Short post on disabling SSLv3 for POODLE in Centos 7.
Run the following:
1 2 3
sudo vi /etc/httpd/conf.d/ssl.conf # Inside you can find the SSLProtocol directive. If this is not available, create it. Modify this to explicitly remove support for SSLv3: SSLProtocol all -SSLv3 -SSLv2
Save and close the file. Restart the service to enable your changes.
