Cyber workshop at Sandia Labs seeks potential responses to cyberattacks
October 25, 2011 • ALBUQUERQUE, N.M. — Among other dubious achievements, hackers have stolen identities, broken into bank accounts and breached computer systems of military contractors. They could conceivably interrupt water or electricity service to targeted populations. And worse. To solve these problems, Sandia National Laboratories has plans to increase cybersecurity research over the...
