If passwords are appropriate in length and complexity, this setting provides little additional security.”Īssuming you’ve come down on the side of implementing an account lockout policy, are there any tools that can help you troubleshoot problems arising from locked-out accounts? The answer is yes: Microsoft provides a free set of tools called Account Lockout and Management Tools which you can download as the self-extracting file ALTools.exe from the Microsoft Download Center.

“Although account lockout settings are common, often they are the cause of numerous support calls to the help desk.

On the other hand, Ben Smith and Brian Komar on page 48 of the Microsoft Windows Security Resource Kit suggest something different:

They then go on to recommend the following account lockout policies for low, medium and high security environments: “Microsoft recommends that you use the account lockout feature to help deter malicious users and some types of automated attacks from discovering user passwords.” On the one hand, on page 3 of their white paper called Account Lockout Best Practices, they recommend the following: What should you do? Even Microsoft seems to be of two minds concerning whether to implement account lockout.

Users logging into two or more computers at once and changing their password on one of them.Īny one of the above situations can trigger an account lockout condition, and the results can include applications behaving unpredictably and services inexplicably failing.Failure of Active Directory replication between domain controllers.Disconnected Terminal Service sessions that use stale credentials.Scheduled tasks and persistent drive mappings that have stale credentials.Stale logon credentials cached by Stored User Names and Passwords in Control Panel.Stale service account passwords cached by the Service Control Manager (SCM).Applications using cached credentials that are stale.Other ways accounts can get locked out include: While these examples seem somewhat contrived since they assume an attacker has physical access to the network, it turns out account lockout is much more than just typing wrong passwords into the Log On to Windows dialog box. This demonstrates how an attacker can utilize account lockout to create a denial of service (DoS) condition. Again an annoying call to Help Desk and lost productivity on the user’s part. In this case the attacker can simply enter any random string for the user’s password 5 times in a row and suddenly the user is unable to log on to her computer. What if the attacker doesn’t care if he guesses the user’s password? Perhaps all he’s interested in is preventing the user from logging on to the network. Then comes the proverbial call to Help Desk saying “I can’t log on to my computer” and precious business resources are consumed, both in terms of the time spent resolving the problem and the loss of productivity for the user. On the other hand, if Account lockout threshold = 5 and the user hasn’t had her coffee yet, she might easily mistype her password 5 times in a row and lock herself out.

Obviously it will take some time this way to crack a password. Then after 30 minutes elapses the attacker gets another 5 attempts at cracking the password, after which he is locked out again. For example, if Account lockout threshold = 5 then after five guesses of the user’s password the user’s account could be automatically locked out for Account lockout duration = 30 minutes. On the face of it, account lockout seems like a good thing to implement as it makes it difficult for attackers to launch brute force attacks against passwords for user accounts. Account lockout threshold = 0 means the account will never be locked out no matter how many failed logons occur.Īs you can see from Figure 1 above, the default account lockout policy is that accounts are never locked out.
