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.
n
No one outside of AT&T needs to use the MERLIN LEGEND
Communications System to test facilities (lines/trunks). If a caller
identifies him or herself as an AT&T 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 AT&T 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 network facilities or
operators, or to dial a number at the request of the caller.
