Measures for critical infrastructure protection

Methematical models and methods are applied across different scientific fields. Including the issues of critical infrastructure protection (CIP) which has come forward in the interest of EU in the last decade. In order to understand the broader connections and the present state of CIP, the article speaks of the contemporary process of marking and identification ECI and entities which are (or should be) included in this process - specifically in Czech Republic. The main aim of the article is to introduce the measures for the critical infrastructure protection. These measures often use a mathematical apparatus, namely in the field of determining threats, evaluation of risks and forming of exceptional events etc. The purpose of the article is not only to list the mathematical models, tools or methods used but to introduce the issues of critical infrastructure protection and open areas, in which these models, tools and methods can be used
