Strengthening network security
The events of 11 September 2001 have made security a focus for governments, corporations and individuals.
To this end, ITU has been at the forefront of the development of standards that will help to make the world a safer place.
ITU’s standards development sector, ITU-T, has developed the de facto standard for electronic authentication over public networks
ITU-T X.509. X.509 is the definitive reference for designing applications related to Public Key
Infrastructure (PKI). The elements defined within X.509 are widely used, from securing the connection between a browser and a server on the Web to providing digital signatures that enable e-commerce transactions to be conducted with the
same confidence as in a traditional system. Work continues on developing security standards in IP networks,
ITU-T H.323 and mobile security issues for next-generation networks. Specifically, ITU study groups have looked at the following issues:
- Security from network attacks
- Theft or denial of service
- Theft of identity
- Tele-biometrics for authentication
- Security for emergency telecommunication
- Telecommunication networks security requirements.
