President Barack Obama on Monday ordered a 60-day review of the nation’s cybersecurity to examine how federal agencies use technology to protect secrets and data. Obama planned to have former Bush administration aide Melissa Hathaway head the effort, a senior White House official said. The official spoke on the condition of anonymity because an announcement had not yet been made. The government manages, compiles and protects massive amounts of data — everything from passport application to tax records, personal tax returns to national security documents.
