A healthcare group uses older operating systems on various machines across its facilities. The staff wants to keep medical processes going and reduce the threat from malicious code exploiting known vulnerabilities on these systems. Which measure meets these requirements?
Introduce extra training sessions for personnel
Schedule recurring operating system patch installations
Establish a system that approves which programs run on each device
Enforce multi-factor access for all healthcare staff
Establishing a system that approves which programs run helps prevent unauthorized software from executing on devices that lack patching options. Multi-factor access is beneficial for user verification but does not stop harmful processes. Training is important but does not neutralize code that runs without detection. Scheduling daily patches is not an option if the systems cannot receive updates from the vendor. Limiting which programs run protects these machines from most new exploits by blocking unapproved executables.
