Discussion

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.

Check Content

Password policy is set with the Passcode Policy configuration profile.

/usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep 'maxFailedAttempts\|minutesUntilFailedLoginReset'

If "maxFailedAttempts" is not set to "3" and "minutesUntilFailedLoginReset" is not set to "15", this is a finding.

Fix Text

This setting may be enforced using the "Passcode Policy" configuration profile or by a directory service.
