Single datacenter with NBAC on master and media servers
The single datacenter with NBAC on master servers and media servers example uses the NetBackup Access Control on the master servers and media servers. This configuration limits access to portions of NetBackup and provides non-root administration of NetBackup. NBAC is configured for running between the servers and the GUIs. Non-root users can log in to NetBackup with operating system (UNIX password or Windows local domain) or global user repositories (NIS/NIS+ or Active Directory) to administer NetBackup. NBAC can be used to limit the level of access to NetBackup for certain individuals. For example, you can segregate day to day operational control from environmental configuration such as adding new policies, robots, etc.
The single datacenter with NBAC on master and media servers includes the following highlights:
Administer non-root users
Administer UNIX with a Windows User ID
Administer Windows with a UNIX account
Segregate and limit the actions of specific users
Root or Administrator or client hosts can still do local client backups and restores
Can be combined with other security-related options
All servers must have the required NetBackup version
Figure: Single datacenter with NBAC on master and media servers shows an example single datacenter with NBAC on master and media servers.
The following table describes the NetBackup parts that are used for a single datacenter with NBAC on the master and media servers.

Communicates with the media server, root, and authentication broker. It also communicates with the authorization engine, clients 1, 2, 3, and client 5, Web server, in the DMZ. The master server also communicates with and receives a credential from the authentication broker.
When a CLI or GUI accesses a daemon on a master server, a credential is exchanged to identify the user. The authorization engine is then contacted to determine accessibility to the daemons functions.
Communicates with the master server, clients 1, 2, 3, and client 5, Web server, in the DMZ. The media server also communicates with the authorization engine and receives a credential from the authentication broker. The media server enables the writing of unencrypted data to tape for clients 1, 2, 3, and 5.
When a CLI or GUI accesses a daemon on a media server, a credential is exchanged to identify the user. The authorization engine is then contacted to determine accessibility to the daemons functions.
Specifies that this remote administration console GUI receives a credential from the authentication broker. The GUI then uses this credential to gain access to functionality on the media servers and master servers.
Authenticates the authentication broker but not the clients. In this example, the root broker and authentication broker are shown as the same component.
Authenticates the master server, media server, and GUI by establishing credentials with each. If a command prompt is used, the authentication broker also authenticates a user.
Communicates with the master server and media server to determine permissions of an authenticated user. These permissions determine the functionality available to the user. It also stores user groups and permissions. Only one authorization engine is needed.
The authorization engine resides on the master server as a daemon process. It is shown in the figure as a separate image for the example only.
Contains unencrypted backup data that is written for clients 1, 2, 3, and 5.
Specifies that clients 1, 2, and 3 are standard NetBackup types and client 5 is a Web server type. Both types are managed by the master server and have their unencrypted data backed up to tape through the media server. Clients 1, 2, and 3 exist in the datacenter. Client 5 exists in the DMZ. Client 5 communicates to NetBackup using NetBackup only ports through the internal firewall. Client 5 receives connections from the Internet using HTTP only ports through the external firewall.
Allows NetBackup to access Web server Client 5 in the DMZ. Only selected NetBackup ports and possibly other application ports are enabled for data communication into and out of the DMZ. HTTP ports that are open in the external firewall are not allowed to pass through the internal firewall.
Demilitarized Zone (DMZ)
Provides a "safe" area of operation for Web server client 5 that exists between the internal firewall and external firewall. The Web server client 5 in the DMZ can communicate to NetBackup through the internal firewall using designated NetBackup ports. The Web server client 5 can communicate through the external firewall to the Internet using HTTP ports.
Allows external users to access the Web server client 5 located in the DMZ from the Internet over HTTP ports. NetBackup ports are open for client 5 to communicate through the internal firewall. NetBackup ports are not allowed to pass through the external firewall to the Internet. Only the HTTP ports of client 5 can pass through the external firewall to the Internet.
Specifies a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, and wireless connections. Client 5 can communicate over the Internet using HTTP ports through the external firewall.
