NETBuilder Security NETBuilder security can be obtained many ways including limiting the access to a particular network or by limiting the access to certain files. Limiting access to a particular network can be accomplished by building Internet firewalls. Limiting access to particular files can be accomplished by using certain commands and parameters.

Building Firewalls for A firewall allows users inside a private network to have outbound access, while Security restricting outside users from inbound access. For more conceptual information about firewall and its capabilities, and details on how to configure firewalls, see

Using Enterprise OS Software. For a description and syntax of the various firewall service parameters, see Reference for Enterprise OS Software.

Security Commands and To make sure that some designated files are accessible only to the system Parameters administrator, use the following commands and parameters:

■NetAccess

This parameter is a SYS Service parameter that determines how a bridge/router can be accessed from another device on the network. For information on how to use the NetAccess parameter, see Using Enterprise OS Software and Reference for Enterprise OS Software.

■SysPassWord

This command brings up a menu allowing you to specify the password for the Network Manager and User privilege levels. For information on how to use the SysPassWord command, see Reference for Enterprise OS Software.

■RemoteManager

This parameter is a SYS Service parameter that specifies the Internet addresses of devices that can connect to the bridge/router through the REMote command. For information on how to use the RemoteManager parameter, see Using Enterprise OS Software and Reference for Enterprise OS Software.

■COMmunity

This parameter is an SNMP Service parameter that modifies the list of communities. For information on how to use the COMmunity parameter, see Using Enterprise OS Software and Reference for Enterprise OS Software.

What Next?You are now ready to see Using Enterprise OS Software to configure your bridge/router for your specific network needs.
