Information

OL 9 must maintain an account lock until the locked account is released by an administrator.

GROUP ID: V-271755
RULE ID: SV-271755r1091977

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.

Satisfies: SRG-OS-000329-GPOS-00128, SRG-OS-000021-GPOS-00005

Solution

Configure OL 9 to lock an account until released by an administrator after three unsuccessful logon attempts with the command:

$ sudo authselect enable-feature with-faillock

Then edit the "/etc/security/faillock.conf" file as follows:

unlock_time = 0
