Amazon Linux 2023 must automatically lock an account when three unsuccessful logon attempts occur.

GROUP ID: V-274154RULE ID: SV-274154r1120450

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. Limits are imposed by locking the account.

Solution

Configure Amazon Linux 2023 to lock an account when three unsuccessful logon attempts occur.

Add/modify the "/etc/security/faillock.conf" file to match the following line:

deny = 3
