We created a CodeQL query that reduced 2,500+ compiler warnings about implicit conversions in OpenVPN2 to just 20 high-priority cases, demonstrating how to effectively identify potentially dangerous type conversions in C code.
You and your team should incrementally update your threat model as your system changes, integrating threat modeling into each phase of your SDLC to create a Threat and Risk Analysis Informed Lifecycle (TRAIL). Here, we cover how to do that: how to further tailor the threat model we built, how to maintain it, when to update it as development continues, and how to make use of it.
In the race to secure cloud applications, AWS Nitro Enclaves have emerged as a powerful tool for isolating sensitive workloads.
But with great power comes great responsibility-and potential security pitfalls. As pioneers in confidential computing security, we at
Trail of Bits have scrutinized the attack surface of AWS Nitro Enclaves, uncovering potential bugs that could compromise even these
hardened environments.
AWS Nitro Enclaves are locked-down virtual machines with support for attestation. They are Trusted Execution Environments (TEEs), similar to Intel SGX, making them useful for running highly security-critical code. However, the AWS Nitro Enclaves platform lacks thorough documentation and mature tooling. So we decided to do some deep research into it […]
We are publishing a set of custom CodeQL queries for Go and C. We have used them to find critical issues that the standard CodeQL queries would have missed. This new release of a continuously updated repository of CodeQL queries joins our public Semgrep rules and Automated Testing Handbook in an effort […]
