Last Friday I attended an excellent cyber security event sponsored by Neustar, who deliver some of the vital services that enable the Internet to function securely. I was particularly impressed by an eye-opening presentation by Rodney Joffe, Neustar’s Chief Technologist, on DNS security. Ensuring business traffic is secure over the Internet demands a lot more than we might think. Enterprises are exposed to many underlying risks of espionage and modification of data in transit. Threats of IP hijacking are a real and present danger. All security managers should make it their business to understand the potential security risks associated with the Internet. We are entering a decade that is likely to be dominated by large-scale compromises of business information and services.
