The Weak Password Detection module shows an administrator any user accounts, extensions or trunks that have weak registration passwords. Weak passwords represent a huge security risk and should be updated as soon as possible.
No single security practice will keep you secure. This module should be used as part of an overall security strategy
If the module detects weak passwords it will flag the extensions in the report so you can update them. A system with no detected weak passwords will show the above screen upon logging in.
If weak passwords are detected they will appear in the report with a reason for the detection.
In newer versions of FreePBX the secret field will automatically populate with a secure password. If you override the generated password, the Extensions module, by default, will prompt you to enter passwords that are at least six characters and contain both numbers and two alpha characters.
When Creating an Extension- The PBX will prompt you to enter a valid password if it does not pass validation, however, weak extensions can be registered to the system by:
In the event you have hardware that is incompatible with the strong password validation, you can remove the requirement by adjusting the device settings in the Advanced Settings Menu of your PBX.
Require Strong Secrets - Toggle this option to False and then save to remove the “Strong Secrets” data validation when creating extensions.
It is recommended to always use complex extension passwords. The latest version of the PBX software will auto generate a strong alpha-numeric password with 32 digits. Although the system will only report on weak passwords when less than 6 digits, it is a best practice to use stronger passwords. When combined with an endpoint manager, there is no additional hardship by using the longer passwords and it adds an additional barrier to enhance the security of your PBX.
