Using Microsegmentation to Prevent Security Breaches

No one likes to admit it but most of what has passed for IT security in the enterprise has historically been rudimentary at best. Most organizations physically segmented their networks behind a series of firewalls deployed at the edge of the network. The trouble is that once malware gets past the...

The Quest for Container Networking Interoperability

It’s now apparent to most savvy IT professionals that microservices enabled by containers need to be joined at the proverbial hip to the ability to create microsegments using network virtualization (NV) software. Just how that’s going to happen is still a matter of debate. VMware, for example, is...

Introducing the new superheroes of the networking world...no, not me!

SDN and NFV may look like the new superheroes of the networking world, but they are only foundation members of an orchestra now playing a dynamic network symphony. Hybrid WAN's are one thing, but software defined or "SD-WAN's" are another. The key difference in my opinion; centralised control...
