Detection as a service: An SDN application

  • Kantola R.
  • Khatri V.
  • Monshizadeh M.

In a cloud computing environment, future networks will most probably utilize network functions virtualization (NFV) which is a network architecture concept that proposes virtualizing network node functions into “building blocks” or entities that may be operationally connected or linked together to provide services. However, applying these mechanisms brings security challenges. ...
