Notre Dame Expert: Hackers cause Sony major financial, reputational damage

Information security expert John D'Arcy, assistant professor of information technology management at the University of Notre Dame, says this week's hacking attack on Sony Corp. is yet another example of the significant information security threat that affects almost all businesses.

The group of hackers, which calls itself "LulzSec," posted Sony network plans and code, the latest in a string of attacks in the last few months. In April, the Japanese technology and media giant was forced to shut down servers that hosted its PlayStation Network service after it was discovered that it had been hacked and the personal information of 100 million customers had potentially been stolen.

"It seems Sony has become the laughing stock of the hacking community," D'Arcy says. "Sony's damages total more than $172 million, which really speaks to the fact that security is no longer simply a technical issue that should be delegated to IT personnel.
