Why a permission to a region acid of a started task does only take effect when it is paused and then started again?
The CA Top Secret command: TSS REFRESH of the acid does not seem to work.
The issue will be issue, if a end-user application uses the region Acid to do security check at task level.
I.e. create a security environment for a TCB (Task Control Block). In other words performs a sign-on and anchors the ACEE address to the TCBSENV field.
When a security call occurs without a security environment passed along, CA Top Secret searches for a security environment to make this validation.
To do this CA Top Secret:
- First checks whether there is a security environment at task level.
- If it doesn't exist, CA Top Secret will check the region level.
And here, there is a security environment at task (TCB) level. So CA Top Secret used it to make the validation regardless of the security environment at region level.
Generally when you modify an acid security environment, i.e. giving or removing authorization, you can use the TSS REFRESH command to make the changes effective immediately.
In this case, it doesn't work because TSS REFRESH doesn't scan the TCBs. CA Top Secret only scan the security environment at the region (Address space) level and its "security environment cross table" in a multi users region to refresh acid. The REFRESH command also works for 3rd-party racheck.
If this TCB doesn't have a security environment, CA Top Secret will take the region security environment to make the validation and it would work.
