Workspace Db2 for z/OS

DENY Remote Connetions to DB2 if not from a permitted combination of System AuthId and Location/IPAddress with wildcarding

Running DB2 11 NFM.

We are trying to ALLOW a remote connection to DB2 on z/OS from ONLY specific combinations of User ID and IP Address via a DB2 mechanism that can be modified dynamically.

Simply looking for a way to DENY a connection from remote IP Address or IP Address range if not using a specific User ID that was intended for use from that IP Address range.

Wildcarding the selection criteria would be needed as well to cover an IP Address range.

I am trying to use functionality available within DB2 for this and can not seem to find a way to accomplish this.

I have considered using:

Roles and Trusted Context - no wildcarding, if no match would still get a 'normal' connection rather than deny the connection. Could we perhaps add keywords to the Trusted Context definition to DENY if no match found rather than getting a 'normal' connection.

Monitoring Connections using Profiles - does allow wildcarding, no control to DENY a connection if no match found.

Resource Limit Facility - no wildcarding, only works for some Dynamic SQL. No direct control to DENY a connection so would need to set ZERO Service Units somehow for the ID if no matching 'specific' rows found using ID and IP combination.

Thanks for your consideration.

    Thank you for submitting this enhancement request. Db2 for zOS development reviewed it and determine the requested capability is already supported in the z/OS Security Server using the SERVAUTH class.

    Sincerely,

    Db2 for z/OS development
