Integrate and operate hardware-backed key storage (e.g., TPM/secure elements) and sealed secrets for on-vessel services

Harden network paths over constrained links: TLS/mTLS, VPN overlay policies, and least-privilege service access

Reduce attack surface in embedded services (capabilities, seccomp/AppArmor where appropriate, safe process execution, input validation)

Build tamper-evident, structured logging and diagnostics suitable for ship→shore analysis and incident response

Perform threat modeling, code reviews, and security testing (static/dynamic analysis, fuzzing, negative testing)

Troubleshoot and debug complex security issues in fielded systems; author runbooks and safe-rollback procedures

Document designs, processes, and verification results for compliance and knowledge sharing; contribute to secure coding guidelines

Stay current on emerging security technologies and best practices relevant to embedded Linux and autonomous systems
