Challenges in Security, Privacy and its Countermeasures - An IoT Perspective

In Digital transformation era, the expected trends in the technology put forward to the rise of Internet of Things. Contributing the data in web-based applications is increasing in now-a-days scenario. Sharing the data via internet and storing the sensitive information in database is critical one. One of the major constraints with IoT is limited computing and memory that deals with real time applications hence possibilities of vulnerabilities is high. With fast growing technological aspects, threats and vulnerabilities are also commensurately growing. In day-to-day life most of the IoT devices are compromised with attacks so it is apparent to discuss the security issues with its counter measures. This paper elucidates the classification of various attacks occurs and ensuring the security to find the most prominent attacks. This paper discusses the extensive summary of classification of attacks based of IoT layered approach, Protocol based approach and cloud-based attacks along with its preventive measures.
