Worldwide, countries and businesses will have to come together to ensure the safety of commerce over the Internet and find ways to combat cybercrime and cyber terrorism. We are taking a number of steps to prevent future breaches, including enhanced levels of data protection and encryption; enhanced ability to detect software intrusions, unauthorized access and unusual activity patterns; additional firewalls; establishment of a new data center in an undisclosed location with increased security; and the naming of a new Chief Information Security Officer.

Yes, we believe so. Sony Network Entertainment America is continuing its investigation into this criminal intrusion, and more detailed information could be discovered during this process.

Some users claimed to be able to use Netflix's streaming service  but others were unable. Sony also mentioned the possibility that credit card data was taken—after claiming that encryption had been placed on the databases, which would partially satisfy PCI Compliance for storing credit card information on a server.

Your statement indicated you have no evidence at this time that credit card information was obtained, yet you cannot rule out this possibility. Please explain why you do not believe credit card information was obtained and why you cannot determine if the data was in fact taken.

Our forensics teams have not seen the queries and corresponding data transfers of the credit card information.
