METHOD AND SYSTEM FOR PROTECTING WEB SITES FROM PUBLIC INTERNET THREATS

摘要

The present invention addresses the known vulnerabilities of Web site infrastructure by making an origin server substantially inaccessible via Internet Protocol traffic. In particular, according to a preferred embodiment, the origin server is "shielded" from the publicly-routable IP address space. Preferably, only given machines acting as clients can access the origin server, and then only under restricted, secure circumstances. In a preferred embodiment, these clients are the servers located in a "parent" region of a content delivery network (CDN) tiered distribution hierarchy.
