(under the class definition) Subject matter further including means or steps for increasing a system's extension of protection of system hardware, software, or data from maliciously caused destruction, unauthorized modification, or unauthorized disclosure to or by an end user.
(1) Note. This class is for protection against unauthorized use by a user. Fault recovery and locating, and fault detecting in a digital data processing system that is maliciously caused (e.g., by a computer virus), or the result of other unauthorized access, is classified elsewhere. See the SEE OR SEARCH CLASS notes below.
(2) Note. Means or steps to prevent incorrect memory access requests that are not a system end-user request are classified elsewhere. See the SEE OR SEARCH CLASS notes
below.
(3) Note. Authorization control without significant data processing features is classified elsewhere. See the SEE OR SEARCH CLASS notes below.
