Discussion

By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.

Check Content

Verify that "Number of invalid attempts permitted per login" is set to "3", and "Lockout period (when threshold breached)" is set to "15", as shown in the example below:

- show system security password-options

Number of invalid attempts permitted per login   : 3
Lockout period (when threshold breached)         : 15

If the "Number of invalid attempts permitted per login" is not set to "3", this is a finding.

If the "Lockout period (when threshold breached)" is not set to "15", this is a finding.

Fix Text

Configure the Nokia router using the command below:

- configure system security password attempts 3 lockout 15
