This document provides an overview of security settings and configuration for a Cartegraph OMS site. It discusses creating new users and roles, OMS security settings, layouts, library filters, and using ArcGIS Online to control map access. The document explains that security is managed by roles, how to add new users and roles, customize roles, and add filters to libraries. It also notes that security is a combination of role settings, layout assignments, library filters, and map settings, and that default roles should not be used for production level users.
