BlackBerry has gained a reputation in the mobile space during the past decade or so as the "most secure" handheld device and mobile platform available. That's largely due to RIM's BlackBerry Enterprise Server (BES) software for corporate e-mail deployments, which has earned high-level security certifications from some of the world's most demanding information-security organizations, including the U.S. National Institute of Standards and Technology (NIST); Canada's Communication Security Establishment (CSE); and the U.K.'s Communications Electronic Security Group (CESG), among others. That's all fine and good for corporations looking to secure infrastructure and resources associated with their BlackBerry deployments. But no amount of security certifications can make up for an uninformed and/or careless BlackBerry user.
