Which term defines the levels of assurance, with 1 the lowest and 7 the highest?

• A. Kernel
• B. Evaluation Assurance Level (EAL)
• C. UEFI
• D. SELinux

Answer: (B)

Assurance levels describe how much confidence evaluators have in a product’s security properties. The term that defines these levels, from 1 the lowest to 7 the highest, is Evaluation Assurance Level. They come from the Common Criteria framework, which assesses development processes, design, implementation, and testing. Higher levels require more rigorous evaluation, including thorough documentation and formal verification in some cases, giving buyers a clearer sense of the security confidence they’re getting. The other terms don’t describe these levels: a kernel is the core part of an operating system, UEFI is a firmware interface, and SELinux is a security policy enforcement mechanism.
