Recently, the idea of Internet of Things is seeking much attention because of its vast potential in the area of wireless transmission. IoT interlinks plentiful of heterogeneous, geographically diversified devices which usually have scarcity of resources, and therefore rely on cloud for the same. Unfortunately, the Cloud enabled IoT suffer from various limitations say, high network latency with the increase in volume of data processed. Due to the above limitation, majority of latency sensitive applications tend to provide poor performance. To alleviate this problem, the concept of Fog Computing came into the picture, in which Fog level is introduced as an intermediary level between Cloud and IoT devices. IoT unlocks handful opportunities for various sophisticated applications such as home applications, wearable devices etc. and also allow sharing of data over internet. This data being shared contains large amount of sensitive information that should not be shared amongst the connected users. In this paper, firstly brief overview about fog computing is provided and subsequently various security issues pertaining to both Fog and IoT environment are defined.
