Final answer:
Discovering problems with a user's account can be done through multifactor authentication, account review, logging, and enforcing a policy requiring strong authentication. Each method provides distinct security benefits that can help in uncovering and preventing unauthorized access or other account-related issues.
Step-by-step explanation:
Discovering issues with a user's account can be achieved through various methods, each providing a different layer of security and oversight. Multifactor authentication (MFA) is a security system that requires more than one method of authentication from independent categories of credentials to verify the user's identity for a login or other transaction. This could uncover problems if unauthorized access is attempted, as the attacker might fail to provide the required authentication factors.
Account review is a process where the security team periodically examines user accounts for any irregularities, such as inappropriate access rights or unusual activity, which could reveal issues within the account. Logging is integral to security as it records events that occur within the system; reviewing logs could highlight unauthorized access or other account abnormalities.
Finally, a policy requiring strong authentication, which enforces the use of robust passwords and possibly additional security measures like MFA, can prevent many common account problems by making it harder for attackers to gain access in the first place.
