Internet security has become part of everyday life where security problems impact practical aspects of our lives. Even though there is a considerable corpus of knowledge about tools and techniques to protect systems, information about what are the actual vulnerabilities and how they are exploited is not generally available. This situation hampers the effectiveness of security research and practice. Understanding the details of attacks is a prerequisite for the design and implementation of secure systems.

This course deals with common programming, configuration, and design mistakes and ways to detect and avoid them. Examples are used to highlight general error classes, such as stack and heap overflows. Possible protection and detection techniques are examined. The course includes a number of practical lab assignments where participants are required to apply their knowledge as well as a discussion of the current research in the field. Students will learn how the security of systems can be violated, and how such attacks can be detected and prevented.

The course aims to make the students "security aware", and gain an in-depth understanding about security issues.

Some Topics

Operating system security and vulnerabilities
- (UNIX, Windows, stack and heap overflows)
Windows Security
Memory corruption
- (Buffer overflows, Heap overflows, Format string issues, etc.))

Language security
Web security


Significant Programming experience

Knowledge of C/C++ useful
Basic SQL knowledge
Basic web programming knowledge
