The assessment procedures in Special Publication 800-53A may be adapted to address system- and platform-specific or organization-specific dependencies. For example, the assessment of a UNIX implementation of the IA-2 control for identification and authentication of users might include an explicit examination of the .rhosts file for UNIX systems since improper entries in that file can result in bypassing user authentication. Recent test results may also be applicable to the current assessment if those test methods provide a high degree of transparency (e.g., what was tested, when was it tested, how was it tested). Standards-based testing protocols such as SCAP provide an example of how organizations can help achieve this level of transparency. SCAP provides transparency through the use of standardized content that defines testing methods, and through standardized results that indicate what content was used, what system state was tested, what state was found, what tool was used to perform the testing, and when the testing was performed.
