Remote attestation is a cybersecurity process that enables a device, such as a computer or IoT endpoint, to prove its current software and hardware state to a remote verifier. This is typically achieved using cryptographic techniques and trusted hardware components, like a Trusted Platform Module (TPM). The remote verifier can then determine if the device is running authorized software and has not been tampered with or compromised. Remote attestation is widely used in secure network access, cloud computing, and zero trust architectures to ensure only trustworthy devices can connect to sensitive resources. This process helps prevent attacks by verifying the integrity and authenticity of devices before granting access.
