System health check for network equipment and IoT devices
Today, network equipment and IoT devices face a constant barrage of attacks aimed at exposing vulnerabilities in software and firmware. Worst still, cyber threats have become so sophisticated that conventional defense-in-depth cybersecurity measures may even fail to detect them. Once malware is on a device, it may remain there undetected for long periods as it often works undetected in the background. By the time most users realize they have suffered a data breach, they have actually been under attack for weeks, months, or even years.
A system health check supported by Infineon’s OPTIGATM TPM lets users check that their devices have not been manipulated. The TPM provides a secured identity and storage space for system control mechanisms that may check whether hardware and software are still running as intended. The system notifies the user if it does detect changes, e.g. caused by malware.
When devices start up, the software and firmware are measured by the Linux Integrity Measurement Architecture (IMA) and the results are stored in the OPTIGATM TPM Platform Configuration Registers (PCRs). The measurements can then be retrieved by a remote attestation server to determine the configuration of the device at the time it was booted as well as during runtime. The PCR is protected against being rolled back to a previous value. The attestation server polls a platform at set intervals, verifying either that the PCRs in the OPTIGATM TPM have not changed or that the new PCR values are trustworthy. The PCR values are signed with a private Attestation Identity Key (AIK) to reduce the risk of forgery.
For service providers, this means that their services are stable and reliable, and that devices in their network have been checked for manipulation. OPTIGATM TPM also gives device and system manufacturers an opportunity to access new markets requiring new – and differentiating – levels of security. End users benefit from increased security for their sensitive data while still enjoying the same or an even better user experience.
To facilitate use and integration for device and system manufacturers, Infineon has created a Github repository with documents as well as demonstrator source code.
