The DoD Office of Inspector General will begin the subject audit in December 2021. The objective of this audit is to determine whether DoD’s deployment of collaboration tools used to facilitate telework during the coronavirus disease–2019 (COVID-19) pandemic exposed DoD networks and systems to potential malicious activity, and the extent to which the DoD implemented security controls to protect the collaboration tools used on its networks. We will perform this audit in accordance with generally accepted government auditing standards. We may revise the objective as the audit proceeds, and we will consider suggestions from DoD management for additional or revised objectives.
