Networking Security

Course Description

Network Security studies the concepts and tools used to prevent and monitor unauthorized access, misuse, modification, or denial of  a computer network or network resources. In this course, students will learn the fundamentals of network security – cryptography, popular security applications and packages, as well as real world projects designed to put the students’ skills to the test. At the end of the course, the students should have through understanding of the themes and challenges of network security, the role of cryptography, the techniques for access control and intrusion detection, and skills to implementing security protocols. This course is suitable for students who wish to become network security specialists, as well as those who are interested in cryptography.
