We discussed the overall security approach for an enterprise in this chapter. We started with an overall view of the aspects of IT security and delved deep into securing the network. We discussed the security approaches for the network from a data plane, control plane, and management plane perspective. We ended the discussion with an overall view of securing the organization beyond the network devices.
In the next chapter, we will discuss the need to prioritize certain types of traffic over others, and the features and technologies to do this.
