Using structured metadata in IoT systems enables ________-based searches that identify objects of interest based on specific properties.

________ systems rely on a set of known signatures of events to identify suspicious behaviors.

Main memory and disk space are considered as _____ of physical database design.

A(n) ________ is a hardware-assisted segregated secure environment that provides secure storage of encryption keys and dedicated storage and execution of security code.

5.  (10 points).  In class we talked about the steps required for determining a structure using X-ray diffraction. Answer the questions below about X-ray structure determination. a.    (2 points). Why are crystals used for diffraction experiments rather than a single molecule, which in principle could diffract an X-ray? b.    (2 points). Describe Bragg’s law and why it allows for one to see reflections (i.e., a diffraction pattern). c.    (2 points). Why are Miller indices useful for describing an X-ray diffraction experiment? d.    (2 points). Describe the setup for an X-ray diffraction experiment and how one would collect data. e.    (2 points). What is the “phase problem” in X-ray crystallography and describe one method that allows one to solve the phase problem.

How did the Stuxnet worm infect target computers?

The ________ is the collection of points of potential system security exposure.

Privacy and confidentiality have always been a major concern in legacy industrial and manufacturing systems due to their inclusion of Internet-enabled functional overlays from the point of their initial design.

A good design practice is to avoid dividing networks into segments based on physical connectivity and device similarity.

An IoT framework can be implemented on a partial basis; systems do not need to adhere to all of its parts.
