New computer network security threat identified

 

       

Virtualization, which allows multiple operating systems, or "virtual machines" and their applications to share one physical server, has been possible for decades, but live virtual machine migration is relatively new.

It allows individual virtual machines to migrate among several servers throughout the day with little service downtime, equalizing the load on the servers as it fluctuates. The security of live virtual machine migration has not been studied extensively, but the set-up is common in large companies today.

Hackers could intercept data and compromise the integrity of a virtual machine's operating system during live migration, said Jon Oberheide, a doctoral candidate in the electrical engineering and computer science department. The most popular software doesn't encrypt the information as it travels from server to server.

 
 

UK orders broadband future review

 

        The government has said it will review the future of broadband internet in the UK amid calls that it should help firms pay for installing new infrastructure.

It said it wants a better understanding of how to pave the way for moving to "next generation broadband networks".

The review will be carried out by the former chief executive of telecoms firm Cable & Wireless, Francesco Caio.

An increasing number of consumers and firms are using broadband services and new, high-capacity cables are needed.

'Prepare the way'

The review has been ordered by the Department of Business, Enterprise and Regulatory Reform.

According to the industry, the current telecoms infrastructure cannot cope with the increase in demand for services such as downloads of films, videos and music.

The review will report back to ministers and Chancellor Alistair Darling in the autumn.

"We need to prepare the way for the UK to adopt groundbreaking new technologies to ensure that we do not get left behind - competitively or technologically," said Business and Competitiveness Minister Shriti Vadera.
