This course provides learners with a baseline understanding of common cyber security threats, vulnerabilities, and risks. An overview of how basic cyber attacks are constructed and applied to real systems is also included. Examples include simple Unix kernel hacks, Internet worms, and Trojan horses in software utilities. Network attacks such as distributed denial of service (DDOS) and botnet- attacks are also described and illustrated using real examples from the past couple of decades. Familiar analytic models are outlined such as the confidentiality/integrity/availability (CIA) security threat framework, and examples are used to illustrate how these different types of threats can degrade real assets. The course also includes an introduction to basic cyber security risk analysis, with an overview of how threat-asset matrices can be used to prioritize risk decisions. Threats, vulnerabilities, and attacks are examined and mapped in the context of system security engineering methodologies.

Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption.

What makes WiFi faster at home than at a coffee shop? How does Google order its search results from the trillions of webpages on the Internet? Why does Verizon charge $15 for every GB of data we use? Is it really true that we are connected in six social steps or less? These are just a few of the many intriguing questions we can ask about the social and technical networks that form integral parts of our daily lives. This course is about exploring the answers, using a language that anyone can understand. We will focus on fundamental principles like “sharing is hard”, “crowds are wise”, and “network of networks” that have guided the design and sustainability of today’s networks, and summarize the theories behind everything from the social connections we make on platforms like Facebook to the technology upon which these websites run. Unlike other networking courses, the mathematics included here are no more complicated than adding and multiplying numbers. While mathematical details are necessary to fully specify the algorithms and systems we investigate, they are not required to understand the main ideas. We use illustrations, analogies, and anecdotes about networks as pedagogical tools in lieu of detailed equations. All the features of this course are available for free. It does not offer a certificate upon completion.

This course is the definitive introduction to blockchain for both the developer and non-developer audience. Beyond the technology, this course will introduce you to some of the philosophy behind decentralization and why there is so much excitement around it. During the first three modules, you'll be introduced to blockchain and the technology behind it. In module four, we'll go beyond bitcoin and delve deeper into a next-generation blockchain called Ethereum to introduce you to what modern blockchains can do. The use cases featured in the final module are drawn from among the businesses in ConsenSys' startup portfolio. We believe we're uniquely positioned to present you with a valuable behind-the-scenes look at the people and companies working in this space to help give you a better understanding of the business side of blockchain. Together, we'll examine businesses use cases, hear from industry leaders, and give you the opportunity to develop and analyze a use case yourself. With this course, not only will you be the one who is able to explain blockchain to your colleagues, you'll be well on your way to making educated business decisions with your new, foundational understanding of the technology.

By nature, cyber conflicts are an international issue that span across nation-state borders. By the end of the course, you will be able to apply the knowledge gained for analysis and management of international cyber incidents and conflicts including for activities such as development of policy related to cybercrime and cyberwarfare. Management of cyber incidents and conflicts requires an interdisciplinary perspective including an understanding of: 1) characteristics of the cyber threats and conflicts themselves, 2) international efforts to reduce and improve cyber security, and 3) psychological and sociopolitical factors. The course is designed to reach an international audience and will encourage discussion on relevant current events among participants to enrich the experience with various personal and cultural perspectives on cutting-edge issues. In addition, assignments and other assessments will supplement video lectures and selected readings to ensure application of the material. After taking this course you will be able to: • Identify different types of actors involved in cyber threats (individuals, organizations & nation-states) • Distinguish between different types of threats and issues in cyber security including, data theft, political espionage, critical infrastructure protection, and propaganda • Detail the basic characteristics of the Internet infrastructure and international efforts to address Internet governance • List several international efforts to address cyber crime and espionage • Evaluate how principals that govern international conflicts might be applied in context of cyber security • Apply different psychological theories of human motivation and cooperation and communication and political theories in analysis of different international issues related to cyber security including censorship, media operations and role of social technologies. Grading: Your grade is assessed based on discussion posts and quizzes. Individual taking this course for credit (i.e. students at the University at Albany y will be required to engage in additional activities communicated to them directly). Recommended Background: No background knowledge or skills are necessary, but an understanding and familiarity of cyber security, Internet infrastructure and international law would be advantageous for anyone who participates in the course.
