The $19 billion for cybersecurity in the President's budget represents a 35% increase over the prior year's enacted spending. The biggest piece of the increase is a new $3.1 billion Information Technology Modernization Fund, which is a down payment on the comprehensive overhaul of Federal IT systems that must be undertaken in the coming years. It's a revolving fund that will enable agencies to invest money up front and realize the return over time by retiring, replacing, modernizing antiquated IT infrastructure, systems, and networks that are expansive to maintain, provide poor functionality, and are difficult to secure.
