Executive Summary
This white paper translates SCRM into a buildable checklist for micro-ISVs supporting VA efforts such as PathFinder. It focuses on what reviewers and vendor risk teams typically look for:
SBOM (what's in your software) and how you generate it
Dependency pinning and update discipline
Vulnerability response SLAs
Supplier attestations
CI/CD hardening
Evidence packages you can hand to procurement/security without scrambling
The goal is simple: make your software supply chain auditable, resilient, and defensible—without creating a bureaucracy you can't sustain.
What "SCRM" Means in Plain English
SCRM is how you answer three questions:
What are we running? (components, versions, build inputs)
What could go wrong? (vulnerabilities, malicious packages, compromised suppliers)
How do we respond? (detection, patching, communication, proof)
For micro-ISVs, SCRM is less about writing a 60-page policy and more about proving you can identify what's in your product, control changes to it, react fast when risk changes, and prevent your pipeline from becoming an attacker's entry point.
The VA Lens: What Reviewers Typically Care About
In VA procurement and security review contexts, the practical concerns often look like this:
Can you produce an SBOM and keep it current?
Do you know your critical dependencies (and who maintains them)?
How quickly can you patch a high-severity vulnerability?
Can you prove your builds are trustworthy and repeatable?
Do you prevent secrets leakage and unauthorized releases?
Do you have a credible disclosure and incident communication process?
If you can answer those with evidence, you're ahead of most small vendors.
The Micro-ISV SCRM Control Set
1) SBOM: Your "Ingredients Label"
What VA wants: a clear inventory of third-party components and versions.
What to implement (minimum viable):
Generate an SBOM automatically during CI builds
Store SBOMs per release (not just "latest")
Use a standard format (e.g., SPDX or CycloneDX)
Tie SBOM to a specific build artifact/version
Evidence you should be able to provide:
Example SBOM for the current production release
CI job output showing SBOM generation
A simple mapping: release version → SBOM file
Common gap: SBOM exists once, manually, and isn't tied to releases—so it can't be trusted as current.
2) Dependency Pinning: Prevent Surprise Drift
What VA wants: confidence you aren't accidentally pulling new code into production.
What to implement:
Pin direct dependencies to known-good versions
Use lockfiles consistently (and treat them as first-class artifacts)
Restrict auto-updates to controlled workflows (PR + review)
Maintain a cadence for dependency updates (weekly/biweekly)
Evidence:
Repo shows lockfiles and pinned versions
A documented "dependency update process" (even 1 page)
PR history demonstrating controlled updates
Common gap: floating versions ("latest") and ad-hoc updates that introduce unreviewed risk.
3) Vulnerability Management + Response SLAs
What VA wants: not "we care about security," but "we can respond fast."
Minimum viable program:
Automated dependency scanning (SCA) in CI
A triage workflow (who reviews, how often)
A severity-based remediation SLA
A documented exception process (risk acceptance with compensating controls)
Example SLA framework:
Critical (known exploited / high impact): mitigation or patch in 24–72 hours
High: patch in 7–14 days
Medium: patch in 30–60 days
Low: patch in normal maintenance cycle
Evidence:
A vulnerability policy page with SLAs
Screenshots/exports from your scanner showing findings and resolution timestamps
Release notes or changelog entries referencing security fixes
Common gap: scanning exists but nobody owns remediation, so findings accumulate.
4) Supplier Attestations: Only Claim What You Can Prove
What VA wants: credible statements about your practices and your upstream suppliers.
As a micro-ISV, you can't audit every upstream maintainer—but you can do due diligence.
What to implement:
Maintain a "critical supplier list" (top dependencies and service providers)
Document selection criteria (maintenance activity, reputation, security posture)
Track where your code runs (cloud provider, CI provider, artifact registry)
Require MFA and least privilege on supplier accounts you control
Evidence:
Supplier inventory (critical dependencies + vendors)
Account security settings (MFA enforced, access reviews)
A simple annual/quarterly supplier review note
Common gap: broad, vague attestations that collapse under basic questioning.
5) CI/CD Hardening: Protect the Build Pipeline
This is where modern supply chain attacks land: compromised CI, stolen tokens, tampered artifacts.
Minimum viable CI/CD hardening:
MFA enforced on source control and CI accounts
Protected branches + required reviews for main
Signed commits or verified commit policies (where feasible)
Secrets stored in a vault/CI secrets manager (never in code)
Short-lived credentials for CI jobs when possible
Artifact integrity: store build outputs in a controlled registry
Release approvals for production deploys (even if you're solo)
Evidence:
Screenshots/config exports of branch protection rules
CI configuration showing secrets handling
Release workflow showing approvals and traceability
Artifact registry logs (who published what, when)
Common gap: CI has admin tokens with broad scope and uncontrolled access to main.
6) Environment and Configuration Control
Supply chain risk isn't only libraries—misconfigurations create exposure.
What to implement:
Infrastructure-as-code where possible
Versioned configuration changes (PR-reviewed)
Separate dev/stage/prod with least privilege
Logging for admin changes and deployment events
Evidence:
IaC repo or config change history
Access control model for environments
Deployment logs tied to releases
The "What VA Actually Wants" Evidence Package
If you're supporting VA PathFinder S-6870, build a small, repeatable evidence bundle you can refresh each release or each month:
☐ Current SBOM (per release)
☐ Dependency update policy (1–2 pages)
☐ Vulnerability response policy with SLAs
☐ Recent vulnerability remediation examples (before/after)
☐ CI/CD security controls summary (branch protection, MFA, secrets handling)
☐ Supplier inventory (critical dependencies + service providers)
☐ Release traceability (version → commit → build → artifact)
☐ Incident disclosure contact + process (who to notify, how fast)
This is the difference between "we're secure" and "we can prove it."
Common Micro-ISV Gaps (and How to Address Them)
Gap | Fix |
SBOM as a one-time artifact | Generate automatically per release |
No lockfiles / floating dependencies | Pin and review updates |
No SLA ownership | Assign a human owner, even if it's you |
Secrets in code or long-lived tokens | Move to managed secrets + rotate |
Unprotected main branch | Require PR reviews and checks |
No release traceability | Tie every deploy to a version and commit |
A 30-Day Implementation Plan (Realistic for Small Teams)
Week 1:
Enforce MFA everywhere (source control, CI, cloud)
Turn on branch protection + required reviews
Establish lockfiles and pin dependencies
Week 2:
Add SBOM generation in CI and store per release
Add SCA scanning in CI with alerting
Week 3:
Publish vulnerability response SLAs + exception process
Create supplier inventory (critical dependencies + vendors)
Week 4:
Harden release workflow (approvals, artifact registry discipline)
Build the evidence package folder and keep it current
Conclusion
VA doesn't need micro-ISVs to run enterprise bureaucracy. VA needs micro-ISVs to be predictable, auditable, and responsive when the supply chain shifts. If you can produce an SBOM per release, control dependency changes, meet vulnerability response SLAs, harden CI/CD, and provide a clean evidence package, you'll meet the intent of SCRM expectations in a way that's credible for PathFinder.
