Security analysis as software-defined security for SDN environment

The security of cloud environment is always a target for attackers in order to exploit any of the system's vulnerabilities. Recently, software-defined systems (SDS) has become a focus of several researches. Where, SDS is in the way to replace the traditional networking, in order to provide facilities which are based on remote and centralized control. The security of SDS is a major requirement to guarantee the integrity, confidentiality and availability of data and the communication. This paper presents a security analysis as a software-defined security service that enforces the security within the SDN in the cloud environment. The security analysis is specified through the attack graph and alert correlation clustering, which aims to enhance the work of other security approaches such as IDS by giving a global view and hint about the security state of the environment, also by reducing the rate of false positive alerts.
