Internet of Things: Threats and Security

Aditya Bhardwaj; Abhishek Dadhich

Abstract

Security is the most important in today’s world as we have personal and confidential data which we do not want to share with anyone, but somehow attackers attack on our data and steal our identity. Same happens in IoT, attackers somehow attack on devices or communication channels and steal the data. This study reviews all the threats and security issues in IoT. Nowadays, devices are made in such a way that they have to store all the data of a user; so it is easy for an attacker to take away all the necessary data in one go. This study has a review of threats which comes in the way of IoT, security issues, and their solutions. Problems like covert channel, breaking of ASLR and KASLR, Keystroke timing attack, and some security frameworks. Network security is the critical part of today’s world, and operability and interoperability are key of IoT, but due to weak controllability and heterogeneity, all data expose to attacker. In IoT, data storing and processing is in underlying layer; due to this, data is exposed. Taking an example of MQTT it is light weight machine to machine communication protocol that acts as low bandwidth communication method. There is need of security to hide our data from attackers. IoT is the combination of different technologies so there is a chance of stealing of identity or data. IoT also produce data in large number which is also known as Big Data and Big data has its own security issues. Mobile devices are also used in IoT so they also increase security issues.
