The threat environment has changed rapidly, and what we once thought of as theoretical is now a reality. Things we thought couldnt be secured, or didnt need to be secured, are now essential to a secure environment.

Critical infrastructures were not a major concern for most until Stuxnet hit and left organizations scrambling. Now, with the explosion of embedded devices, were seeing an explosion of threat vectors. We must secure all of these, while the bad guys only need to find one way in.
