What is the GIAC GREM Certification Exam: Everything Explained

Did you know that cybercrime damages are expected to cost the world $10.5 trillion annually by 2025? With such staggering statistics, computer security professionals have become more important than ever, and organizations are seeking skilled and qualified professionals who can protect their systems from potential attacks. 

This is where certifications like the GIAC GREM come into play.

The GIAC (Global Information Assurance Certification) GREM certification is a popular option for those specializing in malware analysis and reverse engineering. Ponemon Institute says data breaches cost $3.86 million. In order to mitigate these threats, organizations need trained professionals in identifying them and minimizing their effects.

The GIAC GREM certification exam is designed to test your knowledge and skills in malware analysis, reverse engineering, and memory forensics. The GREM certification is a challenging exam that requires candidates to understand these concepts deeply. 

However, according to CompTIA, cybersecurity certifications like the GIAC GREM can increase your earning potential and help you advance your career. In fact, CompTIA's research found that individuals who hold computer security certifications earn, on average, 9% more than their non-certified candidates. 

Earning the GIAC GREM certification exam is an excellent way to demonstrate your skills and knowledge and could lead to better career opportunities and a higher salary.

What is the GIAC GREM certification exam?

The GIAC Reverse Engineering Malware (GREM) certification is an industry-recognized certification that validates an individual's skills and knowledge of reverse engineering principles and techniques. The GIAC GREM certification program is designed for technologists (information technology engineers) who protect organizations from malicious code.

GIAC GREM-certified professionals are proficient in reverse-engineering malicious software that targets common platforms, such as Microsoft Windows and web browsers. They are experts in forensic investigations, incident response, and Windows system administration. With the GREM certification, you can showcase your cutting-edge malware analysis skills to your employer or customers.

In order to earn the GIAC GREM certification, you must pass a single exam that tests your skills and knowledge in the following areas:

  • Analysis of malicious document files, analyzing protected executables, and analyzing web-based malware. 
  • In-depth analysis of malicious browser scripts and in-depth analysis of malicious executables.
  • Malware analysis using memory forensics and malware code and behavioral analysis fundamentals.
  • Windows assembly code concepts for reverse-engineering and common Windows malware characteristics in assembly.

The GIAC GREM exam is a 2-3 hour online test with 66-75 multiple-choice questions. To pass the GREM certification exam, candidates must obtain a minimum passing score of 73 percent.

Exam certification objectives and outcome statements

Malware analysis fundamentals

Candidates will be able to identify malware analysis lab needs and describe key methods for analyzing malicious software.

Malware flow control and structures

Candidates can analyze loops and conditionals in assembly language, which are common execution flow control mechanisms.

Overcoming misdirection techniques

Candidates can overcome malware's use of misdirecting execution workflows as an anti-analysis technique.

Reversing functions in assembly

Candidates will be able to understand the use of parameters, return values, and other structures in malware functions written in assembly language.

Static analysis fundamentals

Candidates will be able to analyze the static properties of malware samples and develop theories about their nature and subsequent analysis.

Unpacking and debugging packed malware

Candidates will demonstrate the process for unpacking malware with a debugger and repairing it for further analysis.

Who can take the GREM exam?

The GREM certification is among the most highly regarded certifications in the security industry. With GREM certification, you can demonstrate your knowledge and skills in malware reverse engineering.
