Ensure that Account 'Lockout duration in seconds' is at least 60 seconds

中レベル 1手動レビューm365

説明

The account lockout duration value determines how long an account retains the status of lockout, and therefore how long before a user can continue to attempt to login after passing the lockout threshold. The recommended state is Lockout duration in seconds is at least 60. 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.
