Tamper Detection
Tamper detection is a security feature implemented in Cisco 8300 Series Secure Routers to identify potential tampering events. Each router is shipped from the manufacturer with its chassis cover securely fastened. If the chassis cover is opened after shipment, the hardware records all chassis cover open and close events in tamper-proof memory, regardless of whether the device is powered on or off.
On boot up, the software reads the latest event index and compares it with previously known indices. When there is a discrepancy, the software generates a SYSlog message during startup to report the tamper event. When the device is in fully powered up state, software will generate syslog message and SNMP trap immediately.
Benefits
Tamper Detection notification detects unauthorized physical access or attempts to compromise the device, helping protect sensitive data and network integrity.
Limitations
Tamper Detection feature is currently not supported on SDWAN/SD-Routing mode.
