Current Intel-based computer architecture, at least from the iAPX-286 CPU onwards, owes its security structure in large part to the earlier MULTICS program. This developed from the 1960s to late 1970s to create a secure, time-shared computing environment. However, in current commodity operating systems of today the major security principles of that architecture are largely ignored. This paper discusses this failure of systems and supporting software systems to use well established security hardware features in computers as a failure in education related to IT security, and even software engineering, over at least the last twenty year period. At the same time, IT systems managers are being asked to consider enhanced security in relation to National Information Infrastructure Protection (NIIP) as a cooperative effort between Government and the private sector, against growing international standards.
