(NIST 800-84: Section 6.4) i. The locations for tests vary based on the type of test being conducted and the test’s scope. ii. During a test, the mission of the organization should not be disrupted to the extent that the organization can no longer function and provide the services that it was created to provide. If there is any sign of a possible catastrophic disruption, or the safety of an individual is at stake or the security of the organization or its data is in question, the test director and any other member of the test staff should have the ability to terminate the test immediately. iii. After the test concludes, the test director should conduct an informal test debrief, requesting feedback from everyone present. Coordinate with IRS IT organization or BOD POCs at the end of the test to ensure that test deactivation procedures are completed. Review and evaluate the completed Test Case Template, worksheets, findings, corrective actions, and all test evidentiary documentation. Comments from the debrief, documented observations made by the exercise staff, and recommendations made during the DR test, should be captured in an after action report. Managers may need to be briefed on DR test results.
