What it asks for. Define and enforce clear desk rules for papers and removable storage media, and clear screen rules for information processing facilities.
In practice. Sensitive papers and media are locked away when not in use and at the end of the day, printers use secure release, and whiteboards are wiped after meetings. Screens lock automatically after a short idle period and staff lock them manually when leaving, with privacy filters for those working in public places. Rules cover home and hybrid working as well as the office. Evidence includes the policy, technical configuration for screen locking and results of periodic walk-throughs.
Common gaps. Automatic screen lock settings are often set too long or not applied to every device type. Clear desk checks, where they happen, ignore home offices and shared spaces, and abandoned printouts remain common.
