What action can make an organization's network susceptible to inappropriate usage incidents?

Disabling authentication for file sharing significantly increases the risk of inappropriate usage incidents within an organization's network. When authentication is disabled, any user on the network—whether authorized or unauthorized—can access shared files without any verification of their identity. This lack of identification creates an open door for potential misuse, where malicious actors can easily enter, exfiltrate sensitive data, or cause damage without being detected.

In contrast, strong authentication measures, regular updates to security protocols, and strict monitoring of user access are all fundamental practices that enhance network security and help prevent incidents of inappropriate usage. These actions are designed to control and track who has access to what data, thereby reducing the likelihood of unauthorized access and potential security breaches.
