Security
Overview
NOTE
This chapter supports the
operation of dial access security
for COMSPHERE 3800
Plus
modems. This chapter is
self-supporting and can be
removed to prevent unwanted
knowledge of dial access
security operation.
Although the security functions
described in this chapter are
designed to prevent unwanted
user access to your network, the
company recognizes that no
security system is infallible.
Dial Access Security is an optional feature that allows
you to control who has access to your 3800Plus modem
and ultimately your host DTE.
To take advantage of this security feature, you must
create a database of passwords which are stored in the
modem’s nonvolatile memory. The 3800Plus modems can
store a maximum of 20 passwords. (A 3811Plus with the
optional Password Expansion Feature can store up to
3000 passwords.) Each password is assigned a series of
parameters that determine the type of security protocol
applied to it. This protocol is established in the Security
branch of the Top-Level menu. Control of security
functions is established in the Security Configuration
Options group which is located in the Configure branch of
the Top-Level menu. These areas are described in the
Security Branch section of this chapter and the Security
Configuration Options section of Chapter 8, Configure
Branch.
The 3800Plus modem uses an outbound and inbound
method of security known respectively as Originate
Access and Answer Access security. Both methods of
security require some type of password entry whether it be
included as part of an AT command dial string or entered
directly from a remote user’s DTE.
