Insecurity of the Internet. CONNECTION TO THE INTERNET CREATES INSECURITY. Security and disruption problems are inherent in the Internet. The very openness of the Internet creates risks that the Internet is insecure, and vulnerable to both intentional and unintentional disruption. Security breaches can occur for technical and other reasons, and, despite the implementation of security measures, we cannot guarantee that our networks are not vulnerable to unauthorized and illegal access, computer viruses and other disruptive problems. Our ability to provide our services depends in part on the reliability of the Internet and the networks of our partners, and our services can also be negatively affected by limitations inherent in the technology infrastructure supporting the Internet and the internal networks of Internet users. Customer must provide adequate information security for their own networks by using appropriately complex passwords, firewalls, and updated anti-virus and anti-spyware software.
