The users of NFV are provided with a framework thatsupplies different flexible network services in a dynamic way via the software-basedvirtualization of network functions in a single infrastructure. Nevertheless, NFV confrontvarious challenges of security which make it vulnerable to several cybersecurity threats. Inthis paper, a review of NFV has been provided by introducing many related works, discussingserious and potential security attacks on the NFV, and presenting the efficientcountermeasures for mitigating these attacks. Finally, several practical solutions aresuggested for providing a reliable platform for NFV
