Assessment of Barriers (summary)
- Product-first incentives: shipping speed rewarded over security; security seen as blocker.
- Limited security fluency: engineers lack threat-modeling and secure design skills.
- Weak governance: security gates are ad-hoc, no clear RACI or metrics.
- Cultural friction: “move fast” norms, fear of bureaucracy, and low visibility of security ROI.
12‑Month Change‑Management Plan (high level)
Months 0–2: Prepare & align
- Executive sponsor (CPO + CISO) signed charter.
- Baseline: measure mean time to remediate (MTTR), number of security defects in prod, % repos with SCA/DAST.
- Launch communication: “Secure by Design” vision and roadmap.
Months 3–6: Embed practices & incentives
- Rituals: biweekly threat‑modeling workshops per product line; sprint-level security stories.
- Incentives: include security KPIs in OKRs; small bounty/recognition for teams meeting SLAs.
- Training: mandatory role-based training (secure design, threat modeling); certify 2 devs per team as Security Champions.
Months 7–9: Operationalize & govern
- Governance: introduce lightweight guardrails—security definition of done, pull‑request security checks, gated deploys for high‑risk changes.
- Tooling: integrate SAST/SCA/DAST into CI with actionable triage dashboards.
- Metrics: track time-in-pipeline for security fixes, % builds failing security gates, Security Champions coverage.
Months 10–12: Measure, iterate, and scale
- Audit: run purple-team exercises and tabletop incidents.
- Recognition: annual security awards, promotion guidance reflecting security contributions.
- Scale: refine processes, raise certification targets, report measurable reduction in prod incidents and MTTR to execs.
Adoption Indicators (measurable)
- % of projects with completed threat models within design phase (target 90%).
- Reduction in security defects found in production (target -50%).
- MTTR for vulnerabilities (target <7 days for critical).
- Coverage: Security Champion in 100% of teams; training completion 100%.
- CI enforce rate: % of builds blocked by security gates but fixed within sprint.
Why this works
- Aligns incentives to product outcomes, reduces perceived trade-offs.
- Rituals create muscle memory; champions decentralize expertise.
- Governance is lightweight and measurable, minimizing bureaucracy while raising visibility and accountability.
