The present document provides an overview of Cloud/virtual services and studies. This includes Lawful Interception (LI) and Retained Data (RD) aspects of these services in the converged Cloud/virtual service environment, the challenges and obstacles of complying with those obligations, what implementations can be achieved under existing ETSI LI standards and what new work may be required to achieve needed Lawful Interception capabilities.

Cloud Services, in whichever forms they take (Infrastructure, Software, Platform or combinations of these), are often trans-border in nature and the information required to maintain LI and RD capability or sufficient coverage for LI/RD support may vary in different countries or within platforms of different security assurance levels. The present document aims to ensure capabilities can be maintained while allowing business to utilize the advantages and innovations of Cloud Services and was undertaken cooperatively with relevant Cloud security technical bodies.
