When an employee departs from a company, what action should be taken regarding their network access account?

When an employee leaves a company, it's crucial to manage their network access account appropriately to protect the organization's information security. Disabling the account is the correct action because it ensures that the former employee can no longer access the company's systems, data, or resources. This step helps prevent unauthorized access, which could lead to data breaches, information theft, or malicious activities.

Disabling the account is usually a temporary action that can be reversed if necessary (e.g., if the employee returns). However, simply terminating the account may not immediately revoke access, and archiving the account does not effectively prevent potential security risks during the transition period. Enabling the account would allow the former employee to maintain access, which poses a significant security risk. Thus, disabling the account balances security with the potential need for future access in a controlled manner.
