This probably a rather naive question given my limited knowledge in the code I've been looking at, but I want to get my head around it before I start diving into writing actual code myself.
I'm writing a common set of tools for PHP and most of my inspiration has come from the .NET framework. The ironic thing is that I have never used the .NET framework, but I do understand C# and can therefore port the concepts I "do" understand from Mono.
But I have run into a bit of a wall,
System.Security. As I browse over the API docs, and the Mono security implementations on Github, I quickly feel like none of features could ever be applied to PHP. My current confusion is as follows:
PermissionSet ps1 = new PermissionSet(PermissionState.None);
So here is a basic example. What I want to do in PHP is create an application partially governed by permissions on the "environment" level. That is to say, one machine shouldn't be able to perform certain actions that another might. For instance, machine A, shouldn't be allowed to TCP to machine B.
But when I look at the code in the example, I don't really understand why it makes any difference. My current understanding is that this is not "setting" the permissions, but "checking" them. And the permission itself is predefined somewhere else, I.E. in the machine.
I have looked over Java's implementation of the same feature, and side by side .NET looks a lot more in-depth. I would like to incorporate this concept into my own PHP code, but right now I don't know how I would do it.
Are the permissions entirely arbitary? does .NET "impose" restrictions? or simply provide security diagnostics to the application? If the last one is true, then porting to PHP is not only possible, but may actually be quite useful. However I know that in PHP, the second one is impossible.
Could someone please clear up what the Java and .NET security namespaces do, and give me an idea of how feasible it is to port to other languages.
