Hi Ajay,
I hope that I have understood you well.
First, you must know that IMPERVA has been built based on Role-Based Access Control (RBAC). You can go on GUI to the Admin menu -> Users and Roles, and there you can create the new role for your user who should work only with MIS_Restricted logs.
Second, you cannot customize GUI. But, I have an idea for you. You can use "DB Audit Data" to prepare your report definition. On the menu, you can find the diskette icon, and when you click on it, the report will save on Reports -> Manage Reports. You can permit users to access any specific audit report. Maybe it will be looking not very well like on GUI, but it will be something, not nothing, and the goal will be achieved by you.
and Thirdly - I think you can do it on few method. Firest go to Setup -> Global Objects -> generic dictionary groups.

After that please create the new security policy.

And you have to test it. Would you please give feedback if it will be working well? If not, please write, I give you another way.
