Description​

Ensure that all applicable AWS DMS endpoints are configured to use Secure Sockets Layer (SSL) to encrypt data in transit. AWS DMS establishes connections to your source and target data stores using these endpoints.

Supported SSL modes:

  • require – Encrypts the connection using SSL/TLS without certificate authority (CA) verification. Provides baseline encryption with minimal configuration.

  • verify-ca – Encrypts the connection and verifies the server’s certificate against a trusted CA. Enhances authenticity by validating the certificate chain.

  • verify-full – Encrypts the connection, validates the server’s certificate, and ensures the certificate’s hostname matches the endpoint’s configured hostname. Offers the highest level of trust and integrity.

Not all SSL modes work with all database endpoints. The following table shows which SSL modes are supported for each database engine.

From Command Line​

Import the CA Certificate into DMS​

If you do not yet have your CA certificate registered with DMS, import it first:

aws dms import-certificate \
    --certificate-identifier {{cert-identifier}} \
    --certificate-pem file://{{path-to-cert}}.pem

Sample output:

{
  "Certificate": {
    "CertificateIdentifier": "{{cert-identifier}}",
    "CertificateCreationDate": "2025-07-11T18:00:00Z",
    "CertificateArn": "{{cert-arn}}"
  }
}

Note the {{cert-arn}} for use in the next step.

Enable SSL on the Endpoint​
aws dms modify-endpoint \
    --endpoint-arn {{endpoint-arn}} \
    --ssl-mode require \
    --certificate-arn {{cert-arn}}

--ssl-mode: Choose one of require, verify-ca, or verify-full according to your security requirements.

Test the Endpoint Connection​
aws dms test-connection \
    --replication-instance-arn {{replication-instance-arn}} \
    --endpoint-arn {{endpoint-arn}}
