A manufacturing facility discovers that a key server platform no longer receives vendor support or security updates, and attackers have begun exploiting known flaws. Which action best addresses the security risk?
Upgrade the platform to a related version actively maintained by the vendor
Reinstall the same software set in an effort to remove hidden threats
Focus on reviewing system logs on a frequent schedule
Place the server on a network segment to limit outside scanning attempts
Upgrading to a supported version removes the root cause, which is a lack of ongoing fixes for new exploits. Placing the system on a network segment or monitoring logs can add defensive layers, but vulnerabilities still remain unresolved. Reinstalling old software can reinstate the original risks, so it does not address the core issue.
