  Networking Nuggets and Security Snippets

  The China Syndrome by Jon Oltsik

  Chinese hacking exploits became mainstream news over the past few months leading up to last week’s meeting between U.S. President Obama and Chinese President Xi Jinping. While cybersecurity was a primary topic however, there was no breakthrough deal coming out of the tete-a-tete. The two countries did agree to work together on cybersecurity issues in the future. With no concrete progress, China is bound to remain a poster child as a cyber adversary here in the U.S.A but those of us who...

  Every Network Failure Should Be Used to Improve the Network by Denise Fishburne

  Let's accept reality. A network is so much more than just the sum of its electronic parts, operating systems, and configurations. It is an extension of the past and the present of our company. Much like the growth rings of a tree, we can look at our company's network and see all the human history of our company.  That is probably why post-mortems are so hard and completely avoided or unproductive. People often bring much "baggage"  to the post-mortem. Agendas, politics,...

  Cisco looks to standardize context-aware security by Jim Duffy

  Cisco is looking to standardize a framework it developed for integrating disparate security products from multiple vendors.

ISE is designed to provide policy-based, context-aware security for Cisco networks.By developing to pxGrid, third-parties will be able to add capabilities to ISE that allow the appliance to...

  Why Aren’t We Questioning the Effectiveness of the NSA Program? by Jon Oltsik

  Full disclosure, I am extremely uncomfortable with the intrusive intelligence programs going on at NSA. If it weren’t for Edward Snowden and Mark Klein (former AT&T technician) we wouldn’t know about NSA activities on telephony and data networks. It makes you wonder what additional data the NSA is collecting that we don’t know about. Beyond the privacy issue however, there are a few other fundamental questions here and I don’t hear anyone asking them. Allow me to chime in: 1. How...

  Next-generation Enterprise WANs

  The cloud is enabling the Next-generation Enterprise WAN, and vice versa by Andy Gottlieb

  Having spent the last several columns looking in depth into why MPLS is no longer the only answer for building enterprise WANs, this time let's go up a few thousand feet and look at the bigger picture, before any further dives down into the details. "The cloud" is happening. We'll leave aside for the moment exactly what "the cloud" means, as it tends to mean different things to different people, but I think readers here have at least a "kinda sorta" understanding of what it is. As it relates to...

  Mobile vs. Portable and the changing nature of the office by Zeus Kerravala

  The vision of being able to deliver any content or application to any device no matter where a worker is located has eluded IT for over a decade now. The desire to get there is great as it promises to change the way people work and raise the productivity level of employees no matter where they may be. Any inability to fulfill this “any” vision certainly shouldn’t be looked at as reflection of IT. It’s more that the technology didn’t really exist to enable a truly fluid, mobile work...
