Computer and Network Security

Title Computer and Network Security (56515)
Quarter Autumn 2015
Instructor TBD


Course Description
If you're at all keeping up with current events in the world, you can't have missed seeing reporting on information security incidents - from small to gargantuan almost every day.  This class will give you insight into the issues involved with these security breaches - why they happen, how they are detected and how to defend technology to mitigate these risks.  Information Security is a fast-growing, fast-changing field today - job listings show how the world needs further competent professionals dedicated to this field and recent incidents also show how security education is vital for all technology professionals.

The objective of this course is to provide a basic understanding of Information Technology security - and to build an understanding of the elements that should be in place for an IT environment to achieve an adequate security level.  We will begin with a general overview of IT security and introduce a framework for addressing security needs across an enterprise.  Major security objectives and technical mechanisms for attaining these objectives will be discussed, including cryptography, authentication systems, Public Key Infrastructure, and platform and network security mechanisms.  This course will give an overview of the technical details involved in the platform and network levels of security, including hands-on usage of current tools used in the field.  We will look at common TCP/IP applications and discuss their security vulnerabilities.  The course material will be presented in a framework of understanding overall risks and how to address them.

There will be a great deal of reading in this course.  Students should have the ability to read and write in clear prose.  Students in this course will be writing an in-depth paper or a project and should have the ability to write a substantial paper.
