DoD IG: Military networks are exposed to ‘unnecessary’ cyber risks
By: Mark Pomerleau
The military services are exposing networks to “unnecessary cybersecurity risks” thanks in part to a lack of visibility over software application inventories, according to a Department of Defense Inspector General report.
The IG investigated whether DoD components rationalized their software applications by identifying and eliminating any duplicative or obsolete applications. Rationalizing software applications seeks to improve enterprise IT by identifying all software applications on the network; determining if existing applications are needed, duplicative or obsolete; and determining if applications already existing within the network prior to purchasing new ones.
The audit — which focused on Marine Corps, Navy and Air Force commands and divisions — found that the groups examined did not consistently perform this rationalization process. By not having visibility into software application inventories, these organizations were unable to identify the extent of existing vulnerabilities within their applications, the report found.
Moreover, such a process could lead to cost savings associated with eliminating duplicative and obsolete applications.
Fleet Forces Command was the only command the IG reviewed that had a process in place for eliminating duplicative or obsolete applications. The Air Force did not have a process in place to prevent duplication when purchasing new applications.
The report placed blame on the DoD chief information officer for not implementing a solution for software rationalization in response to Federal Information Technology Acquisition Reform Act requirements.
The IG made three recommendations for the CIO, who did not provide a response to draft recommendations:
- Develop an enterprisewide process for conduction software application rationalization throughout DoD;
- Establish guidance requiring DoD components to conduct rationalization and require DoD component CIOs to develop implementation guidance outlining responsibilities for rationalization. Such a policy should also require components on at least an annual basis to validate the accuracy of their owned and in use software applications inventory; and
- Conduct periodic review to ensure components are regularly validating the accuracy of their inventory and they are eliminating duplicative and obsolete applications.

The next GPS payload will be fully digital
By: Nathan Strout The navigation payload for the next iteration of GPS satellites has passed its critical design review, contractor L3Harris announced Feb. 11. According to the company, which is designing and building the system, the new payload will provide a more powerful, reliable and flexible GPS signal than previous satellites.The GPS IIIF satellites will follow the first 10 GPS III satellites—the first of which is already on orbit and operational. The Air Force plans to eventually build 22 GPS IIIF satellites. While the GPS III satellites use a 70 percent digital Mission Data Unit, the one in the new GPS IIIF payload will be fully digital. According to L3Harris, the new system will “provide more powerful signals and ensure flawless atomic clock operations.” “The digital payload is flexible enough to adapt to advances in GPS technology and future warfighter mission needs,” said Ed Zoiss, president of L3Harris' space and airborne systems. “Proceeding to the next stage in the GPS IIIF navigation payload development process moves the program closer to supporting evolving Air Force mission requirements.” With the critical design review complete, L3Harris can move forward with final development, test and delivery. The company has contributed navigation technology to every GPS satellite in orbit. While L3Harris is designing the navigation payload, Lockheed Martin is the prime contractor for GPS IIIF. The Air Force awarded Lockheed Martin more than $1.3 billion to build the first two GPS IIIF satellites in 2018. Critical design review for the platform is expected in March 2020, according to Space Force budget documents released Feb. 10. Once that is complete and the program passes Milestone C in the third quarter of FY2020, the Space Force will begin procuring additional GPS IIIF satellites with annual contract options. Delivery of the first GPS IIIF satellite is expected in 2026. Among their advanced features, GPS IIIF satellites will boast regional military protection capabilities, which allow them to deliver regionally-limited high-power M-Code signals. It will also include new laser retro-reflector arrays that can provide on orbit position determination. Furthermore, the GPS IIIF satellites are being designed to potentially incorporate technology from Navigation Technology Satellite 3, an Air Force Research Laboratory space vehicle that will be used to test a variety of position, navigation and timing technologies. L3 Harris is the prime contractor on that program, which recently passed its preliminary design review. https://www.c4isrnet.com/battlefield-tech/space/2020/02/12/the-next-gps-payload-will-be-fully-digital/
