The IT Security major specialization introduces the main security problems of IT systems and the approaches, methods, and tools used to solve those problems. We put the emphasis on practical applications, while students also get familiar with the security analysis techniques and design principles through the analysis of different security solutions. Those who complete the IT Security major specialization are able to identify security problems in practical IT systems, analyze and understand such problems, and design and develop appropriate security solutions. The students also learn when and how to apply cryptography to practical security problems.
The IT Security major specialization consists of four courses (Software Security (VIHIMA21), Computer and Network Security (VIHIMA23), Cryptographic Protocols (VIHIMB08), Security of Machine Learning (VIHIMB09)) and two lab exercises (Software Security Laboratory (VIHIMA22), Computer and Network Security Laboratory (VIHIMB07)). We also supervise student semester and diploma projects.
This BProf course gives an overview of the different areas of IT security with the aim of increasing the security awareness of computer science students and shaping their attitude towards designing and using secure computing systems. The course also gives an introduction to source coding and channel coding.
Topics: IT security in practice; user authentication and access control basics; basic memory corruption attacks; secure programing methods and security testing of software; malware and malware detection; web security; network security, firewalls, and IDS systems; introduction to cryptography; cryptographic protocols; lossless and lossy compression; channel coding.
This course gives an introduction into the security problems of computer networks, and it gives an overview of the possible solutions to those problems. It also covers issues related to secure operation of networks in practice, including modern tools and techniques used to ensure security. Students get theoretical knowledge and practical skills that form the basis of secure network operations.
Topics: authentication and authorization; firewalls; intrusion detection/prevention systems, SIEMs; virtual private networks; logging; network infrastructure security (e.g., DNSSEC); botnets; web security; spam filtering; detection of DoS attacks; routing security; network penetration testing
This laboratory extends and deepens the knowledge and skills obtained in the Network Security in Practise and Computer Security in Practise courses by solving practical, hands-on exercises in real, or close-to-real environments.
Topics: VLANs; routing; DHCP and NAT; firewalls; virtual private networks; logging; ethical hacking
We offer semester and diploma projects that are related to the research activities in the lab, or proposed by our industrial partners, therefore, they provide the opportunity for the students to join our research and development projects, or collaborate with our industrial partners.
If you are a student interested in any of our current project proposals, please, get in touch with the given contact person of the project before officially applying. The contact person will let you know the necessary steps for taking the project officially.
We pay special attention to attract and work with students interested in IT security. To discover talented students, we organize the annual CrySyS Security Challenge, which is a hacking contest with exciting problems to solve. For students, the Sec Challenge provides a platform for "learning by doing"; for us, it is a vehicle to discover students talented in hacking. We also identify talents in the classroom and by supervising semester projects.
Those who prove to be strongly interested in IT security and committed to hard working are invited to join the CrySyS Student Core, which is a community-of-practice consisting of talented students. Core members meet once a week to expand their knowledge by discussing specific topics in system and network security, to prepare for CTF competitions, to socialize, and to have fun by spending time with other geeks of similar interest.
The current CTF team of the Student Core is called c0r3dump, which is a team of fast improving young hackers who love to spend their week-ends with participating at international CTF games.
To help students bootstrapping their IT security activity, preparing for the Sec Challenge, and ultimately to get invited to the Student Core, we organize an IT Security Bootcamp. Interested in joining and becoming part of a live community? Contact András Gazdag or Levente Buttyán.
Avatao is an online e-learning platform offering IT security challenges for everyone interested in improving their skills in computer security, web security, applied cryptography, and many more sub-domains of IT security. The development of the platform was started in the CrySyS Lab before it was spun off into a standalone company. However, we continue to use the Avatao platform in our teaching as the infrastructure for the CrySyS Security Challenge, as well as for course homeworks and lab exercises. If you are interested in avatao, please contact Gabor Pek.
