XGuard Suite is an embedded security solution for connected devices such as automotive ECUs and IoT systems. It provides runtime self-protection capabilities that are integrated into the device's software development lifecycle without requiring changes to development processes or architectures. The suite consists of four main components: - **Runtime Integrity Platform:** Automatically scans device binaries and establishes a factory-settings baseline of legitimate binaries, messages, and function calls. Deviations from this baseline are flagged as exploit attempts. - **Control Flow Integrity (CFI):** Detects illegitimate in-memory operations associated with fileless attacks, memory corruption exploits, and remote code execution attempts. The patented CFI implementation imposes less than 5% CPU and memory overhead. - **Executables Whitelisting:** Automatically generates binary whitelists during the image build process to block dropper attacks, file traversal exploits, and unauthorized executable execution — without developer intervention. - **Authentication Encryption (SafeCAN):** Provides authentication and encryption for critical network commands over CAN bus networks with negligible performance impact on the ECUs involved and zero additional network overhead. The suite is designed for resource-constrained embedded environments, with a reported footprint of approximately 5% CPU overhead, 10% image size increase, and no network overhead impact. It defends against malware, ransomware, advanced persistent threats, and fileless attacks.
