Information

Limiting the number of logon attempts over a certain time interval reduces the chances that an unauthorized user may gain access to an account.

Solution

Configure the SUSE operating system to enforce a delay of at least four seconds between logon prompts following a failed logon attempt.

Edit the file '/etc/pam.d/common-auth'.

Add a parameter 'pam_faildelay' and set it to a value of '4000000' or greater:

# delay is in micro seconds
auth required pam_faildelay.so delay=4000000
