Zero trust architecture (ZTA) is a cybersecurity approach based on continual verification of each user, device, application, and transaction to protect critical systems and data. NASA has made progress implementing ZTA across its corporate systems (managed by the Office of the Chief Information Officer). However, by delaying ZTA implementation of non-corporate (mission and Jet Propulsion Laboratory) systems, the Agency is missing an opportunity to address enterprise-wide issues that will impact ZTA adoption within the non-corporate environment.

An Amtrak ticket/accounting representative based in Greensboro, North Carolina, was terminated from employment on March 27, 2025, following an administrative hearing. Our investigation found that the former employee violated company policy by allowing an unknown and un-ticketed individual to proceed to the train platform and put an unidentified package onto the train without knowing its contents. The package was subsequently found to contain illegal narcotics. The former employee is not eligible for rehire.
