Final answer:
All visitors to a secure facility should be authorized, vetted, escorted, and monitored to ensure the security and safety of the facility.
Step-by-step explanation:
All visitors to a secure facility should be authorized. They need to have permission or clearance to enter the facility.
However, before visitors are authorized, they are typically vetted. This means that their backgrounds and credentials are checked to ensure they are trustworthy and pose no threat to the facility.
In addition to being authorized and vetted, visitors to a secure facility may also be escorted during their visit. This means that they are accompanied by a staff member or security personnel who ensures they follow the appropriate protocols and do not access restricted areas.
While visitors are in the facility, they may also be monitored to ensure their activities are in line with the facility's security policies and to maintain safety.
