How is the security posture of remote access accounts improved?

Improving the security posture of remote access accounts involves a proactive approach to account management and monitoring. Disabling unused accounts is a critical practice because it reduces the number of potential entry points for unauthorized users. When accounts are not actively in use, they pose a risk that could be exploited by attackers.

Monitoring active accounts further enhances security by allowing organizations to detect any suspicious or unauthorized activity in real-time. This includes tracking login attempts, usage patterns, and any unusual behaviors that may suggest a compromise. Together, disabling unused accounts and diligently monitoring those that remain active can significantly lower the risk of unauthorized access and help ensure that only legitimate users have access to sensitive resources.

Other options do not effectively enhance security. Allowing unrestricted access can lead to severe vulnerabilities, especially in remote access scenarios, where attackers may easily gain entry. Single-factor authentication provides minimal security compared to multi-factor authentication options, which are the best practice in securing accounts. Limiting access to local networks only can be impractical for remote access needs and does not address internal threats or compromised credentials. Therefore, the emphasis on account management and monitoring in the correct answer is essential for strengthening the security of remote access accounts.
