Isolating the component is the best immediate mitigation strategy because it minimizes the chances of an attacker reaching and exploiting the outdated system. Once isolated, the business can plan for a replacement or upgrade. Patching is not an option since the vendor no longer supports the software. Increasing monitoring or relying on AI-based security solutions are valuable strategies but do not directly mitigate the risk associated with the use of end-of-life or outdated components.
