Data is the lifeblood of any organization, and its secure flow is crucial for operational integrity. AWS services are designed to work in an interconnected manner, often requiring data to move from one service to another. For example, logs from CloudTrail can be ingested into Security Lake for deeper analysis. While this inter-service data flow is generally secure, additional measures such as encryption during transit and at rest, enabled by KMS, can add an extra layer of security. This data flow should also be secured using IAM roles and policies that grant least-privilege access.
