This chapter aims to develop an understanding of sensor networks and the security threats posed to them, owing to the inherently insecure wireless nature. It also highlights the current security issues associated with the exchange of information and presents respective countermeasures that can be used to secure the network of malevolent behavior. It builds the reader's understanding of security threats by presenting an idealistic security mechanism and comparing it to currently practiced security mechanisms. Doing so, it identifies the security flaws in each mechanism, henceforth, enumerating a list of well-known security attacks that are connected to the respective security flaws. To provide a better understanding of security threats, the security attacks, in general, are discussed in the perspective of a network administrator, and an adversary. Their impact is also considered from the side of a network administrator and its respective benefits to the adversary. The chapter is later concluded along with future directives and an insight on requirements of forthcoming technologies.

Underwater Wireless Sensor Networks (UWSN) have gained more attention from researchers in recent years due to their advancement in marine monitoring, deployment of various applications, and ocean surveillance. The UWSN is an attractive field for both researchers and the industrial side. Due to the harsh underwater environment, own capabilities, and open acoustic channel, it is also vulnerable to malicious attacks and threats. Attackers can easily take advantage of these characteristics to steal the data between the source and destination. Many review articles are addressed some of the security attacks and taxonomy of the Underwater Wireless Sensor Networks. In this study, we have briefly addressed the taxonomy of the UWSNs from the most recent research articles related to the well-known research databases. This paper also discussed the security threats on each layer of the Underwater Wireless sensor networks. This study will help the researchers design the routing protocols to cover the known security threats and help industries manufacture the devices to observe these threats and security issues.

The Relationship

Event-based system (EBS) is prevalent in various systems including mobile cyber physical systems (MCPSs), Internet of Things (IoT) applications, mobile applications, and web applications, because of its particular communication model that uses implicit invocation and concurrency between components. However, an EBS’s non-determinism in event processing can introduce inherent security vulnerabilities into the system. Multiple types of attacks can incapacitate and damage a target EBS by exploiting this event-based communication model. To minimize the risk of security threats in EBSs, security efforts are required by determining the types of security flaws in the system, the relationship between the flaws, and feasible techniques for dealing with each flaw. However, existing security flaw taxonomies do not appropriately reflect the security issues that originate from an EBS’s characteristics. In this paper, we introduce a new taxonomy that defines and classifies the particular types of inherent security flaws in an EBS, which can serve as a basis for resolving its specific security problems. We also correlate our taxonomy with security attacks that can exploit each flaw and identify existing solutions that can be applied to preventing such attacks. We demonstrate that our taxonomy handles particular aspects of EBSs not covered by existing taxonomies.

With the advances in technology, there has been an increasing interest from researchers and industrial institutions in the use of underwater wireless sensor networks (UWSNs). Constrained by the open acoustic channel, harsh underwater environment, and their own particularities, UWSNs are vulnerable to a wide class of security threats and malicious attacks. However, most existing research into UWSNs has not taken security into consideration. Moreover, the existing relatively mature security mechanisms for WSNs cannot be directly utilized in UWSNs. For these reasons, this article aims to present a comprehensive overview of the particularities, constraints, attacks, challenges and current security mechanisms of UWSNs. In addition, challenging, open and hot research topics are outlined.

Abstract. Smart environments provide many benefits to the users including comfort, convenience, energy efficiency, safety, automation, and service quality. The Internet of Things (IoT) has developed to become one of the widely used technologies in smart environments. Many security attacks and threats are generated by security flaws in IoT-based systems and devices, which may affect smart environments applications. As a result, security is one of the most important issues in any smart area or environment based on the IoT model. This paper presents an overview of smart environments based on IoT technology and highlights the main security issues and countermeasures in the four layers of smart environment IoT architecture. It also reviews some of the current solutions that ensure the security of information in smart environments applications.

A sensor network consists of a large number of sensor nodes, which are spread over a geographical area. Sensor networks have found their way into many applications, from military domains to traffic or environmental monitoring, and as sensor networks reach toward wide spread deployment, security becomes a major concern. In this regard, one needs to be sure about the confidentiality, authenticity and tamper-proof of data. The research thus far has focused on how to deploy sensor networks so that they can work efficiently; however, the focus of this paper is on sensor networks’ security issues. In this paper, the authors propose a formal model to design and analyze the secure sensor network system. The model is based on an augmented Petri net formalism called Extended Elementary Object System. This proposed secure sensor network model has a multi-layered structure consisting of sink node layer, sensor node layer and security mechanism layer. At the security mechanism layer, a synchronous firing mechanism is utilized as a security measure to detect malicious node attacks to sensor data and information flow. In addition, the model applies SNEP protocol for authentication and confidentiality of sensor data.

Underwater Sensor Network (UWSN) is a powerful technique for aquatic applications. Although the international researches on this topic are quite prosperous, it is still in its early stage of development. UWSN is vulnerable to various kinds of attacks because it is usually deployed in hostile environments. This paper systematically summarizes and analyzes the existing security attacks and defensive mechanisms of the UWSN. We expect it can offer a theoretical reference for the establishment of the UWSN security system.
