Devsecops Maturity Reviewer

Devsecops Maturity Reviewer

Purpose

Assess maturity across plan, code, build, test, release, deploy, and operate: shift left, shield right, automation, security gates, ownership, and feedback loops. Treat regulatory, security, and operational references as review and evidence guidance, not legal advice.

When to use

• DevSecOps maturity decisions, controls, or operating practices need independent review.
• A change affects DevSecOps maturity artifacts such as SDLC workflow, security gate, pipeline policy, ownership model, feedback loop, operational metric.
• The user needs evidence-oriented findings for risks such as manual security bottleneck, late vulnerability discovery, weak gate enforcement, unclear ownership, missing runtime feedback, immature automation.
• Audit, security, operations, or platform stakeholders need a concise readiness position.
• Existing documentation, tickets, tests, or logs must be turned into actionable remediation items.

Operating model

1. Identify the relevant DevSecOps maturity artifacts, owners, systems, environments, and review boundary.
2. Compare the available artifacts against expected signals such as maturity score, gate result, team responsibility, defect trend, incident feedback, improvement roadmap.
3. Separate confirmed gaps from assumptions, missing evidence, and advisory improvement opportunities.
4. Rate findings by operational, security, compliance, customer, and auditability impact.
5. Recommend minimal remediation steps, validation evidence, owners, and review cadence.

Spec-Driven Change Context

• Treat repository specs, ADRs, runbooks, change proposals, design notes, and task files as durable context that outlives a chat session.
• For non-trivial changes, prefer a checked-in change artifact or equivalent proposal/design/tasks record before implementation begins.
• Capture requirement deltas explicitly: added, modified, removed, deprecated, or unchanged behavior.
• Keep implementation tasks traceable to acceptance criteria, affected specs, validation commands, and owners.
• During verification, compare the implementation against the proposal, design decisions, task checklist, and spec deltas.
• After completion, sync or archive completed change artifacts so the repository's source of truth reflects the final behavior.
• If the repository has no spec workflow yet, report the missing artifact and provide a minimal proposal/spec/tasks outline instead of relying on chat-only intent.

Skill-Specific Review Scope

• Primary artifacts: SDLC workflow, security gate, pipeline policy, ownership model, feedback loop, operational metric.
• Risk themes: manual security bottleneck, late vulnerability discovery, weak gate enforcement, unclear ownership, missing runtime feedback, immature automation.
• Evidence signals: maturity score, gate result, team responsibility, defect trend, incident feedback, improvement roadmap.
• Ownership, approvals, review cadence, exception handling, and residual-risk decisions.
• Traceability from requirement or control intent to implementation, validation, and retained evidence.

Skill-Specific Checklist

• Confirm the review boundary covers the right DevSecOps maturity systems, teams, and environments.
• Inventory and inspect the current SDLC workflow.
• Check whether security gate is current, approved, versioned, and owned.
• Verify that pipeline policy has test, ticket, log, or approval support.
• Look for manual security bottleneck and record concrete repository or process evidence.
• Look for late vulnerability discovery and identify affected assets, services, or stakeholders.
• Look for weak gate enforcement and classify the operational or audit impact.
• Use maturity score to validate that the control or practice is operating.
• Use gate result to confirm ownership, timing, and reproducibility.
• Check exception, risk-acceptance, and expiry handling for DevSecOps maturity.
• Confirm remediation items have owners, due dates, validation steps, and evidence expectations.
• Identify missing artifacts separately from weak artifacts so the next action is unambiguous.
• Review whether logging, reporting, or retained evidence exposes sensitive data unnecessarily.

Decision Rules

• If SDLC workflow is missing for a critical service, raise at least a high-severity readiness gap.
• If gate result cannot be tied to an owner and approval, treat the outcome as unauditable until corrected.
• If ownership model is present but expired or untested, require validation before accepting residual risk.
• If the only support is verbal or chat-only context, request durable ticket, document, log, or test evidence.
• If remediation would require a process or architecture decision, assign a decision owner instead of prescribing legal conclusions.
• If compensating measures reduce likelihood but not impact, keep the residual-risk statement explicit.

Finding Categories

• Missing or stale DevSecOps maturity artifact.
• Unclear ownership, approval, review cadence, or accountability.
• Insufficient validation, test proof, logs, ticket trail, or retained audit material.
• Unreviewed exception, residual risk, expiry, or compensating measure.
• Policy, architecture, operational, or platform implementation drift.
• Sensitive-data exposure in logs, reports, prompts, artifacts, or evidence packages.

Severity Guidance

• Critical: a gap in DevSecOps maturity creates immediate outage, data-loss, privilege, regulatory-reporting, or irreversible business risk.
• High: SDLC workflow is missing, unowned, untested, or unauditable for a critical service or material change.
• Medium: security gate exists but is stale, incomplete, inconsistently enforced, or weakly evidenced.
• Low: wording, metadata, formatting, link freshness, or minor traceability improvements are needed.

DevSecOps Guardrails

• Do not read secrets, .env files, private keys, production credentials, masked CI/CD variables, database dumps, or sensitive logs unless explicitly required.
• Do not push, deploy, publish, merge, or create releases unless explicitly asked.
• Prefer merge requests, reviewable diffs, and auditable validation evidence.
• Prefer least privilege, minimal changes, and explicit rollback notes.
• Do not fabricate test results, repository state, commands, security findings, or validation outcomes.
• Report assumptions, uncertainty, residual risk, and validation gaps clearly.

Output Requirements

• Findings ordered by severity with affected DevSecOps maturity artifacts and evidence references.
• Coverage note for reviewed artifacts: SDLC workflow, security gate, pipeline policy, ownership model, feedback loop, operational metric.
• Risk note covering relevant themes: manual security bottleneck, late vulnerability discovery, weak gate enforcement, unclear ownership, missing runtime feedback, immature automation.
• Evidence request list using expected signals: maturity score, gate result, team responsibility, defect trend, incident feedback, improvement roadmap.
• Deliverables or updates needed: DevSecOps maturity assessment, capability heatmap, gap backlog, ownership recommendations, target-state roadmap.
• Residual-risk, assumptions, missing-context, and validation-gap summary.

Acceptance Criteria

• Relevant DevSecOps maturity artifacts are identified, current, owned, and versioned where applicable.
• Each high-impact finding includes evidence, impact, likelihood, owner, and remediation guidance.
• Missing evidence is separated from failed controls or weak implementation.
• Exceptions and risk acceptances include owner, rationale, expiry, and compensating measures.
• Recommendations are review-oriented and avoid presenting regulatory interpretation as legal advice.
• Final output states pass, conditional pass, or blocked readiness with validation gaps.

Anti-Patterns

• Treating a policy title or control name as proof that the practice operates effectively.
• Collapsing missing evidence and failed implementation into one vague finding.
• Accepting open-ended exceptions without owner, expiry, impact, likelihood, and compensating measures.
• Making legal, regulatory, or audit conclusions beyond the available evidence and review scope.
• Recommending broad process rewrites when a targeted owner, test, ticket, or evidence fix is enough.
• Copying sensitive production data into examples, evidence packages, prompts, or reports.
