What is the purpose of this course?

This course will cover the fundamentals of security, security protocols, and their applications in real-world. The topics covered in this course include applied cryptography, authentication, passwords, practical security, social aspects of security, SSL/TLS, email security, PKI, and IPSec. Furthermore, this course will strengthen the security knowledge of the students and guide them in the right direction for their upcoming research projects and advanced courses. The course is divided into two parts. The first part will cover the theory and hands-on practice of the concepts taught at class. And the second part of the course will focus on the course projects. The student will work on a security project by using the concepts taught in the class.
