How should a URL be marked on a webpage to ensure it remains operable?

The correct marking of a URL on a webpage is crucial to maintain its operability while also ensuring that it complies with the necessary classification guidelines. When a URL is portion marked, it allows for the specific classification of the information contained within it while keeping the functional integrity of the URL intact. This enables users to access the link as intended, even when classification markings are applied.

Portion marking involves designating specific parts of the information, which, in this case, applies to the classified aspects of the URL without hindering its overall usability. It demonstrates a balance between security requirements and functionality, thus ensuring that the information remains accessible for operational purposes. This practice is essential in maintaining transparency and effective communication while adhering to the protocols of handling classified information.
