ABSTRACT:
An authorized client communication system seeking access to a host communication system may be identified by locating a memory segment within the client communication system that stores client software used to access the host computer system. The memory segment then is examined to determine whether the client software stored in the memory segment corresponds to client software for an official client communication system. Communications from the client communication system are terminated when the client software in the memory segment is determined to diverge from software for an official client communication system.
