“The strategy you have to undertake is not to seek a perfect defense but to increase dramatically the cost for the attacker so ultimately they look elsewhere instead of trying to attack you,” Lynn said in an interview with In Depth with Francis Rose.
The next step is to extend the level of security at DoD to other government networks, Lynn said.
“Ultimately, we need to develop a public-private partnership to defend our most important critical infrastructure networks,” he said.
2017 is ‘aggressive’ deadline for auditability’
Lynn was DoD’s comptroller from 1997 to 2001 and returned to the department as deputy secretary in 2009. President Obama has nominated Ashton Carter to replace Lynn.
Asked if DoD can be auditable in time, Lynn said, “I think it’s very aggressive but we have a plan to make it.”
Skepticism that DoD can make this goal is “certainly well-rooted,” he said.
DoD is a “massive enterprise” that must coordinate its money flow with different systems.
