How to protect some files

Question

Hello,

I am developing a small application in C#, and I am looking to protect files so that they are not editable by users except for the application.
I had thought of making a zip with password for the affected files, but could there not be some other more secure and optimal way to protect files?
If so, which ones (with code examples please)?

Thanks.

Answer 1

The windows security model is based on user identity, not applications.

Consider using encryption for application data so that security is tied to the application, not the identity of the user that is running it.

Hi speed780,
>>so that they are not editable by users except for the application.
As RLWA32 said, the Windows security model is based on user identity, not application.
The basic Microsoft Windows security model focuses on two areas: authentication and access control.
In other words, the access control in Windows allows applications to selectively grant or deny certain users access to specific services.
You can also use any access control list to grant or deny specific permissions to specific users or user groups.
More details you can refer to this document.
