CAQH CORE 270: Connectivity Rule Authentication Standards
CAQH CORE 270: Connectivity Rule (Connectivity & Security Subgroup) evaluated the connectivity implementations used by its members, including what types of submitter authentication methods were being used. The results showed widespread use of both username/password and X.509 client certificate authentication. Though username/password is the base requirement with Phase I and is widely implemented across the industry, X.509 Certificates was agreed to be an important step toward ensuring data security over the public Internet and a direction in which the industry is heading. Similar to the decision on envelope standards, a decision was made to allow both authentication standards with the necessary conformance guidance for all stakeholders.
CAQH CORE expects that in future phases CAQH CORE requirements will include single, specific standards in both of these areas. The Phase II inclusion of two envelope and authentication standards and appropriate conformance requirements greatly improves the situation in the marketplace by reducing variation in options currently available and in use. This phased step will provide the basis for a more informed decision when considering single standard recommendations moving forward.
