QOTW: Humility
Yet it remains true that general progress needs peace and co-operation, and that it is greatly hindered by pettiness of mind. In face of others’ superiority, there is only one honorable attitude: to be glad of it, and then it becomes our own joy, our own good fortune.

Three key challenges in vulnerability risk management
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
Vulnerability risk management has re-introduced itself as a top challenge – and priority – for even the most savvy IT organizations. Despite the best detection technologies, organizations continue to get compromised on a daily basis. Vulnerability scanning provides visibility into potential land mines across the network, but often just results in data tracked in spreadsheets and independent remediation teams scrambling in different directions.

Enterprise Networking Planet: With SDN, Programmability is the Point
By Arthur Cole
Software Defined Networking (SDN) is the moniker that the enterprise has accepted for the new breed of virtual network architectures abstracted from underlying hardware. But since software involves code, what we are really talking about is programmable networking. That raises a number of questions regarding the ultimate goal of this investment: programmed how? And programmed to do what, exactly? For specialty chip developers like Xilinx, a key function will be workload acceleration. As the enterprise tries to satisfy the twin masters of increased data volumes and demand for real-time data services, the need to quickly navigate through an ever-shifting set of network resources will become paramount.
Data Center Knowledge: Latency, Bandwidth, Disaster Recovery: Selecting the Right Data Center
By Bill Kleyman
In selecting the right type of data center colocation, administrators must thoroughly plan out their deployment and strategies. This means involving more than just facilities teams in the planning Continue reading
Telefónica Picks Juniper Over Alcatel-Lucent
A Wall Street analyst finds it "surprising" that Telefónica chose Juniper Networks edge routers, since the carrier had been an Alcatel-Lucent shop.
AWK and Cisco WLC
When you see an hacker movie you see people typing on the keyboard very fast. Actually the toughest the hacker is the faster he types very long commands and all of them work the first time. Want to impress friends…Unified Networking Lab for Alcatel-Lucent, Juniper, Cisco and many more…
A long time ago in a galaxy far, far away engineers hunted eBay for used routers to meet their demand for home labbing. Rack-rental services were kings and an ability to run cisco ios under dynamips felt like pure magic. Those dark days are gone… Thanks to massive eruption of virtualization technologies. In this topic I willUse nProbe and ELK Stack to Build a Netflow Solution on Software Gone Wild
How do you capture all the flows entering or exiting a data center if your core Nexus 7000 switch cannot do it in hardware? You take an x86 server, load nProbe on it, and connect the nProbe to an analysis system built with ELK stack… at least that’s what Clay Curtis did (and documented in a blog post).
Obviously I wanted to know more about his solution and invited him to the Software Gone Wild podcast. In Episode 39 we discussed:

Let me start this out by saying that I was thrilled to see Intel present at a NFD event! While Intel is well known in the network space for their NICs, they are most well known for their powerful line of processors, boards, and controllers. Most would argue that this doesn’t make them a ‘traditional’ network vendor but, as we all know, things are rapidly changing in the network space. As more and more network processing moves from hardware to software the Intel’s of the world will have an increasingly large role to play in the network market.
Check out the following presentations they gave at the recent NFD10 event…
Intel Open Network Platform Solutions for NFV
Intel Software Defined Infrastructure: Tips, Tricks and Tools for Network Design and Optimization
Here are some of my thoughts on the presentations that I thought were worth highlighting…
The impact of software and NFV
Intel made some interesting observations comparing telco companies using big hardware to Google using SDN and NFV. Most telco companies are still heavily reliant on big, high performance, hardware driven switches that can cost into the 10s of millions of dollars. Continue reading
Review: Rick and Morty
You might dismiss it, as on the surface it appears to be yet another edgy, poorly-drawn cartoon like The Simpsons or South Park. And in many ways, it is. But at the same time, hard sci-fi concepts infuse each episode. Sometimes, it's a parody of well-known sci-fi, such as shrinking a ship to voyage through a body. In other cases, it's wholly original sci-fi, such as creating a parallel "micro" universe whose inhabitants power your car battery. At least I think it's original. It might be based on some obscure sci-fi story I haven't read. Also, the car battery episode is vaguely similar to William Gibson's latest cyberpunk book "The Peripheral".
My point is this. It's got that offensive South Park quality that I love, but mostly, what I really like about the series is its hard sci-fi stories, and the way it either parodies or laughs at them. I know that in next year's "Mad Kitties" slate, I'm definitely going to write in Rick and Morty for a Hugo Award.

Five steps to optimize your firewall configuration
Firewalls are an essential part of network security, yet Gartner says 95% of all firewall breaches are caused by misconfiguration. In my work I come across many firewall configuration mistakes, most of which are easily avoidable. Here are five simple steps that can help you optimize your settings:
* Set specific policy configurations with minimum privilege. Firewalls are often installed with broad filtering policies, allowing traffic from any source to any destination. This is because the Network Operations team doesn’t know exactly what is needed so start with this broad rule and then work backwards. However, the reality is that, due to time pressures or simply not regarding it as a priority, they never get round to defining the firewall policies, leaving your network in this perpetually exposed state.

Why licensing wouldn’t work
Would you allow an unlicensed doctor to operate on you? Many argue that cybersecurity professionals, and even software programmers, should be licensed by the government similar to doctors. The above question is the basis for their argument.But this is bogus. The government isn't competent to judge doctors. It licenses a lot of bad doctors. It'll even give licenses to people who plainly aren't doctors. For example, in the state of Oregon, "naturopaths" (those practicing "natural", non-traditional medicine) can be licensed to be your primary care provider, prescribe medicines, and so on. Instead of guaranteeing "good" professionals, licensing gives an official seal of approval to "bad" practitioners. Naturopathy is, of course, complete nonsense, and Oregon politicians are a bunch of morons. (See the Portlandia series -- it's a documentary, not fiction).
Professions like licensing not because it improves the quality of the profession, but because it reduces competition. The steeper the licensing requirements, the more it keeps outsiders out. This allows the licensed to charge higher fees. This is why even bogus occupations like "hairdressers" seek licensing -- so they can charge more money.
Since different states license different occupations, we have nice experimental laboratory to measure Continue reading
