03.04.07E Testing, Validation, and Documentation of Changes

Statement

Test, validate, and document changes to the system before finalizing the implementation of the changes.

Guidance

Changes to systems include modifications to hardware, software, or firmware components and defined configuration settings. Organizations ensure that testing does not interfere with system operations that support organizational missions and business functions. Individuals or groups that conduct the tests understand the system security policies and procedures associated with the specific facilities or processes. Operational systems may need to be taken offline or replicated to the extent feasible before testing can be conducted. If systems must be taken offline for testing, the tests are scheduled to occur during planned system outages whenever possible. If the testing cannot be conducted on operational systems, organizations employ compensating protection measures. This requirement enhances SP 800-171 requirement 03.04.03.

Statement

• (includes preempt) Ensure that the threat event does not have an impact.

  • Reduce likelihood of occurrence and/or reduce likelihood of impact.

  • The adversary’s efforts or resources cannot be applied or are wasted.

• (includes exert) Make it more difficult for threat events to cause adverse impacts or consequences.

  • Reduce likelihood of impact and reduce level of impact.

  • Adversary activities are restricted in scope, fail to achieve full effect, do not take place in accordance with adversary timeline, or require greater resources than adversary had planned.

Assessment objective

changes to the system are tested before finalizing the implementation of the changes.

Assessment objective
