Final answer:
Physical Access Control can mitigate the threat of tailgating, as it involves secure mechanisms to prevent unauthorized physical entry. It has a lesser effect on digital threats like pharming, social engineering, and brute-force attacks.
Step-by-step explanation:
The security threat that can be mitigated with Physical Access Control is tailgating. Physical access control systems are designed to restrict unauthorized individuals from entering controlled environments. Tailgating, which is when an unauthorized person follows an authorized person into a restricted area, can be successfully prevented by implementing physical barriers such as turnstiles, electronic locks, and security personnel.
While Physical Access Control might also deter burglary to some extent because it involves unauthorized physical entry, it has a lesser effect on mitigating threats like pharming, social engineering, and brute-force attacks. These are primarily digital threats that require cybersecurity measures. Pharming redirects users to fraudulent websites to collect sensitive data, while social engineering and brute-force attacks are methods used to gain unauthorized access to systems by exploiting human psychology or trying many passwords, respectively.
