Report Description:
What We Looked At
Part of the Federal Aviation Administration's (FAA) efforts to modernize and increase the efficiency of the Nation's aging air traffic system, Data Communications (DataComm) will play an important role in air traffic controller to flight crew communication. Thus, it is critical that FAA incorporate sufficient controls to protect against potential security threats to that communication, including an effective contingency plan to ensure a quick recovery from losses of DataComm availability. Accordingly, we initiated this audit to determine whether (1) FAA is identifying and properly mitigating security risks and (2) FAA's contingency plan is sufficient to limit the effects of DataComm availability losses. We focused on two DataComm systems during our review--the Data Communications Network Service (DCNS) and Tower Data Link Services (TDLS).
What We Found
FAA is identifying--but is not mitigating--security risks in a timely manner. Specifically, two high-impact plans of action and milestones (POA&M) were scheduled to be completed in October 2017. However, as of May 10, 2018, FAA had not mitigated the two security control vulnerabilities. An Agency official stated that FAA is working with a vendor to complete the first POA&M by December 31, 2018, and the second POA&M by March 31, 2019. FAA's contingency plans for DCNS and TDLS are sufficient to limit the effects of DataComm unavailability.

Our Recommendation
FAA concurred with our one recommendation to improve DataComm security controls.
