Amazon GuardDuty enhances security primarily through its capability for threat detection and continuous monitoring of AWS accounts and workloads. This service utilizes machine learning, anomaly detection, and integrated threat intelligence to identify potentially malicious activity and unauthorized behavior within an AWS environment.

By continuously analyzing data from various sources, including AWS CloudTrail event logs, Amazon VPC Flow Logs, and DNS logs, GuardDuty can detect threats like account compromise, unusual API usage, and reconnaissance activity. Once a threat is identified, it generates findings which can alert administrators, allowing them to respond quickly to potential issues. This proactive monitoring mechanism is vital for maintaining a strong security posture and ensuring that any threats are promptly addressed before they can lead to significant damage or data breaches.

The other options focus on different aspects of security management, such as compliance checks, user access management, and data encryption, which, while important, are not the core function of GuardDuty itself. GuardDuty is specifically designed for threat detection and monitoring, making that feature critical to its role in enhancing AWS security.
