Recommended CSM roles for internal and external users

Explicit Roles plugin

The Customer Service plugin (com.sn_customerservice) activates the Explicit Roles plugin (com.glide.explicit_roles), which adds the snc_external and snc_internal roles. When the plugin is activated:

• All users must have either the snc_internal role to access internal resources or the snc_external role to access external resources.
• All existing users are automatically assigned the snc_internal role. This role does not change existing access levels or system behavior. Instead, it provides a category to differentiate internal users from external users. All internal users maintain the same level of access as before the plugin was activated.
  Tip: To prevent changing existing functionality for users, activating the Explicit Roles plugin assigns the snc_internal user role to all existing users in the instance, including any external users added before the Explicit Roles plugin was activated. After the Explicit Roles plugin is activated, do the following for all external users added before the Explicit Roles plugin was activated:

  • Remove the snc_internal role.
  • Add the snc_external role.

  This ensures that external users added before activating the Explicit Roles plugin do not have access to internal resource that should be available only to internal users.
• Newly created users are automatically assigned the snc_internal role when they first attempt to log in to the instance, unless they have been explicitly assigned the snc_external role. You can add the snc_external role to a new user before they first log in to the instance to provide external user rights.
  Note: The snc_internal and snc_external roles can be added or removed at any time to change user rights.
• All existing ACLs that do not have a role requirement are automatically assigned the snc_internal role. Because both existing ACLs and roles are assigned the snc_internal role, existing access levels do not change.
• Newly created ACLs that do not have a role requirement are automatically assigned the snc_internal role. This role assignment does not apply to a newly created ACL with a role assigned.
• For all existing Processor [sys_processor] records or newly created Processor [sys_processor] records with Type=script, the snc_internal role is automatically added to the Roles field if the field is empty.
• To restrict access to UI pages to internal users, the plugin automatically assigns the snc_internal role to the * ACL with a Type of ui_page.
• To restrict access to processors to internal users, the plugin automatically assigns the snc_internal role to the * ACL with a Type of processor.
• External users must obtain, at minimum, the snc_external role to access the instance. This role is automatically assigned to external Customer Service Portal contacts. If the Customer Service Portal is not activated, this role must be manually granted to external users. Access to records is granted through ACLs.
  Note: You can use the isPublic() function in scripts for Customer Service Portal to change the privacy setting for a single client-callable script include. For more detail, see Script includes.
• Content Management System site access is also affected. CMS is set up with Sites (content_site), Pages (content_page), and other resources. Some of the sites may have the Login page configured.
  • If CMS sites do not have the Login page configured, the public role is automatically added to the Read Roles field on Pages (content_page) if the field is empty.
  • If CMS sites have the Login page configured, the snc_internal role is automatically added to the Read Roles field on Pages (content_page) if the field is empty.
• Service Portal site access is also affected.
  • The snc_internal role is not automatically added to sp_page, sp_widget or sp_instance records. If desired, you can give new records the role by assigning snc_internal as a default value in the Roles field for these records. For details on this process see Specify a default field value.

Do not move System update sets among instances with and without the Explicit Roles plugin enabled.

The glide.security.explicit_roles.internal_user_blacklist property

The Explicit Roles plugin assumes that all existing users in the sys_user table at the time the plugin is installed are internal customers. A fix script assigns the snc_internal role to all existing users and to any ACL that does not have a role.

The fix script may fail or may not finish in time for a user who has not been updated with the role and who attempts to access a resource. To bridge this potential gap, the Contextual Security Manager (CSM) auto-assigns the snc_internal role to any user who logs in and does not have an explicit role (either internal or external).

Additionally, CSM has a business rule process that assigns the snc_external role to a classification of their users. However, when importing large sets of CSM external customers, workflow is set to false, so business rules don't run. As those users attempt to access a resource, they do not have any explicit roles. The Contextual Security Manager assigns the snc_internal role through a scheduled job called On-Call Gaps Conflicts Report that runs every 7 days. When the Explicit Roles plugin is active, this job assigns the snc_internal role to the CSM external user, since the user does not have either the snc_internal or snc_external role.

To prevent inadvertently providing the snc_internal role to external users, the Explicit Roles plugin includes a glide.security.explicit_roles.internal_user_blacklist property to blacklist user types from ever becoming snc_internal. If there are no users types in the glide.security.explicit_roles.internal_user_blacklist table, the Contextual Security Manager assigns all users the snc_internal role by default. If there are classnames in the blacklist table, and if the sys_user class type is in the blacklist table, CSM assigns the snc_external role. Otherwise, CSM assigns the default snc_internal role as usual.

For Orlando Patch 5 and later releases, this property is disabled by default.

Providing table access to external users

You can Provide external users access to a table by adding a role to the table that inherits the snc_external role.

The hasRoles() method

The hasRoles() method is still available, but is deprecated in the Geneva release. Use the hasRole(role name) method instead.
