What stack and design did you use for the AI remediation tool, and what would you improve in v2?
Resume & Behavioral · Basic level
Answer
I would frame the AI-assisted remediation work as reducing repetitive security toil while keeping human control over risky changes. The tool ingests findings, normalizes them, maps them to service owners, enriches them with dependency and version context, and drafts clear remediation guidance or PR/ticket content. The AI part helps summarize and recommend, but deterministic logic should handle facts like package versions, ownership, severity, and policy. The business value is faster, more consistent remediation and less manual triage effort for engineers.
Technical explanation
The workflow is: ingest finding -> normalize -> enrich -> prioritize -> recommend -> create ticket/PR -> track closure.
Do not present AI as blindly auto-fixing production. Senior DevSecOps judgment means guardrails, human approval, CI validation, and feedback loops.
The 90% triage claim should be defended with baseline minutes per finding or batch, after-automation review time, sample size, and rework/quality metrics.
Hands-on example
1. Input scanner data: CVE, package, version, repo, severity, fix version, and service metadata.
2. Enrich with CODEOWNERS, SBOM/dependency tree, package registry, internal playbooks, exploitability context, and previous remediation patterns.
3. Generate recommendation: fixed version, dependency path, test command, PR description, risk note, and owner.
4. Guardrails: no auto-merge, require CI pass, owner approval, security validation, and feedback capture for accepted/rejected suggestions.
