ARRINGTON’S ROLE AS CISO
Arrington has been in her role as the CISO for USD/AS since August 2020 and was appointed to the DoD CISO role in January 2019. In this role, she leads the effort to address the cybersecurity of the Defense Supply Chain where she evangelized Supply Chain Risk Management (SCRM) principles designed to enhance the Defense Industrial Base security with her primary focus on the Cybersecurity Maturity Model Certification process. Both topics have been top of mind these last six months as we’ve learned of Solar Winds and other supply chain compromises affecting not only the DIB community, but global organizations including many with infrastructure responsibilities.
In September 2020, the Department issued an interim rule regarding the implementation of the CMMC which received community pushback from industry. Arrington, in her role would have been responsible for the issuance of the interim rule. In November 2020, Arrington gave Congress an update on her CMMC efforts, noting that suppliers need to “register their own assessments in the supplier risk platform.
Speculation is rampant on what it is that Arrington is alleged to have revealed, including tying her to the allegations being made by a television personality that was being targeted by NSA. According to a Tweet from her attorney Zaid, the investigation into Arrington began approximately six weeks ago and is in no way tied to the allegation associated with NSA.
