During December 2024, Trung contributed to the microsoft/lisa repository by developing Azure Linux attestation testing using the SnpGuest tool. Trung implemented attestation report testing for Azure Linux, updated the Cargo build process to explicitly pass build options, and expanded the CVM attestation test suite to support both Ubuntu and CBLMariner distributions. This work leveraged skills in cloud computing, DevOps, and security testing, with Python as the primary language. By integrating SnpGuest to manage the attestation workflow, Trung improved security validation coverage and cross-distro compatibility, resulting in more robust attestation validation and supporting faster, more reliable release cycles for cloud environments.
