During our lesson last week we discovered how to create the overall policy structure (Create_Policy) to define our various label components (a label may have one or more Hierarchical Level, zero or more compartments, and zero or more groups; Create_Level, Create_Compartment, Create_Group). The next step is create the particular sets of level, compartment, and groups that are allowed (the Sensitive level (S) may not have all of the Compartments (NATO, NOFO, ATOM, CYBR, VEGAS) but only have a subset of the possible levels (in the example below the Sensitive level has only two compartments (NATO & ATOM). Slide 2: Creating the Data label. The purpose of the data label is to map the compartment and group part of the label to the hierarchical part of the label. In other words at the Sensitive (S) level what compartments exist and what groups exists. In this example the label_value is S:NATO,ATOM:EU. This means there are two compartments defined at the S level namely NATO and ATOM. This also means that there is one group defined for the compartment ATOM, namely EU. Remember a parent in the group hierarchy includes all of its children, e.g., EU (Europe) includes its children G (Germany) and S (Sweden). Slide 3:
