Regarding remote access in Windows 10, the secure protocol we want to discuss is Remote Desktop Protocol, or RDP. RDP allows for remote display and input capabilities for network-connected Windows applications running on a server. RDP in Windows 10 uses the RC4 cipher, which is a stream cipher that efficiently encrypts small amounts of information.

Since the release of XP, RDP has been the de facto standard for remote session access for Windows Desktop and Server Operating Systems. At 20 years old, RDP has seen multiple versions, with new capabilities added to mature it as a reliable remote access protocol.Oct 13, 2021

What About Security Through Obscurity?

Some individuals recommend changing the default RDP port to enhance security. While I love the phrase “security through obscurity,” obscurity, or changing the port number in this case, doesn’t provide enough protection to be worthwhile. A port scanner can quickly identify your RDP port, in which case you’ve given yourself more work and not accomplished much. There is nothing wrong with implementing this change. It just doesn’t provide any real security.

What is remote desktop?

Remote Desktop made it possible for users to remotely access and control Windows computers as if they were right in front of them. This was a game-changer for sysadmins. If you had terminal services configured, you could remote into workstations and servers without leaving the comfort of your office chair. While this was not beneficial for our waistlines, it made sysadmins much more efficient in their duties.

How long should a password be for remote desktop?

While the common password complexity recommendations used to be eight characters long with a mixture of uppercase, lowercase, numbers, and symbols, nowadays, that’s not enough. Newer computers can brute force a password with these complexity requirements in just a couple of hours. Some security specialists now recommend passwords have a minimum length of 12 characters with a mixture of uppercase, lowercase, numbers, and symbols. Others suggest even longer passwords. As you increase the password’s length, the time it takes to brute force the password goes up exponentially.

How to secure RDP?

The best solution for securing RDP is to couple it with a virtual desktop solution—such as Citrix or VMware Horizons—that uses single sign-on for user authentication . With a virtual desktop solution, an organization can implement MFA to control access and have better visibility and control over remotely accessible endpoints and the data that they store, process and transmit. This increased visibility and control helps to prevent lateral movement of threats within the network and makes it easier to implement secure remote access.

What is the amplification factor of RDP?

RDP servers are potential DDoS amplifiers with an amplification factor of 85.9. Therefore, attackers can abuse these services to send massive amounts of traffic to their targets, knocking them offline. The growing threat against RDP makes it vital for organizations to install anti-DDoS protections on their Internet-facing systems.

What is a DDoS attack?

In a distributed denial-of-service (DDoS) attack, the goal is to send as much data as possible to a target website or server in order to overwhelm it and knock it offline. DDoS attackers use a variety of different methods for accomplishing this, such as large botnets or a technique called DDoS amplification, which takes advantage of a service that sends a much larger response than the initial request. DDoS attackers will send traffic to these services while masquerading as their target. The target website or server is then flooded with much more data than the attacker sends.
