<p>In a computer system, each program has a program attribute list associated with it, for associating different aggregates of program attributes with each of a number of invocation contexts in relation to that program. In operation, a process is given attributes depending on the current context/program combination, as determined by the program attribute table for that program. The program attributes may, for example, include a set of privileges and the context may include the identity of the user on whose behalf the program is to be run, so that a program can be given different sets of privileges depending on which user runs the program.</p> |
