iAccess Printer Host-Based Security

Currently QTCP is required to start a Host Based Printer. However, this opens up security that a user can setup a HOST Based printer that allowed them to redirect the HR files. Is it possible to restrict a Host Based Printer from being started unless both QTCP and the User has access to start that printer using an Authorization List.

    IBM has received your Idea and is evaluating it. IBM will provide a response after evaluation is complete however early analysis is an authorization list can't address the concern.

    The telnet protocol for a printer session does not have an associated user profile.  Therefore, it is not possible to use an authorization list to restrict users from starting a printer session for a particular printer device.  The server-side steps for starting a printer session could be modified to prevent ALL printer session from starting a print writer.  Starting the print writer would require a separate action (Start Print Writer (STRPRTWTR) command) using some other authenticated connection (such as a display session).  This disruptive design change would impact print procedures currently in use by customers.  Would you and those following this IDEA run with that restriction in place?
     
    Best practice documentation describing how to protect print output with the existing behavior is being drafted.  The primary mitigation is to create spooled files in an output queue that is not located in the QUSRSYS library.  When these spooled files are to be printed using a printer session, the printer session must be started and then the print writer must be changed to use the output queue where the spooled files are located.  This will enforce that the user changing the print writer is authorized to the output queue and spooled files.
