APPENDIX G GLOSSARY

minimum filtering level - A set of library categories and service ports defined at the global level to be blocked or opened. If the minimum filtering level is established, it is applied in conjunction with a user’s filtering profile. If a user does not belong to a group, or the user’s group does not have a filtering profile, the default (global) filtering profile is used, and the minimum filtering level does not apply to that user.

name resolution - A process that occurs when the R3000 attempts to resolve the IP address of the authentication server with the machine name of that server. This contin- uous and regulated automated procedure ensures the connection between the two servers is maintained.

net use - A command that is used for connecting a computer to—or disconnecting a computer from—a shared resource, or displaying information about computer connec- tions. The command also controls persistent net connec- tions.

NetBIOS - Network Basic Input Output System is an appli- cation programming interface (API) that augments the DOS BIOS by adding special functions to local-area networks (LANs). Almost all LANs for PCs are based on the NetBIOS. NetBIOS relies on a message format called Server Message Block (SMB).

NetBIOS name lookup - An authentication method used for validating a client (machine) by its machine name.

Network Address Translation (NAT) - Allows a single real IP address to be used by multiple PCs or servers. This is accomplished via a creative translation of inside “fake” IP addresses into outside real IP addresses.

open setting - A setting assigned to a service port or library category when creating a rule, or when setting up a filtering profile or the minimum filtering level. If an item is given an open (pass) setting, users will have access to it.
