The Real Security Behind Microsoft Remote Desktop: Myths, Facts and Best Practices

With the increasing prevalence of remote work, ensuring the security of remote desktop connections has never been more critical. Microsoft Remote Desktop Protocol (RDP) is widely used for accessing remote systems, but its security is often questioned. How secure is Microsoft Remote Desktop and most importantly is it secure enough for your business? In this article, we will debunk common myths, present factual security assessments and provide actionable best practices to secure your Microsoft Remote Desktop. By the end, you'll have a clear understanding of how to protect your organization from potential threats thanks to RDS-Tools Advanced Security.

Short Reminder about Microsoft Remote Desktop

Microsoft Remote Desktop allows users to connect to a remote computer and interact with its desktop environment as if they were physically present. It provides a full desktop experience, including remote sound, clipboard access and file transfers, over a network connection. This capability has made RDP a popular tool for IT management, remote work and technical support. However, its widespread use also makes it a target for cyberattacks.

1Debunking Common Myths about RDP Security

Myth 1: "RDP is inherently secure because it's a Microsoft product."

While Microsoft has implemented several security features in RDP, it is not inherently secure out-of-the-box. The default settings provide a baseline level of encryption and security, but these are not sufficient to protect against advanced cyber threats. It is crucial to configure additional security measures to enhance the protection of RDP.

Myth 2: "Firewalls alone can protect RDP from cyberattacks."

Firewalls are an essential component of network security, but they only do part of the work and are therefore not foolproof. RDP traffic can be encrypted thus appearing legitimate. Hence the difficulty for firewalls to detect malicious activity. Additionally, firewalls cannot protect against internal threats or compromised credentials. Relying solely on firewalls leaves gaps in your security strategy.

Myth 3: "Regular updates are enough to keep RDP secure."

While keeping your systems updated is vital, it is again not a standalone solution. Updates patch known vulnerabilities, yet new threats are constantly emerging. A comprehensive security strategy involves multiple layers of protection, including strong authentication methods, access controls and continuous monitoring.

2: The Facts: Understanding RDP Vulnerabilities

Known Vulnerabilities of Microsoft Remote Desktop

- Exposed RDP Ports are the main inroad for most of the threats listed here. Over the years, warning has been given repeatedly regarding this simple set-up fact.

- BlueKeep (CVE-2019-0708): This vulnerability affects older versions of Windows and can be exploited to execute arbitrary code remotely. Despite being patched, many systems remain unprotected.

- DejaBlue (CVE-2019-1181 & CVE-2019-1182): Similar to BlueKeep, DejaBlue allows remote code execution due to an integer overflow in the RDP server’s dynamic link libraries. These vulnerabilities highlight the need for timely updates and patches.

Some Other Common Risks

- Man-in-the-Middle Attacks: Without proper encryption, attackers can intercept and manipulate RDP traffic. This done, they can then impersonate the chosen party.

- Brute-Force Attacks: RDP servers exposed to the internet are often targeted by automated tools attempting to guess passwords.

- Ransomware: Exploiting RDP vulnerabilities is a common method for deploying ransomware within an organization’s network. WannaCry and other ransomware have also caused havoc for businesses and their data and infrastructure.

3: Best Practice for Enhancing RDP Security

* Network Level Authentication (NLA) and Multi-Factor Authentication (MFA)

Enabling NLA ensures that the user is authenticated before establishing an RDP session, reducing the risk of unauthorized access. 2FA or MFA adds an additional layer of security by requiring a second form of verification, such as a mobile app or hardware token.

* Regular Updates and Patches

Ensure that all RDP clients and servers are updated with the latest security patches. This practice mitigates the risk of exploitation through known vulnerabilities such as BlueKeep and DejaBlue.

* Strong Password Policies

Implement policies that require complex passwords, regular password changes and account lockout after multiple failed login attempts. This approach helps prevent brute-force attacks.

* Disable Unnecessary Features

Turn off features like clipboard and printer redirection unless they are essential for your operations. These features can be exploited to transfer malicious data or exfiltrate sensitive information.

* Restrict RDP Access

Limit RDP access to necessary user accounts, situations, times etc. plus avoid using default admin accounts. Implement role-based access control (RBAC) to ensure that users only have the permissions they need to perform their tasks.

4: Advanced Security: Simple Efficient Affordable Measures

* Configuring a Microsoft RDS Gateway

Using an RDS Gateway enhances security by tunnelling RDP sessions through HTTPS. This configuration provides an additional layer of encryption and hides RDP servers from direct exposure to the internet.

* Secure Alternatives: RDS-Tools

RDS Tools Advanced Security offers all-round security for traditional RDP with advanced features ranging from:

• integrated firewall;
• automatic known malicious IP blocking;
• through anti-malware protection;
