About OVO Security About Network Security 488 To set or change the security level: a. Open the OVO Node Bank window. b. Click the node for which you want to change the security level. c. Change the default settings for all or individual nodes: All Nodes Change the default setting for all nodes: Actions:Node->Set Defaults->Communication Options Individual Node Change the default setting for an individual node: Actions:Node->Modify->Communication Options d. Fill in the relevant fields in the Communication Parameters section of the Node Defaults Communication Options window or Node Communications Options window. For information about the options provided, see the OVO online help. e. Close the Node Defaults Communication Options window or Node Communication Options window. f. Click [OK] in the OVO Node Defaults or Modify Node window. g. If you receive critical messages in the message browser, restart the management server processes. Chapter 12
About RPC Authentication About OVO Security About Network Security The DCE security mechanism enables you to protect communication between the OVO management server and its managed nodes using DCE RPC. An important step in the authentication procedure of the DCE RPC process is getting a login context. About the RPC Login Context A secure RPC process has a login context, which it either inherits from its parent process or establishes itself. The login context requires a name (principal) and a password (key), both of which are checked by the DCE security server prior to a connection. Because OVO processes usually run without any user interaction, reliance on an inherited login context is not suitable. As a result, the OVO processes create their own login context with a name and password that must be registered at the DCE security service. About the RPC Server Ticket RPC clients use the login context to get a server-specific “ticket” that is then passed with each RPC. The client obtains this ticket from the DCE security service only if it has already passed the authentication process. This ticket contains a key that is not visible to the client application. It is known only to the security service and the server. Verifying the RPC Ticket The RPC server verifies the ticket using the server password in the key file. The RPC server rejects non-matching RPCs. If a client receives a successful response from the server, an authentic server processed the request. The only information the server has at this point is whether the client is authentic. The server extracts the following information from the RPC password: ❏ Client name ❏ Level of protection the client has chosen After the authentication process has completed successfully, a connection is established, and the RPC call sequence initiates.
