Disable SSLv3 on a VPS or Dedicated Server

Overview

This article will explain how to disable SSLv3 on a VPS or Dedicated server. This can help you avoid issues with vulnerabilities in SSLv3.



What you need

To begin, you will need to be able to login into your WHM.

Note: If this is your first time logging into the WHM, you may see a page titled Feature Showcase. Click on Exit to WHM at the bottom of the page.

Once logged in, you will need to open the Apache settings.

Open the Apache settings

  1. Type Apache in the search bar at the top left of the WHM.
  2. In the search results, click on Apache Configuration.

Change the SSL Cipher and Protocol settings

  1. On the Apache Configuration page, click on Global Configuration.
  2. The first option should be SSL Cipher Suite. Select the 2nd option, then copy this text into the box:
    ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP:!kEDH
  3. Under SSL/TLS Protocols, ensure the default setting, All -SSLv2 -SSLv3, is selected.
  4. Scroll to the bottom of the page and click the Save button.
  5. Click the Rebuild Configuration and Restart Apache button.

Note: After following these steps, it may be necessary to add "Options +FollowSymLinks" to the .htaccess file for your site.

Test the configuration

To test that SSL is disabled, you run this command:

curl -IL –sslv3 https://domain.com

Note: Replace domain.com with the domain for your site.

If SSLv3 has been disabled, you should see a message like this:

curl: (35) error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
