This course provides a broad-spectrum introduction to the fundamental principles of network security and privacy enhancing technologies. The structure of this course follows the OSI/ISO architecture of network security, more specifically that of the TCP/IP model. The main learning objectives of the course are as follows:

• To provide a deep understanding of network security and its changing nature.
• To explain and demonstrate how network security is perceived and carried out.
• To analyze the various categories of threats, vulnerabilities, countermeasures and repelling strategies
• To conceptualize the challenges of network security.
• To familiarize the students with the basic terminology and technologies of data privacy in networking environment and examine typical anonymity networks (Tor, I2P), applications, and use-cases.

The aim of the projects is to provide students with the knowledge and skills necessary to design and support network security and privacy. The aforementioned objectives are met through course lectures, paper readings, and laboratory exercises.
