A transit administrator oversees older equipment used to manage an automated track system. Reports indicate infiltration attempts from an external source. The team needs to keep the equipment running while stopping unauthorized activities. Which option is the best approach to meet this goal?
Schedule a lengthy shutdown to replace legacy components with modern devices
Establish distinct network segments for the older system and leverage specialized gateways
Elevate administrative permissions so personnel can react whenever suspicious events occur
Apply security updates and shut all remote interfaces to prevent external traffic
Segmentation with monitored gateways helps limit infiltration attempts. Disabling external connections could block valid maintenance processes. A major hardware replacement may cause significant downtime and might not address all vulnerabilities. Granting broad privileges to administrators can weaken security. Segmenting the environment preserves functionality and reduces access to critical assets.
