“…The IPFIXcol with an effective storage data format can be used for monitoring high-speed networks. By changing the storage data format or an internal processing plugin to support specific information fields, the IPFIXcol can be effectively used for monitoring research and non-standard environments such as building management or SCADA networks [9].…”

Abstract. Network monitoring has became a significant part of network management. Each environment and type of network have their specific, different needs. To allow network traffic monitoring in various environments, a necessity of flexible approach thus grows. The current generation of flow collectors provides only a limited flexibility, mainly due to limits of their data storage formats. Moreover, it is quite a challenging task to compare particular storage formats and their suitability for the specific environment and usage. In this paper we present IPFIXcol -a flow collector framework designed for easy data storage formats changing. This way, we plan to evaluate performance and suitability of various data storage formats for specific tasks. Results can be used to build the most appropriate data storage for the specific production environments.

“…Traffic flow measurement has been known in IP networks for quite some time, but observing the traffic flow in BACnet networks has been done only recently [9]. The methods were later improved in [13] to include entropy-based analysis of the traffic flow.…”

Building automation systems (BAS) are interlinked networks of hardware and software, which monitor and control events in the buildings. One of the data communication protocols used in BAS is Building Automation and Control networking protocol (BACnet) which is an internationally adopted ISO standard for the communication between BAS devices. Although BAS focus on providing safety for inhabitants, decreasing the energy consumption of buildings and reducing their operational cost, their security suffers due to the inherent complexity of the modern day systems. The issues such as monitoring of BAS effectively present a significant challenge, i.e., BAS operators generally possess only partial situation awareness. Especially in large and inter-connected buildings, the operators face the challenge of spotting meaningful incidents within large amounts of simultaneously occurring events, causing the anomalies in the BAS network to go unobserved. In this paper, we present the techniques to analyze and visualize the data for several events from BAS devices in a way that determines the potential importance of such unusual events and helps with the building-security decision making. We implemented these techniques as a mobile (Android) based application for displaying application data and as tools to analyze the communication flows using directed graphs

“…An IP traffic flow-based network monitoring tool was extended by a BACnet stack for the analysis of the BACnet traffic , see [2]. A monitoring device (probe) acts as a passive listener on central nodes of the BMS network and monitors most of the network traffic occurring in the network by inspection of Ethernet frames.…”

Building construction has gone through substantial change with the emerging spread of ICT during last decades. In the field of construction industry, the term intelligent buildings describes facilities equipped with devices and systems that can be remotely controlled and programmed and that are able to communicate and collaborate in order to ensure convenient building environment and effective operation. However, installing devices with such capabilities is only one part of the task of effective facility management and risk management. Facility managers have to be provided with tools that allow them to inspect and analyze gathered building operational data and make decisions to improve building performance. Decision support tools for facility managers usually lack deep integration with building systems. This article aims on technical aspects of providing data from intelligent buildings to the responsible personnel in order to help them to operate the building effectively with emphasis on its energy consumption and risk management.
