ALMA-09-007610 - AlmaLinux OS 9 must automatically lock the root account until the root account is released by an administrator when three unsuccessful logon attempts occur during a 15-minute time period.

Information

By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-force attacks, is reduced. Limits are imposed by locking the account.

Solution

Configure AlmaLinux OS 9 to lock the root account after a number of incorrect login attempts using pam_faillock.

First, enable the feature using the following command:

$ authselect enable-feature with-faillock

Then, add or uncomment the following line in the "/etc/security/faillock.conf" file:

even_deny_root
