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:
- Public domain information sources
- Windows operating systems
- Unix operating systems
- Voice networking
- Wireless networking.
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:
- A multiple-choice written examination
- A hands-on practical examination in two sequential sections, six 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)
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.
