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■ An unpublished remote access number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.
