Router Security: Ready for Primetime

I have a confession: I’m a technology late-adopter. On Rogers’ Innovation Adoption bell curve, I probably fall somewhere in the ‘late majority’ —  I like the tried and true.

But with a few years and many advances, I’m back on Facebook (my short experience with it left me with privacy paranoia),  and if you can believe it, I’m now an iPhone user. I appreciate not lugging around my iPod, and having a camera ready whenever I need it, but it’s not only the extra bells on the integrated device that has impressed me – it’s the realization that I don’t have to compromise functionality to have it all.

Another technology that has made a lot of strides since its entry into the market is integrated router security. Read More »

Three Pitfalls to Avoid While “Hitching your Wagon to the Cloud” (Pitfall 1: WAN Does Not Matter)

Last week at the Cloud Connect 2012 conference in Santa Clara, I was sharing a panel with industry colleagues representing the most prominent vendors in the application optimization, cloud infrastructure and network acceleration space . The topic was “hitching your wagon to the cloud”, discussing the importance of the network, particularly WAN, to make your cloud deployments successful. Folks talked about interesting concepts like “stateless branch office”, and “nirvana of Internet as WAN” before someone in the audience retorted, “I need solutions that help me deal with reality!” Read More »

Get Your Network Fit for Video – the Easy Way! AutoQos

The month of January always seems to be a very busy time at gyms; everyone resolves to starts the New Year off with good intentions. Now that February is here I can definitely see the trail-off  in attendance at the local gym. Have you resolved to deploy video this year, or have your users resolved for you? You’ll need to ensure your network is fit for the job. It won’t be difficult at all. There are features to make it easy to stay on track.

The first of those features is AutoQoS. The concept of AutoQoS is that the hard work of defining a QoS strategy and implementing it on the network is already done for you. Two main things compromise that strategy…

How Can I.T. Free Up Resources For New Projects with Cisco Catalyst SmartOperations?

This is the fourth and final blog in a series of campus switching innovation blogs that share our recent switching launch news from Cisco Live London.

How many times have you heard that IT cannot take on as many new projects as they would like to because their resources are tied up to keep the house running? That IT could do much more to drive business growth only if they had more resources?

We announced a number of innovations at Cisco Live London earlier this month, including Cisco Catalyst SmartOperations – a suite of about a dozen tools that offer built-in intelligence on Cisco Catalyst switches for easing many challenges faced by network administrators in their day-to-day tasks. And because most of the tools are included in the base software image, they deliver productivity savings without adding cost!

Block a Country with my Cisco Router or Firewall

Hi everyone. Starting this week, every Wednesday we are going to highlight a special security or wireless blog to round out our Borderless Networks theme. Today, we have a real treat for you with this security blog by Panos Kapanakis.  Here’s a nugget to pique your interest. Use the link to click through for more.


We are often asked by customers about how they can prevent traffic from a certain country (let’s say country X) from entering their network. The motivations for doing this could vary. Sometimes a company does not do business with all countries in the world; therefore, the company doesn’t need to be accessible from all countries. Other times it is an issue of trust and security, where an administrator may not want to allow country X to enter their infrastructure. Finally, there are cases where country X has often been incriminated with malicious activity, so an administrator may want to block country X when there is no need for the organization to interact with this country. In this document I present a methodology on how to write a tool that provides the configuration lines to block country X, using your IOS router or ASA/ASASM firewall.
