The BYOD Security Dilemma
The Information Security Forum this week released a report titled 'Threat Horizon 2014' that looks at the continued global threat to computer networks, businesses and individuals from cybercrime. But one section of the report also looks at 'Internal Threats', which at first glance would seem like another discussion about malicious insiders who attack the network because they’re disgruntled. In fact, the Internal Threats identified in this report are from new technology that comes into an o
5 Secure Switch Management Best Practices
One of the easiest things an organization can do to help increase the security posture of their infrastructure is to implement a policy and standard for secure management. Often overlooked, or not fully executed, this is what I consider to be the low hanging fruit of network security.
Data Caps And Treating Employees Like Adults
Carriers like AT&T and Verizon Wireless are using data caps to manage the explosive growth in 3G/4G data consumption. Hey, kids--the 1990s called and wants its bandwidth management strategy back. As Lee Badman points out in "4G? No, It's More Like 4Gee!" the data rates available to wireless consumers are growing rapidly and our demand is keeping pace. When you have high demand and data caps, the chance of overages is very likely, and the last thing anyone wants is out-of-control telecom costs. C
HP-Polycom Partnership May Boost Lync Adoption
HP and Polycom are taking their partnership to a new level, combining HP’s networking technology and Polycom’s videoconferencing products to deliver Microsoft’s Lync unified communications platform to the enterprise. An HP representative says that while many Lync licenses have been sold by Microsoft, several of those deployments are on hold because of the complexity of integrating the three elements--complexity that the two partners aim to address.
Zero to Private Cloud in 8 Steps
Here are eight steps for going from zero to private cloud. Note that I didn’t say eight "easy" steps. But don’t let that bother you--nothing that’s easy is ever worth doing anyway.
Arista Outpaces Cisco Again With FPGA Switch
Applications and initiatives like private cloud computing, virtualization and mobility are placing increasing pressure on network infrastructure to be faster and more capable. Initiatives like software-defined networking and protocols such as OpenFlow can make the network more flexible and manageable, but they don’t really solve the problem of application performance where high-speed, low-latency requirements are the rule. Only by removing hops and their attendant latency from the network
Is Your Network Ready For Romley?
Server manufacturers have been quick to roll out new models designed to run on Intel’s new Xeon E5 family of processors, a.k.a. Romley, which touts an 80% performance improvement over earlier Xeon versions. As surely as the knee bone’s connected to the thigh bone, a boost in server performance is going to demand a bigger network pipeline. Networking vendors and other industry experts think the introduction of Romley is going to be a significant catalyst for adoption of 10-Gigabit Eth
4G? No, It’s More Like 4Gee!
Have you actually held a 4G device in your hands while it does a speed test? Has your brain struggled to reconcile the numbers displayed at the end of the test with the fact that you’re connected to a mobile network and not Wi-Fi? Have you felt your reality get pleasantly rocked in a way that left you a bit confounded over the numbers that your device was showing you? This 4G stuff is simply amazing.

Networking In The Cloud
In discussing network design with my clients, I talk about how routers, firewalls and other network gear can be interconnected to provide a scalable and redundant IP network. These foundations of network design apply to networks composed of tangible components or the virtualized infrastructure that extends corporate data centers to the cloud. I find that the networking aspects of cloud computing are frequently overlooked or addressed as an afterthought.
The Security Profession Is A Mess
I've been considering how to build a network security plan for a small data center with an online presence. To put the proposal together I needed to develop some sort of structure in the security space so that I could research products and vendors. What I found is that implementing firewalls and IDSes is simple. Finding competent security professionals is not.

Next-Gen Networking Drives IT Budgets
Vice President Joe Biden once said, "Don't tell me your values, show me your budget and I'll tell you your values." If the vice president saw the enterprise IT spending budgets, he would rightly conclude that they place an increasingly higher value on their networks as the critical circulation system for all of their IT assets. As demands are placed on networks to handle more video traffic, migrate to 10GbE connectivity, connect mobile and wireless devices, and handle the increase in data traffi
WOCs Address Soaring Bandwidth Demand
