Remote Attestation: Proving Your Hosts Are Truly Trusted Before They Run

Remote Attestation

I explore how Remote Attestation uses TPMs to cryptographically verify a host's hardware, firmware, and kernel state before it joins your network. This approach ensures that even if an attacker compromises a machine, they cannot persist through a reboot or serve traffic without detection. By enforcing strict boot measurements, we can encrypt data, issue certificates, and schedule workloads only on verified, trusted hosts, creating a solid foundation for runtime security.

"Without it you can't trust your hosts themselves and can't make further security guarantees. Houses built on sand and all that."
