![Protect Your Business: The Risks of Publicly Exposed RDP](https://contenu.nyc3.digitaloceanspaces.com/journalist/1bd7dcc9-dccd-4ddf-a459-1c9458ef0eeb/thumbnail.jpeg)
In today's digital landscape, securing remote access to business systems is more critical than ever. Remote Desktop Protocol (RDP) is a common tool used by businesses to facilitate remote work, but when exposed to the public internet, it poses significant risks. This article explores the dangers of publicly exposed RDP and provides strategies to secure it, assess and mitigate risks, and consider alternative remote access solutions.
Key Takeaways
- Businesses should remove RDP from the public internet to decrease the risk of being targeted by cybercriminals.
- Identify where you have RDP exposed, assess that risk, and follow hardening and security guidelines to minimize potential fallout from attacks.
- Consider alternative solutions such as Remote Desktop Gateways, Zero Trust Network Architecture, and cloud-based remote access solutions to enhance security.

Increased Vulnerability to Cyber Attacks
When RDP is exposed to the public internet, it becomes a beacon for cybercriminals. Hackers are well aware that RDP is integral to many business operations, making it a prime target. In fact, research has shown that a significant portion of malicious traffic is RDP-related. This exposure can lead to various types of cyber attacks, including brute force attacks and exploitation of known vulnerabilities like BlueKeep.
Potential for Unauthorized Access
Publicly exposed RDP significantly increases the risk of unauthorized access. Attackers can exploit weak passwords or unpatched vulnerabilities to gain entry into your network. Once inside, they can move laterally, compromising other systems and data. This not only jeopardizes sensitive information but also undermines the overall security posture of the organization.
Impact on Business Continuity
The consequences of a successful RDP attack can be devastating for business continuity. Systems can be taken offline, data can be encrypted or stolen, and the recovery process can be lengthy and costly. The downtime and financial losses associated with such incidents can be crippling for any business.
It's crucial to understand that leaving RDP exposed on the internet is an open invitation to cybercriminals. The risks far outweigh any perceived convenience.

Implementing Virtual Private Networks (VPNs)
One of the most effective ways to secure RDP is by using a Virtual Private Network (VPN). A VPN can prevent unauthorized individuals from even seeing that RDP exists within your organization. This adds an extra layer of security by ensuring that only specific IP addresses can access the RDP service. Additionally, it creates additional steps in the login experience, which means users will need to be trained appropriately.
Utilizing Multi-Factor Authentication (MFA)
Implementing Multi-Factor Authentication (MFA) is another crucial step. MFA requires users to provide two or more verification factors to gain access, significantly reducing the risk of unauthorized access. This is especially important for protecting against rogue sessions and hijacking attempts.
Regularly Updating and Patching Systems
Regular updates and patches are essential for maintaining the security of your RDP setup. Rigorous patch management can help prevent exploits and vulnerabilities that could be used to gain unauthorized access. Make sure to keep all systems up-to-date to mitigate potential risks.
Assessing and Mitigating RDP Risks
Identifying Exposed RDP Instances
First and foremost, it's crucial to identify where you have RDP exposed. This involves scanning your network to detect any instances of RDP that are accessible from the internet. Tools like network scanners can be invaluable in this process. Once identified, you can take steps to secure or eliminate these exposures.
Conducting Risk Assessments
After identifying exposed RDP instances, the next step is to conduct a thorough risk assessment. This involves evaluating the potential impact of an RDP-related breach on your business. Consider factors such as the sensitivity of the data accessible via RDP and the potential for unauthorized access. A comprehensive risk assessment will help you prioritize mitigation efforts.
Applying Security Best Practices
To mitigate the risks associated with RDP, it's essential to apply security best practices. This includes:
- Regularly updating and patching systems to address vulnerabilities.
- Implementing strong authentication mechanisms, such as multi-factor authentication (MFA).
- Limiting RDP access to only those who absolutely need it.
- Using encryption to protect data transmitted via RDP.
By following these best practices, you can significantly reduce the risk of a successful cyber attack on your RDP instances.
In conclusion, the mitigation of cybersecurity threats requires a proactive approach to identifying and securing exposed RDP instances. By conducting risk assessments and applying security best practices, you can protect your business from the dangers of publicly exposed RDP.
Alternatives to Publicly Exposed RDP
When it comes to securing remote desktop access, exposing RDP to the public internet is a recipe for disaster. Fortunately, there are several robust alternatives that can help mitigate these risks effectively.
Using Remote Desktop Gateways
One of the most effective ways to secure RDP is by using Remote Desktop Gateways. These gateways act as intermediaries between the client and the server, ensuring that only authenticated users can access the network. This method significantly reduces the risk of unauthorized access and cyber attacks.
Adopting Zero Trust Network Architecture
Another powerful strategy is to adopt a Zero Trust Network Architecture. This approach operates on the principle of "never trust, always verify," meaning that every access request is thoroughly vetted before granting entry. By implementing this architecture, businesses can ensure that only legitimate users gain access to sensitive systems.
Exploring Cloud-Based Remote Access Solutions
Lastly, cloud-based remote access solutions offer a secure and scalable alternative to traditional RDP. These solutions often come with built-in security features such as encryption, multi-factor authentication, and continuous monitoring. By leveraging these cloud services, businesses can provide secure remote access without exposing their systems to the public internet.
It's crucial to identify where you have RDP exposed, assess that risk, and then make informed decisions to secure your network. If an alternative solution is not immediately feasible, at minimum, follow hardening and security guidelines to minimize potential fallout from an attack.

Frequently Asked Questions
Why is internet-exposed RDP risky?
Internet-exposed RDP is risky because it signals to threat actors that RDP is an essential part of many business processes, making it a prime target. Hackers can exploit vulnerabilities in RDP to gain unauthorized access, and Coalition security research showed that over 37% of all traffic from threat actors in 2022 was RDP-related.
What are the risks of having RDP enabled in the local network?
Enabling RDP in the local network allows connections between computers, providing an easy way for an attacker to perform lateral movements inside your company. Vulnerabilities in RDP, such as BlueKeep, can make computers vulnerable even without valid credentials, allowing attackers to compromise multiple systems.
How can businesses mitigate the risks of internet-exposed RDP?
Businesses can mitigate the risks of internet-exposed RDP by removing RDP from the public internet, implementing Virtual Private Networks (VPNs), utilizing Multi-Factor Authentication (MFA), regularly updating and patching systems, and following hardening and security guidelines to minimize the fallout from potential attacks.
