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 by Anchore that inspects container images, filesystems, and SBOMs for known CVEs. It leverages Syft-generated Software Bill of Materials (SBOMs) to match packages against multiple databases including NVD, GitHub Advisories, and OS-specific feeds. It is ideal for security assessments, CI/CD integration, and implementing severity-based build gates.

Integrates Aqua Security's Trivy scanner into CI/CD pipelines to perform automated vulnerability scanning on Docker images and related artifacts. It detects OS package CVEs, application dependency issues, and Dockerfile misconfigurations. This ensures that only secure, compliant images can proceed to registry push or production deployment by enforcing strict quality gates.

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.

A comprehensive guide and toolkit for advanced network reconnaissance using Nmap. It covers sophisticated techniques including service version detection, vulnerability scanning via Nmap Scripting Engine (NSE), firewall evasion methods (e.g., fragmentation, decoy addressing), and structured output parsing for integration into vulnerability management pipelines. Essential for authorized penetration testing.

A comprehensive guide for securing container registries by enforcing vulnerability scanning (Trivy, Grype), generating Software Bill of Materials (SBOM), and implementing digital signing using Cosign and Sigstore. This solution is essential for establishing robust CI/CD pipelines and preventing supply chain attacks before image promotion.

A comprehensive guide to hardening container registries using Harbor. Learn how to enforce strict image provenance and deployment security by integrating vulnerability scanning (Trivy), cryptographic image signing (Cosign/Notary), granular Role-Based Access Control (RBAC), immutable tag policies, and content trust. Essential for environments requiring high compliance and robust supply chain security.
