✔ When using remote desktops, RDP security and RDPGuard must be your main priority.

✔ It is vital for protecting your servers from password-guessing brute force attempts, which are a way to gain access to your protected servers.

✔ These days, brute-force attacks and malware are fairly common. You must strengthen your system, whether you’re on Windows, Linux, or other OSs.

✔ Most servers are constantly under brute force attack, and RDPGuard is a good choice to defend the servers from this particular form of attack.

 

Introduction

Many windows servers and desktops run RDP (Remote Desktop Protocol) to allow users to gain access into the machines remotely. But there is a broad army of devices that will attempt brute force attacks on machines running RDP. If they find a server’s IP, they begin to try password combinations. In most cases, they try to login as an administrator user.

Replacing the administrator account with an account with a different name and changing the RDP listening port are a couple of strategies for slowing down this process. However, port scans would also identify the right ports. You need to run a high-end firewall.

The ability to ban an IP after a given number of failed attempts is one thing that is missing in all these solutions. This article will assist you with RDP security and RDPGuard and you will learn how to use RDPGuard tools to deal with RDP security issues and block suspicious IPs.

 

What Is a Brute Force Attack?

A brute force attack uses trial-and-error to guess login data, encryption keys, or access a protected web page.  Hackers, hoping to guess correctly, work through all possible combinations.

These attacks are carried out by brute force. It means they use a very large number of attempts to eventually force their way into your private account. This is an old method of attack, but for hackers, it’s still successful and common. It can take anything between a few seconds and several years to crack a password, depending on its length and complexity.

Brute-force is one of the most common attacks to gain access to RDP login information.  The hacker uses this method to test all possible words to get access. Hackers always attempt to hack RDPs, and there are several reasons for doing that.

The most significant reason is that the RDP connections are not protected by most RDP users. Prevention is better than treatment; blocking the IP that repeatedly tries to log in to your RDP is an easier solution.

 

How Brute Force Attacks Benefit Hackers?

To make these schemes pay off, brute force attackers have to put in a bit of effort, though technology makes it simpler.  The advantages of brute force attacks for hackers are:

  • Profiting from obtaining commercials or activity data
  • Hackers may use a website to earn advertising commissions
  • Stealing personal data and items of value
  • It is possible to find anything online from bank accounts to tax records. All it takes for a criminal to steal your identity, assets, or sell your private credentials for profit, is the right break-in.
  • Spreading malware to create interruptions

If a hacker wants to cause problems or exercise their abilities, they may redirect the traffic of a website to malicious sites.

  • Hijacking your system for malicious activity

Hackers recruit an army of unsuspecting equipment called a botnet to speed up their activities

  • Ruining the reputation of a website

If you run a website and become a victim of hacking, a cybercriminal may decide to vandalize your site with obscene content.

Why Do you Need an RDPGuard?

There are numerous Windows Server machines under constant attack. Network scanners and tools for RDP brute force run 24/7. They can eventually find a password for your server to access! In addition, RDP brute force attacks misuse system resources such as CPU, RAM, Disk Space, and Network Bandwidth.

How do you secure your server from password-guessing attacks on RDP by brute force? The solution is RDPGuard, a powerful tool that enables you to defend your Remote Desktop from attacks by brute force. RDPGuard works as a Windows Service. Even when no one is logged in, your Windows Server will be safe.

 

What Is RDPGuard and How Does it Work?

Remote Desktop Protocol allows users to connect from anywhere to a remote server. RDP is indeed a very helpful tool, but it also has some security problems.

RDPGuard is a host-based intrusion prevention system (HIPS). This system defends your Windows Server against brute-force attacks on multiple protocols and services, such as:

  • RDP
  • FTP
  • IMAP
  • POP3
  • SMTP
  • MySQL
  • MS-SQL
  • VoIP/SIP
  • IIS Web Login
  • NET Web Forms
  • MS Exchange
  • RD Web Access

Using the Windows firewall and system event log, RDPGuard identifies and automatically blocks suspicious IPs. You will be able to identify which ports and resources you should protect while configuring this software.

It tracks the logs and detects failed login attempts on your server. If the number of failed attempts to log in from a single IP address exceeds a defined limit, the IP address of the attacker will be blocked for a given period of time.

What Is the Difference between VDI and RDP

VDI and RDS are alternative desktop virtualization and remote desktop technologies. RDS uses Remote Desktop Protocol or RDP as its basis.

3 Steps to Secure RDP against Brute Force Using RDPGuard

1. Download RDPGuard from its Website

Download it from the RDPGuard website.

2. Install RDPGuard on Windows Server

Choose Next after running the downloaded file to start the operation. Check the accept agreement box and click Next.

RdpGuard Setup Agreement

Pick the destination path for the setup, or you can set it to a default value and click Next. In the next section, you will be asked whether or not you want to create a desktop shortcut and whether you want it for the current user or for all users.

Now, the installation is complete. Check the Start RdpGuard now button and click Finish.

3. RDPGuard Configurations and Settings.

Upon opening the app, you will be able to see that RDP service security is allowed by default. In that case, you don’t need to make any changes. Some minutes after installation, it readily starts to block certain IPs.

RdpGuard Protection Setting

You can go to Tools>Options for custom configurations. You can allow or disable automatic updating on the General page. You can set the maximum failed log-in attempts from a single IP address (3 attempts by default.)

Sometimes you might pass the maximum failed log-in attempts yourself; with setting Reset counters failed logon attempts after you can log in after the specified hours (24 Hours by default.)

With Unban IP address automatically after, you can unban all blocked IPs after a given time. If you want to enable another service’s protection, you can easily select Disable behind any service to enable it.

Final Thoughts

When using remote desktops, RDP security and RDPGuard must be your main priority. After you buy an RDP server or enable RDP on your system, it can be hacked easily if you are not careful about certain scenarios, one of them being brute-force attacks.

When a malicious user executes network or port scanners or RDP brute force attacks, hundreds of failed login attempts are generated and dozens of pages are being logged. These attacks misuse the resources of your VPS or dedicated server and degrade the server’s overall functionality.

This is vital for protecting your servers from password-guessing brute force attempts, which are a way to gain access into your servers. These days, brute-force attacks and malware are fairly common. You must strengthen your systems, whether you’re on Windows, Linux, or other OSs.

Most servers are constantly under attack, and RDPGuard is a good choice to defend the servers from this particular form of attack.

 

How Does RDPGuard Work?

It tracks the logs and detects failed log-in attempts on your server. The IP address of the attacker will be blocked for a given period of time if the number of failed attempts to log in from a single IP address exceeds a defined limit. This is crucial for protecting your servers from password-guessing brute force attacks.
