One of the great successes of software development in the last ten years has been the relatively decentralized approach to application development made available by containerization, allowing for rapid iteration, service-specific stacks, and (sometimes) elegant deployment and orchestration implementations that piece it all together.

The way to shrink it back to a manageable size is with effective network security solutions, which in their own right require an evolution from legacy security appliances to a secure access service edge (SASE) architecture.

A network attack is any attempt to gain access to or otherwise compromise the integrity or availability of a network. Network attacks come in many forms. Guaranteeing network security and performance in the face of these attacks, whatever form they take, is one of the principal responsibilities of network operators today.

These drivers, though, also come with baggage: the reassessment of todays corporate security model. Traditionally, Wide Area Networks (WANs) and network security were loosely coupled entities.

Since the beginning of networks, the lynchpin of network security has been the firewall.
