Final answer:
The correct statement is that JIT permissions reduce unauthorized access risk by granting temporary access when necessary, improving security within PAM tools by limiting the exposure time of privileged accounts.
Therefore, the correct answer is: option A).JIT permissions reduce unauthorized access risk by granting temporary access only when necessary.
Step-by-step explanation:
Just-In-Time (JIT) permissions and Privileged Access Management (PAM) tools in the context of IT security is the approach that limits the time window during which privileged accounts are exposed, thus reducing the opportunity for potential attackers to exploit these permissions.
Option A is the correct choice because JIT permissions are indeed designed to provide access only when needed, making them a key component of a robust security strategy within PAM. The temporary nature of JIT permissions is what helps to enhance security in an organization.
Options B, C, and D are incorrect. JIT permissions do not grant permanent access (B); instead, they offer a time-limited access control mechanism. PAM tools are focused on managing privileged (not standard) user permissions (C), and JIT permissions are indeed suitable and recommended for enhancing security in medium-sized companies (D).
