Tag :: Secure Boot

Secure boot is a security feature available in Aboot (Arista bootloader) that verifies the cryptographic signature of the EOS SWI (software image) before it is booted. Aboot embeds certificates that allow it to recognize and validate official EOS releases from Arista. If the signature verification is successful, the secure boot check passes and Aboot proceeds to boot the SWI. If the signature verification fails, the boot is aborted.

enrollz/attestz defines a set of gRPC-based services for TPM enrollment and attestation of network devices. Enrollz: provides the capability to verify the switch’s TPM-rooted identities and rotate switch owner certificates on the device. Attestz: provides the capability to attest the device by inspecting the contents of the different PCR ensuring no malicious tampering.
