Course list

In this course, you will examine security for computers and networked information systems. The focus is abstractions, principles, and defenses for implementing military and commercial-grade secure systems. Through this lens, you will explore security and survivability for computers and communications networks as well as policy issues such as the national debates on cryptography policy and the meaning of privacy. That journey will be informed by a survey of technical means for implementing the various properties that comprise "trustworthiness" in a computing system, including mechanisms for authorization and authentication along with cryptographic protocols.

Protocols for authenticating machines play an important role in systems security, and this course will focus on various aspects of this challenge. Using case studies of protocols that work and that have failed will help you to acquire the skill — and the skepticism — necessary to analyze and deploy authentication protocols successfully. In this course, you will investigate shared key and public key cryptography along with the trade-offs associated with these different types of keys. You will also examine some of the standard cryptographic building blocks and their use.

If an attacker can masquerade as an authorized user of a system, then many other defenses become irrelevant. This course addresses how a computing system can authenticate a human user, discussing implementations of mechanisms as well as their privacy implications. You will explore the protocols of passwords, biometrics, and tokens, along with their combination as multifactor authentication.

Access control mechanisms ensure that a user is able to read and/or update only certain objects. With discretionary access control, it is the creator of an object who decides which other users should have access. A broad set of mechanisms have been developed to enforce discretionary access control in a computing system. This course will survey the two approaches widely used in these mechanisms: access control lists and capabilities. Through the use of case studies, you will review the pragmatics of implementations in processor hardware, operating systems, and programming languages.

It is recommended to only take this course if you have completed “Systems Security,” “Authenticating Machines,” and “Authenticating Humans,” or have equivalent experience.

Symposium sessions feature two days of live, highly interactive virtual Zoom sessions that will explore today's most pressing topics. The Leadership Symposium offers you a unique opportunity to engage in real-time conversations with peers and experts from the Cornell community and beyond. Using the context of your own experiences, you will take part in reflections and small-group discussions to build on the skills and knowledge you have gained from your courses.

Join us for the next Symposium in which we'll discuss the ways that leaders across industries have continued engaging their teams over the past two years while pivoting in strategic ways. You will support your coursework by applying your knowledge and experiences to relevant topics for leaders. Throughout this Symposium, you will examine different areas of leadership, including the psychology of leadership; women in leadership; and leading in a volatile, uncertain, complex, and ambiguous world. By participating in relevant and engaging discussions, you will discover a variety of perspectives and build connections with your fellow participants from various industries.

All sessions are held on Zoom.

Future dates are subject to change. You may participate in as many sessions as you wish. Attending Symposium sessions is not required to successfully complete any certificate program. Once enrolled in your courses, you will receive information about upcoming events. Accessibility accommodations will be available upon request. For future reference, download our Symposium course flyer.

Have you ever known a very intelligent person who made a very bad decision? If so, you know that having a high IQ does not guarantee that you automatically make critically thoughtful decisions. Critically thoughtful problem-solving is a discipline and a skill—one that allows you to make decisions that are the product of careful thought, and the results of those decisions help your team and organization thrive.

In this course you will practice a disciplined, systematic approach to problem solving that helps ensure that your analysis of a problem is comprehensive, is based on quality, credible evidence, and takes full and fair account of the most probable counterarguments and risks. The result of this technique is a thoroughly defensible assessment of what the problem is, what is causing it, and the most effective plan of action to address it. Finally, you will identify and frame a problem by assessing its context and develop a well-reasoned and implementable solution that addresses the underlying causes.

When trying to persuade someone, the tendency is to begin in advocacy mode—for example: “Here's something I want you to agree to.” Most people do not react positively to the feeling of being sold something. The usual reaction is to literally or figuratively start backing up. To make a convincing case, it is more effective to engage with the decision maker as a partner in problem-solving. This makes your counterpart feel less like someone is trying to get them to buy something and more like you are working together to bring about an outcome that is desirable to both parties. Begin by asking yourself: “What is the problem you and the decision maker are solving together?”

By the end of this course, you will have learned how to deeply analyze a problem, possible solutions, and the associated risks as well as the most persuasive and efficient ways of presenting your proposal.

Your work in a technical field likely means that you periodically interact with colleagues, customers, suppliers, and other stakeholders who live in a different part of the world, speak a primary language different from your own, or have expertise in a different or non-technical field.

As a technical expert, your ability to anticipate the needs of audiences from diverse backgrounds and communicate effectively with them is essential.

In this course, you will have an opportunity to explore how you can prepare to meet the needs of audiences with differing backgrounds, primary languages, and levels of expertise, and even varying degrees of receptivity to your message. You will examine principles of persuasion and consider how and when to apply them both effectively and ethically. As part of your studies, you will also review pertinent selections from Dr. Traci Nathans-Kelly's book “Slide Rules,” and you will look at how you can prepare for the unexpected in your talks and maintain your composure when disruptions occur.

By the end of this course, you will have gained techniques and insights that you can apply as you prepare and develop presentations for a wide range of audiences with varying needs and interests.

You will be required to purchase Traci Nathans-Kelly's book “Slide Rules” to complete your coursework.

You are required to have completed the following course or have equivalent experience before taking this course:

  • Redesigning Slides for Impact
  • Engaging Presentation Techniques
  • Designing Slides for Live and Legacy Use

Effective communication skills are the hallmark of a professional no matter what the profession. In this course, you will begin to parse the ways in which you present yourself to others as a technical expert. In any presentation or talk that you give, whether face to face or online, you want to project expertise, confidence, and professionalism. The idea of professionalism, however, can vary. Everyone expects professionalism, but the definition and perception of professionalism differs greatly among individuals, organizations, nations, and cultures.

In this course, you will delve into the concept of professionalism in presentations and explore how it varies depending upon the context, the participants, and their expectations.

You will study effective practices for designing, developing, and delivering professional-grade online meetings and team presentations. Additionally, you will have an opportunity to examine the importance of your body language, eye contact, and voice in projecting confidence in your talks, regardless of the setting or delivery medium. You will then record a talk and take an inventory of your expert presence in the video. You will also investigate the nuances and complexities of developing and delivering team presentations. In the final part of the course, you will complete the process of preparing to deliver a professional-level team talk.

You will be required to purchase Traci Nathans-Kelly's book “Slide Rules” to complete your coursework.
