PC-Duo security features

One of the most valuable aspects of PC-Duo remote desktop solutions is the ability to

create and enforce fine-grained access control policies, and to easily modify them to

PC-Duo security features include the following:

 “Authentication”

 “Auditing”

“servers”. For example, the PC-Duo Master is considered a client when it connects to and

requests a list of Hosts from a PC-Duo Gateway. In turn, the PC-Duo Gateway is

considered a client when it connects to and requests information from a PC-Duo Host in

the same domain.

When PC-Duo Host is not in the same domain as the Gateway, the relationship is

automatically reversed: The Host is programmed to be the client and will reach out to the

Gateway (see “Firewall-friendly connections” for more information about PC-Duo firewall-

friendly connections).

To guarantee security in the PC-Duo environment, it is critical that PC-Duo components

acting as servers validate the credentials of users of PC-Duo components acting as

clients before they provide access or data. The burden is placed on the client to
