gNB DU is the one deployed close or along with the Radio Unit. UEs always interfaced with Radio Unit through air interface and Radio Units are connected gNB DU.

DU as name suggests is distributed units, there could be more than one distributed units deployed and they talk to Central Unit(CU).
CU and DU communicate using and interface called F1.

In CU-DU architecture, how user plane data is going to flow ?

I was going through the security specification of 5G network and stopped at a point where it was mentioned that UE shall support integrity protection of user data along with the integrity protection of RRC and NAS-Signalling. Section 5.1.3.1 also mentions that integrity protection of the user data between UE and gNB is optional to use.
I want to know that for which cases/scenarios, it would be needed to enable integrity protection for user data between UE and gNB ?
Enabling both integrity and ciphering for the user data would be an overhead, therefore I started thinking about scenarios/cases.
