IBM has bought over 12 different security type tech companies recently! The interesting thing is is that in this article , the purchased company was a partner with IBM and doesn't do security which would affect the general public but it's focus is internal security! I don't think that anyone has discussed this part of security yet!? It probably is as wide ranging as any other type.

vic :) imo
