End-2-End Lawful Interception compliancy and verification
Advancements in communication technology and as a result the increasing complexities in communications systems have fostered the need for advanced LI processes. Some of the communication channels that are majorly intercepted include: VoIP, Email, SMS, images and telephony. It is mandatory for telecom providers to support lawful interception by adhering to the government regulations regarding the same. For Law Enforcement it is critical that they can trust the data provided by telecom providers, while on the other hand for telecom providers it is essential that they can trust the deployed interception technologies in their networks. Automated end-to-end Lawful Interception test tooling would help law enforcement in validating the complete LI chain for all operators and ensures timely detection of non-compliances of telecom providers. For telecom providers end-to-end LI verification tooling would facilitate their compliancy with government regulations.
To help Law Enforcement and Telecom providers, G2K Labs developed LIMA Élite. With LIMA Élite, the complete paths from target interception in the network via the LI Mediation systems at the operators to the Law Enforcement Monitoring Facility (LEMF) are automatically and continuously being tested for each network operator and technology (2G, 3G and 4G). LIMA Élite is operator, network & technology independent and supports the validation of voice calls, SMS and mobile data transfer interceptions, both on metadata (IRI) and content (CC). For Law Enforcement, LIMA Élite can integrate with any LEMF.
LIMA Élite works independently and automatically generates calls, SMS messages and data sessions. The frequency with which this test data is generated is configurable. It will automatically cycle through the available connections, testing all operators and networks in sequence. The SIMs used for generating test calls are being intercepted by the operators. This can be achieved through the normal process of providing warrants for these test numbers. As a consequence all traffic generated by these test numbers is intercepted and delivered to the Monitoring Center. By forwarding the intercepted IRI and CC data on the Monitoring Center to LIMA Élite, the application can verify the correctness of the generated metadata and their contents. In case deviations are detected between the data received and expected, the tool will immediately alert the user, so that corrective measures can be taken. In an operator environment, LIMA Élite integrates with the deployed mediation system(s) and will simulate a LEMF. The LIMA Élite solution consists of a LIMA Élite Backend and a LIMA Élite Target Simulator. A LIMA Élite Target Simulator can handle up to 12 network operators e.g. 12 operators each with a 2G, 3G and 4G network.
LIMA Élite is equipped with an intuitive and user friendly webbased interface giving the user precise control of the operation of the LIMA Élite solution.
