Benefits of IoT
IoT or Internet of Things can be defined as the typical networking of all types of home appliances, electronics, sensors, software items, physical devices or vehicles (Vlacheas et al. 2013). The proper connection of this Internet of Things is responsible for enabling the various things for the proper connection or even exchanging the confidential data. There are some of the major and most significant benefits of Internet of Things, which make this technology extremely popular and well accepted by all (Yahmadi 2015). However, few issues are also incorporated within this technology.
This literature review will be outlining a detailed discussion on the security of internet of things. Various popular and significant issues are present that make the security of this particular technology. The subsequent failure of any type of strong password is the considered as the most important and significant issue for the security of the Internet of things. The proper definition of IoT, including the several issues with the relevant solutions of those security issues will be provided here.
According to Zhao and Ge 2013, Internet of things or simply IoT can be defined as the most vital systems for various inter linked digitalized machines, computing devices, mechanical machines as well as objects or many others that consist of the main ability to get the UID or unique identifier. Another important characteristic of this technology is that no proper interaction is present between the human and computer systems (Singh, Tripathi and Jara 2014). This type of interaction is not needed within the technology. The proper evolution of the technology of IoT has taken place from machines to machines or M2M communications, in which these machines are being connected with each other by the help of a typical network that does not have any human interaction. This Internet of Things eventually takes up the significant communication of machine to machines to another important level and even the sensor networks for the several smart devices that are being linked with the applications, people and even the systems for properly collect or share the data. As per Perera et al. 2014, this communication of the M2M or machines to machine has the core responsibility for providing the significant connection that could be easily enabling the technology of IoT.
There are various important and significant advantages of the technology of IoT within any specific business are given below:
- i) Monitoring Business Operations: The most important advantage of the technology of IoT is that this technology can eventually monitor the several business operations within any particular company (Dastjerdi and Buyya 2016). For the presence of this benefit, the issues are easily observed as well as mitigated.
- ii) Improvises the Experience of the Customer: The next significant advantage of the technology of IoT is that it helps in the proper improvisation of the various customers’ experiences.
iii) Enhancing Productivity of the Employees: Aazam et al. 2014 state that another specific and vital benefit of the IoT technology is that it helps in properly enhancing the complete productivity of the employees within any particular organization.
- iv) Makes Business Decisions even Better: The fourth benefit of the technology of internet of things is that it helps to make the business decisions even better (Vermesan and Friess 2014). This is mainly because the any type of human interaction is completely avoided in the procedure and thus the several goals or objectives of a company are properly achieved.
- v) Saves both Money and Time: The technology of Internet of things is also much effective in case of saving money or time. Hence, the major resources of the organization are eventually saved by this specific technology (Raza, Wallgrenand Voigt 2013).
- vi) Integration of Business Models: The next vital benefit of the technology of internet of things is that it helps in proper integration of each and every business model. According to Computing 2017, several business models are present within a company and for properly managing those business models, the integration is highly important.
Palattella et al. 2016, state that although, the above mentioned factors demonstrate that the technology of Internet of Things comprises of numerous important benefits, it do comprise of few nefarious issues related to security. This often becomes a major issue for the organization regarding the security. The most important security issues of the IoT technology are as follows:
- i) Lacking of Encryption of Data: The first and the foremost issue that is extremely common for this technology of Internet of Things security is subsequently lacking the encryption of any type of confidential data (Tsai et al. 2014). This technique of encryption enables the several users in keeping their sensitive data secured as well as protected. This particular technique makes the data hidden by converting it to an encrypted one. Thus, data retrieval and data processing must be saved perfectly. The technique of encryption significantly develops a data shield and hence protecting the data from all types of unauthenticated accesses (Granjal, Monteiro and Silva 2015). In spite of the fact that IoT has several advantages, the typical facility of data encryption is not present here. With this security issue, the data integrity and confidentiality are being lost.
- ii) Losing Authentication of Data: According to Madakam, Ramaswamy and Tripathi 2015, the authentication of data can be defined as the specific process that helps to provide only appropriate as well as authenticated information to its users. The authenticated information is completely appropriate and correct and hence unauthenticated access is almost absent here. The technology of IoT, although is the best as well as an important technology, still cannot provide authorized and authenticated information (Keoh, Kumar and Tschofenig 2014). False data is often provided in this particular technology and hence it becomes easier for the hackers in accessing as well as modifying that data.
iii) Data Plane Attack: As per Karagiannis et al. 2015, the next security problem of the technology of IoT is the attack of data plane. There are distinct two portions within the Internet of Things that are data plane and control plane. This data plane attack occurs within the specific data plane routers. The major issue starts when these packets get forwarded. There are various vulnerabilities of software for the processing of devices. These vulnerabilities are important and hence these are responsible for exploiting the data plane of IoT (Raza, Wallgren and Voigt 2013). This type of exploitation is majorly done within the software of packet processing for the core purpose of launching the types of nefarious denial of service attack in the infrastructure of network.
- iv) Side Channel Attack: Another important and significant dangerous or nefarious attack, present within the Internet of Things technology is the side channel attack. All these types of side channel attack occur, only when there few issues related to authentication as well as encryption is being present. Furthermore, all of these attacks also focus less on the information or data and even on the procedure that how that data is being processed (Dastjerdi and Buyya 2016). Whenever any attacker is accessing sensitive data like timing information, electromagnetic leaks and power consumption, that particular attacker utilize this confidential information for the side channel attack.
- v) Hidden Channel Attack: As per Vermesan and Friess 2014, the next important and vulnerable attack of the Internet of Things technology is the attack of hidden channels. The various software bugs and even the cryptanalysis of the specific systems altogether work as one single system and next the significant internal operations of that system are being exploited easily. An extremely high technological knowledge is needed for this type of exploitation and thus the increase of the advanced or highly developed Web 2.0 application or SaaS model (Singh, Tripathi and Jara 2014). Furthermore, all of these attacks are even very common, whenever the complete transmissions get encrypted in the web server or web browsers.
Security issues of IoT
The above mentioned security issues are extremely significant and dangerous for any user and hence the vulnerabilities are increased eventually. These types of vulnerabilities or security issues are very common for the users of IoT.
Although, these types of security related issues are common in the technology of Internet of Things, there are some of the most relevant or appropriate solutions for all these problems (Vlacheas et al. 2013). The most relevant and significant solutions for the above mentioned issues are as follows:
- i) Solution toLacking of Encryption of Data: This specific security problem is highly vulnerable for the various devices of the Internet of Things. The users are also affected in this scenario. According to Zhao and Ge 2013, to address the particular problem related to the lacking of encryption to the data, the most effective and effective method is use the protocol of Secure Sockets Layer or SSL, when the data remains on the Internet. Hence, the various web sites, which are subsequently using this certification of Secure Sockets Layer to properly encrypt as well as protect the confidential data of the users is being considered as one of the most secured websites. Furthermore, the respective wireless protocol side is even needed for getting it protected and secured (Raza, Wallgren and Voigt 2013). Hence, the sensitivity and confidentiality of the information like GPS is required for being accessible or available for these users. Thus, the most significant solution to the lacking of the encryption of data is by utilizing the wireless protocols with an inbuilt encryption technology.
- ii) Solution toLosing Authentication of Data: The next important security issue of Internet of Things technology is the losing of data authenticity (Madakam, Ramaswamy and Tripathi 2015). This type of issue should be resolved as soon as possible, so that the user does not get an unauthenticated data. This typical security problem could be easily solved by perfectly implementing sensors within the IoT smart devices. Although, this confidential data gets encrypted, it is directly transferred by simple authentication of the data sources and forged or false data are easily avoided in this case and appropriate data is promptly provided to these users (Keoh, Kumar and Tschofenig 2014). These sensors are extremely expensive; however they provide perfect data to its clients.
iii) Solution to Data Plane Attack: According to Karagiannis et al. 2015, the attacks of data plane are very common for the devices of Internet of Things. All of these attacks can be easily solved by a perfect combination of cloud computing as well as internet of things technology. With the proper utilization of the cloud computing, the various packets of the confidential data plane eventually go through current router and hence all the attacks could be ceased easily.
- iv) Solution toSide Channel Attack: This side channel attack is the most vulnerable and important for the security purposes. Hence, it becomes very common for the devices of IoT. The wireless networking is thus used for stopping such attacks (Granjal, Monteiro and Silva 2015). The SDN or the software defined networking is another important method for encompassing the various issues related to IoT security and hence this virtualized servers or the infrastructures of storage are protected eventually. Thus, data protection is easily done here.
- v) Solution toHidden Channel Attack: This type of security attack can be promptly stopped by taking the help of the cipher algorithm of encryption. The plain text gets encoded to a cipher text and hence helps to maintain the confidentiality of the data (Yahmadi 2015). A secret key is present for deciphering the hidden data and hence all the issues are resolved.
Conclusion
Therefore, from this literature review, conclusion could be drawn that the technology of IoT is considered as the most significant and popular growth or advancement within the technological world. There are several significant applications of the IoT technology. These applications are then sub divided in three distinct categories that are enterprises, consumers and finally infrastructure spaces. This typical activity is responsible for creating the few opportunities to directly integrate as well as collaborate the physical world with the computerized system. For the massive involvement of the technology, some of the most significant security issues are present, which make the technology much vulnerable. Proper solutions should be used for mitigating such risks, so that the threats are well avoided. This literature review properly outlined a brief discussion on the security of IoT. Various risks are identified in the literature review with their relevant solutions.
