Course description and aims

The first half of this course focuses on cryptographic technologies. The functions and mechanisms of cryptographic technologies such as cryptosystems and authentication scheme that are used in the Internet are explained. The latter half focuses on network security. Various attack techniques, Web security, DNS/Email security, and techniques for defense are explained.
Threat to communication networks grows every year, and a variety of security technologies are investigated to defend networks. Still, they are not defended completely. Learning the security technologies, students are expected to be able to investigate and analyze appropriately the situation.

Student learning outcomes

At the end of this course, students will be able to :
1) have an understanding of fundamental knowledge to defend networks from threat,
2) appropriately investigate and analyze the situation of networks,
3) select and use appropriate security technologies.

Keywords

Cryptosystem, authentication, digital signature, PKI, access control, malicious software, port scan, DoS attack, firewall, Anti-Virus Software

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

In the first half, mainly the lecturer introduces various techniques using slides.
The latter half includes practical training using computers.
