“…A number of related works have analysed the SDN or OpenFlow vulnerability and identified security threats (Eason et al, 2013;Kloti et al, 2013; ftp://ftp.tik.ee.ethz.ch/pub/students/2012-HS/MA-2012-20.pdf; Kreutz et al, 2013;Benton et al, 2013;Khurshid et al, 2012Khurshid et al, , 2013Jafarian et al, 2012;Kobayashia et al, 2012) and some of them also summarise general possible solutions to malicious attacks, such as FortNox and FRESCO (SDN Security Seminars, http://www.OpenFlowsec.org/SDN_SecuritySeminar_Feb2012.pdf; Porras et al, 2012;Shin et al, 2013aShin et al, , 2013b) that extends NOX (Gude et al, 2008) with a security kernel and security programming interface. Kreutz et al (2013) analysed and identified several threat vectors that may enable the exploiting of SDN vulnerabilities. They have summarised SDN security kernel work that was capable of ensuring prioritised switch flow rules for security related applications and for other all remaining applications.…”

Software-defined network (SDN) is proposed as a new concept in computer networks, which separates the control plane from the data plane. And it provides a programmable network architecture that could facilitate rapid network innovation. OpenFlow is a network protocol that standardises the communications between OpenFlow controllers and OpenFlow switches. It is considered as an enabler of SDN. The flow table in OpenFlow switches plays a critical role in OpenFlow-based SDN, which stores the rules populated by the controllers for controlling and directing the packet flows in SDN. Nevertheless, they also become a new target of malicious attacks. This paper analyses the flow table overflow attack, a type of denial of service attacks, and proposes a novel eviction algorithm, dynamic in/out balancing with least frequently used eviction (DIOB/LFU), at service level to defend against the flow table overflow attacks.

Abstract. With the development of the software-defined networking (SDN), centralized and open network management has brought many security problems. In this paper, we analyzed the security problems in SDN architecture, and then designed a SDN security controller architecture. We verified the feasibility and effectiveness of the architecture by using DDoS attack defense as an example, and analyzed the influence of the architecture on the network performance.

Resilience support in software-defined networking: A survey

et al. 2015

View full text Add to dashboard Cite

Software-Defined Networking (SDN) is an architecture for computer networking that provides a clear separation between network control functions and forwarding operations. The abstractions supported by this architecture are intended to simplify the implementation of several tasks that are critical to network operation, such as routing and network management. Computer networks have an increasingly important societal role, requiring them to be resilient to a range of challenges. Previously, research into network resilience has focused on the mitigation of several types of challenges, such as natural disasters and attacks. Capitalising on its benefits, including increased programmability and a clearer separation of concerns, significant attention has recently focused on the development of resilience mechanisms that use software-defined networking approaches. In this article, we present a survey that provides a structured overview of the resilience support that currently exists in this important area. We categorize the most recent research on this topic with respect to a number of resilience disciplines. Additionally, we discuss the lessons learned from this investigation, highlight the main challenges faced by SDNs moving forward, and outline the research trends in terms of solutions to mitigate these challenges . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 This article presents a survey on the support for network resilience in SoftwareDefined Networking (SDN). This has been the subject of intense investigation by the academic and industrial community in the past few years, as evidenced by the number of papers included in our survey (159 references in total). Capitalizing on the benefits of SDN, including increased programmability and a clearer separation of concerns, significant attention has recently focused on the development of resilience mechanisms that use software-defined networking approaches. Thus, a wide range of solutions to classical network problems have been revisited using this architecture, but many problems continue to be challenging.Our survey investigates the resilience support that currently exists in this important area, and categorizes the most recent research on this topic with respect to a number of resilience disciplines. Additionally, we discuss the lessons learned from this investigation, highlight the main challenges faced by SDNs moving forward, and outline the research trends in terms of solutions to mitigate these challenges. The aim of the survey is to offer to the reader a structured view of network resilience in the SDN spectrum, and how resilience aspects are supported in these architectures.We believe that this subject material is closely aligned with the objectives of the journal.
