ITU’s work in
radiocommunication standardization continues, matching the
constant evolution in modern telecommunication networks. ITU
established fundamental security principles for IMT-2000 (3G)
networks (Recommendation ITU-R M.1078 and Recommendations ITU-R
M.1223, ITU-R M.1457 and ITU-R M.1645 are also relevant).
ITU has also issued ITU-R Recommendations on security issues in
network management architecture for digital satellite systems (Recommendation
ITU-R S.1250) and performance enhancements of transmission
control protocol over satellite networks (Recommendation ITU-R
S.1711).
