DEFINITY Enterprise Communications Server Release 8.2
Overview
555-233-002
Issue 1
April 2000
The risks of unauthorized access can be minimized by combining the use of Remote
Network Access with the following:
■ An unpublished remote access number
■ Deactivate unassigned barrier codes immediately
■ Change barrier codes frequently
■ Inform remote access users of their responsibility
■ Monitor call detail reports for unauthorized or abnormal calling patterns
Class of Restriction (COR)
Defines many different classes of call origination and termination privileges. DEFINITY
ECS may have no restrictions, only a single COR, or may have as many classes of
restrictions as necessary to effect the desired restrictions. Many different types of classes
of restriction can be assigned to many types of facilities on the switch. For example, you
can use a calling-party COR to prevent callers from accessing the public network.
Security Violation Notification (SVN)
Security Violation Notification (SVN) allows you to set security-related parameters and to
receive notification when the limits that you have established are violated. You can run
reports related to both valid and invalid access attempts. You can also disable a login ID
or remote access authorization that is associated with a security violation.
Station Security Codes
To provide additional security around the customer options the “init” login has been
provided with additional security for the purpose of establishing an authentication
procedure for attempts to remotely log into the system.
