Preventing an application from being started from another computer

[Dennis C. Drumm]

Is there a way to set the security for a .net application so that it can
only be run on the machine were it is installed?

I would like to prevent users from being able to start the application by
navigating to a shared drive on the computer where the program was installed
and starting it using the shortcut or exe installed on the host computer.

thanks,

Dennis

Dennis,

You should be able to apply the ZoneIdentityPermission attribute to the
entry point of your application. You can pass the MyComputer value from the
SecurityZone enumeration to the constructor of the attribute. Once you do
that, your application should only run when executed from the local machine.

Hope this helps.

Hi Dennis,

Maybe you could write something to the registry during installation. When
the user tries to start the application from another system it won't find
this registry entry and fail. There might be better ways though.

Happy coding!

That sounds like it would work, but after doing some reading, the how of it
still escapes me! I will keep at it, but if you could provide a little more
information or an article that discusses this issue it would be greatly
appreciated.

Hi Dennis,

Thank you for posting in the community!

Just as Nicholas's solution, you need just apply the
ZoneIdentityPermissionAttribute to the entire assembly like this:
[assembly:ZoneIdentityPermissionAttribute(SecurityA ction.RequestMinimum
,Zone=SecurityZone.MyComputer)]

======================================
Please apply my suggestion above and let me know if it helps resolve your
problem.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.

Thanks, that is what I needed.

I'm still a little confused by the syntax though. The MSDN
documentation for the ZoneIdentityPermissionAttribute constructor only
takes one argument. The ", Zone = SecurityZone.MyComputer" in the argument
list is hanging me up.

Could you explain what is going on here. (I know this will probably turn out
to be embarrassing!)

Thanks,

Dennis

Hi Dennis,

Thanks very much for your feedback.

I am glad it works. :-)

Actually, for an attribute, the first is the constructor of the attribute,
while the following fields are its properties.

If you have any further concern, please feel free to post, we will help
you. thanks.
