data remains insecure, which is major security concern in the IoT network. Additionally, insufficient security configurability is also a concern for IoT infrastructures. In view of Mahmoud et al. (2015), insufficient security configurability is an issue that occur when a user of the system has limited capacity to change its security controls. This type of vulnerability is evident in situations where the web interfaces of different devices lack the abilities to create granular user permissions or for instance, compelling the usage of stronger passwords. Sicari et al. (2015) contend that IoT devices become easy targets for attacks by permitting unauthorised access to stored data or core components of the system. What is more, the lack of security logging, password security options, and security monitoring leave IoT systems exposed, which raises security concerns pertaining to the use of the infrastructure. In addition to configurability, insecure firmware or software is a network issue

Internet of Things 5 when it comes to IoT. According to Ning, Liu, and Yang (2013), the inability of IoT devices to be updated is a critical security concern on its own. Notably, the authors assert that devices ought to have the capacity to stay updated whenever vulnerabilities are exposed. In light of this, it is possible that firmware/software updates can be left unprotected when the updated files themselves or the network connections they are delivered on, are insecure. Moreover, firmware or software can be a security concern if they have hardcoded confidential information such as user credentials. Li, Da Xu, and Zhao (2015) note that the incapacity of firmware/software to be updated implies that devices stay exposed indefinitely to security issues that updates were meant to handle. Furthermore, if devices contain hardcoded sensitive data and the information is exposed, then, it is likely that they will stay so for an undefined period. Other than the mentioned aspects, lack of update functionalities, encryption that cannot fetch updates, unencrypted update files, and unverified updates also result in insecure software of firmware, which have the potentials to compromise the security of IoT systems.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
