IT futurists have long predicted the eventual disappearance of the so-called perimeter, but the truth is that physical networks — and the solutions for securing them — are far from their last days.
And while the cloud has heralded the arrival of infrastructure-as-a-service (IaaS) and software-defined networks (SDN), at the end of the day, these services are delivered out of physical data centers, albeit distributed and dispersed across the globe. For traditional firms with on-premises IT infrastructures, network security continues to increase in complexity in order to keep up with ever-sophisticated cyber attackers.
Whether on premises or in the cloud, IT infrastructures are prone to the same security issues and are equally exposed to cyber threats. However, with today’s networks supporting a vastly greater number of users, devices, and Internet of Things (IoT) sensors, the enterprise attack surface’s composition has evolved significantly even when compared to just a few years ago.
Network Security Today
Today’s network security offerings range from traditional intrusion detection and prevention systems (IDPS) to next-generation firewalls (NGFW) and unified threat…
