Relics of the Past: Why the Principle of Least Privilege Needs a Modern Rethink

By Brad Mandell

IT might live at the bleeding edge of innovation, but one of the fundamentals of modern IT security is still rooted in the early 1970s: the Principle of Least Privilege. When it was first introduced, the idea was that, to prevent breaches, every user should be given the minimal level of access to their organization’s IT infrastructure necessary to do their jobs. No more, no less. And, in theory, it made sense – limit the number of people who can reach your most sensitive data, and you limit your exposure to a breach. But, the Principle of Least Privilege was born at a time when the first floppy disks and microprocessors were barely off the assembly line. IT today is…

SDN and IoT Security

By Jay Turner

If we split IoT devices into 3 tiers, the highest would consist of well-protected devices, like laptops, that are complex machines with plenty of security software. The middle tier would be made of occasional use, moderate-complexity devices like thermostats, TVs, and refrigerators. Then we have the lowest tier.

SDN Security – Challenges, Benefits, and Strategies

As software-defined networking continues to increase in popularity as a flexible and dynamic approach to networking, it’s going to need a flexible and dynamic approach to security, as well. SDN forces security solutions to be proactive, protean, and responsive. 

CloudRouter 4.0 Slashes SDN App Development Time with FD.io

By Craig Oda

I’ve been working with IP networking gear for 25 years. In the early years, the new gear really got me excited. Although I’ve moved away from hands-on deployment, I’m still fascinated by the changes in the industry. The improvements in speed and bandwidth made things possible that were impossible before and have opened up a whole ranges of new business opportunities. Over the years, I became tired of hearing only about bigger and faster network gear. I largely lost interest until I heard about SDN. Unfortunately, the rate of SDN deployments wasn’t the tidal wave of change I had hoped for. Gear was often expensive and people really didn’t want to rip and replace their network architecture.

Channel(ing) the Future with Interconnection Ecosystems

By Chris Carr

SaaS companies, cloud service providers (CSPs), network service providers (NSPs) and data center providers (DCPs), by directly connecting with enterprises or facilitating those interconnections, can effectively make themselves into a channel between those enterprises and other customers.
