A device no longer receives updates from its original maker. Which measure addresses the risk of keeping this device active in a production environment?
Relocate it to an isolated subnet with minimal security review
Restrict usage hours but continue to implement routine patches from third parties
Plan a timeline to remove it from active use and transition to a supported alternative
Download archived updates from past releases and deploy them as needed
When an item is out of support, vulnerabilities no longer receive official fixes. Formally planning its retirement or replacement ensures updated security features and reduced operational risks. Other methods, such as relying on outdated firmware, limiting usage, or suspending rigorous checks, do not address fundamental gaps that arise when the original maker stops patching flaws.
