we try to stop, not only infiltration, but exfiltration, where sewage would actually leak out of the pipe. the head is larger, so it breaks away the old pipe and allows the new pipe to come in behind it. griffin: we are saving about 67% of the cost of actually digging old pipe up. clyne: it's less invasive than an open-cut process, where you would open the whole trench up and replace the pipe. it's called "trenchless" technology, so... that's as good as it gets. griffin: we don't have to dig up everyone's yard, and we refurbish that pipe at a much-reduced cost. another technique, the cured-in-place lining. it's equivalent to putting a large sock through the existing sewer. we form a new pipe inside the old pipe, and therefore we seal up all of the defects that allow rainwater to come in. hunter: we repair about 730 leaks a month in our system. griffin: the improvements that we've made will make the environment better. we had approximately 1,000 overflows occur in 1999. today, we've reduced overflows by 45% to 50%. and it's going to continue to improve as we go forward with the rehabi

so, i really, the concern really should be the exfiltration of data from our government, from our cleartractors, from all of our manufacturing, organizations and u.s. commercial space writ large. that to me is a long-term problem for the united states in terms of our competitive advantage and our ability to compete at a national level or an international level economically. that's a significant impact. ashley: is there any way we can totally prevent this. or is this something we have to try to keep up with and try to prevent as best as possible? >> the most significant, most substantial attackers are going to get on a network. our networks are so vast. they ride on inherently insecure infrastructure which is the internet. it is really important for us to identify and detect when these attacks occur, and infiltrations occur and look to mitigate the consequences from these attacks. right now, the risk to foreign governments, when they steal this data is pretty close because there is no impact on them. ashley: right. >> the benefit is substantially high. until we invert that, that mathemat

increasingly adept at exploiting weaknesses in our computer networks, and once inside they can exfiltrate the state secrets and trade secrets. and we also faced persistent threats from hackers for profit, organized criminal cyber syndicates, and activist groups. as i said in the past, i believe that the cyberthreat may well eclipse the terrorist threat in years to come. and in response we're strengthening our cyber capabilities in the same way we enhanced our intelligence and national security capabilities in the wake of september 11 attacks. the cyber division is focused on computer intrusions and network attacks. fbi special agents work side-by-side with federal, state and local counterparts on cyber task forces in each of our 56 field offices, working to detect and disrupt computer intrusions. we have increased the size and scope of the national cyber investigator joint task force, which brings together 19 law enforcement, military and intelligence agencies to stop current attacks and prevent future attacks. and together with dhs and nsa, we have clarified the lanes and roads for our c
