Disa Security; Forced Account Codes - Samsung OfficeServ 7000 Series System Administration Manual

NOTE: Outgoing DISA calls are controlled by the dialing class of the station identi-
fied by the security code.The DISA line must have disconnect supervision from the
central office. Insist that this service is verified by your installation/service company.

DISA SECURITY

A common practice among hackers is to repeatedly dial a known DISA access
number (usually with a computer) and try a different passcode each time. The
hacker hopes to eventually chance upon the correct passcode and thus gain
access to your system. The OfficeServ 100, OfficeServ 500, and OfficeServ 7000
Series security feature counts the number of sequential incorrect passcode
attempts. If a certain number is reached, DISA is disabled and the system sends an
alarm to designated display stations. The number of passcode attempts and the
disable duration are both programmable. In addition, the OfficeServ 100,
OfficeServ 500, and OfficeServ 7000 systems will print an SMDR record (a cus-
tomer-provided printer is required) each time an incorrect passcode is entered.
The DISA alarm will ring for a programmable time before canceling the ringing;
however, the DISA alarm display will remain until the alarm is cleared. To clear the
DISA alarm, follow the following procedure:
• Lift the handset and dial 58.
• Enter the DISA alarm passcode (see your service company).
• Replace the handset.
As it is impossible to prevent unauthorized access to your telephone sys-
tem by hackers, we suggest that you do not turn the DISA feature on unless
you intend to use it. If you do use this feature, it is good practice to fre-
quently change passcodes and periodically review your telephone records
for unauthorized use.
