Certificate Authority Security Council

The Certificate Authority Security Council is an industry consortium founded by major DigiCert, Entrust, GlobalSign, Izenpe, QuoVadis, Symantec (website brand), and Welsh Government-adjacent certificate stakeholders to harmonize practices among public Let's Encrypt rivals, align with Internet Engineering Task Force standards, and engage with regulators such as the European Commission, National Institute of Standards and Technology, and Federal Trade Commission. The council has engaged with standards bodies including the CA/Browser Forum, World Wide Web Consortium, International Organization for Standardization, and worked alongside corporate actors like Microsoft, Google, Mozilla, Apple Inc., and Facebook. It has been cited in debates involving policy makers from the United Kingdom, European Union, and United States about trust frameworks, certificate revocation, and cryptographic transitions with ties to projects like TLS, X.509, OCSP, and Certificate Transparency.

History

The council was formed in the wake of high-profile events such as the DigiNotar compromise, the Symantec certificate scandal, and shifting expectations after revelations tied to Edward Snowden and surveillance disclosures, prompting legacy actors including Verizon, AT&T, Comodo, and GoDaddy affiliates to coordinate. Early statements referenced guidance from the Internet Corporation for Assigned Names and Numbers, the European Telecommunications Standards Institute, and cross-industry dialogues like those at Black Hat, RSA Conference, DEF CON, and OWASP meetings. Milestones include public contributions to the CA/Browser Forum Baseline Requirements, alignment with recommendations from ENISA, and responses to regulatory proposals from the Australian Competition and Consumer Commission and the Canadian Radio-television and Telecommunications Commission.

Membership and Governance

Members historically comprised leading public certificate issuers, corporate security divisions of IBM, Oracle Corporation, Amazon Web Services, and regional authorities such as Japan Network Information Center partners and KISA-connected entities. Governance described in charter documents echoed models used by IEEE, IETF, and ISO working groups, with executive roles often filled by former staff from NortonLifeLock-adjacent teams, legal advisors from firms involved in GDPR litigation, and technical leads who previously contributed to OpenSSL, BoringSSL, and LibreSSL projects. The council maintained advisory interactions with national cyber agencies like the US-CERT, CERT-EU, and the Singapore Cybersecurity Agency.

Purpose and Activities

The council's purpose centered on improving Public Key Infrastructure trust by publishing guidance on certificate lifecycle management, cryptographic algorithm deprecation, and incident response protocols in coordination with projects such as Certificate Transparency, OCSP stapling, and DNSSEC. Activities included white papers, public comment letters to the European Parliament, participation in standards meetings with the W3C, technical workshops with Cloudflare, and collaborative initiatives with academic groups from institutions like MIT, Stanford University, University of Cambridge, and ETH Zurich. The council also issued operational recommendations that influenced product roadmaps at vendors including Cisco Systems, Juniper Networks, F5 Networks, and Akamai Technologies.

Baseline Requirements and Best Practices

The council advocated practices consistent with the CA/Browser Forum Baseline Requirements, encouraging shorter certificate validity, stronger keys following NIST guidance, and robust verification procedures that referenced case law trends from Cour de Justice de l'Union européenne and regulatory guidance from ENISA. Recommendations covered key management, algorithm choices involving RSA, Elliptic Curve Cryptography, and post-quantum proposals discussed in NIST Post-Quantum Cryptography workshops, while promoting deployment patterns used by Google Chrome, Mozilla Firefox, Microsoft Edge, and enterprise platforms like Red Hat and Ubuntu. The group produced checklists used by Certification Practice Statement authors and auditors from firms such as PwC, Deloitte, and KPMG.

Influence on Industry Standards and Policy

Through public statements and liaison roles, the council shaped conversations at the CA/Browser Forum, influenced guidance adopted by IETF working groups on TLS 1.3, and contributed to policymaking dialogues with the European Commission on digital identity frameworks and eIDAS implementation. Its positions were cited in consultations involving National Institute of Standards and Technology publications, drew attention from lawmakers in the United States Congress and the European Parliament Committee on Civil Liberties, Justice and Home Affairs, and informed vendor behavior at platform owners like Apple Inc. and Google LLC. The council engaged with privacy advocates from organizations such as Electronic Frontier Foundation and Center for Democracy & Technology in debates over transparency mechanisms including Certificate Transparency logs and auditability.

Criticism and Controversies

Critics argued that the council represented incumbent certificate issuers such as Symantec, DigiCert, and Entrust and could act to entrench market power against open providers like Let's Encrypt and alternative trust models advocated by groups including EFF and Mozilla Foundation. Controversies included debates over liability limits, perceived regulatory capture cited by commentators from The New York Times, The Guardian, and industry analysts at Gartner and Forrester Research, and scrutiny after high-profile revocations involving Symantec roots and corporate responses covered by outlets such as Wired and MIT Technology Review. Policy critics referenced competition cases in jurisdictions like European Commission Directorate-General for Competition and legislative inquiries by the U.S. Senate Committee on Commerce, Science, and Transportation.
