The GIAC Penetration Tester (GPEN) certification validates your hands-on ability to conduct successful penetration tests and ethical hacking engagements. This performance-based certification is designed for security professionals who need to expertly simulate real-world attacks to identify and exploit vulnerabilities in an organization's defenses, going beyond automated scanning to demonstrate actual risk.

The GPEN curriculum, derived from the SANS SEC560 course, emphasizes the methodologies and tools used by professional penetration testers. It focuses on a thorough and repeatable process, ensuring you can not only find weaknesses but also effectively communicate findings to help organizations improve their security posture. Certification holders prove they can conduct assessments that are both technically deep and ethically sound.

Key technical domains and practical skills covered include:

• Penetration Testing Methodologies: Conducting structured tests using a documented and repeatable process.

• Exploitation Techniques: Manually writing and executing exploits to compromise systems and applications.

• Advanced Reconnaissance: Conducting thorough passive and active reconnaissance to map attack surfaces.

• Password Attacks & Cracking: Executing various password attacks and leveraging tools to crack hashes.

• Moving Laterally and Persistence: Techniques for pivoting through a network and maintaining access.

• Web Application Penetration Testing: Identifying and exploiting common web app vulnerabilities like SQL injection and XSS.

• Writing Comprehensive Reports: Documenting technical findings into clear, actionable reports for management and technical staff.
