SCADA systems have historically been isolated from other computing resources. However, the use of TCP/IP as a carrier protocol and the trend to interconnect SCADA systems with enterprise networks introduce serious security threats. This paper describes two strategies for securing SCADA networks, both of which have been implemented in a laboratory-scale(More)
This paper describes the design and implementation of a passive scanner for Modbus networks. The tool integrates packet parsing and passive scanning functionality to interpret Modbus transactions and provide accurate network representations. In particular, the scanner monitors Modbus messages to maintain and update state table entries associated with field(More)
Hand pose recognition is a hard problem due to the inherent structural complexity of the hand that can show a great variety of dynamic configurations and self occlusions. This work presents a hand pose recognition pipeline that takes advantage of RGB-Depth data stream, including hand detection and segmen-tation, hand point cloud description using the novel(More)
Non-supervised multiple-agent tracking is a complex task which demands a structured framework in order to accomplish it. Therefore, this proposal presents a system which is modular and hierarchically organised. It consists in several levels, working in cascade, which are defined according to the different functionalities to be performed. The goal of this(More)
This paper focuses the transformation process between quantitative data obtained from pattern analisis procedures, and qualitative statements which are suitable for semantic reasoning. Within a human motion modeling framework, we address how numerical information, which is embedded in a predefined state vector of an observed agent, instantiates logic(More)
