Network Security

The course will cover mechanisms, protocols, algorithms, and architectures to provide secure Internet communication over wired and wireless networks. First, basic mechanisms and building blocks required for various security mechanisms, e.g., encryption, hashing, authentication codes, and digital signatures will be introduced. Security architectures relying on such building blocks such as Kerberos and Public Key Infrastructures will be discussed. In the Internet, security mechanisms can be found on various protocol layers. This includes Internet Protocol Security (IPSec), Transport Layer Security (TLS) and application level security, e.g., to secure Email exchange as well as access to web and cloud resources. Moreover, the Domain Name System must be secured (DNSsec). With the increasing importance of mobile and wireless networks, special attention must be given to such networks as well the Internet of Things (IoT).

Learning Outcomes

On successful completion of the course, the students will be able to

  • identify risks, possible attacks, and security requirements in Internet-based networks;
  • understand, compare, and evaluate algorithms, mechanisms, and architectures for achieving security in wired and wireless networks;
  • understand, compare, and evaluate protocols for achieving security in applications interconnecting users and end systems via the Internet;
  • understand and evaluate security protocols used for wireless networks such as WiFi, cellular networks (2G, 3G, 4G, 5G), and the Internet of Things.
