What does the term "sanitization" of classified information refer to?

The term "sanitization" in the context of classified information specifically refers to the process of removing all classified markings and information to render the material unclassified. This is crucial for ensuring that sensitive or classified information does not remain inadvertently accessible after it is no longer necessary for national security purposes. The sanitization process can involve either physical destruction of documents or redaction of sensitive information while ensuring that no residual classified data can be retrieved.

Sanitization is an essential practice in information security, as it helps maintain the integrity and confidentiality of classified information by preventing unauthorized access or disclosure. By cleaning documents of their classified status, individuals or organizations can safely share or dispose of materials without compromising security protocols.
