GIME Training

What "GIME Training" Actually Means

When people search for GIME training, they usually mean one of three things: a formal instructor-led or online course, a self-directed lab program, or a structured practice routine built around the exam's published objectives. For the GIAC iOS and macOS Examiner (GIME), all three can coexist, but none of them is mandatory. GIAC does not impose an education, work-hour, or training-hour requirement. If you want the eligibility details, our guide to GIME requirements and prerequisites covers them in full.

What training really needs to accomplish is narrower and more practical than "learn Apple forensics." The exam is a 75-question, 2-hour, open-book test. That means your training has to produce two things at once: genuine analytical skill with macOS and iOS artifacts, and a fast, reliable way to locate details in printed material while the clock runs. Candidates who focus only on the first often discover on exam day that knowing a concept and finding the supporting note in 90 seconds are different skills.

FOR518 and the Official Training Path

The SANS course most closely aligned with this credential is FOR518: Mac and iOS Forensic Analysis and Incident Response. It is the natural training companion to the GIME, and many candidates pair the course with an exam attempt. A few points are worth stating precisely so you plan accurately:

• Course and exam are priced separately. SANS training and affiliate bundles carry their own pricing, distinct from the GIAC attempt fee.
• Course recommendations are not eligibility rules. FOR518 describes working knowledge of forensics and the Unix command line as useful background. That is advice for getting the most out of the class, not a GIME entry requirement.
• Course sections are not the exam objectives. The course is a teaching vehicle; the exam is built from GIAC's published certification objectives. Always map your notes to the objectives, not just the course chapter order.

The Unix command line point deserves emphasis. Apple systems are Unix-derived, and a large share of artifact analysis involves examining plists, databases, and logs from a terminal. If you have never used a shell comfortably, spend time there before or alongside any formal course. It will make nearly every objective easier.

How the Exam Format Shapes Your Training

Training for an open-book proctored exam differs from training for a closed-book memorization test. Here is what the published format implies for how you should prepare.

Several details are not publicly specified: the scored versus unscored item split, the exact mix of question types, and whether any practical component exists beyond standard questions. Do not assume features from other certifications apply. Train for a rigorous knowledge-and-application exam and keep an open mind about item style. For a candid look at how demanding that combination feels, see how hard the GIME exam is, and for the scoring threshold itself, the GIME passing score explained. Note that a passing score is not the same thing as a pass rate; the population pass rate is not publicly specified, which we discuss in what the data shows about GIME pass rates.

Training Plan Across the 13 Objectives

GIAC lists 13 certification objective headings for the GIME. These appear in the issuer's own order and capitalization, and importantly, no official percentage weights are published. That means you cannot rationally skip a heading on the assumption it counts for little. Treat all 13 as fair game, and use the groupings below to organize training. For a deeper breakdown of each heading, read the complete guide to all 13 GIME content areas.

Foundations: Operating Systems and File Systems

Triage, Response, and Configuration

Application, Document, and Cloud Analysis

Advanced Analysis: Logs, Timelines, Memory, and Behavior

Building Your Open-Book Index

Because printed books, notes, and an index are permitted while electronic references and internet access are not, the index is arguably the highest-leverage training artifact you will create. A well-built index turns a stack of paper into a searchable tool; a sloppy one makes it dead weight.

What Belongs in the Index

• Artifact locations: where specific data lives on macOS and iOS, tied to the relevant objective heading.
• Tool and command references: the shell commands and examiner tools you actually used in labs.
• Terminology: short definitions of terms you tend to confuse.
• Where to find it: book, page, and a keyword so you can jump straight to the source.

What Must Stay Out

Materials that resemble practice or exam questions and answers are prohibited. Keep your reference notes explanatory rather than question-shaped. If a page reads like a Q&A drill, leave it at home. Always confirm current rules in the GIAC proctoring guidance before exam day, since policy details can change.

Our GIME cheat sheet offers a compact review of must-know facts that can seed your own index, though your hand-built version will always serve you better because you will remember how you organized it.

Hands-On Lab Work for Apple Forensics

The objectives are practical. Reading about plists and unified logs is not a substitute for opening them. A sensible training lab includes:

• A macOS test environment you can freely explore, generating your own artifacts by installing applications, creating documents, and changing settings, then finding the traces you left.
• Terminal fluency with the commands used to inspect files, parse property lists, and query databases.
• Sample evidence images or exercises from your course, used to practice triage, timeline building, and pattern-of-life reasoning end to end.
• A habit of documentation, writing short notes of what you did and what you found, which doubles as raw material for your index.

A powerful technique is to perform an action yourself, such as saving a document to iCloud or sending a message, then hunt for every artifact it created. That cause-and-effect loop builds the intuition the Pattern of Life and Document and iCloud analysis headings reward.

Sequencing Your Preparation

Generic scheduling advice is less useful than a plan tied to the objectives themselves. The sequence below follows dependency: foundations first, then evidence sources, then synthesis. Adjust the pace to your own experience and the time you have inside your activation window. For a broader strategy discussion, see our GIME study guide for first-attempt success.

The reason timelines and Pattern of Life come late is that they depend on everything before them: you cannot build a trustworthy timeline until you understand the artifacts feeding it. Triage and Incident Response also benefit from being practiced last, once you know what evidence exists and where.

Training, Attempt Fees, and Time Windows

Budgeting for GIME training means separating several distinct costs and clocks. The published figures, excluding applicable sales tax, are below.

No member versus non-member fee schedule is published, and SANS course and affiliate bundle pricing is separate from the figures above. For the full picture, including how bundles interact with attempt purchases, read our GIME certification cost breakdown.

Understanding Your Time Window

Once you activate an attempt, you have a 120-day window to complete it. That window is separate from the 2 hours of examination time. A standard extension adds 45 days, subject to a 570-day maximum access limit. Purchase-specific delivery terms and your GIAC account govern your actual attempt, so verify them rather than assuming. This matters for training because activating too early, before your preparation is nearly complete, burns time you cannot easily recover without paying for an extension.

The exam is taken through onsite Pearson VUE or remote ProctorU, subject to availability for your purchased attempt. For scheduling realities, see GIME exam dates and scheduling.

After Training: Practice, Scheduling, and Renewal

Once your labs and index are in place, shift to simulated testing. A full-length timed run teaches pacing and reveals which objective headings still need work. You can sharpen that phase with the realistic question sets on our GIME practice test site, and use the same site to find weak spots before your activation window closes. Remember that answers cannot be reviewed or changed after submission, so rehearse committing to answers calmly rather than leaving difficult questions for a second pass you will not get.

Credential Lifetime

The credential is valid for 4 years. Renewal is available through 36 CPEs or by passing the renewal exam, with the renewal fee. Additional renewal registrations within 2 years after a full-price $499 renewal are $249 each. Planning for renewal early helps you treat continuing education, such as new Apple forensics research and tooling, as ongoing training rather than a scramble.
