Update to the Enhanced 3270 User Interface Security Requirements

December 17, 2013 Leave a comment

In this post I mentioned that the recent OB700 IF1 update had added additional security checking for KOBASE and 04SRV resources and that without suitable RACF (or other security product) profiles to give the user read access to these  resources, users would not be able to log on to the Enhanced 3270 UI.

PTF UA71750 is now available and removes the security checking on these resources. As a result, these additional security profiles are no longer required.

 

Securing the Enhanced 3270 User Interface with RACF and OB 700 IF1

October 16, 2013 2 comments

In this post I talked about securing the enhanced 3270 User Interface with RACF

Since then a new level of the base code (FMID HKOB700) called Interim Feature One (IF1) has arrived in the form of PTF UA69877. But before you go off and apply that, don’t! Instead apply UA70618 which fixes some issues with the original code that may impact certain users.

In the hold doc (you do read all the hold doc don’t you!) for UA70618 are instructions on setting up new RACF profiles that may be needed if you are using security to protect the Enhanced 3270 User Interface environment. These are the new resources being checked:

KOBUI.USER.COMMAND.<command_name>                               
KOBUI.ADMIN.PREFS.AUTOUPDATE                                    
KOBUI.ADMIN.LISTUSERS                                           
KOBUI.ADMIN.TRACE.UI.<trace_type>                               
KOBUI.ADMIN.TRACE.INTERNAL.<trace_type>                         
KOBUI.ADMIN.USEHUB.<hub_name>                                   
KOBUI.ADMIN.MEMBER.WRITE.<dd_name>.<member_name>                
KOBUI.ADMIN.ITM.<hub_name>.SERVICEINDEX                         
KOBUI.ADMIN.ITM.<hub_name>.<servicepoint_name>.SERVICECONSOLE   
KOBUI.ADMIN.ITM.<hub_name>.<servicepoint_name>.SOAPCONSOLE      
SYSTEM.<managed_system_name>.<table_name>

You could protect these with the following RACF profiles:

PERMIT KOBUI.USER.** 
PERMIT KOBUI.ADMIN.**
PERMIT SYSTEM.**

Recently I came across a problem where a customer needed additional RACF profiles setting up  in order to log on to the Enhanced 3270 UI. These are:

KOBASE.**
O4SRV.**

The easiest way to add these would be with a UACC or READ but your installation standards may require a different implementation. I believe a tech note will be forthcoming on the issue soon.

This particular user had a default profile of * in the RACF class with a UACC of NONE so anything that was not specifically permitted was rejected. If you do not have such a profile in the RACF class used by the Enhanced 3270 UI then the default action is to allow the request if a profile does not exist which basically allows anyone to do anything unless you specifically lock it down. That approach results in the least amount of work to secure the Enhanced 3270 UI environment.
