How to set up encryption for the data in transit on AWS

Data in transit encryption refers to data encryption transmitted between different endpoints, such as between a client and a server or between two servers. This is important for ensuring the data remains confidential and secure while in motion, primarily when transmitted over unsecured networks such as the internet.

How to set up data in transit encryption in AWS?

Amazon Web Services (AWS) provides various services and features to enable data-in-transit encryption. Some of the features are listed below:

Secure Sockets Layer/Transport Layer Security (SSL/TLS) is the standard protocol for encrypting data in transit. AWS provides SSL/TLS certificates that can be used to encrypt traffic to and from AWS services, such as EC2 instances, RDS databases, and ELB load balancers. Follow the steps below to set up this feature:

  1. Obtain an SSL/TLS certificate for your AWS resource from a trusted certificate authority (CA), or use the free certificates provided by AWS Certificate Manager.

  2. Install the SSL/TLS certificate on your AWS resources, such as an EC2 instance or ELB load balancer.

  3. Configure application or service to use HTTPS, which encrypts traffic using SSL/TLS.

  4. Test the setup to ensure that traffic is encrypted using SSL/TLS.

Virtual private network

A virtual private network (VPN) provides an extra layer of security by encrypting traffic between two endpoints. AWS provides VPN services such as AWS site-to-site VPN and AWS client VPN. Follow the steps given below to set up a VPN:

  1. Create a virtual private gateway in your virtual private cloud (VPC) to act as the VPN concentrator.

  2. Create a customer gateway to represent your on-premises VPN device.

  3. Create a VPN to connect the virtual private gateway to the customer gateway.

  4. Configure the VPN connection to encrypt traffic using IPsec.

  5. Test the setup to ensure that traffic is encrypted using the VPN connection.

AWS PrivateLink allows us to access services within our virtual private cloud (VPC) without going online. This ensures that our data remains secure and reduces the risk of data breaches. Follow the steps given below to set up an AWS PrivateLink:

  1. Create an interface VPC endpoint for the AWS service you want to access using PrivateLink.

  2. Configure your VPC to route traffic to the endpoint.

  3. Create a security group to control access to the endpoint.

  4. Test the setup by accessing the AWS service using its private IP address.

AWS direct connect provides a dedicated network connection between our on-premises infrastructure and AWS. This provides a more reliable and secure connection than a standard internet connection. To set up AWS direct connect, follow the steps given below:

  1. Choose a direct connect partner to connect your on-premises infrastructure to AWS.

  2. Order a direct connect port from the partner.

  3. Configure the direct connection to use a virtual private gateway.

  4. Test the setup to ensure traffic is routed through the direct connection.

AWS certificate manager

AWS certificate manager efficiently manages SSL/TLS certificates for our AWS resources. This includes provisioning, managing, and deploying SSL/TLS certificates for our AWS resources. To set up the AWS certificate manager, follow the steps mentioned below:

  1. Request an SSL/TLS certificate using the AWS certificate manager for your AWS resource.

  2. Verify that you own the domain associated with the certificate.

  3. Deploy the certificate to your AWS resource.

  4. Test the setup to ensure that traffic is encrypted using the certificate.
