Skip About this course

This is the 1st course in the intermediate, undergraduate-level offering that makes up the larger Cybersecurity Fundamentals MicroBachelors Program. We recommend taking them in order, unless you have a background in these areas already and feel comfortable skipping ahead.

  1. Information Security - Introduction to Information Security
  2. Information Security - Authentication and Access Control
  3. Information Security - Advanced Topics
  4. Network Security - Introduction to Network Security
  5. Network Security - Protocols
  6. Network Security - Advanced Topics
  7. Penetration Testing - Discovering Vulnerabilities
  8. Penetration Testing - Exploitation
  9. Penetration Testing - Post Exploitation

These topics build upon the learnings that are taught in the introductory-level Computer Science Fundamentals MicroBachelors program, offered by the same instructor.

This is a self-paced course that provides an introduction to information security and cybersecurity. Among the topics covered are Security Design Principles, Threat Modeling, and Security Policy. Students gain a broad overview of Information Security and Privacy (ISP) through high-level ISP concepts. We discuss both traditional design principles and principles that were developed to design secure systems. We'll talk about several examples of insecure design and techniques to improve the design. We take an in-depth dive into creating models to measure potential threats. We also talk about risk and ways of managing and measuring the risk to assets. We conclude by taking an in-depth look at different security policy models, including the Bell-La Padula (BLP) Model, the Biba Integrity Model, Lipner's Model, and Clark-Wilson Integrity Model. Next, we consider the practical aspects of the implementation of the policy models.

Unfortunately, learners residing in one or more of the following countries or regions will not be able to register for this course: Iran, Cuba and the Crimea region of Ukraine. While edX has sought licenses from the U.S. Office of Foreign Assets Control (OFAC) to offer our courses to learners in these countries and regions, the licenses we have received are not broad enough to allow us to offer this course in all locations. edX truly regrets that U.S. sanctions prevent us from offering all of our courses to everyone, no matter where they live.
