General Security Measures
Criminals called hackers may attempt to gain unauthorized access to your
communications system and voice messaging system in order to use the system
features. Hackers often attempt to trick employees into providing them with access
to a network facility (line/trunk) or a network operator. This is referred to as social
engineering. Hackers may pose as telephone company employees and employees
of Lucent Technologies or your authorized dealer. Hackers will go through a
company's trash to find directories, dialing instructions, and other information that
will enable them to break into the system. The more knowledgeable they appear to
be about the employee names, departments, telephone numbers, and the internal
procedures of your company, the more likely it is that they will be able to trick an
employee into helping them.
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.
