Firmware Validation

AltaNivel 1Revisión manualaruba-cx

Descripción

All AOS-CX switch firmware is signed by HPE at the time the firmware is created. The firmware signature is verified at the time of download and verified at every boot. The public keys used to verify the firmware is stored within the bootloader and firmware. The firmware is digitally signed with RSA-3072 and SHA-256. If the switch firmware validation fails at boot, the switch will fail to boot with one of the following error messages and drop the user into the ServiceOS login screen: Error: Signature verification failed Error: Signature not found Error: Invalid signature

Cómo se verifica

Método de auditoría: Revisión manual

Esta recomendación no se puede verificar automáticamente. Un escaneo la lista con estas instrucciones cuando se pasa --include-manual.

Run 'show images verify primary' and 'show images verify secondary'. Both must report that the image is valid (signed and compatible) before the switch is booted from it.

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Firmware without a valid signature will not boot. A new firmware image with a valid signature should be copied onto the device.
