Toll Fraud Prevention
Preventive Measures
Take the following preventive measures to limit the risk of unauthorized access
by hackers:
Provide good physical security for the room containing your
telecommunications equipment and the room with administrative tools,
records, and system manager information. These areas should be
locked when not attended.
Provide a secure trash disposal for all sensitive information, including
telephone directories, call accounting records, or anything that may
supply information about your communications system. This trash
should be shredded.
Educate employees that hackers may try to trick them into providing
them with dial tone or dialing a number for them. All reports of trouble,
requests for moving extensions, or any other administrative details
associated with the MERLIN LEGEND Communications System should
be handled by one person (the system manager) or within a specified
department. Anyone claiming to be a telephone company
representative should be referred to this person or department.
No one outside of Lucent Technologies needs to use the MERLIN
LEGEND Communications System to test facilities (lines/trunks). If a
caller identifies him or herself as an Lucent Technologies employee, the
system manager should ask for a telephone number where the caller
can be reached. The system manager should be able to recognize the
number as an Lucent Technologies telephone number. Before
connecting the caller to the administrative port of the MERLIN LEGEND
Communications System, the system manager should feel comfortable
that a good reason to do so exists. In any event, it is not advisable to
give anyone access to private network facilities or operators, or to dial a
number at the request of the caller.
Any time a call appears to be suspicious, call the Lucent Technologies
GBCS Fraud Intervention Center at 1 800 628-2888 (fraud intervention
for System 25, PARTNER
® ®
and MERLIN systems).
