Today’s society relies on cyber space for almost everything, including banking, transport and logistics, air travel, energy, telecommunications, flood defence, healthcare, email, social networks, and even warfare. The consequences of cyber security failures could be disastrous and the demand for cybersecurity specialists is therefore high and rising.

Cyber security is all about the assessment of cyber risks and the design and implementation of counter-measures. Good cyber security measures start with the prevention of attacks. Think, for example, of encryption, firewalls and awareness campaigns. As ‘100% security’ is unaffordable, the next stage of cyber security is the timely detection of attacks. Think of using intrusion detection tools and data analytics. The third stage is the recovery from attacks, for example, using incident response methods and backups. Cyber risk management is the process used to make sure that the right resources are allocated. It is all about balancing these three categories of cyber security measures in order to reach states of acceptable risk levels in various cyber domains.

Cyber security is a multidisciplinary field with computer science at its core. It involves cryptography, formal methods, secure software engineering, and machine learning, among other things. It also touches on a broad range of supporting disciplines, such as law, economics, criminology, management, and psychology.


The 4TU Cyber Security Master’s specialization offered by the University of Twente and Delft University of Technology gives students taking a Master’s in Computer Science the opportunity to become highly sought after cyber security specialists.

As a student of the 4TU Cyber Security Master’s specialization, you can enrol in the Computer Science Master’s at the University of Twente or at Delft University of Technology. Most courses are taught via tele-lecturing, so that travel between the universities is minimal. The programme takes two years and consists of 120 EC courses and project work. You can start in September and in February.

Please note that this is not a joint degree. After completing the 4TU Cyber Security Master's specialization you will receive a diploma from the University of Twente – if you complete the programme here, that is – with a certificate in Cyber Security.


As a cyber security graduate, you will not have any problems finding a job. You can work for a variety of organizations, including the police, ministries, the IT security industry, auditors, research organizations and universities, both in the Netherlands and abroad.

Examples of jobs include: 

  • Computer and network security specialist
  • Digital expert police
  • Entrepreneur and security consultant
  • Ethical hacker
  • Information security advisor
  • PhD student
  • Security analyst
  • Teacher
