What is AWS Security Hub and how does it aggregate security findings from multiple sources?

Beginner

Answer

AWS Security Hub provides a centralized view of your security posture across an AWS account or organization, automatically aggregating findings from services like GuardDuty, Inspector, and Macie, along with checks against security standards such as the Center for Internet Security benchmarks, giving security teams a single dashboard to review and prioritize security issues instead of needing to check multiple separate services individually.
