Private sector can take lessons from federal network security projects

Ongoing network security initiatives at the federal level, including the Trusted Internet Connections program and the Einstein project are helping provide a roadmap for the private sector, according to a network security expert. Michael Markulec, chief operating officer of network visualization vendor Lumeta Inc., said the initiatives will likely be used by companies that own network infrastructure at many of the nation's critical infrastructure facilities. In this wide ranging interview, Markulec talks about whether deep packet inspection should be used to root out nefarious traffic, how cloud computing is changing the way companies approach network defenses and whether credit card data can be truly protected using so-called end-to-end encryption. Markulec said good network security still comes down to a basic defense-in-depth approach.
