Final answer:
Special Access Programs differ from other classified programs by having stricter access protocols and safeguarding highly sensitive information with enhanced security measures.
Step-by-step explanation:
A key difference between Special Access Programs (SAPs) and other classified programs lies in the strict protocols SAPs have regarding access to information. SAPs are designed to control access, distribution, and protection of particularly sensitive information beyond the measures applied to other classified information. The restricted nature of SAPs ensures that access is granted only on a need-to-know basis and often to a smaller group of individuals. This is done to enhance security and limit the risk of unauthorized disclosure or compromise of the information.
