Elastic Cloud offers a security feature known as traffic filtering, which provides network layer security by restricting access to deployments from specified networks through the use of IP or CIDR-based rules. This is combined with role-based access control (RBAC) to enhance security measures. The service supports integration with major cloud providers such as AWS, Azure, and Google Cloud, allowing for the implementation of traffic filters that leverage AWS PrivateLink for private connectivity. This ensures that traffic remains within the AWS network, avoiding exposure to the public internet. Customers can configure multiple rule sets for a single deployment, associating them with specific IP addresses or AWS VPC endpoints to control access. The AWS PrivateLink traffic filter is available at no additional cost and is implemented by creating a VPC endpoint and DNS records, followed by configuring and applying the traffic filter rules within the Elastic Cloud console. This setup provides a secure way to manage network access to Elastic deployments, and users can monitor and analyze traffic patterns using Elastic VPC and Route53 integrations for enhanced visibility.
