Fix Recommendation

Navigate to and open:

/etc/security/faillock.conf

Add or update the following lines:

silent

Note: On vCenter appliances, the equivalent file must be edited under "/etc/applmgmt/appliance", if one exists, for the changes to persist after a reboot.

Check Contents

At the command line, run the following command to verify account information is not leaked during the login process:

# grep '^silent' /etc/security/faillock.conf

Example result:

silent

If the "silent" option is not set, is missing or commented out, this is a finding.

Note: If faillock.conf is not used to configure pam_faillock.so then these options may be specified on the faillock lines in the system-auth and system-account files.
