Several security experts suggest that SDN (software-defined networking) is natively unsecure. They say it removes hardware boundaries, such as firewalls, that maintain security. They say SDN reveals new, unprotected surfaces to attack. These experts put forth a number of SDN vulnerabilities.
Perhaps those experts are thinking of a classic, yet immature SDN. "SDN has changed a lot in five years," says Vik Mehta, CEO, VastEdge, a software application services firm with an SDN practice. As we learn more about the technology, maybe we can agree that there are two sides to the SDN security coin.
As SDN ages, it increasingly secures itself using resources that become available as the technology blossoms. Consider how to apply a mix of common sense and SDN's strengths to intrinsically and dynamically protect the technology from within. Get started with today's SDN with state-of-the-art tools and approaches. See how SDN security done right holds up in the data protection prize ring.
Transition using proper steps
To securely get started using SDN, the enterprise must correctly get started using it. "SDN is a transition from a configurable to a programmable network," says Mehta. There are steps in that transition that the enterprise cannot ignore.
