It’s A Wireless Problem, Right?

How many times have your users come to your office and told you the wireless was down? Or maybe you get a phone call or a text message sent from their phone. If there’s a way for people to figure out that the wireless isn’t working they will not hesitate to tell you about it. But is it always the wireless?

Path of Destruction

During CWNP Wi-Fi Trek 2019, Keith Parsons (@KeithRParsons) gave a great talk about Tips, Techniques, and Tools for Troubleshooting Wireless LAN. It went into a lot of detail about how many things you have to look at when you start troubleshooting wireless issues. It makes your head spin when you try and figure out exactly where the issues all lie.

However, I did have to put up a point that I didn’t necessarily agree with Keith on:

Cascadia Code | Windows Command Line Tools For Developers

Another free and open monospaced font for code development this time from Microsoft. A key differentiator is the inclusion of ligatures for programming symbols (see below). Ligature support is rare among text editors and very rare for TTF encoded fonts. Its more common to see OTF ligatures supported. Also, no italics support yet. Creating fonts […]

Opinionated Automation: Packaged, Extensible & Closed Systems

Network engineers for the last twenty years have created networks from composable logical constructs, which result in a network of some structure. We call these constructs “OSPF” and “MPLS”, but they all inter-work to some degree to give us a desired outcome. Network vendors have contributed to this composability and network engineers have come to expect it by default. It is absolute power from both a design and an implementation perspective, but it’s also opinionated. For instance, spanning-tree has node level opinions on how it should participate in a spanning-tree and thus how a spanning-tree forms, but it might not be the one you desire without some tweaks to the tie-breaker conditions for the root bridge persona.

Moving to the automated world primarily means carrying your existing understanding forward, adding a sprinkle of APIs to gain access to those features programmatically and then running a workflow, task or business process engine to compose a graph of those features to build your desired networks in a deterministic way.

This is where things get interesting in my opinion. Take Cisco’s ACI platform. It’s closed and proprietary in the sense of you can’t change the way it works internally. You’re lumped with a Continue reading

Privacy Regulations Are Evolving: Are Organizations Ready?

Privacy statements are both a point of contact to inform users about their data and a way to show governments the organization is committed to following regulations. On September 17, the Internet Society’s Online Trust Alliance (OTA) released Are Organizations Ready for New Privacy Regulations? The report, using data collected from the 2018 Online Trust Audit, analyzes the privacy statements of 1,200 organizations using 29 variables and then maps them to overarching principles from three privacy laws around the world: General Data Protection Regulation (GDPR) in the European Union, California Consumer Privacy Act (CCPA) in the United States, and Personal Information Protection and Electronics Document Act (PIPEDA) in Canada. 

In many cases, organizations lack key concepts covering data sharing in their statements. Just 1% of organizations in our Audit disclose the types of third parties they share data with. This is a common requirement across privacy legislation. It is not as onerous as having to list all of the organizations; simply listing broad categories like “payment vendors” would suffice. 

Data retention is another area where many organizations are lacking. Just 2% had language about how long and why they would retain data. Many organizations have Continue reading

How to decommission a data center

About the only thing harder than building a data center is dismantling one, because the potential for disruption of business is much greater when shutting down a data center than constructing one.The recent decommissioning of the Titan supercomputer at the Oak Ridge National Laboratory (ORNL) reveals just how complicated the process can be. More than 40 people were involved with the project, including staff from ORNL, supercomputer manufacturer Cray, and external subcontractors. Electricians were required to safely shut down the 9 megawatt-capacity system, and Cray staff was on hand to disassemble and recycle Titan’s electronics and its metal components and cabinets. A separate crew handled the cooling system. In the end, 350 tons of equipment and 10,800 pounds of refrigerant were removed from the site.To read this article in full, please click here

Video: The Need for Network Layers

After identifying some of the challenges every network solution must address (part 1, part 2, part 3) we tried to tackle an interesting question: “how do you implement this whole spaghetti mess in a somewhat-reliable and structured way?

The Roman Empire had an answer more than 2000 years ago: divide-and-conquer (aka “eating the elephant one bite at a time”). These days we call it layering and abstractions.

In the Need for Network Layers video I listed all the challenges we have to address, and then described how you could group them in meaningful modules (called networking layers).

You need free ipSpace.net subscription to watch the video, or a paid ipSpace.net subscriptions to watch the whole webinar.

Backup the data in AWS Elastic Block Store

A recent Amazon outage resulted in a small number of customers losing production data stored in their accounts. This, of course, led to typical anti-cloud comments that follows such events. The reality is that these customers data loss had nothing to do with cloud and everything to do with them not understanding the storage they were using and backing it up.Over Labor Day weekend there was a power outage in one of the availability zones in the AWS US-East-1 region.  Backup generators came on, but quickly failed for unknown reasons. Customers’ Elastic Block Store (EBS) data is replicated among multiple servers, but the outage affected multiple servers. While the bulk of data stored in EBS was fine or was able to be easily recovered after outage, .5 percent of the data could not be recovered. Customers among the .5 percent who did not have a backup of their EBS data actually lost data.To read this article in full, please click here

IoT Privacy for Policymakers: Solutions Need Informed Discussion

The consumer Internet of Things market is growing exponentially – one prediction suggests that people will be using 25 billion connected devices by 2021. These new products promise innovation and convenience, but they can also erode privacy boundaries and expose consumers to risk without their knowledge or consent. Is that a good bargain?

The policy brief “IoT Privacy for Policymakers” explores this question and more.

Do consumers have enough information and choice to make meaningful decisions? Do vendors and service providers have the opportunity and incentive to bring privacy-enhancing innovations to the market? Can the downsides of IoT be mitigated through policy actions – and if so, how?

IoT Privacy for Policymakers” explains the scope and nature of IoT privacy and the issues it raises. As ever, those issues are multi-party. They cross the boundaries of jurisdictions and sectoral regulations. There are no single-stakeholder solutions, so a multistakeholder approach is needed. Solutions need informed discussion that includes consumer rights, economic incentives, technical options, and regulatory measures. This paper is a positive step in that direction.

The policy brief also includes a “how to” on implementing Privacy by Design and four Guiding Principles and Recommendations:
