Depending on how your Apache servers are configured, you may need to disable SSL v3.
Note older versions of Internet Explorer may not have the TLS protocol enabled by default. If you disable SSL versions 2.0 and 3.0, the older versions of Internet Explorer will need to enable the TLS protocol before they can connect to your site.
Locate your SSL Protocol Configuration on your Apache server.
Type one the following commands:
In these examples, /etc/apache2 and /etc/httpd are the base directory for an Apache installation.
For a list of default base directories and installation layouts in Apache HTTPD for different operating systems, see DistrosDefaultLayout.
If that command doesn’t find the “SSLProtocol” string, then look for SSLEngine by typing one of the following commands:
The command will output the available Virtual Hosts or your config file.
Open the config file or Virtual Host for which you are disabling the SSL v3 protocol.
Add or update the following lines in your configuration:
If you used the grep -i -r 'SSLEngine'… command, you need to search for “SSLEngine On” and add SSLProtocol all -SSLv2 -SSLv3 in the line beneath it.
For example, type the following command:
You have successfully disabled the SSL v3 protocol.
