A typical MS operating system will have the following setting by default as seen in the Local Security Policy:.
Although a password convention to avoid identical local admin passwords on the local machine and tightly controlling access to these passwords or conventions is recommended, using a local admin account to work on a machine remotely does not properly log and identify the user using the system.
It is best to override the local security policy with a Group Policy Setting. Going forward, whenever new machines are added in the OU under the GPO, your settings will be correct. By setting your computer to lock an account for a set number of incorrect guesses, you will help prevent hackers from using automated password guessing tools from gaining access to your system this is known as a "brute-force" attack.
To set an account lockout policy:. Having RDP port open to off campus networks is highly discouraged and is a known vector for many attacks. The options below list ways of improving security while still allowing RDP access to system. Once an RDP gateway has been set up, hosts should be configured to only allow RDP connections from the Gateway host or campus subnets where needed.
Using an RDP Gateway is strongly recommended. It provides a way to tightly restrict access to Remote Desktop ports while supporting remote connections through a single "Gateway" server. When using an RD Gateway server, all Remote Desktop services on your desktop and workstations should be restricted to only allow access only from the RD Gateway. Includes DUO integration. Dedicated Gateway Service Managed. Needed for rdp access to systems that are UC P4 or higher. A rough estimate might be that concurrent users can use one RD Gateway.
The HA at the virtual layer provides enough fault-tolerant and reliable access; however a slightly more sophisticated RD gateway implementation can be done with network load balancing. Changing the listening port will help to "hide" Remote Desktop from hackers who are scanning the network for computers listening on the default Remote Desktop port TCP This offers effective protection against the latest RDP worms such, as Morto.
Change the listening port from to something else and remember to update any firewall rules with the new port. Although this approach is helpful, it is security by obscurity, which is not the most reliable security approach.
You should ensure that you are also using other methods to tighten down access as described in this article. Using other components like VNC or PCAnywhere is not recommended because they may not log in a fashion that is auditable or protected. Since there are a variety of ways to attempt to secure RDS or secure RDP , below is a table that shows common methods of securing Microsoft Remote Desktop systems, and their drawbacks.
Placing a Windows system with the RDS port open to the Internet is the equivalent of placing a Windows computer in a public place so that anyone can try to login to it. In fact, it is worse since anyone on the internet can attempt to login.
Exposing a Windows system running RDS to the internet in this manner exposes it to the possibility of a denial-of-service attack; data theft; and data compromise. Place behind firewall and restrict external access to trusted IP addresses.
It is not a good solution for supporting people working from locations that do not have fixed IP addresses. It limits the ability to work from public locations with untrusted, even if fixed IP addresses. There is a need to constantly verify that trusted IP addresses can continue to be trusted. It is not an effective way to support remote access to several Windows RDS systems in a centralized location due to need to secure one IP address for each Windows system.
This login page is not much more secure than exposing each Windows RDS system directly to the internet for random login attempts or with stolen credentials. Moreover, with malicious intent and adequate preparation and resource, MFAs that rely on SMS messages can be compromised. This is an effective but complex solution to implement. A VPN gateway can be subjected to denial-of-service attacks. TruGrid is the simplest and most effective way to secure a Windows RDS environment for the following reasons:.
TruGrid includes fully-integrated security and cloud scalability and can be implemented in minutes. TruGrid simplifies Access and Device Security for organizations by reducing complexity and associated costs.
