Security services are required for almost every activity on the computer in order to protect it from getting attacked by hackers or viruses. Similarly the large data servers and computer networks are also protected by security services that blocks any unwanted activity to take place.
Therefore, I would like to share some important techniques to secure your terminal services so that by no means susceptibility is exploited. Although this is not a comprehensive guide but it will give a fair idea of how to secure your Terminal Service environment.
Deploying Security Services
In order to deploy Security for your servers make sure that the server does not have any second program running along. Although it might be a little difficult for many organizations which are allocated with a limited budget to spend but running two server applications Cctv installation have a negative impact on the server and the Security services being deployed may put a major strain on your server. Therefore in order to cut down the load on your servers and its resources such as the memory of your CPU etc, planning is required so that the services act without any ambiguity.
If terminal services are running on a domain controller then the security risk is increased as it shows clearly that the server is assigned with a double duty configuration. Security services help protect servers and its resources only if it is allowed with a free space and speed. It is obvious that if a user manages to gains access to an operating system of your company and the terminal services are installed in your domain then he can easily get control over your domain and the services may not function properly because of the strain on the server and you are challenged with high security risk because of it.
Another reason of high risk before deploying terminal service is when inappropriate services are being used. Although operating systems are equipped with new versions of Security services whenever the latest version of windows server is installed, but it maintains a backward compatibility which can have an effect on the services. For example, an option of relaxed Security is given whenever Windows Server 2003 version of the terminal services is installed which helps you to maintain a backward compatibility with previously installed windows server. But make sure that the Security of the newer version are working well or your server will be at high risk and hackers can cause damage to your organization by passing through the domain. Similar Security configuration options are given in windows 2000 server to choose between permission compatible with terminal server 4.0 or windows 2000 server users.
Therefore, when upgrading servers, planning is required on what Security mode you shall you switch to. This is because when a mixed environment mode is running on your system few of the applications maintained from an older version might not be compatible with the newer version being deployed. So in order to control situation like this relaxed Security can be used until all the applications on the server are updated to the latest operating system. But once it has been decided to update the servers then the Security services running in the relaxed mode should be reset and switched to full security option to give maximum security to all the applications on the server and prevent any misuse or unauthorized user to gain access.
