Edward Snowden's Revelations, Documented by Laura Poitras, Highlight Insider Threat in National Security
Edward Snowden's 2013 disclosures, reported by journalists including Laura Poitras, revealed extensive surveillance activities by the National Security Agency (NSA), including programs like PRISM. Snowden, an NSA contractor through Booz Allen Hamilton, had legitimate access to classified documents, which he then removed and brought into public view. This event was not a traditional external breach but an 'insider threat,' where an authorized user exploited their access for purposes unintended by the organization. The revelations sparked global debates on surveillance, secrecy, and civil liberties, while internally, they forced national security institutions to re-evaluate their access control and monitoring systems.
