Which office is typically responsible for enforcing proper marking protocols for classified information?

The agency's security office is responsible for enforcing proper marking protocols for classified information because this office is specifically tasked with handling the security aspects of classified material. The security office ensures that all personnel receive training on the appropriate handling and marking of classified information, adhering to guidelines set by government regulations and agency policies. This includes ensuring that information is marked correctly to indicate its classification level, which is vital for maintaining national security and preventing unauthorized access or disclosure.

Other offices, such as the accounting office, legal department, and human resources office, have different primary functions that do not focus on the security requirements and marking protocols associated with classified information. Their involvement may be related to administrative processes or compliance, but they do not typically oversee the specific security and marking responsibilities that fall under the jurisdiction of the security office.
