Threats as spoofing, tampering, information disclosure, Denial of Service, flow table overloading, and so on have been addressed by many researchers. In this paper, we present novel SDN design to solve three security threats: flow table overloading is solved by constructing a star topology-based architecture, unsupervised hashing method mitigates link spoofing attack, and fuzzy classifier combined with L1-ELM running on a neural network for isolating anomaly packets from normal packets. For effective flow migration Discrete-Time Finite-State Markov Chain model is applied. Extensive simulations using OMNeT++ demonstrate the performance of our proposed approach, which is better at preserving holding time than are other state-of-the-art works from the literature.<\/jats:p>","DOI":"10.1155\/2018\/1308678","type":"journal-article","created":{"date-parts":[[2018,2,19]],"date-time":"2018-02-19T18:31:29Z","timestamp":1519065089000},"page":"1-14","source":"Crossref","is-referenced-by-count":9,"title":["Validating User Flows to Protect Software Defined Network Environments"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0727-0487","authenticated-orcid":true,"given":"Ihsan H.","family":"Abdulqadder","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]},{"given":"Deqing","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"},{"name":"Shenzhen Huazhong University of Science and Technology Research Institute, Shenzhen 518057, China"}]},{"given":"Israa T.","family":"Aziz","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"},{"name":"University of Mosul, Mosul 41002, Iraq"}]},{"given":"Bin","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]}],"member":"311","reference":[{"key":"1","first-page":"96","volume":"15","year":"2017","journal-title":"IEEE Security & Privacy"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2016.2618874"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1002\/sec.1737"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2017.03.004"},{"issue":"99","key":"5","year":"2016","journal-title":"IEEE Transactions on Services Computing"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1049\/el.2016.2234"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2017.2666270"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TNET.2016.2626287"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2015.02.026"},{"key":"14","doi-asserted-by":"crossref","first-page":"634","DOI":"10.1631\/FITEE.1500321","volume":"17","year":"2016","journal-title":"Frontiers of Information Technology & Electronic Engineering"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/TCC.2014.2355227"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2016.03.005"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2016.12.024"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2015.2474118"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1002\/sec.1759"},{"issue":"3","key":"24","volume":"19","year":"2017","journal-title":"IEEE Communications Surveys &Tutorials"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2016.2638430"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.3837\/tiis.2017.04.020"},{"key":"31","doi-asserted-by":"publisher","DOI":"10.3837\/tiis.2016.09.027"},{"key":"33","doi-asserted-by":"publisher","DOI":"10.3837\/tiis.2017.02.012"},{"key":"36","doi-asserted-by":"publisher","DOI":"10.1109\/TNSM.2016.2517407"},{"key":"37","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2015.2469138"},{"key":"38","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2014.04.073"}],"container-title":["Security and Communication Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2018\/1308678.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2018\/1308678.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2018\/1308678.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,10,11]],"date-time":"2019-10-11T01:16:45Z","timestamp":1570756605000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/scn\/2018\/1308678\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":23,"alternative-id":["1308678","1308678"],"URL":"https:\/\/doi.org\/10.1155\/2018\/1308678","relation":{},"ISSN":["1939-0114","1939-0122"],"issn-type":[{"value":"1939-0114","type":"print"},{"value":"1939-0122","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018]]}}}
