# Sandbox Policies This directory integrates the lower-level core sandboxing library with the [`//content`](../../content/README.md), [`//services`](../../services/README.md), and [`//chrome`](../../chrome/README.md) layers. It provides concrete security policies for specific process types and Mojo services, whereas the library provided by `//sandbox` is a generic sandboxing primitive. Code in this directory (or other directories) may freely depend on code in the core `//sandbox` library, but the `//sandbox/{mac,linux,win}` directories may not depend on this policy component.
