Remote desktop protection 101: what is a brute force attack?
One of the most easily operated, yet most effective means hackers use is trying to crack your remote desktop username and password, either manually, or using a program that tries all the possible combinations the authorized user could have come up with. This seemingly simplistic practice is called a brute force attack, and since statistics say it has been working too well, the first step towards desktop protection is nipping these attempts in the bud. Using SUN FIREWALL, you can allow the user certain numbers of failed attempts (default set at 3 ,but changeable settings) to type in the incorrect username and password, but when they try one too many times, (default set at three ), sun firewall rules that user a potential hacker and block their IP address. This method can be used for workgroup systems as well as systems worked with as an active directory.
