Regularly change passwords
What it is:
Having varied and complex passwords
The best ways to create passwords is a phrase-based method.
Choose a password comprised of a sentence and put hyphens between the words
This creates a very long and very complex password that is very difficult to break
A best practice is to set up secure PINs and passwords to the phone system, such as voicemail access, extension lines, and other features that may be compromised if accessed remotely. Conference phones can also be a high target area, which is often forgotten about with poor usernames and passwords. If companies have a lot of passwords for multiple accounts as well as their PBX system, they might find it beneficial to invest in the use of a password generation and saving system.
