In the context of classified information, what is a 'spill'?

A 'spill' refers to the unauthorized disclosure of classified information, particularly to individuals or entities that do not have the appropriate clearance or need to know. The term is most often used in reference to information being disclosed to the public or media, which aligns with the definition of deliberate unauthorized disclosure to outside sources. This kind of event can pose significant risks to national security, as it may lead to sensitive information becoming accessible to foreign adversaries or the general public.

In the context of the other options: accidental disclosure to trusted personnel does not align with the definition of a spill since it involves an unintentional error, rather than a deliberate act. Internal sharing without clearance is also different; while it pertains to unauthorized access, it lacks the broader implications of public disclosure and impacts that characterize a spill. Lastly, the loss of classified material may indicate a security breach, but it is not classified as a spill unless the information is specifically leaked or disclosed outside of controlled channels.
