A company needs to set up secure database credentials for all its AWS Cloud resources. The company’s resources include Amazon RDS DB instances, Amazon
DocumentDB clusters, and Amazon Aurora DB instances. The company’s security policy mandates that database credentials be encrypted at rest and rotated at a regular interval.
Which solution will meet these requirements MOST securely?

  1. Set up IAM database authentication for token-based access. Generate user tokens to provide centralized access to RDS DB instances, Amazon DocumentDB
    clusters, and Aurora DB instances.
  2. Create parameters for the database credentials in AWS Systems Manager
    Parameter Store. Set the Type parameter to SecureString. Set up automatic rotation on the parameters.
  3. Store the database access credentials as an encrypted Amazon S3 object in an
    S3 bucket. Block all public access on the S3 bucket. Use S3 server-side encryption to set up automatic rotation on the encryption key.
  4. Create an AWS Lambda function by using the SecretsManagerRotationTemplate template in the AWS Secrets Manager console. Create secrets for the database credentials in Secrets Manager. Set up secrets rotation on a schedule.
