Security violations notification
When a security violation occurs, security violations notification (SVN) notifies a 
designated referral point. This can be an attendant console, a display-equipped 
phone, or a phone without display for SVN referral calls with announcements.
The system monitors and reports on the following types of security violations:
Login violations
Remote access barrier code violations
Authorization code violations
Station security code violations
DEFINITY ECS provides the option to log a major alarm if a security violation 
occurs involving a Lucent Technologies services login ID. Lucent Technologies is 
responsible for retiring the alarm.
Refer to DEFINITY ECS Reports for more information on how to run reports, and 
respond to security violations.
To effectively monitor the security of your system, you need to know how often 
both valid and invalid attempts at system entry are normally made. Then you will 
know if the number of invalid attempts is unusually high. A significant increase in 
such attempts can mean the system is being compromised.
NOTE:
It is recommended that you print and clear the security-violation 
measurement reports at least once a month. In a busy system, once a week is 
not too frequent.
Security violation thresholds and notification
As an example, you may determine that during a forty-hour week, it’s normal for 
users to submit about 1,000 valid barrier codes and 150 invalid barrier codes; that 
is, about 3.75 invalid barrier codes are submitted per hour.
With this information, you may decide to declare that a security violation occurs 
during any hour in which 8 invalid barrier codes are submitted. If you know that 
during an 8-hour period, about 30 invalid codes are submitted, you might set the 
threshold to count a security violation when 40 invalid codes are submitted within 
eight hours.
You can administer SVN to place a referral call to the location of your choice 
whenever the established thresholds are reached. All SVN referral calls are 
priority calls.
