Course Description

This course focuses on the security and privacy issues in Cloud Computing systems. While the cloud computing paradigm gains more popularity, there are many unresolved issues related to confidentiality, integrity, and availability of data and computations involving a cloud. In this course, we will examine cloud computing models, look into the threat model and security issues related to data and computation outsourcing, and explore practical applications of secure cloud computing.

Since cloud computing is a very young field, we will mainly study the cutting edge research published in recent conferences.

 

Course Topics

  1. Definition of Cloud computing (NIST)
  2. Cloud computing models
  3. Secure data outsourcing
  4. Secure computation outsourcing
  5. Proof of data possession / retrievability
  6. Virtual machine security
  7. Trusted computing technology and clouds
  8. Cloud-centric regulatory compliance issues and mechanisms
  9. Business and security risk models
  10. Applications of secure cloud computing
 

Evaluation

Evaluation will be done through weekly review assignments. Each assignment will consist of writing a very brief review of a paper.

For each review, you will have to write the following:

  • summary: a short overview of the paper (no longer than a paragraph of 5-10 sentences)
  • pros: 3 or more things about the paper that you liked
  • cons: 3 or more shortcomings of the paper
  • ideas: any suggestions on how to fix the shortcomings of the paper

Assignments are due at 2.30 pm each Monday.
