The promising IoT connects various kinds of devices through the Internet so as to reap data formulated by sensor(s), end devices connected at longer distance, buildings, vehicles, etc. [1]. In the last year, IoT devices have radically increased in number with variations and nearly 50 billion of them being connected to web by end of 2020 [2]. IoT devices are distributed across all environments and several kinds like “smart cities, grids, health, retail, watches, supply chain, farming, TVs, and so forth”. While designing IoT, important aspects to consider are security and privacy services. Unfortunately, there is a chance for the IoT devices to be inadequate or deficiently structured security systems. Moreover, security assaults can infiltrate into IoT devices and destroy the communications; hence, such security dangers must be aware of in IoT network.

In order to evade cyber assaults, during IoT devices design, security must be looked upon as a vital segment [3]. But, the various types of IoT constituents interrupt unfolding of well recognized techniques for reassuring Security in IoT systems [4, 5]. The foremost challenging aspects of IoT devices are quantification, energy, storage, and communication capabilities. Just about, it is very delicate to build cyber-security among the IoT end users and manufacturers. Incidentally, most of the IoT equipment companies hold lowered cost for actuator and sensors in the market. Such devices were primarily intended to operate in disconnected networks, where the security threats are substantially less prevalent.

As a consequence, some of the designer are not capable enough on cyber security and might be ignorant of the security dangers relevant to their real world devices. Hence, with the need to lower expenses and the time on advertisements related to IoT networks commercialization, security is overlooked [6].

The objective of this paper is therefore to focus on current IoT cyber security issues and get familiarized with the dangers posed by IoT devices. The paper discusses about the characteristics of such dangers and the possible infringements. The issues recognized with IoT related cyber security have been presented in various works in the literature as in, e.g., [7–9]. As compared to such papers, here, we address the theme from an increasingly down to earth viewpoint. Commonly, “Zigbee, 6Lo-WPAN, LoRa-WAN, and Bluetooth Low Energy” are eventually utilized as communication protocols in IoT devices.

We quickly review the security methods supported by every protocol and, consequently, investigate the attack surface, additionally revealing a progression of genuine assaults against eminent business IoT devices as instances of the dangers related with inadequately planned security components. Moreover, we depict the “formulating units, communication protocol, and cryptographic equipment, and programming” utilized around business arrangements, to bestow preparatory processes as of now embraced in the market. This examination would then be able to be valuable to readers and specialists intrigued to get a handle on the more functional ramifications of IoT security.
