Digital Transformation and Cybersecurity of Critical Infrastructures

compactifications and representations of transformation semigroups

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

Cybersecurity and Critical Infrastructure Protection

Cybersecurity entails the safeguarding of computer networks and the information they contain from penetration and from malicious damage or disruption. Since the use of computer networks has become a major element in governmental and business activities, tampering with these networks can have serious consequences for agencies, firms and individuals. The question is to what degree these individua...

Analysis of Critical Infrastructures

Developing an awareness of the challenges entailed in the protection of Critical Infrastructures is an important first step. Before one can take effective measures to improve the protection of Critical Infrastructures, it is necessary to understand how these function and to identify and analyse the critical processes within the Critical Infrastructures. The ACIS methodology described in this pa...
