13Security-Driven Networking

LAURA DEANER

 

The digital world has changed around us as have the threats. But many organizations continue to operate with a mindset of legacy protection, believing themselves protected by perimeter firewalls. If we define the network only as a way to create the fastest routes, we give attackers a huge advantage. Security-driven networking is the broad idea that for cybersecurity to work properly, the network must be smarter and provide more inherent security.

Ultimately, security should be built deeply into a smarter, faster network. But that won't happen in the near term. In the meantime, cybersecurity professionals must take responsibility for advancing the implementation of security-driven networking. To move forward, we must determine how the network should be smarter and how that intelligence should be distributed across different parts of a more secure network.

In this chapter, we explain how the cloud has changed secure networking, discuss why last-generation solutions won't work, and outline the necessary steps CISOs must take to meet today's cybersecurity challenges and to build true security-driven networking.

The Cloud Has Changed Everything About Security

Over the last twenty years, organizations have moved from experimenting with one cloud to adopting multi-cloud to moving a majority of workloads to the cloud. In the meantime, people in a variety of professions are increasingly working remotely. Even when people are physically in ...
