    You can create an account lockout policy with GPO & then you can edit for practices that what parameters you asked. For more information, please link here, https://searchfinancialsecurity.techtarget.com/tip/Password-management-best-practices-for-financial-services-firms

    For me personally, I would not reset the login for an employee unless they call in for support and can verify their credentials. Whether it was 15 min or even an hour, I would not reset it. If someone was try to breach the system and they found the magic time of the reset, they would adjust the hack attempt cycle based on that parameter.  A good rule of thumb is to never reset your password on a Friday. You tend to forget it over the weekend. Change it on a Monday or Tuesday and you will be reinforcing the new password by using it the next day.

    For most 'brute force' account logon attacks, even just one or two minutes would be enough... as long as you are monitoring for attacks. Brute force requires a large number of attempts in a short time... hundreds at least per minute. (And at that low rate, there'd likely be multiple remote devices trying concurrently. So it should be obvious to a monitor.)

    If network security isn't monitored, there might be no good amount of time to specify.
