For the first issue: Create a system user with the same name as application Y. Change the ownership of file X and application Y to this system user. Chng the file permissions of the file X to 600 with chmod. And enable the setuid bit of the application Y also with chmod.
For the second issue: If application Y runs as root user then it will get all the rights to access all the files including file X.

Sir, I am trying to solve a problem wherein I would like to give (read, write) access to file X, if it is accessed by only application Y and again if the application Y is invoked by root user. I have gone through the documentation of Apparmor, seccomp etc. But not able to find solution to the problem I am trying to solve. If you can suggest me a tool or api or library that will help me to solve my problem, it will be great. Your guidance is vital to me. Waiting for your reply. I apologize for the disturbance.
