Trusted Server Security
A trusted server is a computer or a software application in a domain outside of
I
NTUITY AUDIX that uses its own login and password to launch a Avaya INTUITY
Messaging Applications Programming Interface (IMAPI) LAN session and access
AUDIX mailboxes. Two examples of trusted servers are:
 Synchronizer software running on an e-mail server
 Enhanced List Application (ELA) software running as a server on the
Avaya I
NTUITY
Trusted servers can access and manipulate an AUDIX message just as the
AUDIX application can do. (See Avaya INTUITY Messaging Solutions
Administration, for in-depth discussions and definitions of trusted servers,
domains, and integration of e-mail and other trusted server software with AUDIX.)
Securing a system that allows access from another domain involves a
two-pronged approach. You must consider security from both an internal and an
external perspective. External security involves administration to prevent access
from an unauthorized source, such as a trusted server or trusted server
administrator. Internal security focuses on preventing, or recovering from, damage
if a breach occurs (for example, a virus is transmitted in a message component,
such as an attached software file).
External Security for Trusted Servers. The trusted server is empowered to do
everything to a user mailbox that an AUDIX user can do. You must administer a
password that the trusted server application uses to request a connection to the
AUDIX server. Additionally, to prevent unauthorized access through IMAPI into
your system from an external source, such as a trusted server, you can administer
an IMAPI password that the trusted server must also use when connecting to
AUDIX. This IMAPI password prevents an unauthorized source from starting an
IMAPI session and is used as a secondary layer of security in addition to the
required trusted server password.
While administration of the IMAPI password is optional, it is strongly
recommended. If you choose to administer this password, it is further
recommended that you change it on a regular basis (for example, monthly). (If you
have your administrator’s password set to age automatically, you could use the
system prompt telling you that your password must be changed as a reminder to
change the IMAPI password, as well.)
The two new trusted server screens that have been added for Release 4 are
Trusted-Server Profile and IMAPI-Password. Instructions for their
administration are in the Avaya INTUITY Messaging Solutions Administration
manual.
