What is remote desktop service?
Remote Desktop Services are being used not only by employees for remote access, but also by many system developers and administrators to manage cloud and on-premises systems and applications. Allowing administrative access of server and cloud systems directly through RDP elevates the risk because the accounts used for these purposes usually have higher levels of access across systems and environments, including system administrator access. Microsoft Azure helps system administrators to securely access systems using Network Security Groups and Azure Policies. Azure Security Center further enhances secure remote administration of cloud services by allowing “just in time” (JIT) access for administrators.
What is the default port for remote desktop services?
Firewall rules may be labeled as “Remote Desktop” or “Terminal Services.”. The default port for Remote Desktop Services is TCP 3389, but sometimes an alternate port of TCP 3388 might be used if the default configuration has been changed.
Do on premises deployments have to consider performance and service accessibility?
On-premises deployments may still have to consider performance and service accessibility depending on internet connectivity provided through the corporate internet connection, as well as the management and maintenance of systems that remain within the physical network.
Is remote desktop service secure?
Although Remote Desktop Services (RDS) can be a fast way to enable remote access for employees, there are a number of security challenges that need to be considered before using this as a remote access strategy. One of these challenges is that attackers continue to target the RDP and service, putting corporate networks, systems, and data at risk ( e.g., cybercriminals could exploit the protocol to establish a foothold on the network, install ransomware on systems, or take other malicious actions). In addition, there are challenges with being able to configure security for RDP sufficiently, to restrict a cybercriminal from moving laterally and compromising data.
