When you are securing a system
that allows access from another domain, you must consider both internal
and external security.
External Security
External security involves administration
to prevent access from an unauthorized source. These sources can include
a subscriber who is administered to use email or remote AMIS analog
networking. Users might send "mail bombs" to an enhanced-list. Mail
bombs are harassing messages that not only do not serve your business
needs, but also impose unnecessary traffic on your system.
ELA mailboxes are no more vulnerable
to unauthorized use than are any other voice mailboxes. However, the
impact on system performance can be many times greater.
To prevent unauthorized access to an ELA mailbox from an external source such as email users or remote AMIS Analog networking users, you can place those subscribers in a community with sending restrictions.
Internal Security
Internal security focuses on preventing or recovering from damage if a breach occurs, for example, if a virus is transmitted in a message component such as an attached software file.
INTUITY AUDIX allows for the transmission
of two message components, text (originating from Message Manager or email)
and binary file attachments (software files, such as a spreadsheet or word-processing
file). With these components come related security considerations, namely,
the inadvertent delivery of a computer virus that could be embedded in a
file attachment. This problem can occur in any system that supports the
delivery of software files. While the AUDIX machine cannot be infected with
viruses embedded in these software files, client machines can become infected
when a user launches the application associated with the software file.
ELA does not perform any virus detection. The customer needs to evaluate
the security risks of file attachments carefully and make provisions
for virus detection software on PCs running Message Manager or an
email application supported by INTUITY AUDIX.
At a minimum, advise your users to detach (that is, not launch)
file attachments and scan them for viruses before use.
