Hi there. In this video, I want to briefly go into how the peer review
assignments in this course will work before you get started on that aspect. First, let's talk about what
peer review assignments are, since some of you
may be new to them. As you can imagine, in a massively open
online course like this one and the rest of
the courses on Coursera, it's really impossible for
me or any instructor to grade and provide adequate
feedback on your assignments. There's just too many of you. As you may have seen with our quizzes already for example, those all have been preprogrammed with not only the correct answer, but feedback indicating why
particular answer is right or wrong or what video you should review to arrive at
the correct answer. Peer review assignments
are Coursera's way for you to practice
a real-world activity. For example, something that you might do as part of your job, and get some real feedback
from other humans instead of preprogrammed
feedback like with our quizzes. It's great way to balance
our desire as learners, to get some real constructive genuine feedback from someone else with the practicalities of such a giant online
course structure. Now to do this effectively, there are some guidelines
that I've developed for all reviewers in the form
of a grading rubric. This rubric will reflect the requirements that
have outlined for each of the assignments and
will basically ask your fellow learners to
score how well you've met a requirement or provide additional written
feedback on what you did well or could improve, based on their understanding of the material of the course. Basically, as long as you follow the requirements as outlined in the assignments,
you should do great. Then you, in turn will review
some of your peer's work. Reviewing another peer
is not optional as this reviews are necessary for you to receive your own grade. Now before we move on to talk about the actual assignments, I just want to remind you to
be kind in your feedback. That doesn't mean you can't
be critical of course. Just remember to be constructive and supportive of
your fellow learners. We're all here to learn and we're all in a different place. So, just keep that in mind. Please, do take
this part seriously. Now let me give you a brief overview specifically about the assignment
for this module. You will create a threat model
of a voting system. You will need to look at the existing system
specifications and formulate a system diagram, create a data flow diagram and then determine
trust boundaries. Finally, you will apply the STRIDE method to find at least three threats
to the system. The main thing is to
be able to justify why you set up your data flow diagram
the way that you did, and to be able to justify the trust boundaries and
your three system threats. Don't worry, I have provided more step-by-step instructions in the assignment itself. Good luck.
