Choosing Passwords
Passwords should be the maximum length allowed by the system.
Passwords should be hard to guess and should not contain:
„ All the same numbers (for example, 1111, 666666)
„ Sequential characters (for example, 123456)
„ Numbers that can be associated with you or your business, such as your
name, birthday, business name, business address, telephone number, or
social security number
„ Words and commonly used names
Passwords should be changed regularly—at least on a quarterly basis. Recycling
old passwords is not recommended. Never program passwords (or authorization
codes or barrier codes) onto a speed dial button.
Physical Security
You should always limit access to the system console (or attendant console) and
supporting documentation. The following are some recommendations:
„ Keep the system console and supporting documentation in an office that is
secured with a changeable combination lock. Provide the combination only
to those individuals having a real need to enter the office.
„ Keep telephone wiring closets and equipment rooms locked.
„ Keep telephone logs and printed reports in locations that only authorized
personnel can enter.
„ Design distributed reports so they do not reveal password or trunk access
code information.
„ Keep the voice messaging system Remote Maintenance Device turned off.
