Star Topology
In a star topology configuration, the remote branches can communicate securely with the corporate headquarters or central site. However, intercommunication between the branches is not permitted. Such a configuration could be deployed in a bank network so that compromise of one branch will not immediately lead to the compromise of a second branch without being detected. To gain access to a second branch, the attacker would have to first compromise the central network that would hopefully be able to detect such an attack. A star topology configuration is shown in Figure 5.6. Star topologies provide an inherent advantage that a new site can be added with ease; only the central site will have to be updatedIn star topology, the central site plays an important role; if it fails, all the connections will go down. Performance of the central hub dictates the performance of the connection. For a star topology, it may happen that two nodes might be closed to each other; however, they will have to communicate via central node.
