Security is an ever-evolving concept in theory and application. It is important to deploy and leverage technologies that can adapt and change with our security models. In the technology world, when the networking and application protocols were initially developed, minimal thought was given to security. Protocols like Telnet, FTP, DNS, SMTP, and even HTTP were designed for function and user-experience, not integrity.
Network architectures are changing with the evolution of software-defined technologies, cloud, and virtualization. Meanwhile, applications and the data they are delivering are morphing to be specific, individualized, and timely.
