CISC-ND-000150 - The Cisco router must be configured to enforce the limit of three consecutive invalid logon attempts, after which time it must lock out the user account from accessing the device for 15 minutes.

Information

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

Solution

Configure the Cisco router to enforce the limit of three consecutive invalid logon attempts as shown in the example below.

R2(config)#login block-for 900 attempts 3 within 120
