Hi everyone!I am looking for a good reference to secure a Citrix server to avoid a user to gain acces to the operating system. So far I have some ideas like restricting the execution of the cmd.exe and (maybe) explorer.exe from with a group policy in the domain.If you know about any document I can look at or have any experience about this that want to share I will be very thankful. Thanks in advance.
Which Citrix products are you interested in? Citrix solutions are quite powerful and complex, therefore understanding and securing them is not an easy task. Here are some resources about securely deploying Citrix XenApp, Citrix XenServer, and Citrix Access Gateway:
