IT pros braced for the release of Apple's long-awaited iPhone, unsure what kind of security impact the device would have. A number of security experts said the iPhone would be a major data-security problem, while others indicated that IT professionals have more pressing matters to be concerned with. Scott Charbo, chief information officer of the U.S. Department of Homeland Security (DHS), was grilled by a Congressional subcommittee on how well the department could fight off a cyberattack. The interrogation came weeks after a critical Government Accountability Office audit stated that the DHS suffered 844 cybersecurity incidents in the past two years.
