Rockwell Automation recommends users of the affected products to take the following actions:

- Disable the web server, if possible (This component is an optional feature and disabling it will not disrupt the intended use of the device)
- Configure firewalls to disallow network communication through HTTP/Port 802
- Upgrade to the MicroLogix 800 or MicroLogix 850 as this device does not have the web server component

Rockwell Automation also recommends users to employ cybersecurity best practices, as outlined in their Knowledgebase article.
