Rationale

Computers and communication technologies have been incorporated into many applications and have fundamentally changed many aspects of the human activities. Unfortunately, the changes have also created new problems, from spyware to steal data, computer viruses and worms to destroy data, to network-enabled weapons, to cyber wars that can disable companies and even countries (such as Stuxnet). All these problems are related to computer security. Due to its paramount importance, computer security is not just one academic research area. Many security products are installed on typical computers; in the United States, there are multiple federal agencies dedicated to computer security; the computer security is a multi-billion industry that is estimated to grow steadily. Computer security related issues have been widely recognized in software development companies. As computer security techniques evolve continuously along with product improvements and new service opportunities, computer security is and will remain to be an important and valuable area in the perceivable future with new career opportunities. Due to the proactive nature of hackers and malicious users and weak links in securing systems (such as phishing email and social engineering attacks target unsuspecting users), it is unavoidable that some computers will be infected by malware and some will be infiltrated and compromised; according to a new study, 38.3% of all users were attacked while their owners were online and in total, 23% of all computers were attacked at least once in 2014. When such activities are sensed, cyber security professionals must act quickly and accurately as shut downing all the servers can affect many normal users while not stopping cyber-attacks as early as possible can have serious consequences in terms of data and other losses. Furthermore, nullifying such attacks can involve many practical cyber security skills that are not covered in security courses. In addition, to prevent such attacks, one may have to understand offensive techniques used by malicious groups. This course is designed to cover the basic principles and techniques for solving cyber-attacks, covering cryptography, web, binary reversing, binary exploitation, forensics, and firmware analysis with the emphasis on practical skill development and problem solving in the context of the cyber Catch-The-Flag (CTF) competitions so that you can develop the skills and techniques that are ready to be used.

Course Description

This course covers fundamental problems, principles, and practical problem solving techniques in cryptography, web, binary reversing, binary exploitation, forensics, and firmware analysis; many of the techniques will be demonstrated and practiced using commonly used and customized tools using Python. It also involves opportunities to solve new CTF challenges and develop new tools to help solve such problems.

Prerequisites

CDA 3100 – Computer Organization I; having a good understanding of instruction set architectures (registers, instruction encoding and decoding, and memory organization) and basic data types, data structures, function calls (calling conventions), and memory layout of programs; be able to understand x86 and other assembly (assuming that instruction reference manuals are available); having a general understanding of computer security.

Course Objectives

Upon successful completion of this course of study, the student will:

Textbook and Course Materials

There is no required textbook for this course and we will provide lecture slides, written notes, and worked out examples from previous relevant CTF competitions. The following books can be helpful to understand some of the basic concepts thoroughly.

Recommended reading: “Hacking: The Art of Exploitation, 2nd Edition” by Jon Erickson: this is a book with accurate and detailed descriptions and commands of common vulnerabilities and corresponding exploits. It is an excellent book for understanding buffer overflow vulnerabilities, string format vulnerabilities, and shellcode, and other exploitation development.

The Web Application Hacker's Handbook: Finding and Exploiting Security Flaws” by Dafydd Stuttard and Marcus Pinto. The book provides a comprehensive and thorough coverage of web security mechanisms, and web vulnerabilities.

Information Security,” 2nd Edition, (ISBN 978-0-470-62639-9), Wiley, 2011, by Mark Stamp. The book provides a good coverage on commonly used cryptographic algorithms and cryptanalysis techniques, and security protocols.

In addition to the textbooks, papers and documents from the literature will be distributed along the lectures.

Student Responsibilities

Attendance is required for this class. Unless you obtain prior consent of the instructors, missing classes will be used as bases for attendance grading. Excused absences include documented illness, deaths in the family and other documented crises, call to active military duty or jury duty, religious holy days, and official University activities. These absences will be accommodated in a way that does not arbitrarily penalize students who have a valid excuse. Consideration will also be given to students whose dependent children experience serious illness. In case that it is necessary to skip a class, students are responsible to make up missed materials. Participation in in-class discussions and activities is also required. All submitted assignments and projects must be done by the author(s). It is a violation of the Academic Honor Code to submit other’s work and the instructor of this course takes the violations very seriously.

 

As this course will cover certain techniques to exploit and break down known systems in order to demonstrate their vulnerabilities, it is illegal, however, to practice these techniques on others' systems. The students will be liable for their behaviors and therefore consequences.

Assignments and Projects

About ten homework assignments (most of them involve solving CTF problems) will be given along the lectures and they need to be done individually and turned in. There will be a term project, where a tool needs to be developed that can help solve a certain family of CTF problems. There will be a CTF competition-style final in the last week of the classes and the write-ups are due during the final exam week.

Academic Honor Code

The Florida State University Academic Honor Policy outlines the University’s expectations for the integrity of students’ academic work, the procedures for resolving alleged violations of those expectations, and the rights and responsibilities of students and faculty members throughout the process. Students are responsible for reading the Academic Honor Policy and for living up to their pledge to “…be honest and truthful and … [to] strive for personal and institutional integrity at Florida State University.” (Florida State University Academic Honor Policy, found at http://fda.fsu.edu/Academics/Academic-Honor-Policy).

 

Assignments/projects/exams are to be done individually, unless specified otherwise. It is a violation of the Academic Honor Code to take credit for the work done by other people. It is also a violation to assist another person in violating the Code (See the FSU Student Handbook for penalties for violations of the Honor Code). The judgment for the violation of the Academic Honor Code will be done by the instructor and a third party member (another faculty member in the Computer Science Department not involved in this course). Once the judgment is made, the case is closed and no arguments from the involved parties will be heard. Examples of cheating behaviors include:

 

v  Discuss the solution for a homework question.

v  Copy programs for programming assignments.

v  Use and submit existing programs/reports on the world wide web as written assignments.

v  Submit programs/reports/assignments done by a third party, including hired and contracted.

v  Plagiarize sentences/paragraphs from others without giving the appropriate references. Plagiarism is a serious intellectual crime and the consequences can be very substantial.

 

Penalty for violating the Academic Honor Code: A 0 grade for the particular assignment /exam and a reduction of one letter grade in the final grade for all parties involved for each occurrence. A report will be sent to the department chairman for further administrative actions. 

Accommodation for Disabilities

Students with disabilities needing academic accommodation should: (1) register with and provide documentation to the Student Disability Resource Center; and (2) bring a letter to the instructor indicating the need for accommodation and what type. This should be done during the first week of class. This syllabus and other class materials are available in alternative format upon request.
