Infrastructure security in AWS Secrets Manager

As a managed service, AWS Secrets Manager is protected by the AWS global network security. For information about AWS security services and how AWS protects infrastructure, see AWS Cloud Security. To design your AWS environment using the best practices for infrastructure security, see Infrastructure Protection in Security Pillar AWS Well‐Architected Framework.

Access to Secrets Manager via the network is through AWS published APIs using TLS. Secrets Manager APIs are callable from any network location. However, Secrets Manager supports resource-based access policies, which can include restrictions based on the source IP address. You can also use Secrets Manager resource policies to control access to secrets from specific virtual private cloud (VPC) endpoints, or specific VPCs. Effectively, this isolates network access to a given secret from only the specific VPC within the AWS network. For more information, see Using an AWS Secrets Manager VPC endpoint.
