The advisory's general method: NIAP releases protection profiles requiring CNSA 2.0 support; all new equipment must meet those profile requirements and older equipment must meet them at its next update to remain NIAP compliant; CNSA 2.0 as the preferred configuration begins as soon as validated and tested solutions exist; NIAP profile requirements and NSM-10 technology refresh requirements determine when legacy algorithm support is removed; from then, legacy equipment and software not refreshed regularly needs a waiver and a plan to comply. Where feasible, NSS owners and operators are required to prefer CNSA 2.0 when configuring systems during the transition, and CNSA 2.0 will become mandatory in classes of commercial products within NSS, with other algorithms allowed only in specialised cases.
