By assigning\nscopes to a reference list, you can control which users and resources (for example,\nrules and UDM search instances) can access and utilize it.\n\nTo understand how data RBAC works, see [Overview of Data RBAC](/chronicle/docs/administration/datarbac-overview).\n\nAdd scopes to reference list\n\nTo add scopes to a reference list, you must have access to all the scopes that\nyou intend to add. You cannot add scopes that you don't have access to.\n\nData RBAC impacts reference lists in the following ways:\n\n- **Data RBAC is enabled *before* assigning scopes to reference lists:** all existing\n reference lists are automatically assigned global scope. Assign\n scopes to each reference list according to your data access control requirement.\n\n- **Data RBAC is enabled *after* assigning scopes to reference lists**: scoped\n reference lists operate on ingested data according to their defined scopes, even\n before data RBAC is enabled.\n\nA scoped user and a global user have different access permissions, with the\nfollowing variation:\n\n- A scoped user can create a scoped reference list with all or a subset of\n scopes that are assigned to them.\n\n- A global user can create either an unscoped reference list (a reference list\n that all the users can use) or a scoped reference list.\n\nTo add scopes to a reference list, do the following:\n\n1. [Log in to Google Security Operations](/chronicle/docs/log-in-to-ui).\n\n2. Click **Detection** \\\u003e **Lists**.\n\n3. In the **List manager** window, select the list that you want to add scopes\n to.\n\n4. In the **Details** tab, in the **Scope assignment** menu, select all the\n scopes that the reference list must have access to.\n\n5. Click **Save edits**.\n\nThe scopes are added to the reference list.\n\nUpdate scopes in a reference list\n\nTo update the scopes in a reference list, you must have access to all the data\nscopes that you intend to add to the reference list. You cannot add scopes that\nyou don't have access to.\n\nThe following considerations apply when updating a reference list:\n\n- Removing scopes from a reference list is allowed only if all the existing\n rules that use the reference list stay functional with the change.\n\n For example, an update for a reference list from scopes A and B to scope A\n is not allowed if a rule with scope B uses the reference list. Similarly,\n an update for a reference list from being unscoped to scope A is not allowed\n if a rule with scope B uses the reference list.\n- A scoped user can remove a scope from a reference list which can cause\n another scoped user to lose access to the reference list.\n\n For example, a user with scopes A and B can remove scope B from a reference\n list with scopes A and B. After this change, the user can still use the\n reference list, but another user with only scope B can no longer view or\n access the reference list.\n- Updating scopes to add more scopes can cause some users to lose their edit\n access to the reference list.\n\n For example, a user with scopes A and B can add scope B to a reference list\n that has scope A. After this change, the user can still edit the reference\n list, but another user with only scope A is no longer able to edit the\n reference list.\n\nTo update the scopes in a reference list, do the following:\n\n1. [Log in to Google Security Operations](/chronicle/docs/log-in-to-ui).\n\n2. Click **Detection** \\\u003e **Lists**.\n\n3. In the **List manager** window, select the list that you want to add scopes to.\n\n4. In the **Details** tab, in the **Scope assignment** menu, select all the\n scopes that the reference list should have access to. Deselect the scopes that\n the reference list shouldn't have access to.\n\n5. Click **Save edits**.\n\nThe scope assignment of the reference list is updated.\n\n**Need more help?** [Get answers from Community members and Google SecOps professionals.](https://security.googlecloudcommunity.com/google-security-operations-2)"]]
