What is a valid reason for classifying information?

Classifying information primarily serves the purpose of protecting national security. This means that certain details must be kept confidential to prevent threats to the safety and interests of the nation. By classifying sensitive information, organizations can ensure that only authorized personnel have access, thereby safeguarding against espionage and unauthorized disclosure that could potentially harm national interests.

While restricting access to information and maintaining organizational secrecy are by-products of classification, they are not the primary justification for the classification process itself. The intent behind classification is deeply rooted in the overarching need to defend national security. Similarly, reducing administrative workload does not align with the fundamental purpose of classification, as the classification process often requires additional oversight and management rather than reducing workload.
