METHOD AND APPARATUS FOR MONITORING CLOCK-RELATED PERMISSION ON A COMPUTER TO PREVENT UNAUTHORIZED ACCESS |
摘要 |
To prevent unauthorized access on a computer, a clock monitoring system having a memory for storing a permission database having one or more permission fields, each field comprising one or more clock-related permissions, a time-value field comprising a stored time-value, and a clock-monitor in communication with the permission database. The clock-monitor reads a first time-value from a system clock, determines whether the permissions database is initialized, and if the permission database is initialized, compares the first time-value to the stored time-value. If the first time-value is later than the stored time-value, the clock-monitor stores the first time-value in the stored time-value field. If the first time-value is earlier than the stored time-value, the clock-monitor disables the one or more clock-related permissions, thereby preventing access to the data. If the permissions database is not initialized, the clock-monitor stores the first time-value in the stored time-value field.
