Common Questions

Do I really need a visitor log for a small office?
If the office is part of your FCI environment, yes. Level 1 asks you to escort and monitor visitors, keep a log of physical access, and control access devices such as keys and badges. For a small supplier a simple sign-in log and an escort practice usually satisfy the intent.
