Current Security Threats in Applications of Wireless Sensor Network

Wireless sensor networks have a broader application range in almost every field of human endeavours, which exposes them to a variety of security threats on a daily basis from cyber criminals. It is a remote monitoring system for events or phenomena in areas such as smart grids, intelligent healthcare, circular economies in smart cities, and underwater surveillance. Cybersecurity threats have long been a source of concern in the field of wireless sensor networks. The goal of cyber security in this era is to certify the authenticity of networks confidentiality, data integrity and availability of network assets. Various security mechanisms, particularly key management cryptographic, authentication mechanisms, and intrusion detection systems have been developed from several machine learning algorithms, and so on, which have been used to ensure network security. In this paper, we focused on outlining diverse application areas of wireless sensor networks with their security threats, major challenges and given some common mechanism to counter security threats for in-depth research insight on security in applications of wireless sensor networks. In addition, an analysis of the common attacks on wireless sensor networks has been provided.
