    Enterprises Need Outside-In Continuous Monitoring for Risk Management by Jon Oltsik

    Ask any CISO what their job entails and they are likely to respond with a common mantra:  Assess IT risk, communicate IT risk to business executives, and then create and execute a mutually agreed upon plan to address risk.  In the past, CISOs concentrated this effort on internal IT but this internal focus is becoming increasingly myopic because: 1.  Outsiders have network access.  Enterprises regularly grant network access to business partners, suppliers, and...

    How F5 Networks countered the Heartbleed bug by Zeus Kerravala

    Over the last few weeks, the security industry has been rocked by the Heartbleed bug, which impacted OpenSSL-based websites. Heartbleed takes advantage of an OpenSSL feature called heartbeat, which exchanges data between the user’s computer and the webserver. Heartbleed causes the web server to send back a massive amount of data, rather than only the data it’s supposed to, including sensitive, private customer information. The bug caused many companies and vendors to scramble to develop a fix...

    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.

    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...
