Protect your computer against brute force attacks

Today is the day, today you will learn how to protect your computer from brute force attacks.
I will be using Windows Vista to demonstrate this.

First you need to access you Advanced User Controls
1. Click the Start button, click All Programs, click Accessories, click Run and type userpasssword2
With Vista click OK
2. Click the Advanced tab, select the Require users to press Ctrl+Alt+Delete check box, and click OK













Now to lockout the accounts after 5 incorrect attempts to log in.
I was not successful in finding out how to accomplish this task in XP.
The only one we wont be able to lockout will be the built-in Administrator account.
1. Click the Start button, click Control Panel,and click Administrative Tools
With Vista click OK
2. Double-click Local Security Policy
3. In the left window pane expand Account Policies and click on Account Lockout Policy
4. Double-click Account lockout threshold, type 5 and click OK
5. Double-click Account lockout duration, type 5 and click OK



Click OK as many times needed and close all windows.
Log off
and you will notice that the next time you log on you will be required to hold Ctrl+Alt+Delete.
You have now made it very difficult for someone to break into your computer.
