evaluation

1. Assessment of an information technology (IT) product or system against defined security-related functional and assurance criteria, performed by a combination of testing and analytic techniques.
2. The detailed examination of a system or a product to search for vulnerabilities and to determine the extent to which the required or claimed security functions are upheld by its implementation [CESG].

evaluation assurance level (EAL)

One of seven increasingly rigorous packages of assurance requirements from CC (Common Criteria) Part
3.
Note: Each numbered package represents a point on the CC's predefined assurance scale. An EAL can be considered a level of confidence in the security functions of an IT (information-technology) product or system. [After CC'99]

evaluation baseline

Documentation that formally defines the security functions of a system or product against which its evaluation is performed [CESG].
Note: A System Electronic Information Security Policy forms the basis of the evaluation baseline for a system.

evaluation unit

evaluator actions

A component of the evaluation criteria for a particular phase or aspect of evaluation, identifying what the evaluator must do to check the information supplied by the sponsor of the evaluator, and the additional activities he must perform [ITSEC].

evanescent field

In a waveguide, a time-varying field having an amplitude that decreases monotonically as a function of transverse radial distance from the waveguide, but without an accompanying phase shift.
Note 1: The evanescent field is coupled, i.e., bound, to an electromagnetic wave or mode propagating inside the waveguide.
Note 2: The evanescent field is a surface wave.
Note 3: In fiber… (Read More →)
