Require QIBM_DB_SECADM or similar to perform set session authorization

Today any user with *ALLOBJ is able to do the equivalent to sudo in Linux without the need of any password to become another user using set session authorization via SQL. Any user with *ALLOBJ can become Qsecofr by open strsql and run: “Set session authorization Qsecofr”. I propose that only users with special authorization QIBM_DB_SECADM or similar would be able to do this, at least for elevated users.

    IBM does not intend to provide a solution to this Idea at this time, so it is being closed.

    SET SESSION AUTHORIZATION is an SQL statement that swaps the effective user of the current thread to be running as a different user.
    Documentation: https://www.ibm.com/docs/en/i/7.5?topic=statements-set-session-authorization
    The SET SESSION AUTHORIZATION requires *ALLOBJ special authority, and an AF-K audit journal entry is generated if a user without *ALLOBJ attempts to use it.
    The SQL statement is implemented via calls to QSYGETPH (using Password_NOPWDCHK) and QWTSETP.

    ? Get Profile Handle (QSYGETPH) validates a user ID and password, and creates an encrypted abbreviation called a profile handle for that user profile.
    ? Set Profile Handle (QWTSETP, QsySetToProfileHandle) switches the job to run under a new profile.
    *NOPWDCHK:
    - The user requesting the profile handle must have *USE authority to the user profile.
    - If the profile is disabled, the user requesting the profile handle must have *ALLOBJ and *SECADM special authorities to get a handle.
    - If the password is expired, the user requesting the profile handle must have *ALLOBJ and *SECADM special authorities to get a handle.

    SET SESSION AUTHORIZATION and Set Profile Handle have a common security authorization requirement, which always includes *ALLOBJ, and sometimes includes *SECADM.
    To add an additional function usage authorization requirement to one of the interfaces would create a chasm in security implementation.
    Such an additional requirement to security would also likely break many existing software vendor products and customer solutions.
    It is for these reasons that the IBM i security team and Db2 for i team are rejecting this idea.

    The CAAC has reviewed this IBM Idea and recommends that IBM view this as a high priority Idea that is important to be addressed. From a security perspective, this is a valid request.


    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual IBM Ideas on the broader IBM i community, and has therefore reviewed your Idea.

    The CEAC agrees with the sentiment of this idea but would suggest that any user with this concern looks to remove all unnecessary users with *ALLOBJ authority. IBM added Authority Collection Services in IBM i 7.3 to assist with this process.a
