<i>BlackBerry's mail system "is known to be very secure". Known by whom, exactly. Can you cite a source? Any source? I'm an expert in cybersec, I know lots of experts, and I nobody I know thinks...</i><p>The author puts his credibility on the line dismissing RIM's security as obviously flawed, and then admits he hasn't the most basic clue about their services. Of course BES and BBM are (or: were at one stage) secure enough that the Indian government threatened to shut down RIM, if they did not provide a direct link the servers for Indian security forces.<p><i>Update: @ChrisEng points out that there's a difference between normal BlackBerry Internet Services (BIS) provided by your phone carrier, and BlackBerry Enterprise Services (BES) provided by your company.</i><p>_______<p>The relevance of BES:<p><i>What is key here, is that when running a BES neither RIM nor the wireless carrier can assist law enforcement in accessing email, Internet browsing (which can be encrypted by default) or BlackBerry messenger contents (assuming that the organization isn’t using the same global encryption key consumer messenger traffic relies on). If the BES and surrounding corporate IT infrastructure is outside a country’s legal reach then secured communications can be provided without worrying about government actually going after the mail or messaging servers themselves. Further, if a corporation’s legal assets and identity are also outside the nation, the government may be unable to legally compel the company to turn over the contents of BlackBerry communications. Needless to say, the full encryption of communications prevents the nation’s wireless carriers from effectively tapping BlackBerry device communications.
