## Profile Applicability

- Level 1

## Description

WorkSpaces access should be restricted to trusted operating systems and clients.

## Rationale

WorkSpaces access is supported from a variety of clients and operating systems, including HTML5 based browsers. Disabling Web Access prevents access to the Workspace from HTML5 based browsers, ensuring access can only occur from known operating systems.
