Security in AWS Elastic Disaster Recovery


Cloud security at AWS is the highest priority. As an AWS customer, you benefit from a data center and network architecture that is built to meet the requirements of the most security-sensitive organizations.

Security is a shared responsibility between AWS and you. The shared responsibility model describes this as security of the cloud and security in the cloud:

  • Security of the cloud – AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. AWS also provides you with services that you can use securely. Third-party auditors regularly test and verify the effectiveness of our security as part of the AWS Compliance Programs . To learn about the compliance programs that apply to AWS Elastic Disaster Recovery (AWS DRS), see AWS Services in Scope by Compliance Program .

  • Security in the cloud – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your company’s requirements, and applicable laws and regulations

This documentation helps you understand how to apply the shared responsibility model when using AWS DRS. It shows you how to configure AWS DRS to meet your security and compliance objectives. You also learn how to use other AWS services that help you to monitor and secure your AWS Elastic Disaster Recovery resources.

The customer is responsible for making sure that no misconfigurations are present during and after the recovery process, including:

  1. The replication server should be accessed only from the CIDR range of the source servers. Proper security groups rules should be assigned to the replication server after it is created.

  2. After the recovery, the customer should make sure that only allowed ports are exposed to the public internet.

  3. Hardening of OS packages and other software deployed in the servers is completely under the customer’s responsibility and we recommend the following:

    1. Packages should be up to date and free of known vulnerabilities.

    2. Only necessary OS/application services should be up and running.

  4. Activating the Anti-DDOS protection (AWS Shield) in the customer's AWS Account to eliminate the risk of denial of service attacks on the replication servers as well as the migrated servers.
