Abstract: PROBLEM TO BE SOLVED: To provide a method for providing security to a computer on a computer network so as to permit a remote configuration of the computer. SOLUTION: When a system meets a network supply privilege access password(PAP) during the system boot-up operation of the computer, that network supply PAP is compared with a system install PAP. The network supply PAP is stored into a first place of the non-volatile memory of the computer and the system install PAP is stored into a second place of the non-volatile memory. The system install PAP is previously inputted through a keyboard to the computer. When the network supply PAP does not match with the system install PAP, an illegality proving mechanism is set into the computer. When the network supply PAP is matched therewith, boot-up is continued. After boot-up is completed, the configuration of the computer can be remotely executed through the network.

Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. In particular, a personal computer system in accordance with this invention has a normally closed enclosure, an erasable memory element for selective activation to active and inactive states and for receiving and storing a privileged access password when in the active state, an option switch operatively connected with the erasable memory element for setting the erasable memory element to the active and inactive states, a tamper detection switch operatively connected with the erasable memory element for detecting opening of the enclosure and for clearing any stored privileged access password from the erasable memory element in response to any switching of the tamper switch, and a system processor operatively connected with the erasable memory element for controlling access to at least certain levels of data stored within the system by distinguishing between the active and inactive states of the memory element and between entry and non-entry of any stored privileged access password. In the presently preferred form of the invention, two non-volatile erasable memory elements are provided, one an EEPROM and the other battery backed CMOS RAM.

Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. This invention contemplates protecting a personal computer system which has the capability of becoming a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment, it is important to maintain network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure "alternate" which would open the network to attack through an insecure system. This invention contemplates provision for such identification in a secure manner.
