Security in SDN: A comprehensive survey

Journal of Network and Computer Applications, 2020
Software Defined Networking (SDN) is a revolutionary paradigm that is maturing along with other network technologies in the next-gen trend. The separation of control and data planes in SDN enables the emergence of novel network features like centralized flow management and network programmability that encourage the introduction of new and enhanced ...

Leveraging LTE security with SDN and NFV

2015 IEEE 10th International Conference on Industrial and Information Systems (ICIIS), 2015
In this paper, we study the current and emerging security mechanisms to protect the LTE (Long Term Evolution) architecture. We also highlight the limitations of legacy LTE security mechanisms. SDN (Software Defined Networking) and NFV (Network Function Virtualization) are positioned as innovative concepts to improve overall LTE security posture.

A secure computation framework for SDNs

Proceedings of the third workshop on Hot topics in software defined networking, 2014
Software Defined Networking (SDN) introduces a logically centralized control plane to run diverse management applications. In practice, a logically centralized control plane is realized using multiple controllers for scalability, reliability, and availability reasons.

A comprehensive security architecture for SDN

2015 18th International Conference on Intelligence in Next Generation Networks, 2015
SDN enables the administrators to configure network resources very quickly and to adjust network-wide traffic flow to meet changing needs dynamically. However, there are some challenges for implementing a full-scale carrier SDN. One of the most important challenges is SDN security, which is beginning to receive attention.

Securing middlebox policy enforcement in SDN

Computer Networks, 2021
Abstract Software-Defined Networking (SDN) greatly simplifies middlebox policy enforcement. Middleboxes need tag packet headers to avoid forwarding ambiguity on SDN switches. In this paper, we present a new attack, called middlebox-bypass attack, to breach SDN-based middlebox policy enforcement.

Towards A Secure SDN Architecture

2018 9th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2018
Software Defined Networking (SDN) is an emerging technology which is widely accepted by various enterprises. The SDN mostly involves with a programmatic interface which replaces the control plane on the switch and provides a programmatic interfaces into the controller, to network orchestration in general.

Securing distributed SDN with IBC

2015 Seventh International Conference on Ubiquitous and Future Networks, 2015
In distributed software-defined network (SDN), the east/west-bound protocol describes the communication between the SDN controllers. The security of the east/west-bound protocol ensures that no malicious controllers are eavesdropping on or even driving the network.

SDN-based security mechanism

2015 14th RoEduNet International Conference - Networking in Education and Research (RoEduNet NER), 2015
Nowadays most hardware configurations are being replaced with software configurations in order to virtualize everything is possible. At this rate, in the networking research domain, the concept of Software Defined Network (SDN) is evolving. This paper proposes an SDN-based security mechanism that provides confidentiality and integrity by using custom ...
