Katie Arrington has been appointed Chief Information Security Officer at the Department of Defense, marking her second appointment to this role under the Trump administration. With previous experience developing the Cybersecurity Maturity Model Certification (CMMC), Arrington is positioned to enhance the cybersecurity protocols within the Defense Industrial Base. Despite her qualifications, she faced security clearance challenges in 2021 when the NSA suspended her clearance following allegations of disclosing classified information, leading to administrative leave and a lawsuit against the DoD.
"Upon information and belief, the NSA's action to allege [Arrington] committed any type of security violation is baseless or exaggerated and normally would not serve as the grounds to immediately suspend an individual's clearance access."
"During his first term, she served as the CISO for the Pentagon's Office of Acquisition and Sustainment, where she helped develop the Cybersecurity Maturity Model Certification (CMMC) for contractors and vendors."
