Issue/Introduction

When navigating the Integrated Cyber Defense Manager (ICDM), some of the tabs open up to blank pages. OpenDNS is notably being used in the environment. If OpenDNS is disabled, the impacted tabs load properly.

Script errors seen within the browser's development tools show that there are errors with the Content Security Policy we use for the website.

Environment

Impacted browsers:
Chrome
Firefox

Impacted iCDM tabs:
My Tasks
Investigate
Devices
Discovered Items
Incident and Alerts
Reports and Templates
Quick Setup
Settings

Resolution

Broadcom does not support proxied traffic to the ICDM site. The ICDM Console uses a strict Content Security Policy and is working by design.

The tabs may load properly with the latest Edge Chromium browser while OpenDNS is used.
