I had the opportunity to present some of my research on the IT security skills shortage at last week's RSA Conference. This is a serious issue that doesn't get nearly enough attention.

| ||Breach! Defending Point of Sale Networks and Systems
Given the Point of Sale (PoS) attacks in the news lately I'm sure many of you are thinking about, or acting on, architecting better defenses. I recently worked with a team at Cisco to perform this same analysis on how to properly defend point-of-sale networks from attack. The attack scenarios we used were modeled after the recent breaches, blackpos and other PoS malware attacks.

| ||Final thoughts on the RSA Conference
The RSA Security conference 2014 has come and gone, and based on my experiences in San Francisco, it certainly appears we are in an "industrial revolution" as information security activity, innovation, and investment continue to grow. Early indications are that this was the biggest RSA Conference of all time.
Here are a few of my final thoughts on the show and the current state of cybersecurity:...

| ||So you want to adopt SDN: Where do you start?
Software Defined Networking (SDNs) has been the hottest topic in networking over the past few years, and will likely continue to be over the next couple. It’s certainly dominated the traffic on this site and others.

| ||RSA Conference recap: Positive direction for security industry
Last week's RSA Conference was a whirlwind of meetings, presentations, and unusual west coast rain storms. I'm not sure about the attendance numbers but it seemed especially busy - not surprising after the many cybersecurity events of 2013.
I met with around 40 different security vendors throughout the week and heard some encouraging news. Rather than crow about the latest technology fad or threat...

| ||Brocade's fabric strategy appears to be working
The networking industry has certainly gone ga-ga over the topic of software defined networks (SDN). Before SDNs were all the rage, network transformation had already begun with the use of fabrics. The rise of SDNs certainly took the media focus away from fabrics and that caused many vendors to shift their marketing messages as well.
However, one of the vendors that has been fairly consistent with the...

| ||2014: The year of IPv6
IPv6 is #1, #2, and #3 on my technical "to do list" for 2014. This is, for me, the year for IPv6.
Why IPv6 when there are so very many "exciting buzzward acronyms" out there right now? Because it is time.

Perhaps an indication of the tricky product transition it's going through, Cisco's share of the service provider router market slipped 5% in 2013 while Alcatel-Lucent and Juniper gained. Cisco's share slipped from 49% in Q1 to 44% in Q4 of 2013, according to Synergy Research Group.

In my blog yesterday, I outlined the hot topics I anticipate at this year's RSA Security Conference. Since the show is dominated by security vendors, the show hype will focus on products, services, and various technologies.

| ||Did Facebook overpay for WhatsApp?
This week, Facebook opened its wallet and shelled out a whopping $19 billion for WhatsApp. Most people think of WhatsApp as an over-the-top messaging application, but I think the company is much more than that.

| ||Hot Topics at the RSA Conference
It's the calm before the storm and I'm not talking about the unusual winter weather. Just a few days before the 2014 RSA Security Conference at the Moscone Center in San Francisco.
In spite of this year's controversy over the relationship between the NSA and RSA Security (the company), I expect a tremendous turnout that will likely shatter the attendance records of last year. Cybersecurity issues...

As new technologies continue to emerge in the network, the need for highly skilled IT administration resources will grow just as well.
However, the advent of Software Defined Networking (SDN), cloud systems, and orchestration software means many mundane tasks will become automated. If your day is mainly made up of those mundane tasks, then you should be worried about the future of your career. Read...

Cisco's earnings for the second quarter of fiscal 2014 were impacted by a $655 million charge to fix faulty memory components in a range of products. The buggy memory products were manunfactured by a single supplier between 2005 and 2010, Cisco said during its Q2 earnings conference call this week.

| ||Can the FIDO Alliance Help Obsolete User Name/Password Authentication?
It seems like yesterday when I was logging onto the VAX system at my alma mater UMass so I could work on a market research project with a statistics program. When my time slot came up, I would sit in front of a VT100 terminal, input my user name and password, and voila - a timesharing session at the cutting-edge of high tech.

Last month, VMware made a big splash in the Enterprise Mobile Management (EMM) market by plunking down over $1.5 billion for AirWatch. EMM, formerly known as mobile device management (MDM), has been one of the hottest market segments in tech, primarily due to the seemingly unstoppable force know as BYOD. This acquisition comes a little over a year after Citrix purchased Zenprise to complement its mobile...

The same three issues that plagued Cisco's Q1 impacted the company's second quarter as well: softness in emerging markets, order and revenue depression in service provider video, and new product transitions. This is despite the company actually beating Wall Street estimates in revenue and earnings per share.
