Information security of SDN on the basis of meta data

Abstract

Information security of SDN (Software Defined Network) is a part of support of information security in service-oriented architectures and clouds. These services can be presented in the form of tasks and the sets of subtasks and/or tasks represented by schedule diagrams of subtasks. Therefore it is necessary to consider the integrated information security system of such services. The model of security of cloud computing on the basis of interaction between level of tasks and level of SDN is constructed. It is shown that meta data about solvable tasks can be used for effective control of information flows at a network and can reduce the level of network threats. The constructed protocols allow different strength of a security.
