Introduction
Software-Defined Networking (SDN) has revolutionized the way networks are managed by separating the control plane from the data plane, allowing for centralized network management and programmability. In recent years, there has been a growing interest in applying the principles of SDN to security, leading to the emergence of Software-Defined Security (SDSec). SDSec enables organizations to dynamically adjust their security policies based on changing network conditions and threats in real-time.
Cloud computing has become increasingly popular due to its scalability, flexibility, and cost-effectiveness. However, securing cloud networks poses unique challenges due to the dynamic nature of cloud environments and the shared responsibility model between cloud providers and customers. Traditional security approaches are often not well-suited for the cloud, as they are static and lack the agility to adapt to the rapidly evolving threat landscape.
This thesis aims to investigate the use of Software-Defined Security Policies for Cloud Networks, with a focus on improving the security posture of cloud environments through dynamic policy enforcement and network segmentation. The research will explore how SDSec can enhance the security of cloud networks by enabling fine-grained control over security policies and automated response to security incidents.
