A computer system uses security labels for evey word in memory. Each access to a memory location requires that the security level of the memory location be compared to that of a process which is making the access. If the security level of the process does not dominate that of the memory location, access is denied. Each time a memory location is modified, it is assigned a security level consistent with the levels of all of the data which was used to modify the memory location.
