Leveraging operational technology and the Internet of things to attack smart buildings

In recent years, the buildings where we spend most part of our life are rapidly evolving. They are becoming fully automated environments where energy consumption, access control, heating and many other subsystems are all integrated within a single system commonly referred to as smart building (SB). To support the growing complexity of building operations, building automation systems (BAS) powering SBs are integrating consumer range Internet of things (IoT) devices such as IP cameras alongside with operational technology (OT) controllers and actuators. However, these changes pose important cybersecurity concerns since the attack surface is larger, attack vectors are increasing and attacks can potentially harm building occupants. In this paper, we analyze the threat landscape of BASs by focusing on subsystems which are strongly affected by the advent of IoT devices such as video surveillance systems and smart lightining. We demonstrate how BAS operation can be disrupted by simple attacks to widely used network protocols. Furthermore, using both known and 0-day vulnerabilities reported in the paper and previously disclosed, we present the first (at our knowledge) BAS-specific malware which is able to persist within the BAS network by leveraging both OT and IoT devices connected to the BAS. Our research highlights how BAS networks can be considered as critical as industrial control systems and security concerns in BASs deserve more attention from both industrial and scientific communities. Even within a simulated environment, our proof-of-concept attacks were carried out with relative ease and a limited amount of budget and resources. Therefore, we believe that well-funded attack groups will increasingly shift their focus towards BASs with the potential of impacting the live of thousands of people.

     

Internet of things assisted condition-based support for smart manufacturing industry using learning technique

Nowadays, countless industrial IIoT contraptions and sensors are conveyed a sharp plant to gather tremendous information regarding system conditions and a computerized bodily framework for handling industrial plant's mist point of convergence by using keen assembling projects. By then, the system utilizes an array of condition-based support model (CBM) procedures to predict when devices begin to unusually work and to keep them up or supplant their fragments ahead of time to avoid assembling colossal investigator items in smart manufacturing industries. CBM experiences problems of floating ideas (ie, conveying examples of deficiencies can change extra time) and information of lop-sidedness (ie, information with issues represents a minority of all things considered). The condition-based support assisted learning technique by the group that coordinates the assorted variety of numerous classifiers provides an elite response to address these issues. Therefore, in this work the proposed work classifies offline three-organized CBM with floats of ideas and awkwardness data, using an improved Dynamic AdaBoost for preparing a group classifier and an enhanced linear four rates (LFR) methodology is used by the classifier of nominal and continuous (NC) with synthetic minority oversampling technique (SMOTE) method to tackle inconsistent information in recognizing concept floats in lop-sidedness information. The investigational results scheduled datasets by varying notches anomaly demonstration that the future strategy has a high degree of accuracy in the identifiable evidence of minority knowledge, which is over 96%.

A two-level authentication scheme for clone node detection in smart cities using Internet of things

Clone node attack in IoT sensor devices remains a grave security concern as it paves the way for sinkhole, wormhole, and selective forwarding attacks. In this paper, a two-level authentication scheme named Fingerprint-based Zero-Knowledge Authentication (FZKA) algorithm is proposed to improve the detection rate of clone node among the sensor devices. In the fingerprint generation phase, the base station calculates a distinct fingerprint value for each and every node in the network by gathering neighborhood information, represented in the form of superimposed s-disjunct code matrix. The calculated fingerprint is considered as a secret value and distributed to each cluster nodes for the process of authentication. The FZKA algorithm improves the cloned node detection accuracy with minimal detection time. The simulation results highlight the cloned node detection rate of the proposed scheme by a margin of 92.5% against the existing Exponential Smoothing Algorithm (ETS), Position Verification Method, and Message Verification and Passing algorithms.
