GIAC Security Essentials (GSEC) Certification Training Course
Get ready for the GIAC Security Essentials (GSEC) exam with on-demand, self-paced prep that covers the hands-on defense work GSEC tests, from network architecture and access control to Linux, Windows, cloud and cryptography.
What the GSEC course covers and who it's for.
Accumentum's GSEC prep course is for people moving into security from IT, and for security staff who want a broad, hands-on credential. GIAC says GSEC holders have shown they are qualified for hands-on IT security roles, so most of the course is spent doing the work.
We built the course around GIAC's published GSEC certification objectives. You'll work through networking and protocols, defensible network architecture, endpoint and network security devices, Linux and Windows hardening, cryptography, cloud and virtualization, logging and SIEM, and incident handling. GSEC includes CyberLive hands-on questions, so labs run through the whole course.
Accumentum is an independent training provider. We are not affiliated with, endorsed by or a partner of GIAC or the SANS Institute. GIAC sets the exam rules, fees and scoring, so check giac.org before you register for your attempt.
Get ready for GSEC the way the exam actually tests.
Cover Every GSEC Objective
Work through each certification objective GIAC publishes for GSEC, in an order that builds on itself.
Practice Hands-On
GSEC includes CyberLive questions that run in real virtual machines, so labs are part of every module.
Build an Open-Book Index
GIAC exams are open book. We help you build and test the index you'll bring into the exam.
Know the Exam Before You Sit It
GSEC is 106 questions in 4 hours with a minimum passing score of 72%, per GIAC. We pace practice to match.
Who Should Attend
- IT staff with a networking or systems background who are moving into security.
- Security analysts, administrators and managers who want a broad hands-on credential.
- Operations staff, IT engineers and supervisors.
- Forensic analysts, penetration testers and auditors who need a strong defensive base.
Prerequisites
- There are no Accumentum enrollment prerequisites and GIAC doesn't require any to sit GSEC.
- You'll get more out of the course if you're comfortable with basic networking, the Windows and Linux command line, and core security terms. Security+ or similar experience is a good starting point.
