CNSA 2.0 guide

CNSA 2.0 planning: inventory, policy, migration evidence, and limits

CNSA 2.0 planning starts with current authoritative guidance and an inventory of affected cryptographic systems. Software can support evidence and workflow, but it cannot decide applicability or certify compliance.

Decision brief

Primary query
CNSA 2.0 compliance
Best for
Teams that need reviewable cryptographic evidence, ownership, and continuous migration control.
Safety boundary
Evidence supports decisions; it is not proof of implementation safety or compliance.

The Commercial National Security Algorithm Suite 2.0 addresses quantum-resistant algorithm selections and transition for National Security Systems. Organizations should consult the current NSA resources, CNSS Policy 15 where applicable, program authorities, and implementation-specific requirements. Marketing summaries and scanner labels are not substitutes for those sources.

A practical operating model maps authoritative requirements into versioned organizational policy, identifies affected systems and products, records evidence and uncertainty, tracks vendor plans, and sequences migration with interoperability testing. Historical evaluations should retain the policy version used so a later guidance update does not rewrite the past.

Capabilities

What the operating model needs to do

01

Authoritative-source register

Track the exact NSA and organizational documents that drive each policy rule.

02

Affected-system inventory

Connect observed algorithms, certificates, protocols, libraries, and products to system ownership.

03

Transition workflow

Assign changes, vendor dependencies, deadlines, test requirements, and approval evidence.

04

Versioned reporting

Show current status and historical decisions without claiming software certification.

Workflow

A repeatable path to evidence

Use explicit scope, accountable decisions, and verification gates. Keep unknowns visible so progress is not manufactured by narrowing the denominator.

  1. 1

    Confirm applicability

    Engage the competent security and acquisition authorities before treating CNSA 2.0 as a control set.

  2. 2

    Translate requirements

    Create reviewable policy rules with citations, dates, scope, and exceptions.

  3. 3

    Inventory and plan

    Discover relevant assets and group migration by shared system, protocol, product, and owner.

  4. 4

    Validate and retain

    Preserve implementation, interoperability, deployment, and approval evidence.

Expected deliverables

Artifacts the next team can inspect

  • Applicability and authority record
  • Versioned policy mapping
  • Affected asset and product inventory
  • Migration and vendor tracker
  • Evidence package with explicit limitations

Buyer checklist

Questions for a proof of value

  1. 01Who determines applicability?
  2. 02Can each policy rule cite the controlling source?
  3. 03Are vendor-controlled products represented?
  4. 04Can historical status be reproduced after guidance changes?
  5. 05Does the platform avoid claiming CNSA certification?

Limits and cautions

What this page does not promise

  • Qubrisk does not certify CNSA 2.0 compliance.
  • NSA guidance and policy documents must be checked for updates.
  • System-specific implementation and validation requirements require competent authority review.
