Hi @Abdelrahman,
You should find the SSLProtocol directive in your conf file and use only the protocols you want/need.
Use this command to find the file containing the directive:
grep -ri SSLProtocol /path/to/your/apache/conf/dir/
In Debian based distributions you should use:
grep -ri SSLProtocol /etc/apache2/
In CentOS:
grep -ri SSLProtocol /etc/httpd/
Once you know where is the directive, edit the file and you should see something like this:
SSLProtocol all -SSLv3
If you only want to use TLSv1.1 and TLSv1.2 use this (note that TLSv1 actually means TLSv1.0):
SSLProtocol all -SSLv3 -TLSv1
or
SSLProtocol TLSv1.1 TLSv1.2
Once you changed the conf file, restart Apache to apply the changes.
Cheers,
