and SBOMs for known CVEs. It leverages Syft-generated SBOMs to match packages against multiple vulnerability databases (NVD, GitHub Advisories). Use it for security assessments, auditing, and integrating into CI/CD pipelines to enforce vulnerability standards and manage supply chain risks.

Use Trivy to automate comprehensive vulnerability detection (CVEs, misconfigurations) in Docker container images within CI/CD pipelines. This skill guides users on establishing robust quality gates—such as integrating into GitHub Actions or GitLab CI—to ensure that only secure images are pushed to production registries, covering OS packages, dependencies, and Dockerfile best practices.

Trivy is a comprehensive open-source vulnerability scanner used for detecting vulnerabilities, misconfigurations, secrets, and license violations across OS packages, language dependencies, and container images. It integrates seamlessly into CI/CD pipelines for robust security testing and compliance.

A comprehensive guide detailing the use of Tenable Nessus, an industry-leading vulnerability scanner. Learn how to configure advanced scan policies, perform both authenticated and unauthenticated scans across servers, network devices, and web applications. 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 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.
