Which of the following statements is true regarding classified information?

The statement that classified information requires specific handling and dissemination protocols is accurate and reflects the necessary practices for maintaining the security of sensitive information. Classified information is designated with levels of classification (such as Confidential, Secret, and Top Secret) based on the potential impact that its unauthorized disclosure could cause to national security.

Due to the sensitive nature of this information, there are established protocols that govern who can access it, how it must be stored, and how it can be transmitted or shared. These protocols ensure that only those individuals with the appropriate security clearance and a legitimate need to know can access the classified information. This controlled access is critical to prevent unauthorized disclosure and to safeguard national interests.

In comparison, the other statements are misleading. Sharing classified information freely among coworkers is a breach of protocol, as it undermines the necessary safeguards in place. The idea that classified information is always permanent or cannot be reclassified is incorrect, as information can be declassified or reclassified based on changes in relevance or security assessments. Lastly, the classification levels cannot be ignored merely because the information is outdated; the protocols remain in place to protect even older classified information until it is officially declassified.
