Control: 2.6 Ensure that account 'Lockout Threshold' is less than or equal to '10'

Description

The account lockout threshold determines how many failed login attempts are permitted prior to placing the account in a locked-out state and initiating a variable lockout duration.

Account lockout is a method of protecting against brute-force and password spray attacks. Once the lockout threshold has been exceeded, the account enters a locked-out state which prevents all login attempts for a variable duration. The lockout in combination with a reasonable duration reduces the total number of failed login attempts that a malicious actor can execute in a given period of time.
