Security solutions for the next-generation network

The IT environments surrounding the carrier networks are changing. The communicating individuals and organizations and the contents of their communications have changed and the capabilities of the networks and terminals have improved significantly. These are now built using open technology systems and their roles are also changing in order to become platforms that incorporate various applications. This paper introduces measures required for the carrier networks to deal with the changing environments by categorizing them as four solutions. These include: anti-attack defense, anti-disaster, traffic control and operations management solutions.
