# 10.4 Ensure that HTTPS is enabled on load balancer (Manual)

## Description

The simplest way to use HTTPS with an Elastic Beanstalk environment is to assign a server certificate to your environment's load balancer.

## Rationale

When you configure your load balancer to terminate HTTPS, the connection between the client and the load balancer is secure.

## Impact

N/A

## Audit Procedure

### Using AWS Console
