Networking blogs: The evolution of network access control

In this week's blog roundup, get an expert's insights on Cisco's unique approach to SDN, and find out why EMC thinks EVAS has bright future.

Goodbye NAC, Hello EVAS

Network access control (NAC) was introduced in 2004 to combat Internet worms that were capable of infecting entire

corporate networks. But around 2008, NAC seemed to fizzle out due to vendor exhaustion and new technologies. ESG, however, believes that NAC has evolved and that it deserves a new categorization -- endpoint visibility, access and security, or EVAS.

Read now to learn why ESG believes that the cloud, modern security requirements and the "Internet of everything" will make EVAS a $700 million market by 2017.

DNS server naming unconventions

When it comes to device names, adding something that lets you know where it's physically located and/or which type of server it is can be helpful during troubleshooting. But does this also pose a security risk? And what might be some better naming conventions for a domain name server?

Read now for Tom Hollingsworth's take on the safest DNS server naming conventions.

Cisco's answer to SDN

Cisco ONE, Cisco's response to software-defined networking and network programmability, is a unique view of SDN, provided through a series of application programming interfaces, controllers and plug-ins. Cisco has stopped short of completely separating the data plane and control panel. Rather, they've rolled out a framework to address the desire for a more programmable networking layer while protecting intelligence within the delivery plane. Tracy Corbo just spent a week at C-scape and has some key takeaways about Cisco, SDN and Cisco ONE.
