Security Loopholes and Privacy Concerns: Challenges in IoT Framework
Recently, IoT has emerged as an important topic of research in which physical entities are interconnected to each other through existing network topologies to achieve better communication with high accuracy and less power consumption. With the rapid progress of digitization, the data that is being collected has increased along with mutual communication to recognize the external events and act accordingly without any human intervention. These limitations that arise due to big data can be solved through the deployment of cloud-based technologies.
The advantages of IoT are almost limitless with its extended applications nearly changing the work lifestyle, and providing new opportunities for innovation, growth, and data sharing amongst the entities.
However, the existence of a vast communication network amongst entities will pose certain limitations such as trust, privacy and, security breaches. These limitations should be addressed before the deployment of a communication network. Although companies state that their technologies are secure and protected, they are still prone to different types of attacks. Also, the data which are being transferred comprises of user-related confidential information—the security protocol derived should be well defined with proper infrastructure, and latest techniques to mitigate all the security challenges concerning data integrity, privacy, and availability.
There are numerous communication networks available to achieve data transformation amongst the devices. RFID, WSN, and cloud technologies are frequently used data transmission techniques due to their low cost, minimum power consumption, and better storage availability through smart techniques.
Moreover, the vulnerability issues that are frequently affecting the performance of IoT systems are mainly because of interfacing issues, which may arise due to the insecure web interface. Insufficient authentication with weakest possible generic login credentials may result in loss of data or corruption. During data transfer, the encryption protocol designed should be secure enough to hide the credentials sent through the network. Furthermore, with some IoTs maintained by third party users, inefficient authentication may result in providing insecure network services to the clients.
With the emergence of cloud-enabled devices, attackers have developed multiple vectors for insufficient authentication, hacking transport encryption, and account enumeration to achieve control over cloud platforms. Furthermore, enforcing outdated password policy and granular permissions allow attackers to gain control over user authenticated data easily.
Implementation of a secure framework with bidirectional communication control firewall helps in minimizing the security threats and data theft by hackers. Furthermore, integrating vulnerability scanners along with authentication protocol during data transmission path enables high-end security at both transmission and receiving end of the user.
