Infrastructure security in Amazon Secrets Manager
As a managed service, Amazon Secrets Manager is protected by the Amazon global network security. For information about Amazon security services and how Amazon protects infrastructure, see Amazon Cloud Security
Access to Secrets Manager via the network is through Amazon 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 Amazon network. For more information, see Using an Amazon Secrets Manager VPC endpoint.
