Karamba XGuard Whitelisting is an embedded application whitelisting solution designed to prevent the loading of unauthorized executables on embedded systems such as ECUs and IoT devices. The product automatically maps and builds a whitelist of authorized executables during the development phase. At runtime, any attempt to load scripts, binaries, or libraries not present on the whitelist is blocked before execution. This deterministic approach eliminates the need for heuristic or behavioral analysis, resulting in no false positives by design. Key operational characteristics: - Whitelisting is immutable and always active once deployed - No cloud connectivity is required for enforcement - Supports large applications with thousands of executables through an automated, granular whitelist-building process - Allows signed binaries from third-party suppliers and update diffs from an image authority, accommodating supply chain dynamics - Configurable to prevent unauthorized file load attempts immediately upon detection The product is part of the broader XGuard Suite and is marketed for use in automotive (ECU protection) and IoT device security contexts. It is positioned as a bolt-on capability that can be added after the build process.
