Sample Questions for Midterm Preparation:   SAMPLE MIDTERM QUESTIONS – Click Here.


Individual Research Essay:

            Each student will write and submit an essay that involves research into a specific topic in Networks and Security.  This topic may form the basis for the in-class Presentation (see below) if the student chooses, or it may be completely independent.  Students must submit their topic choice to the Instructor for approval before beginning work.  The essay should be between 10-15 pages in length using the IEEE format for writing papers for conferences (using Word).  Proper citation style and formatting must be used.  All essays must be written by the student in their own words (except when quoting other authors, with citations).  The essay will be submitted by email to the Instructor.


Individual Presentation:

            Each student will give a Presentation in the regularly scheduled class at a time and date to be determined by the class and Instructor.  The topic must be approved beforehand by the Instructor.  The presentation must be 13-15 minutes in length, including a few minutes for questions and answers from the class.  The presentation slides must be submitted by email to the Instructor immediately following the actual presentation in class.  Note that the topic may be the same as the Research Essay (see above).


Projects I and II (Groups):

            Two of the assignment exercises below must be completed as two projects, I and II respectively, undertaken by a group.  Students are expected to work in groups of up to 3 members.  The practical experience offered through these exercises is considerable and excellent learning can be achieved through doing the work, both independently and in a group.  Note that each assignment is provided as a .zip file.

            Each group must submit a detailed report on each chosen Assignment (from the list including 1 to 5 below), listing their group members and the progress made on the assignment questions and goals.  It is expected that most of the questions and goals described will be achieved, but not necessarily every question or goal.  All group members will receive the same grade.

            All students should read the textbook where these exercises are described.  Additional informational resources may be available on the publisher’s website for the textbook.  For added resources, the textbook describes where to go to on the web to find what you may need.  Note that all practical aspects of the assignment work must be adapted to our local environment with unique examples provided – screen shots of activities on remote websites will not be accepted, in general.

Policy on cheating:

The professor and teaching assistant for 60-367 will put a great deal of effort into helping students to understand and to learn the material in the course.  However, they will not tolerate any form of cheating.


The professors and teaching assistants will report any suspicion of cheating to the Director of the School of Computer Science.  If sufficient evidence is available, the Director will begin a formal process according to the University Senate Bylaws.  The instructor will not negotiate with students who are accused of cheating but will pass all information to the Director of the School of Computer Science.


The following behaviours will be regarded as cheating (together with other acts that would normally be regarded as cheating in the broad sense of the term):


·         Copying assignments

·         Allowing another student to copy an assignment from you and present it as their own work

·         Copying from another student during a test or exam

·         Referring to non-approved notes, textbooks, etc. during a test or exam

·         Talking during a test or an exam

·         Communicating with another student in any way during a test or exam

·         Having access to the exam/test paper prior to the exam/test

·         Asking a proctor for the answer to a question during an exam/test

·         Presenting another person’s work as your own

·         Using web resources and information without proper referencing and quotation indicators

·         Modifying answers after they have been marked and attempting to use those to support an appeal

·         Any other behaviour which attempts unfairly to give you an advantage over other students in the grade-assessment process

·         Refusing to obey the instructions of the officer in charge of an examination.
