B. A User-Centric Approach A user-centric model to protect users’ securities in NFV is introduced by Montero, et al. [10]. In the model, the security is ensured by a trusted virtual domain located in the access network. An architecture named SECURED is presented to afford a safe environment for providing secure

Main components of the SECURED architecture include security module, security policy manager, authentication system, and SECURED app. These security related components work together to provide security and trust in NFV. C. OpenNF It is designed as control plane architecture to provide efficient and safe allocation of data flows across network function instances in NFV [6]. OpenNF provides efficient, coordinated control of both internal network function state and network forwarding state. It overcomes the existing challenges for secure NFs control. It addresses the race conditions problem, bounds the overheads, and uses the least changes to accommodate many different VNFs. The aim of OpenNF is providing security and flexibility for VNFs control in NFV with minimum overheads. D. Cisco Evolved Services Platform Cisco Evolved Services Platform (CESP) was introduced as a secure and low cost NFV solution in 2014 [33].The Service Broker connects services orchestration and business logic to assure efficient and secure service delivery. Different service attributes and policies are included in service profiles to enable secure and dynamic delivery of personalized services. The Catalog of Virtual Functions defines available VNFs and services to customers. The employment of OpenStack [34] to the open architecture makes the Catalog of Virtual Functions extensible, which allows more VNFs and services to be added into the NFV solutions [35], [36]. E. VMware vCloud NFV It was developed by VMware in 2015 to cope with increased service agility and security. The VMware vCloud Director for Service Providers allows secure Communication Service Providers (CSPs) commercial scale deployments. The VMware Integrated OpenStack is responsible for QoS and placement of VMs. It guarantees the performances of VNFs and makes the OpenStack clouds more scalable, secure and resilient. The VMware vRealize Operations Insight assures network functions and services for multiple tenants. VMware NSX realizes the benefits of NFV and VMware Sight Recovery Manager enables disaster recovery and business continuity [37]. F. Alcatel-Lucent CloudBand In 2014, a secure NFV platform called CloudBand id developed by Alcatel-Lucent [38]. The framework of CloudBand includes a centralized CloudBand management system and multiple distributed CloudBand nodes [39], [40]. To provide secure VNFs, the CloudBand management system manages and orchestrates resources in the NFVI, and affords processing and analysis for historical and real-time data, such as anomaly detection and event prediction [41].

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
