ALB Endpoints Now Support SSL_PROTOCOLS_OVERRIDE

Thomas Orozco on February 14, 2017

As of last week; ALB Endpoints respect the SSL_PROTOCOLS_OVERRIDE app configuration variable, which was — until now — only applicable to ELB Endpoints.

In a nutshell, setting SSL_PROTOCOLS_OVERRIDE lets you customize the protocols exposed by your Endpoint for encrypted traffic.

For example, if you have a regulatory requirement to only expose TLSv1.2, you can do so using the following command (via the Aptible CLI):

1
aptible config:set FORCE_SSL=true "SSL_PROTOCOLS_OVERRIDE=TLSv1.2" --app my-app

Note that by default (i.e. if you don’t set SSL_PROTOCOLS_OVERRIDE), Aptible Endpoints accept connections over TLSv1, TLSv1.1, and TLSv1.2. This configuration will evolve over time as best practices in the industry continue to evolve.

You can learn more about the SSL_PROTOCOLS_OVERRIDE configuration variable (and other variables available) on our support website: How can I modify the way my app handles SSL?
