Dynamics PluginAssembly Read Permission required for Execution - How to protect DLL from download?

(0) ShareShare
ReportReport
Posted on by LR-26031237-0

Hi Community,

we noticed that our end users have Read access on the PluginAssembly entity, which allows them to potentially download and decompile our plugin DLL to access our source code.

When we tried to remove the PluginAssembly Read permission from the user security role, we received the following error during plugin execution:
"Error while trying to get the assembly" ErrorCode: 0x80040224

As soon as we re-added the permission, the error was gone.

Our questions:

  1. Is the PluginAssembly Read permission truly required for plugin execution?

  2. Is there a way to allow plugin execution while preventing end users from downloading the DLL?

Any help or experience with this is greatly appreciated!

Thanks in advance!

    Is PluginAssembly Read required?
    Yes — mandatory for plugin execution
     
    Can you prevent DLL download while allowing execution?
    No — not via security roles or standard configuration
     
    Use best practice strategy
    • Restrict admin/customizer access
    • Use managed solutions
    • Obfuscate assemblies
    • Move critical logic to external APIs
