Access Security
Accessing the Control from a remote location is protected against
compromise by the use of 4 levels of protection:
1.
Security Code Handshake: The subscriber's account number as well as
an 8-digit ID number (known only to the office) must be matched
between the Control and computer.
2.
Hang-Up and Call-Back: The Control panel will "hang-up" and call the
computer back at the pre-programmed number only if the security codes
match.
3.
Data Encryption: All data that is exchanged between the computer and
Control is encrypted to reduce the possibility of anyone "tapping" the line
and corrupting data. Additionally, all account files are encryped to
prevent them from being opened on another installer's VLink®
downloading software package.
4.
Operator Access Levels: Up to 15 operators can have access to the
DOWNLOADER, each having their own log-on code. However, each
operator can be assigned one of three levels of access in both FILE and
COMMAND functions, as follows:
FILE ACCESS:
Read Only: able only to look at the database; cannot change any
information, and cannot see the customer's access codes.
Part Read/Write: able to look at and change all information. except the
customer's access codes.
Full Read/Write: able to look at and change any and all information in
the database.
CONTROL/COMM ACCESS:
Read Only: able only to Upload and arm the system. Not able to
DISARM, BYPASS, or change any information.
Part Read/Write: able to ARM, BYPASS, UPLOAD, DOWNLOAD but
cannot shutdown the system.
Full Read/Write: able to perform all control and status commands, as
well as shutdown all or part of the system.
NOTES:
1.
Each time the Control panel is accessed successfully, a CALLBACK
REQUESTED report is sent to central station, if programmed.
2.
When downloading, the keypad displays "MODEM COMM."
3.
Whenever a download or a save is done, an automatic time stamp is
done, indicating the date and time of the last download (or save) and the
operator ID number.
4.
A complete hard copy of each individual account can be obtained by
connecting a printer to the computer. Refer to your computer owner's
manual or contact your dealer for printer recommendations.
