The Department of Homeland Security's Science and Technology (DHS S&T) directorate has released two online resources as part of efforts to help the public mitigate GPS spoofing incidents.

DHS said Friday it seeks to assist users in checking the GPS data's integrity through the Epsilon Algorithm Suite and the Position, Navigation and Timing (PNT) Integrity Library.

Epsilon AS algorithms are designed to equip end users with spoofing detection capacities without the need to modify GPS receivers while PNT Library is a software tool that works to provide various levels of data security.

"Since GPS signals can be jammed or spoofed, critical infrastructure systems should not be designed with the assumption that GPS data will always be available or will always be accurate," said Jim Platt, chief of strategic initiatives at the Cybersecurity and Information Security Agency's (CISA) National Risk Management Center.

Platt added DHS advises the public to devise a holistic defense approach that focuses on the integrity of GPS data from its receipt to its implementation into a platform.

NASA has selected researchers that will take part in initial studies focused on technologies for lunar missions including optical systems and “levitation” technology based on autonomous concepts.

NASA said Friday that the agency’s Space Technology Mission Directorate (STMD) will provide $125,000 in grants to each of the 16 participants for Phase I of the NASA Innovative Advanced Concepts (NIAC) program.

The participants will conduct feasibility studies throughout a nine-month perood and will be eligible to apply for Phase II grants if the projects are deemed successful.

NASA will provide $500,000 for each Phase II grantee to cover a two-month concept development period. Phase III involve contracts worth up to $2 million for two-year maturation activities.

Jenn Gustetic, director of early-stage innovations and partnerships at STMD, said that providing seed funding for initial research “could benefit NASA greatly in the long run."

Selected proposals cover a range of topics such as deployable space-based structures, lunar tracks for transporting cargo on the lunar surface and a “light bender” concept for generating power on the moon.

The National Security Agency (NSA) has released a guidance on the zero-trust model for network security and said that systems leveraging the concept are better positioned to address threats but implementing the framework entails careful planning.

NSA said in its report that while the data-centric model for cybersecurity results in comprehensive monitoring, transitioning to such systems could provide risks of weakened security postures.

According to the guidance, adopting a mindset focused on zero trust requires an understanding of the modern threat landscape as well as a coordinated system for monitoring and management.

Other requirements include assuming malicious intent in networks, assuming risks for compromise in all devices, accepting the risky nature of access approvals and ensuring preparedness in conducting rapid damage analysis and recovery functions. 

NSA also cites persistent adherence to a zero-trust mindset as a key requirement for implementing the concept.

“Administrators and defenders may become fatigued with constantly applying default-deny security policies and always assuming a breach is occurring, but if the Zero Trust approach falters, then its cybersecurity benefits become significantly degraded or eliminated,” the report states.

The U.S. Army is conducting a demonstration activity to assess four air vehicles that may serve as potential successors to the service branch's RQ-7 Shadow fleet.

Various brigade combat teams within the Army Forces Command underwent a six-week flight training activity to familiarize themselves with the air vehicles, the service branch said Friday.

The Army can transport each air vehicle via CH-47 Chinook helicopters or organic ground vehicles in a move to enable tactical maneuverability. FORSCOM's Future Vertical Lift cross-functional team has worked with the Army's Program Executive Office since 2018 to select and obtain drone units for the project.

The team held soldier touch points to secure inputs and feedback in line with the effort. The event is slated to run through March 5th.

The Department of Defense (DOD) has created a modernization strategy for hypersonics to update the nation’s strike missile arsenal, DOD News reported Saturday.

Mike White, principal director for hypersonics at the office of the undersecretary of defense for Research and Engineering, said at an Air Force Association symposium that the strategy includes developing strike weapons for inland, coastal and maritime targets and establishing a layered defense architecture to defeat adversarial hypersonic weapons.

The strategy also entails deploying reusable hypersonic weapons for intelligence, surveillance and reconnaissance (ISR) missions as well as strike operations and space access.

White said the Pentagon expects to deploy strike capabilities through the mid-2020's and a layered hypersonic defense infrastructure through the late 2020s. The DOD seeks to implement a reusable weapon by the early 2030's, according to White.

White’s comments come after the U.S. Air Force launched an effort to develop the AGM-183A weapon for rapid airborne response.

Brig. Gen. Heath Collins, program executive officer for weapons and director of the Air Force Life Cycle Management Center's armament directorate, said his office will conduct the first flight test for the hypersonic weapon's boosters.

"We're really proud to be in the hypersonics weapon enterprise at this point in this exciting time, and we're just on the cusp of an operational capability," he said.
