sdn security challenges and solutions

This paper describes several threat vectors that may enable the exploit of SDN vulnerabilities and sketches the design of a secure and dependable SDN control platform as a materialization of the concept here advocated. Statistical analysis b. Although most of the work was related to traditional networks, the models are applicable to the fundamental structure and architecture of SDN [5]. 2014. Blessing or curse? Support vector machines: This is among the mostcommon machine methods for classifying machine learning tasks. [5] Ashraf, J. and S. Latif. While the higher level of visibility with SDN improves some aspects of security,like most technological advances, it also introduces new vulnerabilities. Since the controller is centralized, it will be apotential single point of attack and failure. [12] Sousa, P., Alysson B., Miguel C., Nuno F., Paulo V.,Highly, Available Intrusion-Tolerant Services with Proactive-Reactive. Then classify attack pattern, attack type as well as the normal network behavior. An Orchestrator-based architecture that utilizes Network Monitoring and SDN Control functions to develop security applications was also proposed for OpenSec security implementation of SDN[11].The concept of proactive-reactive recovery presents a design paradigm for a generic proactive-reactive recovery service that can be integrated in any intrusion-tolerant system [12]. in Local Computer. Protecting the availability of network functions. in Next Generation Networks and Services. Bayesian networks: The Bayesian network scheme is builton the nave Bayesian algorithm which is used primarily for learning tasks, where training set with target class is provided. What Is OpenFlow? In some papers [5], [9], thepurpose and the strategies employed by attackers to exploit the vulnerability of SDN based networks are clearly pointed out. "We need to be fair to our audience, to our target customers not everything is an XDR, Trellixs Chief Product Officer Aparna Rayasam said. We commence with a brief literature review and trends on SDN, and conclude with possible solutions, and suggestions on the way forward regarding the research for a secure software defined network. Tampering: In tampering attacks, an attacker attempt to get the system to modify a given data item from its original form to a form that meets the attackers need.This could be achieved by getting the controller to install flow rules intended to modify or falsify data packets or flow counters[17].c. Networks (ICIN), 2015 18th International Conference on. in Intelligence in Next Generation. We venture further into the horizon of the unknown to predict and identify new security breaches and threats, as well as areas of inherent weakness in the overall SDN architecture and infrastructure. Networks (LCN), 2010 IEEE 35th Conference on. - Select n attribute characteristics. Ensure the availability of network services.

Decision is also made on which security level, e.g. But many IT teams find the process of actually segmenting the network and mapping out system permissions more difficult than expected. Signature detection technique: This involves the use of special algorithm to search network traffic for the presence of packets sequences that are known to be malicious.b. In SDN environments, SDN network security needs to be everywhere within a software-defined network (SDN). The Spanning Tree Protocol functionality that how it works and what are its advantages and disadvantages, STP is used as a POX SDN controller component, and the working of STP with SDN is main focus. blockchain deployments enhancing 2013. This paper presents an approach to secure the northbound interface by introducing a permissions system that ensures that controller operations are available to trusted applications only and implementation of this permissions system with Operation Checkpoint adds negligible overhead and illustrates successful defense against unauthorized control function access attempts. in Information Security (ASIA JCIS), 2014 Ninth Asia Joint Conference on. [26] Diego Kreutz, F.M.V.R., Paulo Verissimo Towards Secure and Dependable Software-Dened Networks, in HotSDN13. he apparent rigidity and lack of flexibility and programmability of legacy network architecture has been the concern of many networking enthusiastover the years. SDxCentral employs cookies to improve your experience on our site, to analyze traffic and performance, and to serve personalized content and advertising relevant to your professional interests. Denial of service: DOS attacks are designed to limit thesystems ability to transmit and received data in a normal and predictable manner. These massive, complex, and sensitive data and user requirements beckons on a new improved, dynamic and dependable network infrastructure and architecture which is promised on the centralized control based architecture of SDN. Explore the role this rising technology has played.

The aim of this paper is to describe a novel mechanism that provides an increase of resilience in SDN using a component organization and show that it is possible to build management applications resilient to diverse types of failures using component organization approach. Fuzzy logic: Because of the variability of the anomalousconditions of possible network intrusions, the notion of fuzzy logic is well suited to the design of intrusion detection logic in network security [5], [18]. Lightweight DDoS flooding, attack detection using NOX/OpenFlow. Implementation challenges for software-defined networks. Communications Magazine, IEEE, 2013.51(7): p.36-43. difficulty of execution.-Propagate values up the tree and make calculations based onspecific model.Sequel to the analysis of the above algorithm, Kloti pointedout a danger in the quantitative modeling of the attack tree, reasoning that the uncertainty of the leaf node values would rather support a variable probabilistic model rather than a precise quantitative model. Explore Jacobs' thoughts on SDN controllers and security. SDN provides an application programming interface (API) allowing a networks data plane to be altered by external applications.

Take advantage of network analytics to better understand how traffic is moving through the network and detect any anomalies that might indicate an intrusion has been attempted. 2014 IEEE 22nd International Conference on Network Protocols. DT constructs easily interpretable models that assist network security operatives to inspect and edit network records and reports [4].The separation in SDN of the functional network units as discussed in the introduction of this paper is key to the desired flexibility of SDN, breaking the network control problem into tractable pieces, and making it easier to create and introduce new abstractions in networking; thus simplifying network management and facilitating network security management[1]. in Software Engineering Conference (NSEC), 2014 National. The exponential growth of mobile devices and content, server virtualization and the introduction of cloud services are among the key computing trends which need new networking architecture. There's a massive need for software solutions that comprehensively address all areas of ESG not just the social side, according to IDC. This paper attempts to delineate the strengths and weaknesses of SDN. They pointed out that, although the Ethane architecture outlined a more detailed analysis on what SDN and openFlow would later become, International Journal of Scientific & Engineering Research, Volume 6, Issue 5, May-2015 1271. the architecture suffers from a number of major flaws; including but not limited to the fact that application traffic could comprise network policy.The introduction of a software extension called FortNox, to the openFlow controller provided an initial standard to measure SDN networks on the basis of their security performance [4]. Its designed to consolidate and deliver the networking components needed to support a fully virtualized infrastructure including virtual servers, storage, and even other networks. Recovery. An Efficient Defense Scheme against SIP DoS Attack in SDN Using Cloud SFW. Security in SDN means more than network visibility and microsegmentation, according to John Burke, analyst at Nemertes Research. The technique works more efficiently with known attack pattern, but is less popular with new and evolving attack patterns.d. ddos attacks igi

Conference rooms need to evolve as employees demand the same rich virtual meeting experience they have on desktop. Use the vector x (one-dimensional) to describe a network connection as follows: x = {xl, x2, , xn }, where xi , i = 1,2, . in Network Protocols (ICNP), 2013 21st IEEE International Conference on. If youre considering a network upgrade, dont let SDN security challenges impact the success of your deployment. [8] Mowla, N.I., D. Inshil, and C. Kijoon. A major strategy of DDOS attacks outlined by the authors is the use of program snippets called botnets, which are injected into a machine in the target network, from whence the attack is initiated.The OpenSecs innovative approach allows operators to customize the security of the network using human-readable policies and how the controller reacts automatically when malicious traffic is detected [10]. 2013. . The various vulnerability components and target elements of Klotis analysis are represented in table 1.0.As seen in the table 1.0 above, processes are most affected of all component types. Microsegmentation is another useful tool to maintain specific policies among workloads. The company already has a foothold Firewalls are an essential part of network security. They also analyzed the variations between SDNs and other domains with active trust research, describing why those differences were important as well as their implications.Adopting a somewhat divergent approach to their analysissome researchers [7], [11] , [24], [26] reasoned that the mostefficient algorithms that could proactively combat theprevalent resource attacks such as DOS and DDOS are thosethat are built into the core functionality of the OpenFlow system. When a device is lost or no longer needed for work purposes, a remote wipe can keep corporate data secure. Set up a time to talk about your technology. The core of SDN security concerns centers on the controller because anyone who has access to the controller can manipulate any aspect of the network. This technique involves search methods that provide approximate solution to an optimization problem. 2012 IEEE Network Operations and Management Symposium. Organizations can also benefit from evolving security capabilities, like enhanced monitoring, defined security zones and automated configuration. OSCO (Open Security-enhanced Compatible OpenFlow) platform is proposed, a unified, lightweight platform to enhance the security property and facilitate the security configuration and evaluation. Its all programmable by the end user, providing important benefits to the enterprise. [20] Beheshti, N. and Z. Ying. [22] addressed solutions for the open flow security and also proposed a comprehensive security architecture which enables security services like enforcing mandatory network policy correctly, to receive the network policy from the north bound API securely and to enhance the packet data scan detection to mitigate some attacks like worms. Neural networks: This is based on the techniques used by biological nervous system to process information. International Journal of Scientific & Engineering Research, Volume 6, Issue 5, May-2015 1270, Software Defined Networks Security: An Analysis of Issues and Solutions, Egbenimi Beredugo Eskca, Omar Abuzaghleh, Priya Joshi, Sandeep Bondugula, Takamasa Nakayama, Amreen Sultana. It is a scheme in which the security precedence level of the role inserting application decides, which role takes precedence over another.In analyzing SDN security, focus is primarily anchored on the Distributed denial of service and how it can be used to target SDN based networks. n, denote the i characteristic value, define Y = (+ 1,-1) (to represent normal or abnormal. Do Not Sell My Personal Info. Below is a sample demonstration of the Bayesian theorem.Given the values of attribute (a, a2, , an ) which describe the sample.Cmap = argmax C} E CP C} aI, a2 a)the expression can be rewritten using Bayesian theorem asCmap = argmax C} E C(aI, a2 an I C} )P(C} ) . As the second and third iterations of SD-WAN come around, we want to be part of that conversation in a meaningful way," Telstra America's Noah Drake said. 2014. Hasty deployment can plunge the organization into an insecure environment that's rampant with network vulnerabilities. Attack trees and graphs have been used by variousauthors [4], [5], [16] to model network security threats. Choosing the right software-driven network technology. OpenSec: A framework for, International Journal of Scientific & Engineering Research, Volume 6, Issue 5, May-2015 1275, implementing security policies using OpenFlow. This is a vital A remote wipe is a vital security tool as mobile devices become more common in the workplace. To clear some of the confusion, Nemertes' Burke said networking teams can use network analytics tools that provide useful visibility into network traffic. Contact usat Enterprise Visions to discuss strategies for securing your network with strategic planning before the upgrade is launched. Revisiting security aspects of Software-Defined Networking. If anything, the newer architecture requires networking teams to carefully consider the challenges and vulnerabilities, according to David Jacobs, principal at The Jacobs Group. The authors outlined twotypes of intrusion detection techniques.a. implementation taxonomy attacks in Future Networks and Services (SDN4FNS), 2013 IEEE SDN for. Their design was based on hybrid distributed system model. The paper then makes an analysis of previously outlined solutions to identifiable security issues of SDN. .. (1)Each of the p(C) is estimated simply by counting thefrequency of occurrence Cj of the target class in the trainingsample.f. DT is widely used in the areas of machine learning, data mining and statistics to solveclassification based problems. It is thus the opinion of this paper that a deliberate focus on security is essential if SDN is to take its place as the network architecture of the future. This method includes Self-Organizing Map (SOM) algorithm to classify network traffic as normal and abnormal. The SDN controller is the first point of focus for any network security strategy because a successful attack can disrupt or disable all network functions. Consequent upon these remarkable contributions is the requirement to deliberately isolate the functionality of the data plane from that of the control plane.
