WARNING: Protecting the Branch Servers
Because Branch Servers contain sensitive information, they must be secured
against unauthorized access. Close unused ports and allow only the root user
to have access to the server console. Refer to Chapter 8, Securing Your Setup
(page 111) for more details on how to protect your SUSE Linux Enterprise Point
of Service setup.
SUSE Linux Enterprise Point of Service is broadly scalable so that a small shop with
five Point of Service terminals can be managed just as well as a large chain with a
thousand branches. For organizations with several Branch Servers, the link between
the branch and administrative servers is maintained over WAN. During execution of
administrative tasks, such as the installation of new Point of Service terminals in a
branch, steps must be taken to ensure that the WAN link to the Administration Server
is available.
The SUSE Linux Enterprise Point of Service architecture is highly centralized. However,
administrative tasks can also be performed on subunits for role-based administration.
The Branch Server provides all the services necessary for the operation and management
of the Point of Service terminals and the LDAP database can be replicated on the Branch
Server. Consequently, the Branch Server and Point of Service terminals can function
independently of the Administration Server in the event of server failure or downed
connection.
