Netra j 2.0 Administrator's Guide

Network Service Access Administration

The Netra server provides a number of generic network services that do not have administration modules associated with them. These services enable users to access information and facilities on the server. You can restrict access to any or all of these services using the Network Service Access module. Restricting access to all services helps ensure the security of your network.

For each network service there are three access modes. The service can be denied to all hosts; the service can be made available to a specified list of hosts and networks (using a control list); or the service can be made available to all hosts. All services using the control list access mode share one access control list.

The following network services are available on your Netra server:

To Control Access to Network Services
  1. From the Main Administration page, under "Security Administration," click Network Service Access.

    The Network Service Access Administration page is displayed with a list of the server's network services and corresponding access levels.

  2. Choose the access mode for each network service using the information in Table 5-3.
