Proxy Directory Guard
View500 can be used as a Proxy X.525 Directory server when deployed in the Directory Guard scenario. In this scenario 2xView500 licences are deployed with the Clearswift EAL 4 evaluated Directory Bastion Guard solution. The Clearswift Directory Bastion role is to provide assured network separation supporting only the DISP ITU-T Rec. X.525 protocol between explicitly identified Directory servers deployed in a Red Black network configuration where data is required to be synchronised between directory servers on two otherwise disjointed networks.. That is two networks operating at different classification levels or similar levels, but where classified network separation is required. In this View500 is deployed on both sides of the Directory Bastion as a Directory Bastion and supports strong authentication for all server to server operations. Because DISP is the standard protocol to synchronise directory data between View500 DSAs, a Directory Bastion can be inserted between two View500 DSAs without requiring anything other than normal shadowing agreement configuration on the View500 DSAs. Apart from network level addressing, the Directory Bastion is entirely transparent to the View500 DSAs.
