Information About Boot Integrity Visibility
Boot Iintegrity Visibility allows Cisco's platform identity and software integrity information to be visible and actionable. Platform identity provides the platform’s manufacturing installed identity. Software integrity exposes boot integrity measurements that can be used to assess whether the platform has booted trusted code.
During the boot process, the software creates a checksum record of each stage of the bootloader activities.
You can retrieve this record and compare it with a Cisco-certified record to verify if your software image is genuine. If the checksum values do not match, you may be running a software image that is either not certified by Cisco or has been altered by an unauthorized party.
Boot Integrity Visibility is supported only on the active supervisor. It does not support high availability scenarios.
