Servers are protected with software-based firewalling. These look at source and destination addresses, and source and destination ports.

Our systems are secured using the latest security methods including router access list filtering on inbound carrier feeds and firewalling at the SYN level on internal devices. Security systems, including firewalls, are tested on a monthly basis. We use security scanners that are automatically updated instantly with the latest exploit/DOS check codes. This provides us with an accurate and detailed report on our systems. Our security team is also subscribed to all the major security mailing lists, including BUGTRAQ from securityfocus.com. These lists provide access to the latest security information, which enables us to patch newly found exploits within hours of their discovery.
