| Summary: | A security system for a computer operating system comprising a processor that is independent of the host CPU for controlling access between the host CPU and a security partition formed in the storage device for storing the operating system. A program memory that is independent of the computer memory and the storage device unalterably stores and provides computer programs for operating the processor in a manner so as to control access to the security partition in the storage device. All data access by the host CPU to the data storage device is blocked before initialization of the security system and is intercepted immediately after the initialization under the control of the processor. The processor effects independent control of the host CPU and configuration of the computer to prevent unauthorised access to the security partition on the storage device during the interception phase. All users of the computer are authenticated with a prescribed profile of access to the operating system files in the security partition on the storage device and data access to the storage device remains blocked until a user of the computer is correctly authenticated. |
