What is the primary function of AWS Security Hub?

The primary function of AWS Security Hub is to provide centralized visibility of security alerts. It serves as a comprehensive security management solution that aggregates, organizes, and prioritizes security findings from various AWS services and third-party security tools. By consolidating security alerts into a single dashboard, AWS Security Hub allows organizations to have a holistic view of their security posture and helps identify potential vulnerabilities or threats across their AWS environment. This centralized visibility is crucial for efficient incident response and proactive security management.

Managing user identities, encrypting data, and offering backup solutions are important aspects of security and compliance but are not the main focus of AWS Security Hub. Instead, user identity management is typically handled by services like AWS IAM, data encryption is managed through AWS KMS and similar services, and backup solutions might be provided by AWS Backup or Amazon S3, not by Security Hub itself.
