Zero Trust
Zero Trust is a cybersecurity strategy that assumes no user, device, or application, inside or outside an organization's network, should be trusted by default. It requires strict identity verification for every access attempt, regardless of its origin.

TECHNICAL DEFINITION
Zero Trust is a cybersecurity architecture and security model based on the principle of "never trust, always verify," mandating strict identity authentication and authorization for all users, devices, applications, and workloads accessing network resources, even those internal to the perimeter. This model employs continuous validation, micro-segmentation, and least privilege access to protect critical military and defense assets and data from sophisticated cyber threats.
BACKGROUND
Zero Dark Thirty is a 2012 American political action thriller film directed by Kathryn Bigelow and written by Mark Boal. Produced by Boal, Bigelow, and Megan Ellison, and independently financed by Ellison's Annapurna Pictures, the film dramatizes the nearly decade-long international manhunt for Osama bin Laden, leader of the terrorist network al-Qaeda, after the September 11 attacks, which culminates in the discovery of his compound in Pakistan and the U.S. military raid where bin Laden was killed on May 2, 2011. It stars Jessica Chastain as Maya, a fictional CIA intelligence analyst, with Jason Clarke and Joel Edgerton appearing in supporting roles.
