since you (anyone with update authority) can change the user id attribute of a member of a pds to virtually anything
via the ISPF option 3.5
it is a waste of time to expect any type of control over pds's via the user id.

virtual machine to

what do that mean?
either someone has mainframe access (via internet, direct hard connection, whatever)
or someone does not.

PDS statistics, including user id, are generated and maintained by ISPF within TSO. If you don't use ISPF to update the PDS member, then most likely the user id that made the change would not be recorded -- no matter where the changes came from.

And unless you -- or someone -- analyzes the SMF data (which in itself is NOT a trivial task unless your site uses one of the SMF analysis tools such as MXG), it is not possible in general to know if someone changed a PDS member. If this is a concern of yours, you need to talk to your site security group about restricting access to that PDS. When there's a good business reason for doing so, site security groups usually have no problems with making such changes.

As far as security is concerned it is a bad way

I have seen places where the last modified person gets all bashing (Which was against his knowledge) for some bad codes written initially created by him or her as reviewer would blindly by userid

Why bother who did this / that when they cant modify?

Just a thought
