Other Security Hints 1
Make sure that the Automated Attendant Selector Codes do not permit outside
line selection.
Multiple layers of security are always recommended to keep your system secure.
Following are a number of measures and guidelines that can help you ensure the
security of your communications system and voice messaging system.
Educating Users 1
Everyone in your company who uses the telephone system is responsible for
system security. Users and attendants/operators need to be aware of how to
recognize and react to potential hacker activity. Informed people are more likely to
cooperate with security measures that often make the system less flexible and
more difficult to use.
■ Never program passwords or authorization codes onto Auto Dial buttons.
Display telephones reveal the programmed numbers and internal abusers
can use the Auto Dial buttons to originate unauthorized calls.
■ Discourage the practice of writing down barrier codes or passwords. If a
barrier code or password needs to be written down, keep it in a secure
place and never discard it while it is active.
■ Instruct operators and attendants to tell their system manager when they
answer a series of calls where there is silence on the other end or the caller
hangs up.
■ Advise users who are assigned voice mailboxes to frequently change
personal passwords and not to choose obvious passwords.
■ Ensure that the system manager advises users with special telephone
privileges (such as Remote Access, Outcalling, and Remote Call
Forwarding) of the potential risks and responsibilities.
■ Be suspicious of any caller who claims to be with the telephone company
and wants to check an outside line. Ask for a callback number, hang up,
and confirm the caller’s identity.
■ Never distribute the office telephone directory to anyone outside the
company; be careful when discarding it (shred the directory).
■ Never accept collect telephone calls.
■ Never discuss your telephone system’s numbering plan with anyone
outside the company.
