The best practice for physical security in typical multiple‑choice questions is: report suspicious activity and prevent unauthorized access (for example, by not letting strangers “tailgate” through secure doors).

Quick Scoop

What “best practice” usually looks like

In cyber/physical security training, the correct option is usually the one that:

  • Encourages reporting suspicious activity to security or management.
  • Emphasizes controlling access : only let people in if they are clearly authorized, and challenge or refuse entry to unknown individuals.

Typical wrong options in these questions include:

  • Posting access rosters or badge lists in public view.
  • Hiding or not wearing your badge so it can’t be checked.
  • Automatically holding the door for anyone behind you, even if you do not know them.

Everyday examples of good physical security

  • Prevent tailgating : do not allow someone to slip in behind you through a locked door without badging in.
  • Lock doors and secure devices when away from your desk or sensitive areas.
  • Protect visible information : keep screens and printed documents with sensitive data out of public view; shred them when no longer needed.

If your question shows several options, pick the one that focuses on reporting suspicious behavior or properly controlling and verifying access , and avoid anything that exposes access details publicly or relaxes door/badge controls.

TL;DR: The best practice is to control access (no tailgating), wear and use your badge properly, and promptly report any suspicious activity or security concerns.
