This paper provides an insight into the latest security research trends, which will prove beneficial in the development of IoT security. The research outcomes can benefit the research community in IoT by integrating IoT-based devices' best security aspects. Lately, the entire network domain is undergoing a drastic technological revolution.
Automation of networks has been a hot topic that has been trending for quite some time. Supplementing it is Internet of Things IoT technology, which paves the way for providing that element. The Internet of Things [ 1 ] is defined as the inter-device environment built up by the devices that focus on three important tasks—transmitting data, receiving data, and processing received data.
Initially, local physical devices connected to the internet for real-time data analysis were considered being the IoT network. With time-lapse, IoT's scale has extended itself from the local workstation to Industrial IoT frameworks [ 2 ]. Research works on IoT depict the proliferation of IoT in the field of—healthcare [ 3 ], industrial setup [ 4 ], business analytics, education, etc. As of , IoT, which used to work at smaller network spaces, has upgraded for wide area networks, and so have the risks relative to it because of the expected surge in IoT devices in a diversified environment.
The primary purpose of this research work is to explore the latest security solutions in the IoT. Besides this primary goal, sub-goals comprise identifying and characterizing the latest security risks in the IoT.
Before that, it is important to address the recent research challenges in IoT-. Trending technical domains like Artificial Intelligence as cluster-based fuzzy logic modules [ 5 , 6 ], Machine Learning, and Software Enabled Networking [ 7 ] have become the new research field for incorporating IoT.
A notable development in IoT is the addition of ultra-lightweight protocols [ 8 , 9 ] deployed for the core functioning and security reasons as well [ 10 ]. Today, when we talk about IoT security, the main emphasis is on the access control methods [ 12 ], encryption methodologies used for transient phases [ 13 ], and hardware-specific security solutions [ 14 ], and SQL related input based attack controls [ 15 ].
So, our research emphasizes the ever-changing security perspectives of IoT by giving IoT related security issues, proper definitions, classification, and searching for the solution present in the current scenario against them. The work has been motivated to explore security concerns in IoT based devices due to different IoT applications. First, to understand IoT's security aspect, it is important to have prior knowledge about the infrastructure we are dealing with; thus, we have discussed IoT architecture and made a comparative analysis of protocols and standards used in IoT.
Our second research contribution includes exploring all possible aspects of recent research being made in IoT security, which will prove beneficial in developing an IoT security framework. A thorough review presented in this survey focuses on prominent threats prevailing in current IoT systems, along with the latest security models proffered for the IoT environment in recent years.
The purpose is to define security solutions in IoT's security requirements: confidentiality, integrity, authenticity, and trust management [ 16 ]. Our third research contribution comprises the identification and comparative analysis of prevalent protocols and standards in the IoT.
Research findings show that IoT security solutions are addressed by using existing encryption techniques and novel security design models. The major security issues recognized are trust and integrity of communication.
We also discovered a need for standardization at the manufacturing level, which shows the vulnerabilities at the hardware and software levels [ 20 ]. Inspections also revealed a need for protocols competent enough to accord for over one threat vector [ 21 , 22 ]. The research outcomes can help the IoT research community by integrating the safest appropriate security features in IoT-based devices.
The paper is organized as follows. Wireless network with embedded networking capability is the current Industrial trend worldwide. IoT is one of the main gainers of this networking domain. IoT Commercial sectors have seen a major boom in the market during the last few years, as smart system demands grew manifold because of its rich feature and one-click-away services.
Smart systems like Smart Home appliances, AI-based smart devices, smart home automation, smart vehicles, smart labs, etc. Estimated census of Wireless Devices [ 23 ]. The technical report suggests IoT devices have become the new source hotspot for intrusion activities for the hackers as the protocols and standards existing on these devices are mainly lightweight protocols [ 24 , 25 ] and, on the other end, entities constituting it has more accessible access to the server [ 26 ].
These pose challenges to the technology as there is no proper addressing of the security for the latter. It is observed that threat structure is not confined to a particular layer in IoT architecture [ 27 ]. Table 3 comprises a set of recent novel models proposed in the wake of advanced threat reports coming for IoT.
We have defined the security parameter concerning which certain research work offers a security model pertaining to conventional security models. The conventional model issue was—Inter-Compatibility among security tools deployed for IoT devices as they differed in Policy and implementation techniques and lack of Low- Powered device algorithms [ 28 ].
Recent research has proposed novel solutions using a different plethora of encryption methods and hardware-based methods [ 29 ] to overcome conventional security issues. Table 1 discusses some of these significant security models currently in research. Xin Zhang and Fengtong Wen [ 30 ] proposes a novel anonymous user WSN authentication for the Internet of Things wherein two algorithmic models UDS user-device-server and USD user-server-device , are constructed to ensure valid authentication for resolving trust centric threat models.
This is a multi-functional method to provide security during the authentication process with lighter storage overheads, efficient communication costs, and faster computational speed. This work is limited in terms of the extent of the security solution provided, only for the lightweight sensor devices against the prominent network layer and physical layer based attacks.
A cluster-based fuzzy logic implementation model is proposed by Mohammad Dahman Alshehri and Farookh Khadeer Hussain [ 31 ] and a secure messaging paradigm between IoT nodes where encrypted communication takes place utilizing hexadecimal values to cope with Port Scanning threats and other integrity specific vulnerabilities for AI-based IoT security solutions.
This work effectively proffers the detection mechanism against the malicious IoT nodes present in the network, but risks pertaining to the data audit attack surface are not covered in this model.
This study also falls short of addressing the performance analysis relative to communication costs and computation costs occurring in operation. Priyanka et al. However, there is a lack of clearance on the increased data overheads generated during the process.
Computational cost is another issue concerning this model. Two primary methods—data encryption and authentication have been used for this purpose, which has proved their efficiency in securing communication phases. This work gives valuable insight into the effectiveness of the cryptographic methods in securing communication channels. On the contrary part, this study states the inconsistency between the performance metrics and the cryptographic functions.
Deep learning and Machine learning have made their insight in IoT environment with major products being Alexa, Echo, which abject the text commands and takes voice-over commands for action on a real-time basis. But issues have arisen pertaining to the data packet leaks, and thus for that perspective, a voice recognition application is proffered by Pooja Shree Singh and Vineet Khanna [ 32 ], which is based on Mel-frequency cepstral coefficients MFCC for user identification and authentication deployable in the IoT environment to ensure data integrity, confidentiality, and privacy security.
This work is useful for securing voice-enabled IoT applications; however, large dependency on the hardware architecture required for the noise-free and quality input is its major down-point. IoT has struggled with access control-related problems ever since its arrival. To address this problem, Michail Sidorov et al. Performance analysis depicts promising results with lesser storage costs and high computational speed.
This work is believed to impact secure IoT devices significantly; however, the entire setup cost is uncertain. Chen et al. This work is useful in refining the attack surface due to its low rate signal detection method. It features scalable architecture as it covers both cloud computing and edge computing IoT devices, which is an advantage, but larger storage overheads remain an issue. Extension of which in IoT perspective is some proposed model like Snort [ 35 ], Suricata [ 36 ], and Bro [ 37 ].
Roesch [ 35 ] and Paxson [ 37 ] talks about the model resulting from pattern-matching monitoring. Suricata [ 36 ] is modeled on the semantic level matching of the network activities.
Paradoxically, such models are designed for professional use and are not explicitly aimed at the IoT environment in terms of protocol analysis availability.
It targets such advancements for expert users but not a regular citizen who lacks knowledge of the whole framework technology's technical know-how.
GHOST [ 38 ] is a Development project Safeguarding home IoT environments with personalized real-time risk control that challenges the conventional network security solutions for the IoT by proposing novel reference architecture.
This model's feature is—embedded network environment in an adequately adapted smart home network gateway and is vendor-independent. The issues regarding this integrated model are many attacks like impersonation attacks, offline password attacks, and hardware-based anomaly attacks still pertain to pose a threat to the whole architecture.
As discussed earlier, IoT operations are constructed out of three major functions, for example, transmitting, retrieving, and processing data. IoT is a technology comprising data exchange between heterogeneous devices that continuously stream information data among other peripheral devices. Internet of Things has a multi-layer and multi-plane architecture, as shown in Fig. It comprises the following component sections—Device Management section, Application Interface section, and Communication plane.
Application Interface Layer—Devices interact with underlying architecture via certain embedded interface modules like Arduino IDE, Raspberry Pi, sensors, actuators, etc. For instance, Aggregator—is a centralized component that aggregates the data in fluxed from the devices.
Communication Layer—this layer is the intermediary layer that comprises switches and similar network units that define the communication protocols and standards for the IoT network traffic.
This layer consists of protocol stacks of the latest protocols and standards implemented to direct network traffic in the entire system. New diversified communication protocols used in embedded IoT environments are energy efficient, have better congestion control properties, and have improved QoS features. Such an environment needs to have some sort of standardized set of rules which initialize easier and is compatible enough for info sharing.
Notably, the communication protocols of IoT are:. Its low energy consumption capability makes it suitable for low energy devices. This protocol is based on Generic Attributes, and it operates via services and characteristics. This protocol working is based upon three major components, namely—Publisher, Broker, and Subscriber. The publisher is the one that only transmits the data; the Broker is the intermediary MQTT server that analyzes the data being sent, and the request is identified for certain resources, and last, the subscriber, these components are the receiver of message coming from the broker.
It is better suited for working in multi-client environments, as it supports multi-functions by making servers handle immediate requests faster. Constrained Application Protocol CoAP [ 44 ] — as the name suggests, it is a constrained based environment protocol. This protocol's significant characteristics are—based on the REST API structure, designed for smart system applications, well-designed congestion control, cross-protocol integration, and many more.
Data exchange is possible via the publish-subscribe method, as in MQTT and CoAP protocols, the only difference being that it is broker less architecture, unlike the latter ones. It uses multicasting to bring high-quality QoS to the applications.
With such a prognosis, the technology is predicted to step far ahead than anyone can possibly imagine. But with the rise in popularity of IoT devices , there will be a rise in IoT app development as well as security challenges and issues. Source: Statista. In October , a hacker found a vulnerability to a specific model of security cameras. Nearly , Internet of Things IoT video recorders started to attack multiple social network websites and brought down Twitter and other high-profile platforms for almost two hours. This attack is just an example of what can happen to IoT devices with poor security.

On November 29, , the U. The tasks identified in the Road Map tie together multiple streams of effort across government and industry. Many proposals are global in nature, will continue to evolve based on the threat environment, and — in order to be successful — require substantial participation from the private sector. In short, the Road Map envisions a long-term whole-of-ecosystem effort to mitigate the threat posed by botnets and distributed denial-of-service DDoS attacks.
Vulnerabilities in the communications protocols used by millions of Internet of Things IoT and operational technology OT devices could allow cyber attackers to intercept and manipulate data. These ISNs are designed to ensure that every TCP between two computers or other internet-connected devices is unique and that third parties can't interfere with or manipulate connections. In order to ensure this, ISNs need to be randomly generated so an attacker can't guess it, hijack it or spoof it.
Миллион песет? - предложил Беккер. - Это все, что у меня. - Боже мой! - Она улыбнулась. - Вы, американцы, совсем не умеете торговаться. На нашем рынке вы бы и дня не продержались. - Наличными, прямо сейчас, - сказал Беккер, доставая из кармана пиджака конверт.
Чем глубже под землю уходил коридор, тем уже он становился. Откуда-то сзади до них долетело эхо чьих-то громких, решительных шагов. Обернувшись, они увидели быстро приближавшуюся к ним громадную черную фигуру. Сьюзан никогда не видела этого человека раньше. Подойдя вплотную, незнакомец буквально пронзил ее взглядом.
Но он прошел Сквозь строй. - Если эта система его не перехватила, то откуда вы знаете, что вирус существует. Чатрукьян вдруг обрел прежнюю уверенность.
Никакой Северной Дакоты нет и в помине. Энсей Танкадо - единственный исполнитель в этом шоу. Единственный исполнитель. Сьюзан пронзила ужасная мысль. Этой своей мнимой перепиской Танкадо мог убедить Стратмора в чем угодно.
Дэвид кивнул. - В следующем семестре я возвращаюсь в аудиторию. Сьюзан с облегчением вздохнула: - Туда, где твое подлинное призвание.
Но, директор, ведь это… - Риск, - прервал его Фонтейн. - Однако мы можем выиграть. - Он взял у Джаббы мобильный телефон и нажал несколько кнопок.
Мы с мисс Флетчер пробудем здесь весь день. Будем охранять нашу крепость. Желаю веселого уик-энда. Чатрукьян заколебался. - Коммандер, мне действительно кажется, что нужно проверить… - Фил, - сказал Стратмор чуть более строго, - ТРАНСТЕКСТ в полном порядке.
Я еле добрел. - Он не предложил вам больницы поприличнее.
