Match each physical security control mechanism on the left with its primary protective function or implementation objective on the right.
- Air gapIsolates high-security systems completely from all local and external network connections.
- Security guardProvides real-time human discretion to detect tailgating and challenge suspicious visitors.
- BollardPrevents vehicular impact against physical building perimeters and entrance ways.
- Smart card reader with PIN padRequires multi-factor physical authentication combining a physical token and a knowledge factor before granting access.
Cevap
Air gap matches physical isolation from network connections; Security guard matches providing real-time human discretion against tailgating; Bollard matches preventing vehicular impact; Smart card reader with PIN pad matches multi-factor physical entry authentication.
Air gaps enforce absolute physical network isolation; security guards offer dynamic human judgment to stop tailgating and monitor entry points; bollards physically obstruct vehicle ramming attempts; and smart card readers combined with PIN pads enforce multi-factor authentication (something you have plus something you know) for secure area access.
