Normally I don’t get too excited about the idea of having video tutorials about how to use a web site. I mean, web sites should be “easy and intuitive,” right?But in truth, there are sometimes complicated functions on a site that require explanation and demo.Here’s a really nice example of video demonstration from Colin McNamara, who has put together a short demo for partners of how to use the Online Interactive Configurator.Enjoy!
This Cisco Live in Second Life TechChat featured Shelly Cadora, PhD, and Ken Hook, technical marketing engineer, for Identity-Based Networking solutions at Cisco. During this TechChat, Cadora and Hook discussed how Cisco’s Identity-Based Networking Services (IBNS) help businesses by providing an innovative, scalable, and flexible solution to manage identity; the foundation for securing your network and business resources.View this online discussion to hear how IBNS:- Helps you understand and control who is on your network- Reduces overall investment by enabling identity of legacy hardware- Enables cost-effective management of changes throughout the organization- Is a scalable and more flexible identity solution, making it easier to deployClick play below to view the archive.We need your feedback.

If you’ve ever managed a web project, you know how vexing it can be to get started with a clear scope and direction, especially if a redesign is part of the agenda. Maybe you’ve worked on a web project in the past where some important starting criteria wasn’t identified early, or the team forgot to define some specific items like success objectives, or calls to action, or desired metrics or customer needs. When this happens, this definition gap causes resets and rework. Worse, if you were working with an outside web design vendor, this rework and redefinition probably slowed down the project, degraded final quality, and added to the final cost of design and delivery. So, it’s important to get projects started on the right track. We do so at Cisco by way of a magical document called a Web Design Brief. I thought you might be interested in the format we use, and may find it useful in your own organization. So, you can download our Web Design Brief template here. The idea of the Design Brief is simple: (1) Answer some key project questions in a friendly PowerPoint format, and then (2) share it with your web team and designers or (if the project is big) prospective design vendors. It’s an easy and effective way of figuring out what you’re really trying to do with a new design or section revamp.A design brief will save you time, aggravation, and money, by answering fundamental questions such as:
- Why are you embarking on this new web project, anyway?
- What are your primary business objectives and success measures?
- Who are you audiences and what are your users key requirements?
- What similar sites or projects inspire you?
- What kinds of customer data and site metrics do you have available to inform the design?
- Who are the key contacts and stakeholders, and what other related projects are underway?
- What is the global reach of the project?
- The objectives of the project are clear, so projects get kicked more efficiently with our design resources, saving time and money
- The projects get completed more predictably, since there are fewer restarts and resets
- Considerations like metrics plans and global deployment aren’t surprises, since they’re flagged up front
- Design estimates with vendors tend to be better, since the project is well defined
This is part III in the series of technical foundation posts leading up to our December 11 TechChat“Networks That Know You: Cisco Identity-Based Networking Services”.
Have you ever left the house and forgotten to lock the front door? It can ruin your day, especially if you remember it as you’re pulling up to the office after a grueling commute. But maybe, being a security geek, you’ve installed a security web-cam over the front door. So you fire up your browser and monitor the house. You may not be able to lock the door remotely, but you can at least see if anyone tries to break in.Authenticating someone’s identity without enforcing some form of authorization is like having an unlocked door with a web-cam: you can’t physically prevent anyone from gaining access, but you can see who goes in and out. This kind of visibility is a non-trivial asset. Knowing that someone is watching may be enough to deter some intruders. Still, authentication (the web-cam) by itself may not be an adequate long-term security policy for most homeowners. The same goes for networks. Once you’ve authenticated endpoints and users with IEEE 802.1X or MAC-Authentication Bypass (MAB), it’s time to enforce network access restrictions based on the established identity of that user or endpoint. The rest of this blog looks at the different forms of authorization in Identity-Based Networking Services (IBNS) today.Default Authorization: The default authorization in an 802.1X-enabled network is binary: on or off. All endpoints and users that pass authentication get full access to the statically configured VLAN on the port. Those that can’t authenticate get no access. This is how 802.1X was originally designed to work. However, this default authorization policy may be too black-and-white for real world networks. In the real world, giving every authenticated user and device the same level of access in the statically configured VLAN may not offer enough granularity to meet the goals of your security policy. In addition, you may have good reasons to offer limited access to users who can’t authenticate. Other forms of authorization can be used to accomplish these goals.Dynamic Authorization: Instead of putting all authenticated users into the same static VLAN, some corporations need to be able to grant differentiated access, where one group of known users (“œEngineering”) gets access to different network resources than another (“œFinance”). Dynamic VLAN assignment is a form of dynamic authorization where the AAA server (the centralized security policy server) tells the switch to assign a VLAN to the port based on the identity of the user or device that authenticated. Engineers go in the Engineering VLAN, accountants go in the Finance VLAN. While this form of dynamic authorization is a powerful tool for differentiating access for different user groups, it comes at a cost. Supporting multiple VLANs on every switch may require changes to the network architecture and addressing scheme. In addition, VLANs isolate traffic at Layer 2 in the OSI stack so dynamic VLAN assignment by itself cannot restrict access to specific subnets (at Layer 3) or applications (Layer 4 and above). However, dynamic VLAN assignment does provide the foundation for virtualizing IT resources using Network Virtualization Solutions. Get more information on how Network Virtualization can increase security with path isolation and virtualized services. Local Authorization: With local authorization configured, the switch can allow access to the port in special VLANs in the absence of a successful authentication: endpoints that are not 802.1X capable can be assigned to the Guest VLAN; endpoints that fail 802.1X can be assigned to the Auth-Fail VLAN, endpoints that can’t authenticate because the AAA server is unavailable can be assigned to the Critical-Auth VLAN. With local authorization, endpoints that would otherwise be denied network access entirely can get some form of access. Different networks need different kinds of authorization policies. Many large customers have successfully deployed 802.1X and IBNS on wired networks using the techniques I described above. But other customers still find it challenging to deploy 802.1X. In our Second Life TechChat next week, we’ll talk about new and upcoming innovations in all three kinds of authorizations -default, dynamic and local -that will make IBNS simpler to deploy and easier to customize.Written by Shelly Cadora, PhD**Shelly will be one of our speakers during the December Cisco Live in Second Life TechChat.

Human social and technological transformations are forming on a tectonic scale creating new advancements and opportunity. New ideas and tools are being created, to help understand and raise the standard of living for the undeveloped and developed world around us. Whether from social, economic, informational, manufacturing, distribution processes and consumer behavior, there increasingly determined by the intricate dynamics of these evolving networks or simply said, the coming ‘ Internet of Things‘. Allow me to attempt to connect a few dots Bruce Sterling, Author and Futurist of,”Shaping Things“, best describes the phenomena of ‘Spimes’. Sterling coined the name ‘Spime’ by contracting the words ‘space’ and ‘time’. Spimes have the ability to be aware of their environment, they know where they are, and when they are, and keep track of some parameter around them. Sensing, memory, and ubiquitous communication enable Spimes to accurately map the physical world around them. He describes that we have come from the making of artifacts from hand to complex machines and the recent era of ‘gizmos’. Those methods of using finite materials and energy have reached beyond unreasonable levels becoming economically unsustainable and toxic on many levels. FlickrWatch this very interesting Bruce Sterling interview Part 1, Part 2, Part 3. The ‘Spime’ represents the new form of object that can be formed. They are here already in their most primitive form on our phones and laptops. Future objects or Spimes will be so informational rich and extensive they will be regarded as a new form of material in an immaterial system. Spimes basically rely on improvements in distribution chain management technology (such as computationally active - not passive - RFID chips with GPS positioning and time-binding capability) to monitor their own progress, order supplies and maintenance work, notify their owner when action is required, and, at the end of their life, arrange for their own collection and dispatch to a suitable recycling point.This past Spring David Orban Chief Evangelist at Widetag.com The OpenSpime Technology Company, spoke about their project the world of OpenSpime at ETech He asked,”Do we really know our planet? Because it talks to us but it talks to us in a manner we can not comprehend quickly enough because our societies change the planet more quickly than we can listen”. He believes that OpenSpime will give us the tools to listen and monitor our planet; further more giving us the ability to have pier to pier Science to collectively explore new ideas and creativity. More recently this month at Shift 08 he goes beyond the surface and describes not why but how you can manage to filter and aggregate critical data as it’s generated from tens of millions of sensor devices. FlickrEteh Watch here Shift 08 Watch hereLater on this past summer the OpenSpime Developer Network and OpenSpime.org were launched. The architecture of the OpenSpime protocols, based on an extension to XMPP, formally known as Jabber, is available for anyone to explore, and improve. Anybody can run his or her own OpenSpime servers, and implement OpenSpime compliant applications using the Pyopenspime libraries which were released simultaneously.Technical explanation watch here.Tagging to Fabbing The wisdom of crowd sourcing is already at work with a cool mashup using OpenSpime and Google Maps to detect CO2 gases.

Push a little more to stream live broadcast from YouTube or Flickr galleries, Twitter feeds, sub-group match making for breakouts and background statistics in 3D graphics from different points around the world playing along the surrounding walls? The clouds in the sky, time of day, ambient lighting, music and audio translation could all be altered live individually per screen. The effective reduction in the size of the combined carbon foot print not only achieving significant cost savings but is extremely information rich experience accelerates the connected network effect. Ultimately shaping the design of such experiences would reflect positively on the entities brand perception. Current efforts by EOLUS in Second Life have brought together several companies to collaborate on creative solutions that demonstrate mixing real and virtual life ecommerce integrated with real world supply chain and CRM. Spimes are the logical output of a logistics infrastructure based on now affordable fabbers such as the Mcor Matrix, The only 3D printer in the world that can use ordinary/used A4 paper to make 3D objects at costs up to 50 times less expensive than its competitors’ current technologies. Ponoko.com allows you to design a product and get it made in your own personal factory. You can also edit and mashup the product plans you download from Ponoko to create something completely original. If that isn’t enough you can produce and sell real homemade toys right from Second Life by creating plastic versions of avatars with Fabjectory.com Designing the Shape of Things has a profound effect on our quality of life. The motivation for companies to pay greater attention how they effect the ‘human experience’ in part can be viewed from areas of technological stagnation. A current example is with auto manufacturers who have been up against competition using better technology who have the upper hand on quality and price. Introducing Spimes could help the former change their thinking of designing for categories of products into experiences designed for an intended purpose. The more aware of experiences that your customers having or not with objects the better you can fine tune your offering. Designing for the ‘Shape of Things’, presents a robust offering of technologies to inspire marketers and provoke innovators into rethinking their market offerings’ essential qualities.I hope to expand on this more next time-Until then. : ) Dennis
