Security News > 2020 > May > Security at the network edge: Inside software-defined networking and Kubernetes
Security concerns remain prominent across all network environments, with some unique to the network edge, SDN, and other services.
Securing subnets, switches, routers, and firewalls is a fairly traditional field, but security gets a lot tricker with such concepts as the network edge, software-defined networking and other newfangled services.
Scott Matteson: What security concerns are prevalent at the network edge, inside the SDN, and among services?
Bassam Khan: There are many recommended security measures to protect the network edge and SDN. These consist of encrypting the data, micro-segmenting the network to support the different types of applications, tunneling and access-control methods, and much more.
Kubernetes gives each pod in networking its own IP address, this allows for pods to communicate with one another without the use of NAT. In addition, Kubernetes allows for less complex networking as it shares machines between different applications and solves various problems throughout networking.
