The Third Generation of Security is Here
Organizations are rapidly adopting mobility, IoT, smart devices, and multi-cloud computing to meet new networking requirements. These changes are increasing the speed and the volume of the data and traffic that networks need to process. These network resources are also being constantly added, removed, or connected to each other, keeping the network’s attack surface constantly changing. The result is we are also creating complex networks that are difficult to track and secure.
Data and applications travel between many different users and devices, and span multiple borderless networks. This makes visibility and control more difficult. Cyber criminals are also targeting the expanded attack surface with faster and smarter cyber threats. Security needs to automatically adapt to changing network demands and configurations. Unfortunately, most legacy security systems simply can’t do this. Instead, organizations require a new generation of security designed to protect their hyperconnected, digital transformation networks.
The First and Second Generations of Security
The first generation of network security started 25 years ago. It was focused on securing network connections. Perimeter firewalls controlled who and what could connect to the network. Later, they were combined with VPN to...
