COMPUTER IMPLEMENTATION METHOD FOR MANAGING ACCESS TO DOMAIN NAME SERVICE (DNS) DATABASE, COMPUTER PROGRAM, AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To enable authorization of DNS request messages, such as queries and update requests corresponding to user and network address information. SOLUTION: An authorization function can be incorporated into existing DNS systems. The method includes: receiving a DNS request message originated from a client by a user, the DNS request message comprising a request and identification information specific to the user; determining whether the client is authorized to access a DNS database in dependence upon client address information and the user specific identification information contained in the DNS request message; and executing the request in response to determining the user is authorized. The method further includes extracting user specific identification information from a part of the ID field of DNS messages. COPYRIGHT: (C)2011,JPO&INPIT
