MSIT 458: Information Security and Assurance

Winter 2015

Yan Chen

I.  Course description:

The past decade has seen an explosion in the concern for the security of information. This course introduces students to the basic principles and practices of computer and information security.  Focus will be on the software, operating system and network security techniques with detailed analysis of real-world examples. Topics include cryptography, authentication, software and operating system security (e.g., buffer overflow), Internet vulnerability (DoS attacks, viruses/worms, botnets, etc.), intrusion detection systems, firewalls, VPN, Web and wireless network security. 

II. Required text and/or other materials:
III.  Reference text and/or other materials:
IV. Required prerequisites or knowledge base
V. Rationale for inclusion in MSIT Program:

This course provides students with an extensive understanding of information security management with emphasis on network security. Whereas other courses provide an overview of the basics of the discipline, information security is simultaneously a technical and managerial discipline with enterprise-wide implications for employees, operations and systems at every level. For organizations to successfully implement and manage an effective and efficient security program while managing shifting risks associated with interrelated information technology and decision-making employees, contractors, vendors, and suppliers must understand the concepts, technologies and practices of information security and be able to apply them effectively in their own distinctive areas of responsibility.

Course goal: VII. Course Objectives:
Upon successful completion of this course, the student should be able to:

X. Assignments
There will be several group-based homework assignments so that students can reflect on what they learn in each class and try to apply them. In the beginning of each class, we will discuss the homework as warm-up. 

In addition, students are expected to engage in technical paper reading, and writing summaries. These papers are carefully selected (with little math!) which can be understood with the basic information security and networking knowledge.   Each group is expected to briefly present their findings and takeaway of the papers.

Your summary should include at least:

Project: each group will work on a quarter-long project called Information Security in Real Business with the following steps.
Part 1: Understanding the security issues and requirements in your corporate/organization, using the four cornerstones of secure computing introduced in the class.  For each of the cornerstone, select one (or more) issue(s) and compare how that was handled in different corporates/institutes of each team member, and what remains to be done to fully satisfy the security requirements.  If you are uncomfortable talking about your employers security practices, you can anonymize the name or use a hypothetical case but reflects the real problems in industry.  The requirements do not (and probably should not) to be restricted to the technical ones, but can be related to legal, business, social, or anything to do with information security.   In the submission, please also give suggestions on the current syllabus, e.g., important topics which are currently missing, interesting extra teaching materials that you are aware of, etc. I will try to make adjustment based on the suggestions. The suggestion part is optional. It will not affect your grade if you don't have any.

Given there are increasing number of full time students who do not have employers, it is a group assignment now.  But each group needs to submit two case studies for two different companies.  In each case study, you are expected to analyze the four cornerstones.   The report should be in Word or pdf.
The format should be something as follows:

Company 1: general introduction

Security analysis: (write a paragraph for each of the points below)
1.    Confidentiality:
2.    Authenticity:
3.    Integrity:
4.    Availability:

Issues identified:

Company 2: general introduction

Security analysis: (write a paragraph for each of the points below)
1.    Confidentiality:
2.    Authenticity:
3.    Integrity:
4.    Availability:

Issues identified:

Part 2:  From the (at least) four issues, pick the most interesting one to your group and the one which should not been very well solved (or the one being solved, i.e., an ongoing project) in your corporates/organizations.  Formulate a security problem and do some research on the related work. Please show why this problem is a general one that comes across multiple industry/education/government sectors. Each group is expected to give a presentation (5-10 minutes) to seek synergy and early feedback from other students and the instructor in week 5.

Part 3:  Then please analyze the pros and cons on the existing work, and propose a solution to the problem you formulated, by either adopting existing solutions, or propose something new. Please be specific on how you will implement or have implemented the solutions (down to the product level), the cost/risk analysis, feasibility analysis, business/legal consequence, how this solution will fit different corporate context, like industry, education, government, etc. Each group is expected to give a final project presentation towards the end of the quarter.  The presentation is expected to be 20 minutes plus 3 minutes Q&A. But we can have Q&A mingled w/ the presentation, i.e., each team has 23 minutes, including the switch time.

Note: all homework are due by the 11:59pm of Thu. night.  Email only presentations to me and email all other homework (project part 1, paper summary and homework) to
