Where 15,408 fits
Why 15,408 is special
Its Evaluation Assurance Levels are frequently quoted as though a higher number means a more secure product, when they measure how thoroughly a claim was checked, not how strong the claim was.

1 × 10,000 + 5 × 1,000 + 4 × 100 + 8 × 1 = 15,408. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Common Criteria assurance levels measure how thoroughly a claim was checked, not how strong the claim was.
Common Criteria evaluates a product and ISO 27001 an organisation's management of security; a certified product does not certify its operator.

Technology & computing
ISO/IEC 15408 defines security functional and assurance requirements and the EAL scale. An EAL states the rigour of evaluation against a stated security target; a product evaluated at a high level against a narrow target is not thereby broadly secure.
