The course requires sufficient programming knowledge, system knowledge, and immense interest in understanding cyber security and cyber defense. So please decide whether you would like to consider this.

 

Mode of offering

This time this course will be offered as a "flipped class room" mode. In this mode, module-wise lecture sessions will be recorded and uploaded on the mooKIT platform of Professor Prabhakar every week.

You will have to listen to the lectures before coming to class once a week where you will be doing various hands on exercises, answer quizzes, or discuss issues. The assignments will be in the form of attacking cyber-vulnerable systems given to you in a sand box and you will have to first find the vulnerabilities by attacking, then fix the systems, and then again check with the same attacks if the fixes are working. This can get intense, but it is also a lot of fun.

Any kind of plagiarism or unethical cooperation will be highly discouraged and  will be ground for deregistration from the course and possible stricter action as per guidelines. 

Timing

Thursdays 9-10:15 AM will be the weekly meeting but you will need to listen to the lectures online before coming to class. You will be tested on that.

Syllabus

 Major, Measurable Learning Objectives

 Having successfully completed this course, the student will be able to:

  • Discover software bugs that pose cyber security threats, explain and recreate exploits of such bugs in realizing a cyber attack on such software, and explain how to fix the bugs to mitigate such threats
  • Discover cyber attack scenarios to web browsers, and web servers, explain various possible exploits, recreate cyber attacks on browsers, and servers with existing bugs, and explain how to mitigate such threats 
  • Discover and explain cyber security holes in standard networking protocols, both in network architecture, standard protocols (such as TCP/IP, ARP, DNS, Ethernet, BGP etc), explain mitigation methods and revisions of standards based on cyber threats.
  • Discover and explain mobile software bugs posing cyber security threats, explain and recreate exploits, and explain mitigation  techniques.
  • Articulate the urgent need for cyber security in critical computer systems, networks, and world wide web, and explain various threat scenarios
  • Articulate the well known cyber attack incidents, explain the attack scenarios, and explain mitigation techniques
  • Explain the difference between Systems Cyber Security, Network Cyber Security, and cryptography, crypto-protocols etc.
  • Articulate the cyber threats to critical infrastructures

Prerequisites and Co-requisites

Prerequisites for this course is a very strong programming background with knowledge of program run-time environment, usage of debuggers, and knowledge of shared libraries or dynamically linked libraries. Some knowledge of x86 assembly language or similar assembly language will be assumed. Some knowledge of Operating Systems especially memory management, virtual memory etc will be assumed. We will also assume that the student knows basic network protocols such as TCP/IP, DNS, routing etc. We will further assume  that the student is familiar with a client/server architecture of the world wide web -- where browser is a client to a web server. Further, prior knowledge of a scripting language such as shell scripting, perl, python and/or Ruby will be beneficial. Knowledge of Javascript, PHP or other web programming might be very useful.  Prior familiarity with preliminaries of cyber security would be helpful but not required.  

A quiz will be administered in the very first class in the beginning. The quiz will help you determine your standing with respect to above mentioned prior knowledge. 

Texts and Special Teaching Aids

There is no specific text. We will provide all material via moodle. When the class moodle website will be up, each student should immediately register him/herself for this class on moodle. Most communications, assignments, course material will be only available via moodle. So it is extremely important that all students must be on the course moodle site.

Grading

Semester grades will be based on the following weights:

Attendance & In-Class Exercises

20%

(including pop quizzes)

Projects & Assignments

60%

(10% each for 6 assignments and projects)

Midterm Exam

10%

 

Final Exam

10%

 

 

Semester grades will be determined after all work is completed and graded.  Point ranges for letter grades will be based on a several factors, including absolute and relative performance.  Letter grades will not be based on a fixed, predetermined curve or point range.    

Unless otherwise stated on the class all graded assignments must be submitted by 11:55 pm   on the specified due date.  There will be a 10% penalty for each 24 hour delay in submitting an assignment.   

If you feel that an error is made in grading an assignment or an exam, you must present a written appeal within one week after the assignment or exam is returned to you.  Verbal appeals are not allowed and grades will not be changed after the one week period.  Your appeal should be specific.  Submit all appeals to the instructor.
