You can analyze LSM, it seems to be a good solution. ([1]).

From what I have read, with LSM you have to provide a full solution because it does not allow you to stack modules[1]. This also means that my module will not work with SELinux or other LSM modules. I only need a subset of LSM hooks. 

I can use LSM, but I want to know if there is another solution.

Then you have to write your own hooks apart from LSM! Even a complete solution is not difficult but might take a bit longer to implement the unused hooks with just return 0;
