Seamlessly-applied Device Security
and Unsupervised Machine Learning
Seamless Embedded Security
Karamba Security’s XGuard is an integrated solution of embedded software agents and a cloud-based backend. XGuard agents deterministically prevent malware and fileless attacks. The backend engine detects anomalous behavior and provides proactive alerts about suspicious devices.
XGuard agents are integrated as part of the firmware build toolchain. No source code is required, development processes are untapped, and the agent is seamlessly integrated with the product binaries.
Verification & validation are likewise unchanged. The product software image is tested with XGuard embedded into it, without requiring changes to test plans, as XGuard’s addition doesn’t change product functionality.
XGuard Agent: Negligible Performance Overhead
The XGuard embedded agent is designed for embedded systems, with low CPU and memory consumption. The agent takes up to 5% CPU overhead, 5% memory size, and about 10% of the flash size.
The agent local analysis and payload optimization reduce device traffic to the backend by 90%.
XGuard Backend: Unsupervised Machine Learning
XGuard’s backend has a set of predefined monitored behaviors but it also observes a huge number of events across the entire fleet and uses adaptive unsupervised machine learning to find anomalies that indicate threats. This allows Security Operations Center (SOC) teams to investigate highlighted anomalies and determine incidents and root cause.
XGuard automatically adjusts to a wide variety of device and fleet behaviors without requiring any user intervention.
Broad Threat Coverage
XGuard software enables OEMs and device manufacturers to assure their customers a high level of protection against cyberattacks.
- Malware is deterministically detected as foreign code, which wasn’t part of the original build, and is prevented from executing.
- Fileless attacks, which exploit in-memory vulnerabilities such as buffer overflow, are deterministically detected and prevented automatically by utilizing Karamba’s patented Control Flow Integrity (CFI).
- The backend analytics engine points at a significant number of hacking attempts such as password guessing, privacy violations, and rogue devices.
ISO21434 and UNECE R155 Compliance
Software Integrity, security event logging and an update mechanism form the cornerstone of many cyber-related regulations in various industries.
Automotive OEMs and suppliers, who must meet the ISO21434 and UNECE R155 cybersecurity standards, use XGuard as for achieving compliance. The software, which is seamlessly integrated, and auto-adapts to fleet behavior, addresses the UNECE R155 requirements for software integrity, OTA updates, authentication, and logging, without taking an extra toll on R&D, or requiring changes to the ECU architecture.
