Improvement of Security in IOT Sensor Network to Overcome Harmful Intruder by Optimizing the Existing Techniques

Internet of Things is the web of physical devices acquired through the Internet. These devices contain entrenched technology to connect with both internal environment or the external status. Internets of Things (IoT) devices are directly becoming ubiquitous while IoT services are becoming global. Cyber-intruders are not unique to IoT, but as it will be deeply merged in our lives and humankind, it is becoming essential to step up and take cyber protection seriously. With increasing use of it in diverse fields has improved the demands of various parameters, for an excessive degree of security and applications. In this paper, we have compared the variance in security features of new technology like Low-Power Wide Area (LPWA) network technologies: LoRaWAN and NB-IoT. The security features of every technology are specified in a comparison to demonstrate that security won't be the determining aspect while choosing on a LPWA technology. We describe the exceptional contributions that every characteristic makes the general security of a device and emphasize how the security functions may not or might be appropriate in our option of a LPWA technology, based on the designed use case. We consider whether the security functions of each technology are appropriate for a fixed of use cases representing standard deployments for every technology. Based on an assessment of an appropriate feature, we have calculated the performance of the security in each technology and the each use instances. After identifying the security problems in IoTs, this paper suggest answers from present technologies as a start line for establishing a standardized security paradigm in IoTs.
