Abstract
The paper examines intelligent sensor and sensor system development according to the Common Criteria methodology, which is the basic security assurance methodology for IT products and systems. The paper presents how the development process can be supported by software tools, design patterns and knowledge engineering. The automation of this process brings cost-, quality-, and time-related advantages, because the most difficult and most laborious activities are software-supported and the design reusability is growing. The paper includes a short introduction to the Common Criteria methodology and its sensor-related applications. In the experimental section the computer-supported and patterns-based IT security development process is presented using the example of an intelligent methane detection sensor. This process is supported by an ontology-based tool for security modeling and analyses. The verified and justified models are transferred straight to the security target specification representing security requirements for the IT product. The novelty of the paper is to provide a patterns-based and computer-aided methodology for the sensors development with a view to achieving their IT security assurance. The paper summarizes the validation experiment focused on this methodology adapted for the sensors system development, and presents directions of future research.

Summary
The paper is focused on the security aspects of intelligent sensors. Intelligent sensors include sensor-, processing-, communicating facilities, and sometimes actuators. They can work autonomously or can be connected forming complex structures like sensor networks or systems. To review the topic of how to distinguish intelligent sensors from smart ones [1], in this paper the author focuses on sensors which have IT product attributes, i.e., the ability to process, store and transfer information. For these specific IT products information security is the key issue
