INVESTOR’S BUSINESS DAILY: “The Department of Homeland Security recently warned stock traders and bankers that their online systems may be vulnerable to an al-Qaida cyberattack. DHS should heed its own warning. Remarkably, one of the nation’s most vulnerable networks is run by DHS headquarters, thanks to rapid turnover of cyberchiefs at the young agency. Last October, the inspector general’s office reported that computer systems at the Customs and Border Protection bureau and the Secret Service are vulnerable to unauthorized penetration. Among other things, the DHS-controlled agencies failed to install software that can patch security holes.” That’s comforting.
