Using WPA2 to avoid data breach headlines
When most people hear “data breach” they think about lost laptops, server break-ins, or malware-based attacks. But according to a new survey by Spiceworks, commissioned by Certes Networks, lax network security and traffic segmentation played a crucial role in data breaches reported in 2013-2014. A few of this survey’s top findings included:
* Encryption for data in motion is highly fragmented, with 3 out of 4 companies using at least two methods – most often SSL-protected web traffic, followed by SSL-based VPNs.
Three of the Top 11 Network Troubleshooting Tips
Guest writing for our blog this week is Tony Fortunato, a senior network performance specialist with The Technology Firm. Tony has more than 20 years’ experience working with network pros on designing, implementing and troubleshooting networks, and he has some recommendations for more effective troubleshooting.
Why is End User Response Time so Important to Measure?
When Network Performance Management Systems started out, they largely depended on SNMP and active ping testing to monitor infrastructure uptime and performance.
Real-Time Live Network Data Boosts Performance
In a world of daredevils and high stakes, being “on a wire” is to be in a constant state of danger where one mistake could be fatal. For those concerned about network management and application performance, being on a wire means coming up with a way to analyze and take action from data - the solid base of all effective network visibility and management.
Network Capacity Planning with the Visual TruView
This week on LoveMyTool, Fluke Networks presented a LMTV session focusing on the Network Capacity Planning features of TruView. In the video, we discuss the challenges network engineers face when performing Capacity Planning, if it is done at all, and why this step is so critical in advance of upgrading key links or WAN connections. The Capacity Planning features of TruView are discussed in detail, which give unprecedented visibility to engineers who are considering whether an upgrade is necessary or not.

Tech Buyers say Fluke Networks Visual TruView Provides Visibility for Improving Network and App Performance
Guest writing on our blog this week is Ariel Lindenfeld, director of Community Management at IT Central Station, a leading product review site for enterprise technology buyers. IT Central Station provides a platform that offers product information from real users that is current, objective, and relevant.
Think Before You Upgrade: Will More Bandwidth Really Help?
Upgrading network connections to higher bandwidth can bring some false hopes.
Say ‘Good-bye’ to Data Traffic Jams and ‘Hello’ to Satisfied Customers with Network Time Machine LTE/VoLTE
The age of mobility has arrived, but the mobility wave has hardly begun to form, much less crest. In the last few years, the volume of voice, data, and video communications flowing over carrier wireless networks has sharply risen. In parallel, subscribers expect superior, consistent quality of service regardless of network utilization or their location – whether they are on the move or within a building.
The Ongoing Challenge of Managing VoIP
Every year, I survey a couple hundred IT professionals on a variety of topics, including what their organization wants to improve on over the next year. It is not at all surprising that the task that is typically at the top of the list is rapidly identifying the root cause of degraded application performance.
The Importance of Flow Based Monitoring
The 2013 Application and Service Delivery Handbook1 contained the results of a survey that I gave to roughly 200 IT professionals.
Interpreting the Tool: What Does Poor Network Performance Look Like?
A hammer is a fantastic tool with a million uses. A skilled builder can use it to frame a house, put up a roof, or repair a wall. But the hammer itself doesn’t have skill – that depends on the person using it.
In a similar way, network analysis tools have a million uses. They can help get to the root cause of nagging application performance problems and network problems.
What’s Happening with Server Virtualization and Data Center Consolidation?
Ok, I admit it. Like a lot of analysts I get attracted to the shiny new object, whether that new object is SDN, Big Data or software defined data centers. Shiny new objects like SDN are fun to learn about and given the breadth of approaches that are becoming available in the marketplace, fun to write about. The problem with shiny new objects like SDN, however, is that it will be at least a couple of years before the vast majority of enterprise IT organizations have a significant production deployment of them. So, wh
Take Off the Application and Network Performance Blinders with Newly Integrated Visual TruView and OptiView XG
Today’s IT has increasingly shifted toward application-centric, service-oriented operations, and the need for application awareness within performance monitoring and management technologies has skyrocketed as a result. End-user expectations have also risen sharply in line with their use of smart devices, mobile applications and streaming media. While end users may blame “the network” for any difficulties they encounter, the actual problem may reside elsewhere.
Fluke Networks’ AANPM Vision Realized with Gartner’s New NPMD Magic Quadrant
Back in February, I discussed what it's been like to break ground in the emerging application-aware network performance (AANPM) market. The report referenced Gartner’s plans to release its first-ever network performance monitoring and diagnostics (NPMD) Magic Quadrant to include AANPM solutions.
What Management Questions Should you Ask your Vendors?
If your role is to manage IT applications and services, the challenges you face must be causing your head to spin. For example, managing pesky legacy applications and infrastructure components can be time consuming and stressful. At the same time however, IT professionals are facing an array of new management challenges brought on by the adoption of mobility, virtualization, cloud computing and software defined data centers, storage and networking.
Vision realized: AANPM and NPMD hit the mainstream
For innovators, there are times when being out ahead of the market requires an extra helping of self-confidence. As you wait for the rest of the industry to catch up, you have to smile patiently and explain to those who don’t get what you’re doing why it’s different, how it’s better and why, ultimately, you’re on the right course… usually more than once.
The DevOps Opportunity
For as long as I can remember IT organizations have been told that they have to become more agile in order to keep up with the rapid pace of business change. The good news is that over the last several years IT has become more agile. The bad news is that over the last several years, the pace of business change has also increased. The rapid pace of business change was driven home in a recent report authored by two MIT researchers1 .
Managing an SDN: Something Old, Something New
For the last eighteen months SDN has been the hottest topic in networking. It’s clearly impossible to state with certainty exactly how SDN will evolve. However, there is significant momentum behind some of key tenants of SDN including an increased reliance on software, the centralization of at least some control functionality and the increased use of automation.
Why are Monitoring and Analysis Tools Still Considered "Optional"?
"We just can't free up the budget"
Those words seem to be heard more often by vendors in the monitoring and analysis space of IT. They aren’t new words either. Over the past few decades, when budgets are considered for IT, precious dollars are preserved for infrastructure upgrades, server platforms, end user gear, and a host of necessary services. That’s not a bad thing at all, those are critical things to spend money on.
Wired and Wireless Analysis: Troubleshooting on Both Sides of the Access Point
In today’s business environment, it’s not hard to imagine that the average corporate user has anywhere from two to four mobile devices that access a network. In the past, wireless users have only needed email and Internet access for their mobile devices, which require relatively low bandwidth.
