Next Generation Firewall vs. Container Firewall
What’s a Container Firewall? And how is it different than a Next Generation Firewall?
Containers and microservices are revolutionizing computing. But can firewalls help secure these? Next Generation Firewalls (NGFW) were supposed to handle the latest threats and data center designs, but fall short in the new cloud microservices environments. Here’s a comparison of the next generation firewall vs. container firewall.
Before we get into the features of a next generation firewall vs. container firewall, let’s take a look at the attributes of containers and microservices. Containers are part of a larger trend toward virtualized application workloads. Virtualized workloads, whether they are containers, IoT devices, or serverless computing provide a wealth of declarative meta-data from which security policies and decisions can be derived.
Attributes of Microservices – An Explosion of East-West TrafficThe migration from monolithic applications to container-based microservices brings many benefits but also changes communication patterns. The most significant change from a networking and security view is that there is now an explosion of East-West, or internal, traffic within hosts and between hosts. While each running container can be hardened and expose limited interfaces there are also many more opportunities for attackers to probe and find vulnerabilities.
