PROPOSED ACCESS CONTROL AND SECURITY ARCHITECTURE BASED ON FOG COMPUTING FOR IOT ENVIRONMENTS

As the Internet of Things (IOT) has grown in popularity it will be the Internet of the future, as seen a significant increase in smart homes/cities, smart connected vehicles, wearable technology and smart grid. This paper proposes a new approach for securing IOT systems. Cloud models may or may not maintain a consistent level of security in line with increasing data traffic. Fog computing can be used to extend cloud computing services to the network's edge and connect to the Internet of Things to provide computing services to these devices. In this context, Proposed access control and security architecture has proposed for an IOT environment based on fog computing. This paper provides secure smart home architecture and firewall-aware cloud and security fog. To protect against unauthorized data access and internet threats, a firewall system connects the internet to the fog layers. Data logging, device communication, and data transfers are all logged and alerts are generated if any misuse or suspicious communication patterns between the nodes are detected. In a Fog Cloud, IoT access control issues can be solved using the XACML language (eXtensible Access Control Markup Language). Privacy Level compared among the normal IoT environments, Cloud based IoT environments and Fog based IoT environments, which results the privacy of Fog based IoT environments is having high privacy and security. As a result, this security system will enhance customer confidence in smart home technology.
