This week on Cyberspeak, Ovieâs Invisible Shield came in for his blackberry and he loves it. We discuss US v Boucher and the Fifth Amendment protection not to be compelled to disclose passwords. For some great reading on the issue, check out Susan Brennerâs blog post. Department of Defense considers cutting off all non-official Internet access.   We discuss whole disk encryption and new advertised features in True Crypt V5.  We discuss Nuix, a new forensic utility with special application for analysis of emails.  Do you encrypt you forensic images before transport?  Ovieâs Web site pick of the week is http://www.bureauofcommunication.com/compose/apology and Bretâs is Hackers Diet.
