Why might an administrator utilize Just-in-Time access for VMs?

To allow always-on access for emergency situations
To minimize exposure to attacks
To increase the complexity of the VM setup
To enable unrestricted access to all users

The correct answer is: To minimize exposure to attacks

Just-in-Time (JIT) access is a security feature designed to minimize the exposure of resources, including virtual machines (VMs), to potential attacks. By providing temporary, on-demand access to VMs, JIT reduces the possibility of unauthorized access and limits the time frame in which users have access to critical systems. This approach not only helps protect against threats by ensuring that access is only granted when necessary but also minimizes the attack surface by keeping systems secure during periods of inactivity. While always-on access might seem beneficial in emergency situations, it does not align with the principles of JIT access, which emphasizes granting access only when needed. Increasing complexity in VM setups does not serve the core purpose of enhancing security through timely access control. Finally, enabling unrestricted access is contrary to the essence of JIT, which is predicated on controlled and temporary access to safeguard resources against potential vulnerabilities and threats.
