What is AWS Security Hub and How it works?

The Security Hub provides a single place in the AWS environment to aggregate, organize, and prioritize security alerts and discoveries from multiple AWS security services. This may be Amazon Guard Duty, Amazon Inspector, Amazon Macie, IAM, Access Analyzer, AWS Firewall Manager. But it also supports third-party partner products.

Security Hub provides a pre-built dashboard to help organize and prioritize any issues or alerts for your AWS environment discovered from security checks.

This helps you check your environment against AWS security industry standards and best practices. You can also take advantage of PCI-DSS and CIS (centre for Internet Security) built-in automatic checks. Security Hub can help you automate your security findings. Security Hub is a more comprehensive security platform that offers integration with other AWS security tools.

How does Security Hub work?

Security Hub simplifies how you understand and improve your security position with automated security best practice checks powered by AWS Config rules and automated integrations with dozens of AWS services and partner products.

Security Hub only detects and consolidates findings that are generated after you enable.
