Idea 1: Security Zones within a BladeChassis System A BladeChassis system can be made to have security zones by using a representation of different security zones within a management module and having the management module create the zones by configuration of the integrated chassis switch. Idea 2: Information Flow Control Between Regions of a BladeChassis System A BladeChassis system can have different regions. The allowable flow of information (e.g., IP Packets) between the regions, PATHS, is definable and the limations on the characteristics of the flow can also be defined with security or flow-control mechanisms.

(BC) - Access control of blade users to blade chassis management information and flows

     This publication illustrates: Idea1: SECURITY ZONES: This publication illustrates an apparatus comprising a chassis with a plurality of blades, a chassis/central management module and a plurality of switch modules and a method in which the apparatus creates distinct security zones within the apparatus. The zones comprise a chassis management zone and a plurality of user zones with multiple levels of authority/security within the zones.

The method of zone creation comprising the steps of
1) a user representation of the zones within the management entity,
2) a linkage of the zone representation to the switch(es),
3) the instantiation of the zones by the switch. The representation of the zones is a tree with the chassis management at the top, user zones as leaves, with each leaf of a given layer able to access all leaves in lower layers.

    Zone representation is illustrated in the following figure, Figure 1: A member of the Chassis Management zone can access all functions in the UserX_Zones and in UserX.Y_Zones. A user in Userx_Zone can access all functions in the Userx.Y_Zone. A user in the User1_Zone can not access users in the User2_Zone and likewise a user in User1.1_Zone can not access a user in the User1.2_Zone except via a level 3 device such as a router. For the purposes of this publication, a router is outside the scope of the apparatus. Chassis Management Zone

Figure 1: Zone Representation

    The linkage of the zone representation is via a command line interface to the switch with the management module sending switch VLAN configuration commands either on demand of the user(s), periodically or when zone representation change is made.

    The separation of zones at the leaf and subleaf levels are via port and/or tagged VLANs created by the switch(es). There are multiple VLAN methods for creation of zone separation. One method is for all zones to be distinct VLANs with users given membership in multiple VLANs, as illustrated in Figure 1b. Chassis Management Zone (VLAN1)
