Authorization
Authorization is the process of granting or denying access to a resource. Most
computer security systems are based on a two-step process. The first stage is
authentication, which ensures that users are who they claim to be. The second stage is
authorization, which allows the user access to various resources based on the user's
identity.
AVSP (Avocent Video Session Protocol)
A protocol used to transfer keyboard, video and mouse information between a KVM
switch and a remote Video Viewer. AVSP operates over SSL encrypted TCP links.
TCP/IP ports 8192 and 2068 are used by default, but may be configured to different
port numbers.
Browser session
A type of target device session in which the target device contains a web server. The
DSView 3 software client connects directly to the target device using a web browser,
without directing the connection through the unit.
Cascade device
A device that connects between a KVM switch or serial console appliance and a target
device, or connects to a KVM switch or serial console appliance and is not, in itself, a
target device. Examples of cascade devices include a cascade switch and a power
device.
Cascade switch
A cascade switch is an analog KVM switch connected to a KVM switch port or IQ
module. A cascade switch expands the number of connections allowed on a KVM
switch if the switch supports the cascade protocol.
CCM appliance
A CCM console management appliance is an Avocent managed appliance that
provides a Telnet server and an SSH server for accessing serially attached devices over
a standard TCP/IP connection. Model numbers include the CCM850, CCM1650 and
CCM4850 appliances.
Certificate authentication
