As day four of the RSA Conference continues, attendees found still more to talk about on Twitter. Among the topics:
1. The Internet of Things is opening a whole new set of complications.
2. Medical devices are part of it.
3. Why hacking back is a bad idea. (Hint: Legalities.)
4. Sometimes you pull one string and unravel a whole ball of twine.
5. Divine intervention is a two-edged sword.
