  • Summary: IoT Holds Great Promise – But Ensuring Its Security Takes Strong Leadership and Teamwork!

    Jeff Aboud
    18 Apr 2014 | 7:20 am
    Despite the many benefits of IoT, the billions of connected sensors, devices, and other smart objects it comprises will also dramatically increase the diversity of threats we will face. As a result, ensuring that we can reap the overwhelming benefits of IoT without undermining security will take strong leadership and a great deal of teamwork throughout the industry. That’s why I’m proud that Chris Young, Senior Vice President, Cisco Security Group, recently made the list as one of the top 100 thought leaders for IoT!

  • When and How to Use Cloud

    Bob Gault
    17 Apr 2014 | 5:30 am
    One thing is clear to me. Managing IT is similar to playing a game of Jenga, which challenges players to build a stack of blocks then remove those blocks without being the one to knock the whole stack over. Whenever an IT manager wants to make a move or a change to any of the technology stacks in the IT infrastructure, it’s literally like pulling out a block without knocking the entire stack over. For this reason, many companies are taking advantage of cloud computing to automate and simplify their IT management.

    17 Apr 2014 | 11:28 am
    Think of a modern enterprise data center.  There are likely hundreds of physical servers hosting thousands of VMs.  Individual systems are connected via 10gbE links that likely feed 40gb cores.  Local data centers connect over DWDM, remote data centers use MPLS, and cloud data centers chat amongst each other over high-speed VPNs.

    To say Wi-Fi is hot is as big an understatement as saying that A-Rod is a cheater. Everyone knows it’s true, but it’s bigger than most people think. In a joint ZK Research/Tech Target Network Purchase Intention Survey that was run near the end of 2013, Wi-Fi ranked as the No. 2 in priority for network managers, behind only the red-hot security market.
