الملخص EN

The appearance of Network Functions Virtualization (NFV) has provided a revolution in various network-based applications owing to its different advantages like manageability, flexibility, security, and scalability.

The users of NFV are provided with a framework that supplies different flexible network services in a dynamic way via the software-based virtualization of network functions in a single infrastructure.

Nevertheless, NFV confront various challenges of security which make it vulnerable to several cybersecurity threats.

In this paper, a review of NFV has been provided by introducing many related works, discussing serious and potential security attacks on the NFV, and presenting the efficient countermeasures for mitigating these attacks.

Finally, several practical solutions are suggested for providing a reliable platform for NFV
