Why this module. Engineering teams measure DORA. Security teams measure CVE backlog. DevSecOps requires a unified metric set — measuring how secure software is delivered, not just secure or how fast. This module is the metrics blueprint.

Why this module. Engineering teams measure DORA. Security teams measure CVE backlog. DevSecOps requires a unified metric set — measuring how secure software is delivered, not just secure or how fast. This module is the metrics blueprint.

DORA — the engineering baseline

  • Deployment Frequency — how often code reaches production
  • Lead Time for Changes — commit to production time
  • Change Failure Rate — % of deployments causing incidents
  • Mean Time to Recover — how fast from incident to recovered

“Elite” teams: deploy multiple times daily, lead time < 1 hour, CFR < 15%, MTTR < 1 hour.

DORA + security overlay

Add security to each:

  • Deployment Frequency (Security) — % of deploys that include security improvements
  • Lead Time (Security) — time from CVE published to patched in production
  • Change Failure Rate (Security) — % of deploys that introduce a security regression
  • MTTR (Security) — time from breach detection to containment

Vulnerability metrics

  • Mean Time to Detect (MTTD)
  • Mean Time to Remediate (MTTR-vuln)
  • SLA Compliance — % of vulns resolved within priority SLA
  • Backlog Aging — distribution of vuln age
  • New vs Resolved — net flow per week

The BSIMM maturity model

BSIMM (Building Security In Maturity Model) — observed practices across hundreds of companies. 121 activities across 12 practices. You score yourself; benchmark against industry.

BSIMM observations: most enterprises sit at 30-60% activity coverage. Top quartile cover 70-85%.

OWASP SAMM

Lighter alternative. 5 business functions × 3 practices each × 3 levels of maturity.

Practical for SMBs; full-form takes 1-2 days to assess vs BSIMM’s weeks.

The metrics dashboard hierarchy

  • Operational (daily) — failed builds, vuln backlog, SLA breaches, incidents
  • Tactical (weekly) — DORA + security trends, top 10 vulns
  • Strategic (monthly) — maturity progress, headcount-adjusted productivity, customer-impacting incidents
  • Executive (quarterly) — risk trend, regulatory readiness, peer benchmark

The metric that backfires

“Number of vulns found” — celebrates noise. The team that finds 1000 vulns isn’t better than the team that finds 100; might be using a worse scanner with more false positives.

Better: “Number of vulns prevented per release” — incentivises pre-commit and SAST quality. Or: “Time from CVE publication to patched in production” — incentivises automation.

Defender’s checklist

  • DORA metrics measured + security overlay added.
  • Vuln SLA defined; compliance tracked.
  • BSIMM or SAMM self-assessment annually.
  • Dashboard hierarchy from operational to executive.
  • Quarterly review with engineering leadership.
  • Beware vanity metrics; reward outcomes not activity.
