CSE 484 / CSE M 584 Computer Security University of Washington Autumn 2021 This course covers a wide range of computer security topics, including software security, cryptography, web security, malware, and physical security. It encourages a "security mindset" while requiring a firm understanding of computer science fundamentals and command-line Unix development environment. In this course, we will cover topics including: the "security mindset", threat modeling, software security, cryptography, malware, web security, web privacy, smartphone security, authentication, usable security, anonymity, physical security, and security for emerging technologies.  *CSE 332* and *CSE 351*

You should have maturity in both the mathematics of computer science and in the engineering of computer systems. This means that you should: have a good understanding of data structures and algorithms; be comfortable writing programs from scratch in C and Java; be comfortable writing and debugging assembly code; and be comfortable in a command-line Unix development environment (gdb, gcc, etc). You should also have a good understanding of computer architecture, operating systems, and computer networks. Most importantly, you should be eager to challenge yourself and learn more! ### No Textbook

In previous quarters we've used "Foundations of Security: What Every Programmer Needs to Know, Daswani, Kern, and Kesavan, ISBN 1-59059-784-2. This quarter we are not using an official textbook, and are instead using various freely available readings.
We will be using some readings from [Security Engineering](https://www.cl.cam.ac.uk/~rja14/book.html) of which the 2nd edition is freely available on the author's webpage

CS1660: Computer Systems Security Brown University Spring 2022 CS1660 delivers a balanced mix of theory and practice in computer systems security. Starting with the foundational aspects of cryptography, the course navigates through security aspects of web applications, operating systems, and networks. Students will hone their "security mindset," learning to identify vulnerabilities and understand defenses across different domains. CS1660 (formerly called CS166) is a course on **computer systems security** through a balanced mixture of theory and practice.

We’ll start out with building the foundations of security through an exploration of **cryptography**. From there, we’ll move to more complex, multi-faceted systems such as **web applications**, **operating systems**, and **networks**. Along the way, we’ll explore complementary topics such as authentication, physical security, social engineering, privacy, anonymity, usability, and the security of emergent systems such as blockchains and machine learning.

By learning about security through these multiple domains, you’ll concretely learn how various classes of attacks appear in a vast variety of scenarios and how they work in practice. You’ll also learn how to evaluate systems adversarially, from writing precise security analyses about subtle issues in protocols to discovering and exploiting vulnerabilities in concrete technical systems for yourself.

Through all of these activities, you’ll ultimately work to develop a specific kind of intuition—a ***“security mindset”***—that will give you the knowledge, vocabulary, and confidence to critically analyze and effectively defend the software and systems you approach as a computer scientist even after the course. - Provide an introduction to computer security
    - Overview security threats and defenses
- Help you develop a security-aware mindset:
    - Take the big picture and understand the details
- Learning by practicing
    - Consider ethical implications and tradeoffs of using, building, and testing secure systems You should have an intro-sequence’s worth of programming experience ([0160](https://cs.brown.edu/courses/info/csci0160/), [0180](https://cs.brown.edu/courses/info/csci0180/), or [0190](https://cs.brown.edu/courses/info/csci0190/)) and have a good understanding of systems programming ([0300](https://cs.brown.edu/courses/info/csci0300/), [0330](https://cs.brown.edu/courses/info/csci0330/), [1310](https://cs.brown.edu/courses/info/csci1310/), or [1330](https://cs.brown.edu/courses/info/csci1330/)). This concretely means that:

- You should be comfortable writing programs and scripts in the language of your choice (such as Python, Ruby, Bash, Go, C++, etc.), be comfortable in a Unix command-line environment (running binaries, filesystem navigation, etc.) and using SSH with the Brown CS filesystem, have a basic understanding of systems programming concepts such as memory management and networking.
- You also should have heard of the terms “race condition”, “packet”, “TCP”, “UDP”, “buffer overflows”, and “DNS”. (If you forget what these are, don’t worry—we’ll describe them again when they come up in the latter half of the course.)
- You should also be at least somewhat comfortable (and very willing) to learn new programming languages and reading code in languages and programs that you’ve never used before. (You’ll get lots of practice with this in this course!)
 
*If you don’t meet the official prerequisites* but still want to take the course, please feel free to ask the instructors–we are happy to discuss your individual situation to determine if the course is right for you!

Your willingness to challenge yourself is perhaps the most important prerequsite for the course. Security can be frustrating at times, but the rewards are great. In exchange for engaging with some difficult intellectual challenges, you’ll have the opportunity to gain concrete insights about systems and security and become a better computer scientist along the way!
