CIS 6930 - Cellular and Mobile Network Security Introduction Professor Patrick Traynor 8/23/2018 Florida Institute for Cybersecurity (FICS) Research
Rapid Communication Over Distance Florida Institute for Cybersecurity (FICS) Research 2
Modern Smoke Signals We have come to take the presence and availability of cellular • networks to be a given. When was the last time you were somewhere without • coverage for an extended period of time? For something you rely upon every day, • what do you really know about these networks? Why is now the right time to start • investigating security issues facing these devices and infrastructure? Florida Institute for Cybersecurity (FICS) Research 3
Why Do I Need This Course? As engineers and scientists, you need to underpinning of our global • communications networks. With this information, you will be able to help design and implement the • next generation of networked systems and applications. As virtually every person on the • planet “comes online”, you need to understand the implications and architecture of these systems. Florida Institute for Cybersecurity (FICS) Research 4
Goals My Goal: To provide students with the tools to evaluate the security of current and • evolving cellular and mobile systems. Cellular Networking Fundamentals • Recognize trade-offs between different technologies. • Develop research resulting in a conference publication. • Prepare you for advanced research in this area. • This is going to be a hard course. The key to success is sustained effort. Failure to • keep up with readings and project will likely result in poor grades, and ultimately little understanding of the course material. Florida Institute for Cybersecurity (FICS) Research 5
Caution Networking and Security courses tend to have a lot of acronyms. • Jargon makes communicating complex concepts and relationships simple • for those working in the area. Telephony takes acronyms to a whole new level. • Think nested acronyms, multiply defined acronyms • (depending on the portion of the network), etc. I usually do not stress memorization, but • some amount is necessary here to survive! Florida Institute for Cybersecurity (FICS) Research 6
What Topics Will We Cover? This course is a systems course covering general topics in computer and • network security. We will investigate the tools and problems of contemporary security. Topics will include: Wireless basics, spectrum issues, core network architectures (GSM, • ISDN, IMS, SIP), air interfaces (GSM, 3G), mobility management, authentication between devices and the network, end-to-end authentication, congestion and denial of service, privacy and eavesdropping...

You need to understand ... IP Networks • Basic Security Constructions and Issues • Modern Operating Systems • Advanced Mathematics • Basics of systems theory and implementation • E.g., Distributed systems, networking, operating systems, • Florida Institute for Cybersecurity (FICS) Research 8
Who should NOT take this class? Students without the necessary background courses. • Students who have poor judgement. • Students who are not willing to put forth significant effort. • Students who are not interested in learning. • Students interested in doing harm to people, property and infrastructure. • Florida Institute for Cybersecurity (FICS) Research 9
Course Materials Website - I am maintaining the course website at • https://www.cise.ufl.edu/class/cis6930fa18cmn/ • Course assignments, slides, and other artifacts will be made available on • the course website. Course textbook • . McDaniel and T. La Porta. Security for P . Traynor, P • Telecommunications Networks . Springer, Series: Advances in Information Security, August, 2008. ISBN: 978-0-387-72441-6.

Course Calendar • The course calendar as all the relevant readings, assignments and test dates • The calendar page contains electronic links to online papers assigned for course readings. Please check the website frequently for • announcements and changes to the schedule. Students are responsible for any change on the schedule ( I will try to make announcements in class ). Florida Institute for Cybersecurity (FICS) Research 11
Grading • Grading in this class will be distributed as follows: 50% Course Research Project 15% Assignments 25% Mid-term Exam 10% Class Participation I reserve the right to give “Unannounced Learning Experiences”. • You get the grade that you earn, so be sure • that you earn a grade you like. Florida Institute for Cybersecurity (FICS) Research 12
Assignments, Quizzes, Reviews • Assignments: Practice Exam Questions Conceptual Questions (Basic and Complex) • Constructions • Precise Answers • • Review of Papers (for each class) Define Concepts • Comparison with Other Approaches • Details of Approach • • Written and Oral Reviewing Are Important Florida Institute for Cybersecurity (FICS) Research 13
Readings There are readings in this course covering various topics. These • assignments are intended to: Support the lectures in the course (provide clarity) • Augment the lectures and provide a broader exposure to security • topics. Students are required to do the reading! • About 10-20% of questions on the tests will be off the reading on topics that • were not covered in class . You better do the reading or you are going to be in deep trouble when it comes to grades. Florida Institute for Cybersecurity (FICS) Research 14
Lateness All assignments are due at the beginning of class. • Submit everything via Canvas, please! • Late assignments are assessed a 15% per-day late penalty, with a maximum • of four days. Students with legitimate reasons should contact the professor before the • deadline to apply for an extension. Unless the problem is apocalyptic, don’t • give me excuses.

Course Project • End Result: Research Paper Motivation for an Experiment • Background • Related Work • Experimental Approach • Experimental Evaluation • • I will provide sample topic areas General Areas... but you should be thinking about it already • • Start with an Existing System/Approach Break It • • Improve It Aim for a Research-Quality Result • Florida Institute for Cybersecurity (FICS) Research 16
Ethics Statement • This course considers topics involving personal and public privacy and security. As part of this investigation we will cover technologies whose abuse may infringe on the rights of others. As an instructor, I rely on the ethical use of these technologies. Unethical use may include circumvention of existing security or privacy measurements for any purpose, or the dissemination, promotion, or exploitation of vulnerabilities of these services. Exceptions to these guidelines may occur in the process of reporting vulnerabilities through public and authoritative channels. Any activity outside the letter or spirit of these guidelines will be reported to the proper authorities and may result in dismissal from the class and or institution. • When in doubt, please contact the instructor for advice. Do not undertake any action which could be perceived as technology misuse anywhere and/or under any circumstances unless you have received explicit permission from Professor Traynor.

A Note on Academic Integrity As scientists and engineers, we must trust each other to make progress. • Numerous examples exist to show the consequences of this breakdown. • Jan Hendrik Schon... • Academic dishonesty, whether from cheating , copying , fabricating results or • through any other dishonest practice will not be tolerated. I take this personally - you should too. • Florida Institute for Cybersecurity (FICS) Research 18
Next Time... Security Basics • Read Traynor et al Chapter 2. • Remember, you need to read it BEFORE you come to class! • Start thinking about ideas for your semester project. • Florida Institute for Cybersecurity (FICS) Research 19
