    ARIN runs out of IPv4 addresses by Scott Hogg

    After IANA allocated the final IPv4 addresses to the five Regional Internet Registries (RIRs) on February 3, 2011, the RIRs have been running out of IPv4 addresses over the past three years. APNIC ran out on April 15, 2011; RIPE NCC ran out on September 14, 2012; and now ARIN has run out on April 23, 2014. LACNIC will run out sometime this year, and AFRINIC may not run out for a couple of years. Now, organizations in Canada, the U.S., and some nearby islands will not be able to...

    Advanced Malware Detection and Response and Other Cybersecurity Services on the Rise by Jon Oltsik

     Think about all of the industry activity with malware detection and response and what comes to mind?  Most people would probably focus on technology vendors like Bromium, Cylance, Damballa, FireEye, and Palo Alto Networks since these firms have garnered headlines, raised vast fortunes of VC funding, and even pushed through successful IPOs. Yup, all of these technology vendors seem to be doing just fine, but there is another parallel success story in play - albeit a rather stealthy...

    Aerohive's new access points remove deployment barriers by Zeus Kerravala

    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.The primary driver of Wi-Fi is, of course, the influx of millions of consumer devices into the workplace, which means the wireless network needs...

    CISOs Must “Think Different” by Jon Oltsik

     Remember the "Think Different" advertising campaign from Apple?  It ran from 1997 to 2000 and featured bigger-than-life personalities like Buckminster Fuller, Martin Luther King, and Pablo Picasso.  The "Think Different" ads coincided with Steve Jobs's return to Apple and exemplify his somewhat contrarian and analytical mindset.  In a PBS interview, Jobs offered this philosophical insight about life: "The minute that you understand that you can poke life and actually...

    Cisco Live 2014: Dipping my Toes into the Social Side of Cisco Live by Denise Fishburne

    New to CiscoLive? At some point we all were there.  The mixture of emotions, of course, is different for everyone.  For me?  Crazy excitement coupled with a huge dose of adrenalin and fear.Why? Not only was Networkers 2006 going to be my first time ever going, I was going to be presenting.  So in 2006 I pretty much just stuck to doing the two things I love and adore the most: teach sessions and met with customers individually.  Other than that?  (smile)  I...

Cisco and Juniper have already confirmed that some of their products are affected, but Linksys - the home router company recently sold to Belkin by Cisco - says it products are fine.

    My Two Cents: Security, Market Implications of the End of Windows XP by Jon Oltsik

    I know there have been a substantial number of articles on the end of Windows XP and its implications, but I couldn't resist chiming in.  Hey, maybe I was destined to do so since I was one of a few thousand people at the Windows 95 introduction in Redmond (back in the summer of 1995 of course).  Here are my thoughts on this transition, I'll try to take a bit of a different angle on the topic.  1.  Microsoft will likely come out of this with a black eye.  Windows XP was...

    Managing IT Risk Associated with Mobile Computing Security by Jon Oltsik

    When BYOD was coming to fruition a few years ago, it had a sudden and deep impact on IT risk.  Why?  Many CISOs I spoke with at the time said it was purely a matter of scale.  All of a sudden, large enterprises had thousands of additional devices on their networks and they struggled to figure out what these devices were doing and how these activities impacted organizational risk. ESG recently published a new research report titled, The State of Mobile Computing Security, that...
