The GIAC Security Essentials (GSEC) certification is designed for practitioners in information security, validating their knowledge beyond basic concepts. This certification is often described as “a mile wide” so the scope certainly matches that.

Key Information:

  • Exam Format: The certification exam is a proctored test with 106-180 questions to be completed in 4-5 hours. A minimum passing score of 73% is required.
  • Areas Covered:
    • Defense in depth, access control, and password management
    • Cryptography: basic concepts, algorithms, deployment, and application
    • Cloud: AWS fundamentals, Microsoft cloud
    • Defensible network architecture, networking and protocols, and network security
    • Incident handling and response, data loss prevention, mobile device security, vulnerability scanning, and penetration testing
    • Linux: Fundamentals, hardening, and securing
    • SIEM, critical controls, and exploit mitigation
    • Web communication security, virtualization and cloud security, and endpoint security
    • Windows: Access controls, automation, auditing, forensics, security infrastructure, and services
  • Target Audience: GSEC is suitable for new InfoSec professionals with backgrounds in information systems and networking, security professionals, managers, operations personnel, IT engineers and supervisors, security administrators, forensic analysts, penetration testers, and auditors.
  • Delivery: Certification attempts are web-based and require proctoring, with options for remote proctoring through ProctorU and onsite proctoring through PearsonVUE. Attempts are activated in the GIAC account post-approval, and candidates have 120 days from activation to complete the exam.
  • CyberLive: GIAC offers CyberLive, a hands-on, real-world practical testing environment, allowing practitioners to validate knowledge and skills using actual programs, code, and virtual machines.

Invaluable Certification (In My Opinion) (2022)

Difficulty: 3 out of 5.

This course really hammers down on the fundamentals of cyber security: principle of least privilege, defense-in-depth, etc. There's not a whole lot of in-depth talk, but as a way for anyone to be able to take the course and get a very broad understanding of cybersecurity, it's great.

GSEC (2018)

Difficulty: 2 out of 5.

I took this a month after earning CompTIA Security+ and while GSEC was a bit broader and deeper, I could have easily passed it without much studying or indexing. Excellent course overall and I enjoyed it very much, but nowhere near enough value added to justify the difference in cost. Never pay thousands of dollars for a 400-level (basic skill) course when you can get most of the same training for hundreds...
