Wireless communication has become very popular in industry, business, commerce, and in everyday life. Wireless technology spans from user applications, such as personal area networks, ambient intelligence, and wireless local area networks, to real-time application. The given paper shows the analysis of wireless network security and availability, and helps to develop safe and effective system usable for future design. Smart building automation system is one of work areas of embedded wireless network in system design. Technique of criticality matrix based security assessment is described and illustrated for smart BAS.

Building automation system is represented by a programmed, computerized, intelligent network that units electronic devices for monitoring and controlling all building services systems in a facility. BAS is needed in order to create an intelligent, effective building as well as to reduce energy and maintenance costs. Usually building automation systems have a primary and secondary bus containing programmable logic controllers, input/outputs and an operator interface. Building automation system architecture divided as three main levels (management level, communication level, automation level). The analysis of the communication level give an image about system availability and security under threat and cyber attacks.Building automation system is represented by a programmed, computerized, intelligent network that units electronic devices for monitoring and controlling all building services systems in a facility.

The given paper helps to understand threats and attacks on wireless network, and to manage network in different application fields that require high security. Building automation system (BAS) is one of the fields of wireless network application which requires high level of security. The paper analyzes communication system for BAS, and helps to understand the threats which can affect a system by describing and investigating vulnerability of two important components in BAS-communication system. The goal of this paper is to show vulnerability of wireless network and to apply this analysis in BAS.
