When is it permissible to post classified information on social networking services?

Posting classified information on social networking services is permissible only when proper authority has been granted. This means that an individual must have official permission or directive from an authorized entity before sharing any classified material. The protection of classified information is paramount to national security, and there are strict protocols in place to safeguard sensitive data. Consent or approval from a designated authority ensures that such data is shared responsibly and in compliance with relevant regulations.

While there might be situations where declassified information could be shared or an individual's supervisor might have general oversight, such allowances do not extend to classified information. Proper authority encompasses specific knowledge of the information’s classification status and the implications of sharing it, thereby mitigating risks associated with unauthorized disclosure.
