Security Issues

■ Change passwords frequently (at least quarterly). Set password

expiration times and tell users when the changes go into effect.

Changing passwords routinely on a specific date (such as the first of the

month) helps users to remember to do so.

■ Establish well-controlled procedures for resetting passwords.

■ Limit the number of invalid attempts to access a voice mail to five or less.

■ Monitor access to the dial-up maintenance port. Change the access

password regularly and issue it only to authorized personnel. Consider

using the Remote Port Security Device (RPSD) — a Lucent

Technologies product that helps protect your administration and

maintenance ports from unauthorized access.

■ Create a PBX system management policy concerning employee turnover

and include these actions:

— Delete all unused voice mailboxes in the voice mail system.

— If an employee is terminated, immediately delete any voice

mailboxes belonging to that employee.

— If a terminated employee had Remote Access calling privileges

and a personal authorization code, remove the authorization code

immediately.

— If barrier codes and/or authorization codes were shared by the

terminated employee, these should be changed immediately.

Notify the remaining users as well.

— If the terminated employee had access to the system

administration interface, their login ID should be removed (G3V3

or later). Any associated passwords should be changed

immediately.

■ Back up system files regularly to ensure a timely recovery should it be

required. Schedule regular, off-site backups.

■ Keep the attendant 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.
