According to popular movies, a hacker breaks into the FBI systems for breakfast, gets access to a government’s classified information within seconds, and can trace your chat history with just a few clicks of a button. For the most part, those scenarios stay in the movies. But how do network systems prevent these kinds of scenarios from happening?
By following this course, students will gain a basic understanding of the principles behind network security and the working of the main protocols, mechanisms, and techniques in the area of security.
The course consists of three parts:
- Internet Security Protocols,
- Internet Security Attacks and Defense,
- Web security.
In the first part, the following topics will be discussed: WEP/WPA, IPSec, SSH, TLS, and HTTPS. The second part discusses topics like scans, intrusions, DDOS attacks, and firewalls. The last part focuses on web security, including SQL-injection and X-side scripting attacks.
Teaching method
The course will be organised as a blend of frontal lectures supported by lab assignments in the form of a Massive Online Open Course (MOOC). The course will run in the third quarter. The course will offer guest lectures from industry and academic experts in the field of Internet Security.
The MOOC consists of three modules:
- Internet Security Protocols,
- Internet Security Attacks and Defence,
- Web security.
Assessment
Weekly exercise and written exam. Weekly exercises via the MOOC platform; the web hacking assignment are those from Certified Secure (https://www.certifiedsecure.com).
