Abstract
During pre-boot (i.e., the period of time prior to initiating operation of the workstation operating system), a networked workstation performs an intrusion detection hashing function on selected workstation executable program(s). A computed hash value calculated by the hashing operation is compared against a trusted hash value that is downloaded from a server in order to detect illicit (i.e., authorized) changes to the selected workstation executable programs.
