Access Rules

Applies to the SSL VPN feature. When a user tries to log in
to the VPN server, either through the Portal page or through a
VPN client, his or her group membership determines the access
rights to different servers and applications on the intranet. This is
done by associating one or more access rules (each containing
parameters such as allowed network, ports and paths) with a
group.

ARP

Address Resolution Protocol. A network layer protocol used
to convert an IP address into a physical address, such as an
Ethernet address. A host wishing to obtain a physical address
broadcasts an ARP request onto the TCP/IP network. The host
on the network that has the IP address in the request then replies
with its physical hardware address.

Base Profile

Refers to links and access rules specified for a user group directly
under the Group level. If extended profiles are used, the base
profile’s links and access rules will be appended to the extended
profile’s links and access rules.

CA (Certificate Authority)

A trusted third-party organization or company that issues digital
certificates. The role of the CA in this process is to guarantee that
the entity granted the unique certificate is, in fact, who he or she
claims to be.

CLI (Command Line Interface)

The text-based interface pertaining to the NVG software,
presented to the user after having logged in. The CLI can be
accessed through a console connection or remote connection
(Telnet or SSH). The CLI is used for collecting information and
configuring the NVG.
