Strong Encryption Is Essential to Our Security, Not a Barrier

Encryption technologies help protect user data from theft and they help secure critical infrastructure and services that societies depend on. But, encryption is also available to criminals and terrorists. This puts law enforcement agencies in a difficult position. In effect, they are faced with the dilemma of how to gather evidence on criminals and other adversaries who may be using encryption, while at the same time, not putting the safety of law-abiding citizens at greater risk. While we at the Internet Society recognize the challenges facing law enforcement, we believe that strong encryption should be available to all Internet users as it is an important technical solution to protect their communications and data.

This dilemma was voiced by U.S. Deputy Attorney General Rod Rosenstein in a recent speech. He argued that “Encrypted communications that cannot be intercepted and locked devices that cannot be opened are law-free zones that permit criminals and terrorists to operate without detection by police and without accountability by judges and juries.”

This problem, claimed Rosenstein, can be solved with what he calls “responsible encryption.” To Rosenstein, “responsible encryption” could “involve effective, secure encryption that allows access only with judicial authorization.” Unfortunately, if Continue reading

Network Engineer Persona: Part Four

Part three introduced the first three key skills. This part presents the introduction to the last three core skills and a call to action.

Key Skill Four

I’m trying very hard to refrain from using the term DevOps, but the fundamentals of the DevOps movement are super important. The DevOps fundamental pillars are improving the flow of work, improving the quality using a feedback loop and sharing. A huge array of books have been created on the topic of DevOps in addition to blog posts and podcasts. If we view the persona of the Network Automation Engineer through the lens of the DevOps persona, the two are very similar. If we are to increase the flow of tasks and improve the quality of them using automation, then we need to be able to fix the issues close to the source of the problems and share knowledge. We do that with logging and an attitude change. Logging is critical for successful automation projects as well as attitude.

Knowing how to transmit logs, how to capture logs, how to sort through them and how to realize events from them is an entire skill. There are software stacks dedicated to this mission like Continue reading

IDG Contributor Network: Why smart consumers are key to IoT security

As the IoT reshaped how companies did their business and how consumers purchased their beloved products, it was simultaneously revolutionizing the field of information security. Many IoT observers contend that not enough has been done to keep it secure, however, and today’s experts are increasingly pointing out that one key facet of IoT security is often forgotten: smart consumers.So how exactly should smart consumers play a role in IoT security, and how can today’s top companies, governments, and IoT-advocates help educate consumers to make better decisions? A brief look at the crucial next step in securing the internet of things shows that creating a generation of smart consumers won’t be easy, but it will certainly be worth the investment.To read this article in full or to leave a comment, please click here

Cisco Stretches ACI Network Fabrics, Eases Management

For disaster recovery, political, and organizational reasons, enterprises like to have multiple datacenters, and now they are going hybrid with public cloud capacity adding in the mix. Having networks scattered across the globe brings operational challenges, from being able to easily migrate and manage workloads across the multiple sites and increased complexity around networks, security to adopting emerging datacenter technologies like containers.

As the world becomes more cloud-centric, organizations are looking for ways to gain greater visibility and scalability across their environments, automate as many processes as possible and manage all these sites as a single entity.

Videos series: Modernizing Java Apps for IT Pros

Today we start releasing a new video series in Docker’s Modernize Traditional Apps (MTA) program, aimed at IT Pros who manage, maintain and deploy Java apps. The video series shows you how to move a Java EE 7 application written to run on Wildfly 3, move it to a Windows Docker container and deploy it to a scalable, highly-available environment in the cloud – without any changes to the app.

These are the first 4 of a 5 part video series in Docker’s Modernize Traditional Apps (MTA) program, aimed at Java IT Pros. The video series shows you how to move a Java EE app on JBoss Wildfly to a Docker container and deploy it to a scalable, highly-available environment in the cloud – without any changes to the app.

Modernizing Java Apps

Part 1 introduces the series, explaining what is meant by “traditional” apps and the problems they present. Traditional apps are built to run on a server, rather than on a modern application platform. They have common traits, like being complex to manage and difficult to deploy. A portfolio of traditional applications tends to under-utilize its infrastructure, and over-utilize the humans who manage it. Docker Enterprise Edition (EE) fixes that, giving Continue reading

[Video] Building a Pure Layer-3 Data Center with Cumulus Linux

One of the design scenarios we covered in Leaf-and-Spine Fabric Architectures webinar is a pure layer-3 data center, and in the “how do I do this” part of that section Dinesh Dutt talked about the details you need to know to get this idea implemented on Cumulus Linux.

We covered a half-dozen design scenarios in that webinar; for an even wider picture check out the new Designing and Building Data Center Fabrics online course.

Cisco Catalysts Supervisor Engines,Interfaces and Modules- Cisco 6500 and Cisco 6800

Today I will talk about the Line cards in the Chassis and explain you where to use which line card and how we design the network with the user count. People asked me so many questions on the line card part and they are always confuse about the use of the line cards in the chassis. The article is based on the Cisco devices where we are using the line cards to accommodate the users in the network at the access layer and to have the smooth traffic flow.

Below image shows the two different Chassis in VSS format where we connect the chassis back to back with the SUP engines. The SUP can be 2T or 6T depends upon the requirement and the design of the campus or enterprise network.

Fig 1.1- VSS using SUP Engines


Let's talk about one by one in details, First I will talk about the Supervisor Engines 6T and 2T. I will not talk about the previous SUP engines as they are going or they are already at the verge of end of sale/support.

New Policy Brief published on Community Networks and Access to Spectrum

Yesterday we published a new policy brief: Spectrum Approaches for Community Networks

Access to affordable and available spectrum is critical for Community Networks. Policy makers can play a key role in ensuring adequate access to spectrum. The policy brief examines the various ways that Community Networks can gain access to spectrum, including:

  • the use of unlicensed spectrum,
  • sharing licensed spectrum, and
  • innovative licensing.

Network operators also play a key role in helping Community Networks. The policy brief outlines recommendations for operators which include:

  • access to backhaul infrastructure at fair rates,
  • equipment and training partnerships, and
  • the sharing of infrastructure as well as spectrum.

Please read our press release for more information about this new paper.  Also visit our World Telecommunications Development Conference (WTDC) 2017 page for more about what our team is doing there in Buenos Aires this week.

The post New Policy Brief published on Community Networks and Access to Spectrum appeared first on Internet Society.

Network Engineer Persona: Part Three

Part three! Let’s get straight to business and carry on where we left off from part two.

Key Skill One

Thinking about automation in an agnostic way is your first footstep. Automation is about data flowing through building blocks that do things and decision points, allow you when to do things.

Removing CLI and replacing it with an abstraction layer isn’t much of a win. For instance, I regularly talk about the process of creating a VLAN and applying it to an Ethernet switch-port on a tagged interface. This somewhat simple ‘workflow’ creates more conversational friction than imagine-able. Let’s work through it.

Task: Create a VLAN
This task requires domain-specific parameters to a VLAN. These are: ‘VLAN_Number’ and ‘VLAN_Description’.

Task: Apply VLAN to Switchport
This task requires domain-specific parameters to a switchport. These are: ‘Port_Name’ and ‘VLAN_Number’.

Note how the inputs flow through the actions within the workflow?

The green arrows descending illustrate the ‘success transition path’ for each action component.

So, what about these questions?
1. Is the VLAN in use?

We can be more specific here, but it adds complications to the answer. Version two is: “Is the VLAN in use in the network zone that the device Continue reading
