How to make Internet more secure?

[Commentary] We must be mindful that the Internet is vulnerable to exploitation and attack. Those vulnerabilities increase every day as more and more activity finds its way onto cyberplatforms. Clearly, the Internet must be made more secure, but in a manner that does not infringe on our constitutional rights to receive information and express views.

Last year, Sens. Joe Lieberman (I-CT), Tom Carper (D-Delaware) and I introduced legislation to strengthen the government’s efforts to safeguard U.S. cybernetworks from attack and prevent presidential overreach. That bill was unanimously approved by the Senate Homeland Security and Governmental Affairs Committee. Last month, we introduced a new version with stronger, more explicit provisions that would prevent the president from ever shutting down the Internet. It would also provide an opportunity for judicial review of designations of our most sensitive systems and assets as “covered critical infrastructure.”
