A brute force attack is a hacking technique that involves trying many different passwords with the hope of eventually guessing the right one correctly to gain access to the RDP.
The first step in any brute force attack is to choose a target. Therefore, the hackers start by scanning IP on the network and looking for open ports and then try to guess passwords.
If a hacker guesses the correct password, they’ll try to log in to the RDP. Once logged in, they’ll have complete control over the RDP server.
Methods to prevent the RDP from Brute Force attack.
1. Strong and complex password: A strong password should be at least 10 to 15 characters long and try to craft it so that it can't be guessed.
Always use the combination of letters with upper case, numbers, cases, and symbols to form an unpredictable string of characters that doesn't resemble words or names.
A strong password should be unique to each account to reduce vulnerability in the event of a hack.
2. Change the password on frequent intervals: We recommend changing your password every couple of months.
There may even be situations where you should change your password immediately, especially if you feel like a hacker has access to your account.
3. Windows OS should be updated: Regular update of the server OS helps to protect your server from unauthorize access.
4. Change default port number: You can change the default (3389) port number to any other port number of your choice which reduce the risk of being attacked by the hackers.
5. Ask Support to install Bruteforce Protection Tool: We use a specialized tool to protect against brute force attacks, this comes free of cost across all RDP plans purchased from RDP Arena.
