When should a password combination be changed?

Changing a password combination when individuals with knowledge no longer need access is vital for maintaining security. This practice minimizes the risk of unauthorized access to sensitive information or systems. If someone who previously had access, such as a former employee, still has knowledge of passwords, they could potentially exploit that access even after they are no longer associated with the organization.

Regularly updating passwords in response to changes in personnel helps ensure that only authorized users can access secure data. This is particularly important in environments where sensitive information is handled; it acts as a safeguard against insider threats and reinforces the overall integrity of the security posture.

While there may be policies suggesting regular updates or when a user wishes to change their password, the most critical situation is when access changes due to personnel transitions. This ensures that privileges are current and aligned with the current user roles and responsibilities.
