Course Description

This course aims help students to learn the principles of computer security and understand how various security attacks and countermeasures work. It provides hands-on experience in playing with security software and network systems in a live laboratory environment, with the purpose of understating real-world threats. The course will take both offensive and defense methods to help student explore security tools and attacks in practice. It will focus on attacks (e.g., buffer overflow, dirty COW, format-string, XSS, and return oriented programming), hacking fundamentals (e.g., scanning and reconnaissance), defenses (e.g., intrusion detection systems and firewalls). Students are expected to finish intensive lab assignments that use real-world malware, exploits, and defenses

Course Objectives

This course offers an in depth experience of real-world threats and defenses. Upon successful completion of this class, the student will gain experience in:

Understanding on real-world security vulnerabilities, exploits and defenses
Having hands-on labs in network and system security experiments
Learning knowledge of practical security problems and their solutions

Prerequisites

Familiar with Unix/Linux systems; or permission of the instructor.

Recommended Book
