I understand the need for securing these types of networks, but one of the may costs of allowing the government to control private network security is the privacy issue, which is brought up in the last paragraph of the article.
Blair acknowledged there will be privacy concerns about centralizing cybersecurity, and he said the program should be designed in a way that gives Americans confidence that it is "not being used to gather private information."
I don't like it. It's another encroachment on private property and privacy for the "national security." Besides, don't the entity's that own and operate these networks have incentive to protect their investment? Why would the government be any better at developing cyber-security than the private sector?
