Challenges in Telecommunication Security Standardization

1. V1.0 ITU-T Workshop on“New challenges for Telecommunication Security Standardization"Geneva, 9(pm)-10 February 2009 Identity Management Anthony M. Rutkowski V-P, Regulatory Affairs and Standards VeriSign, Inc.

2. The challenge of relevance:Why is IdM important? • Identity Management • is the foundation and core for all security • An explosively expanding and vast array of "network nomadic" individuals, providers, and objects • has challenged our ability to effectively manage identities and their “trust anchors”

3. The challenge of a common concept: What is identity? • Identities consist of: • an ensemble of four possible identity “elements” • a binding to an Entity (or Entities) instantiated or asserted at some specific time From the ITU-T Report of the Correspondence Group on the Definition of Identity Complex Version Simple Version

4. The challenge of diversity:Disparate identity communities • Operators and providers • Focussed on revenue opportunities, infrastructure protection, network management forensics, fraud mitigation • Business end-users • Focussed on minimizing costs, employee support, fraud mitigation, inventory and supply chain management • Individual end-users • Focussed on social networking, convenience, identity services (esp. location based services) and portability, controlling unwanted intrusions and mitigating identity theft • Security • Focussed on infrastructure protection, homeland security, NS/EP needs, consumer protection, law enforcement forensics, meeting public policy and legal mandates including personal identity credentials and biometrics • Privacy and anonymity • Spans a broad spectrum from personal identity protection and intrusion minimization to extreme views on complete anonymity, anti-government paranoia and control of all personal identity elements

5. The challenge of focus and vision:What is important? • Discovery of authoritative sources of identities and structured means to query source information • Structured identity ontologies and data models for interoperability • Critical to sharing of identities • Protected identity management “signalling” infrastructure in NGNs • Means to support inter & intra federation identity capabilities • Inter-federation mechanisms are non-existent • Providing for a range of trust relationships (no trust to PKI-based high assurance trust) • Supporting Peer-to-Peer platforms • Implementing trusted Open Identity Architectures as a means of achieving “Identity Network Neutrality” • Achieving effective “trust anchors” • Identity proofing • Identity lifecycle management • Identity status checking on-demand • Identity security • Identity management auditing

6. Capabilities that will make a difference in 2009 The Challenge of Deliverables

7. Provider Identity Trust Anchors • Number one “low-hanging” Identity Management/cybersecurity capability with far reaching positive impact • A universal global means for establishing trust in all organizations that have a network presence • For communications, transactions, software, and secure transport layer • Significant implementation has already occurred • Based on Extended Validation (EV) Digital Certificate standard implementation of ITU-T X.509 platform (also known as EV SSL) • Developed in 2007 by the CA/Browser Forum • Certificates initially issued and browser updates pushed out to most computers in 2008 • Consists of the best combination of identity assurance techniques and platforms • Initial identity proofing based on ETSI standards • Basis for organization trust in Liberty Alliance assurance specifications • Used by the ITU itself! • Upcoming EV enhancements in 2009 • Being extended to all kinds of services and software distribution in 2009, including SIP • Being introduced into ITU-T SG17 through liaison process • Substantial ongoing regional activity to meet localization requirements worldwide • Being considered as an NGN network address enhancement • Cryptography being upgraded to ECC • Embeds many diverse organization identifiers, including ITU-T Object Identifiers (OIDs) that have become Internet global “enterprise ID” of choice • Enhances individual privacy and broadly benefits everybody • May become a global regulatory mandate for cybersecurity

8. Object trust anchors • Real-time Object IDentifier resolution system • Provides a DNS-based means for discovering information about any Object Id • OIDs becoming increasingly important for • Network elements (especially forensic acquisition locations in a network) • Terminal devices, software, RFID tagged objects, sensors, biometric scanners, e-health, power management, and intellectual property • Creation of a new DNS top level domain – OID • Initial implementations occurring in 2009 based on specifications developed in ITU-T and ISO • Real-time token validation protocol systems • Verifying the current status of all object credentials is essential • Allows implementation of “when things go wrong” capabilities • Online Certificate Status Protocol (OCSP) has emerged as means of choice and being mandated by some trust implementations • Similar RSA protocols for token use are being extended

9. Personal identity trust anchors • The world is awash in a sea of countless personal identities • Many personal identities have little or no trust anchors • Diverse expectations exist among people, organizations, and nations concerning the use and availability of identities – many subject to law • Expectations are highly context dependent and often conflicting • Potential “identity network neutrality” challenges abound • Significant contemporary personal identity needs • eHealth • Homeland security • Nomadicity and social networking • Significant technical platforms are emerging • Interoperable and Trust Third Party platforms • OpenID • Personal Identity Portals • National eIDs, especially the EU’s STORK (Secure Identity Across Borders Linked) initiative • One time password tokens • Encrypted biometrics • A major impediment for personal identity trust is lifecycle maintenance • Bears the initial and lifecycle costs, including indemnification • Providing real-time status checking • Accommodating enormously broad assurance spectrum

10. Whose trust anchor:Identity Assurance Interoperability • Many different schema exist to achieve identity assurance • The schema can cover broad ranges from zero trust to very high trust • Expressed as trust levels • Includes diverse context dependencies • How to achieve global identity assurance interoperability among all the existing and potential schema • Possible solution is using ITU-T X.1141 (SAML) to capture and exchange the many different schema via TSB and other bodies

11. Trust Anchors begin at home:Standards and spawned identities • Challenge is to enhance identity management trust anchors by enabling structured discovery and on-demand public access to • Standards • Registrations and assignments specified in standards • Real-time access to standards • Most standards bodies now allow global public access to their specifications • Network IdM/security standards not publicly available have little value • Next step is make them discoverable, versioned, and accessible with a click • Real-time access to registrations and assignments • Standards result in many secretariats and other bodies creating identities • Few provide structured, real-time means for discovery and access • Both ITU TSB and IETF IANA are building capabilities • Can serve as models for other bodies and administrators worldwide
