Remote Desktop Service – Advice for Improving Security NLA forces the client computer to present user credentials for authentication before the server will create a session for that user.Īs session creation is relatively resource intensive, NLA provides a layer of defence against Denial of Service attacks whereby a malicious user makes repeated connections to the service to prevent its legitimate use by others. Terminal Servers which support Network Level Authentication (NLA) but do not have it configured present a risk. Denial of Service (Network Level Authentication) The medium setting may facilitate the use of weak encryption which could be decrypted in a reasonable time-frame and lead to the disclosure of sensitive information. It’s generally used in an environment containing mixed or earlier-version clients. This level of encryption encrypts data sent between the client and the server at the maximum key strength supported by the client. Encryption Attacksīy default, the Remote Desktop service uses an encryption setting of Client Compatible (medium). Thankfully however the decryption of even medium level encryption is beyond the capability of most casual attackers.
Similar attacks could be made to capture encrypted RDS traffic. If such conditions are met, tools such as Cain and Abel (i) are freely available and trivial to use to perform MiTM attacks and compromise Remote Desktop protocol. Typically, this requires the criminal to perform other attacks such as ARP (Address Resolution Protocol) spoofing or DNS (Domain Name System) spoofing, which redirect connections to the attacker prior to sending the data to the legitimate server.
The likelihood of this type of attack depends on a hacker’s ability to control connections between the client and the Terminal Server.

This lack of identity verification allows a malicious person, by deploying other nefarious activities, to intercept all communications sent between a client and a Terminal Server. Man-in-the Middle Attacks (MiTM)Īlthough the Remote Desktop service provides data encryption between the client and server by default, it doesn’t provide authentication for verifying the identity of the Terminal Server.

If a password is guessed successfully, the resulting access could have substantial repercussions for your organisation and facilitate further attacks against trusted or connected infrastructure. By default, the first account an attacker would try is ‘Administrator’ which is not usually configured with an account lockout. Worse still, malicious Internet based attackers could carry out brute force attacks against the service. There is no necessity to expose the Remote Desktop service to the Internet, thus enabling untrusted users on the Internet to attempt connections. In its default state, a Windows server will only allow Administrator-level users to log in to the host via the service. RDS typically allows for remote administration of systems by support personnel.
Security flaws and misconfigurations can render a Remote Desktop service vulnerable to the following attacks: RDS Exposed on the Internet It equips a user with a high degree of usability and accessibility by enabling the remote control of a computer, client or virtual machine over a network connection ( i), commonly over a graphical user interface. Remote Desktop service (RDS), known as Terminal Services in Windows Server 2008 and earlier, is a component of Microsoft Windows.
