AWS Certified Security Specialty SCS-C02 Practice Test 2025 – Complete Exam Prep

Amazon GuardDuty is a managed threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect your AWS accounts and workloads. It uses machine learning, anomaly detection, and integrated threat intelligence to identify potential threats in real time. When suspicious activity is detected, GuardDuty provides actionable security alerts that inform you of the potential dangers, allowing you to respond promptly to protect your AWS environment.

This service stands out because it works seamlessly with other AWS services, automatically processing and analyzing data from various sources such as AWS CloudTrail logs, VPC flow logs, and DNS logs. The real-time analysis enables organizations to maintain a proactive security posture against evolving threats, making it an essential tool for any AWS security strategy.

Other services mentioned have distinct roles: AWS Security Hub acts as a centralized dashboard to aggregate, organize, and prioritize security alerts from multiple AWS services, but it does not provide real-time detection itself. AWS Inspector is focused on assessing the security of applications by identifying vulnerabilities during the development process rather than identifying threats in real time. AWS Config is primarily for monitoring resource configurations and compliance over time, not for detecting active security threats.
