Should books discussing computer security/exploits be banned? How about all those books about rootkits that populate the shelves at Barnes and Nobles or Borders? What about the books talking about defeating WEP/WAP-enabled encryption on wireless routers?
Under your logic TKjunkmail, these are just as bad.
However they serve a helluva good purpose...they provide the information necessary for system administrators to ensure that as many vulnerabilities are assessed and addressed for their networks as is possible.
Don't bash a book because it contains information that can be used as an exploit. Anything can be used in a negative manner in life... -- Beer is proof that God loves us and wants us to be happy
These books also inform the reader of the actual fact of things. If a company was lying to you saying that the service is secure yet there was a high rate of identity theft. Nobody would really know it's the encryption of the wireless routers which is failing. These books exploit facts of these wireless technologies that inform the reader and then everybody will know where the problem is occuring and avoid such products.
