Abstract: (2602 Views) |
Increased broadband data rate for end users and the cost of resource provisioning to an agreed SLA in telecom service providers, are forcing operators in order to adhere to employment Virtual Network Functions (VNF) in an NFV solution. The newly 5G mobile telecom technology is also based on NFV and Software Define Network (SDN) which inherit opportunities and threats of such constructs. Thus a thorough understanding of security challenges and their solutions are required to reduce security concerns while developing new services. In this article, cloud computing, NFV and its VNFs from a security perspective is explained. Then, their security challenges with respect to cloud computing infrastructure and current solutions are discussed in a comparative scenario based way. Finally, proper security solutions for each scenario are proposed.
