Our Comprehensive Security Audit Process

Ledger has established a rigorous security audit specification to validate application conformance to their stringent security standards. Kudelski IoT tests against that specification by putting applications through a thorough 6-stage audit process:


Application Privileges

We verify the application flags (privileges) and allowed derivation paths to ensure proper access control.


Our audit identifies any compilation warnings and ensures they have not been silenced.


We run a series of unit tests and end-to-end tests to confirm successful execution. Additionally, we assess the tests' soundness and coverage of the application's features.

Static Analysis

We utilize scan-build and Ledger's scan options to detect potential defects.


We compile the code with a code fuzzer and run a fuzzing campaign to identify any vulnerabilities.

Manual Code Review

Our experts thoroughly analyze all transaction fields, displayed transactions, transaction parsers, and field formatters. We ensure that sensitive data is properly erased and confirm that blind signing is not permitted.
