What is the most secure action Janna should take with client files when leaving her desk?

The most secure action Janna should take with client files when leaving her desk is to put the file in a locked desk drawer. This method provides a physical barrier against unauthorized access to sensitive information. By securing the files in a locked drawer, Janna minimizes the risk that someone could accidentally view or misuse the client information in her absence.

Leaving the files open on the desk presents a significant security risk, as anyone passing by could easily access and read private client information. Placing the files in a confidential inbox might offer some level of security, but it is often not as secure as a locked drawer, depending on the overall access to that inbox. Handing the files to a nearby co-worker could be risky as well, unless that co-worker is authorized to view that information, since it may still lead to a breach of confidentiality. Therefore, securing the files in a locked desk drawer is the most prudent action for maintaining client privacy and adhering to professional standards of confidentiality.
