Asecurity guardis a human element in physical security, making them susceptible tosocial engineering attacks. Social engineering exploits human behavior, and a guard can be tricked into allowing unauthorized access through persuasion, manipulation, or deception.
* Security guard (Answer A):Human elements are the most vulnerable to social engineering techniques like impersonation or manipulation.
* Access control vestibule (Option B):This is a physical security barrier, which is harder to exploit through social engineering.
* Perimeter fencing (Option C):This is a static physical barrier, not susceptible to social engineering.
* Biometric locks (Option D):These rely on biological data and are not susceptible to social engineering in the same way a human would be.
* Bollards (Option E):Physical barriers that are not vulnerable to social engineering.
