The information and control system of smart building is considered as a set of subsystems including building automation system (BAS). BAS security and availability during its life cycle are assessed using the technique Attack Tree Analysis (ATA), and Failure Modes and Effects Analysis (FMECA). The FMECA is applied at the initial stage of analysis to assess criticality of BAS hardware/software failures and failed connections between components on the different levels of system design. Modification of FMECA is IMECA allowing to analyze modes and effects of attacks/intrusions. The ATA is applied to investigate any intrusions into the BAS by analyzing system probability of a failure caused by faults and vulnerabilities during operation time. The ATA is applied for different BAS subsystems and results of analysis are combined.
