The CREST Certified Infrastructure Tester examination is a rigorous assessment of the candidate’s ability to assess a network for flaws and vulnerabilities at the network and operating system layer.  The exam includes:

Examination format
The format is the same for both the Infrastructure and Application Certified Tester exams.  The candidate will be expected to possess not only the technical ability to find security weaknesses and vulnerabilities, but also the skills to ensure findings are presented in a clear, concise and understandable manner.  The examination consists of three tasks:

To pass the exam, the candidate must pass all sections.  The written elements of the examination are delivered at Pearson Vue test centres;  the practical element is delivered at a CREST examination centre.  Candidates must hold a valid pass in the written element of this examination in order to sit the practical element.

With effect from 1 April 2019, the structure of the practical component is changing.  From this date, it will be split into two sequential sections and be five hours in duration.  The first component will comprise a Scenario question demarcated from the practical component and designed to mimic the skills required to perform a build review and author a client report on the findings.  The second component will be a practical test (now referred to as an Assault Course).

Please be assured that there has been no change to the standard required nor the syllabus content;  the change is merely structural and includes the requirement to write a written report (Scenario) rather than answer a number of shorter, long-form style questions.
