A factory-floor system uses critical, legacy, and unsupported application software to enable factory operations. A latent vulnerability was recently exposed, which permitted attackers to send a specific string of characters followed by arbitrary code for execution. Patches are unavailable, as the manufacturer is no longer in business. Which of the following would be the BEST approach the company should take to mitigate the risk of this vulnerability and other latent vulnerability exploits?
(Choose two.)
A. Configure a host-based firewall on the application server and restrict access to necessary ports and services.
B. Create a factory-floor enclave segregated from direct LAN/WAN reachability.
C. Implement a proxy that will sanitize input provided to the application.
D. Install server-side X.509 certificates and enable TLS 1.0 or later for client access.
E. Install network and host-based IDS, feeding logs to SIEM, and alerts to SOC operators.
F. Create a hunt team focused on the factory-floor operations.
