Have others removed any roles from the ITIL role? (example: snc_platform_rest_api_access')

[GoBucks]

The ITIL role is a powerful role.  Out-of-the-box it actually contains MANY other roles as documented here:

https://www.servicenow.com/docs/r/platform-administration/user-administration/r_BaseSystemRoles.html

Has anyone chosen to remove some of those underlying roles from the ITIL role?

In particular, the one that concerns us is the snc_platform_rest_api_access role.  Does an ITIL user who is only ever in the UI really need this role?

My concern is that this role allows for any ITIL user to be able to interact with the platform external to the UI via APIs.  The description on the snc_platform_rest_api_access role states:

Allows access to Platform Rest APIs
- Table API
- Import Set API
- Aggregate API
- Attachment API

Is it safe to remove this role from the ITIL role?  I just don't know if this is inherent to underlying functionality the user needs within the UI, OR, is this for hitting API endpoints external to the UI? (the latter is what we don't want to grant to all our ITIL users.)

Hi @GoBucks ,

I think it is just replacing the role rest_service and they would have included it with itil role so that the users don't have to provide this role explicitly to the integration accounts. as opposed to the rest_service which needed to be granted explicitly as it was not contained by any other roles and most of the organizations use the SSO and users might not be aware of their password and they won't use their password to call the APIs this could be the reason they would add it to itil

Please mark my answer as helpful/correct if it resolves your query.

snc_platform_rest_api_access role provides user access to all the Platform REST APIs.

If you remove mentioned role from ITIL , it means itil user would not be able to use the Rest API like Table API, import set API  any more.

Note:  Check whether Mid server user having snc_platform_rest_api_access role post removing it from itil. otherwise mid server functionality would be impacted.

Hi @GoBucks 

I'd suggest that removing one role from ITIL isn't the best way to approach this.

From a security, governance, and zero-trust perspective, it's better to only assign the ITIL role to those who absolutely need it, and assign a different role, or create a new (more restrictive) role for others who don't need full ITIL access.

Abusing API access is just one of many ways someone with the ITIL role could cause problems.
