authentication throttling and temporary account lockout

[Fabio Martelli]

Hi All, is there someone that can give me some tips to implement temporary account lockout after 3 consecutive failed login attempts?

It seems that authentication throttling is something really different. If I got it, authentication throttling is used to temporary inhibit successful authentication attempts after a failed one.

For example, with a configuration like as

• failureThreshold: 3
• failureRangeInSeconds: 300

If a failed authentication attempt occurs, all the following attempts will fails (resulting in 423) for 100 seconds (300/3 -> thresholdRate 0.01).

As anticipated, I would lockout a user after 3 consecutive failed login attempts occurred within 60 seconds. Is it possible?

Thank you in advance for your help.

BR,

F.

Fabio,

The threshold throttle is a rate. In your example it works out to 1 failed attempt in 100 seconds. Any user will try a second time within that 100 seconds. Set the numbers to a reasonable user action time - how long does it take for a user to type and press enter, maybe 5 seconds. Set threshold at 1 and range at 5.

Hi Ray, thanks a lot for your reply.
Unfortunately this is not my requirements. I need to lock a user out after three consecutive failed login attempts.
As far as you know, is there a way to implement this feature?

Thank you in advance for your further reply.

Many LDAP and RDBMS implementations have a failed-authentication lockout feature, if you're using that as a credential store.
