Ensure that authorization is enabled
HighLevel 1Manual reviewdb2-zos
Description
The AUTH subsystem parameter controls authorization checking in Db2. It is recommended that this parameter is set to YES. Disabling all authorization checking opens all Db2 access to PUBLIC.
How it is checked
Audit method: Manual review
This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.
Run the DSNTEJ6Z job to obtain the current value of the AUTH subsystem parameter. Verify that the value is set to YES.
How it is fixed
Fix method: Guidance or infrastructure patch
1. Edit the DSNTIJUZ job and set the DSN6SPRM.AUTH parameter to YES. 2. Submit DSNTIJUZ to assemble the subsystem parameter. 3. Issue the -SET SYSPARM command or stop and restart Db2 to activate the change.
