Techniques for reorganizing security levels without implicating accessibility
to secured files classified in accordance to one of the security levels are disclosed.
In a case of adding a new security level, the controllability or restrictiveness
of the new security level is determined with respect to the most restrictive security
level or the least security level in a set of existing security levels. A set of
proper security parameters are then generated for the new security level and subsequently
the existing security levels are reorganized to accommodate the new security level.
In a case of removing a security level from the existing security levels, the security
parameters for the security level to be deleted are either folded up or down to
an immediate next security level, depending on implementation. As a result, the
security parameters for the immediate next security level are updated to include
those for the security level to be deleted such that the secured files classified
at the security level to be deleted can still be accessed by those with proper
clearance levels.
