Postal Service Management of End-of-Life Devices

The Postal Service’s IT infrastructure includes thousands of routers, switches, virtual private network gateways, firewalls, voice over internet protocol equipment, and other devices that support the delivery of business systems and IT-enabled processes. These network devices must be monitored, maintained, and replaced appropriately to provide a high-level of network performance and prevent unwanted outages. Our objective was to determine whether the Postal Service is effectively managing End-of-Life (EOL) network devices. The scope of our review was information technology (IT) network devices [redacted] that are connected to the Postal Service’s IT network and identified as EOL.
