Process execution controls as a mechanism to ensure consistency

A mechanism for ensuring that the changes to a system and its data occur in a consistent manner is presented. The mechanism, process execution controls, imposes restrictions on the method of access to the data, unlike access controls which impose restrictions upon which users can access the data. This mechanism imposes another layer to the currently existing access control restrictions, but one that is, for the most part, transparent to the user. Although transparent, the system offers the capability of containing viruses within a given domain. The author presents two methods of implementation; extending current access control lists and implementing complementary execution control lists
