The US President Barack Obama has just announced the plans to carrying out those security arrangements for the American computer networks. He said that from now on, America’s digital infrastructure would be treated as a strategic national asset, which is the right way of doing things. He has also announced the creation of cyber security office which will be set up in the white house. Mr.Obama will personally take the responsibility of appointing the person who will take care of this arrangement in the white house.
