Short post on disabling SSLv3 for POODLE in Centos 7.
1. Run the following:
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.
sudo systemctl systemctl restart httpd
sudo service httpd restart
