Recommended Study Timeline

Plan for approximately 10-16 weeks of dedicated study. Here is a suggested weekly breakdown:

• Week 1: Topic area 1: Planning & scoping (Rules of engagement, legal considerations, methodologies)
• Week 2: Topic area 2: Reconnaissance (OSINT, DNS recon, Google dorking, Shodan, attack surface mapping)
• Week 3: Topic area 3: Scanning (Nmap advanced techniques, host discovery, service enumeration)
• Week 4: Topic area 3: Enumeration (SMB, SNMP, web apps, vulnerability scanning, network mapping)
• Week 5: Topic area 4: Exploitation (Metasploit, buffer overflows, service exploitation)
• Week 6: Topic area 4: Web exploitation (SQL injection, XSS, authentication bypass, web shells)
• Week 7: Topic area 4: Password & wireless (Brute force, hash cracking, WPA attacks, client-side)
• Week 8: Topic area 5: Post-exploitation (Windows/Linux privilege escalation techniques)
• Week 9: Topic area 5: Pivoting (Lateral movement, port forwarding, tunneling, AD attacks)
• Week 10: Topic area 6: Reporting (Report writing, risk ratings, remediation recommendations)
• Week 11: Index Building: Create open-book index for exam day, organize notes by topic
• Week 12: Full Review: Practice exams, Index refinement, Weak areas, Exam logistics

Top Study Tips

1. Start with the official exam objectives. Download them from the GIAC website and use them as your study checklist. Every exam question maps to a specific objective.

1. Use active recall over passive reading. Instead of re-reading notes, test yourself with practice questions after each study session. This dramatically improves retention.

1. Start with your weakest topic areas. Score yourself on practice questions after each session, then spend the most time where you miss the most.

1. Build hands-on experience. Set up a lab environment and practice the skills you are studying. Hands-on experience is especially valuable for performance-based questions.

1. Take practice exams under real conditions. Time yourself, eliminate distractions, and simulate the exam environment. Review every wrong answer and understand why it was wrong.
