Abstract
The paper deals with the meaning, essence and rationality of the legal regulation of crimes against computer systems in the Czech Criminal Code, which contains a total of three crimes, two of which are intentional and one is negligent. The text also points out the basic interpretative problems that have not yet been satisfactorily resolved. The legal regulation of so-called computer crimes is a proof of how the Czech legislator implements international and European obligations. It also characterizes to a large extent the current
Czech criminal legislation.
