2 Lawful Interception (LI) & Data Retention (DR) Delivery of intercepted data in transit (LI) and location (DR) To support criminal investigation, counter terrorism Define Handover Interface from Operator to Authorised Organisation (typically a LEA) Maintenance of suites for LI and DR, new work and any technical details added asneeded 2

3 LI in ETSI SA3-LI ATTM Handover Interfaces for transport of Lawful Interception and Retained Data TISPAN TETRA European Telecommunications Standards Institute are standardized by Technical Committee Lawful Interception Lawful Interception Retained Data 3 Security LI & RD environment

5 Why LI implementation in the EU 17th January 1995: EU Council of Ministers adopted resolution COM 96/C329/01 on Lawful Interception The providers of public telecommunications networks and services are legally required to make available to the authorities the information necessary to enable them to investigate telecommunications 5

6 Types of LI data Intercept Related Information (IRI) collection of information or data associated with telecommunication services involving the target identity: communication associated information or data (including unsuccessful communication attempts) service associated information or data (e.g. service profile management by subscriber) location information Content of Communication (CC) information exchanged between two or more users of a telecommunications service 6

7 General Network Arrangement communication associated information network Content of Communication service associated information location information interception interface (internal) Handover Interface result of interception (IRI + CC) Law Enforcement Monitoring Facility 7

8 LI Handover Interface specification ETSI TS (= old ETSI ES ) Handover Interface for the Lawful Interception of Telecommunications Traffic generic flow of information and procedures and information elements, applicable to any future telecommunication network or service circuit switched and packet data covered technologies PSTN, ISDN, GSM, UMTS (CS), GPRS, TETRA wire line NGN (including PSTN/ISDN emulation) wire line IMS PSTN simulation 8

9 Handover of LI over IP services TS family y( (7 parts) Application SSD for Messaging Services part 02 SSD for Internet Access Services part 03 SSD for Layer 2 Services part 04 SSD for IP Multimedia Services part 05 SSD for PSTN/ ISDN Services part 06 SSD for Mobile Services part 07 SSD -> Service-Specific Details on top Generic Headers Session Transport Network and below Handover manager Delivery session Transport layer Network layer Delivery network TS part 01 9

10 LI specifications in 3GPP ETSI TS (3GPP TS ) Lawful interception requirements provides basic interception requirements partly based on ETSI TS ETSI TS (3GPP TS ) Lawful interception architecture and functions ETSI TS (3GPP TS ) Handover interface for Lawful Interception 10

11 TC LI relationships with other bodies 3GPP/SA3 LI (LI for UMTS & GSM) ETSI/EP TETRA (LI for Tetra system) ETSI/TC NTECH (within EP E2NA) ETSI/TC CABLE ETSI/TC SES ETSI/TC PLT (LI for fixed NGN & fixed IMS) (LI for IPCableCom) (LIfor satellitesystems) systems) (LI for Powerline Communications) National and Regional Law Enforcement Agencies and STC/ILETS ATIS/PTCS LAES SC (T1.678 v1 / J STD 025 B) ITU T SG17 (Security Group) ISO/IEC JTC1/SC27 (Security Group) 11

12 Why DR implementation in the EU 15th of March 2006: the European Parliament and the Council of the European Union adopted Directive 2006/24/EC on Data Retention Data generated or processed in connection with the provision of publiclyavailable electronic communications services or of public communications networks need to be retained 12

13 DR specifications in TC LI ETSI TS Requirements of LEAs for handling Retained Data guidance and requirements for the delivery and associated issues of retained data of telecommunications and subscribers set of requirements relating to handover interfaces for retained traffic and subscriber data requirements to support the implementation of Directive 2006/24/EC freedom for national regulations,,procedures and processes ETSI TS Handover interface for the request and delivery of Retained Data handover requirements and handover specification for the data that is identified d in EU Directive 2006/24/EC / on Retained Data and in national legislations as defined in TS considers both the requesting of retained data and the delivery of the results defines an electronic interface (for the Request and for the Delivery) 13

14 Modular approach for DR spec. Framework for Retained Data Handover Interface Telephony services Network Access services Asynchronous message services Synchronous Multi-media services e.g. PSTN/ISDN GSM/UMTS-cs SMS/MMS Internet GPRS UMTS-ps webmail chat 14

15 Next on DR ETSI/TC LI will maintain the DR standards Add new internet services as technology progress Add new parameters in line with national requirements ETSI/TC LI can organise an interoperability test, if required ETSI Plugtests for checking the specifications ETSI/TC LI is encouraging widespread use of the DR standards! The use of the Handover standard is already promoted in international conferences and workshops ETSI/TC LI kept a close working relation with the EC/Experts Group The Platform on Electronic Data Retention for the Investigation, Detection and Prosecution of Serious Crime ETSI/TC LI keeps checking related activitiesinotherin groups to liaise, collaborate, avoid duplicate efforts... 15

16 TC LI latest and future technical work Maintenance of LI and DR suites LI and DR Handover Interface specifications Handover from provider to authority 7 parts: service specific specific details for IPdelivery Ongoing new work Specification (TS) on Dynamic Triggering of LI function Two reports (TRs) on LI/DR for Cloud Computing Specification (TS) on handover interface for Warrant information Specification (TS) on X1 internal network interface Specification (TS) on security for LI and DR systems 16
