Are Huawei Products Unsafe or Insecure ? A Review

I’ve done quite a bit of research in the Huawei issue. There are two key areas that I will cover in this review of the available information.  The network has to work before it can secured.  Software Quality and poor process.  Insider Threats by Chinese Nationals. TL:DR Huawei has substantial problems with product quality and […]

Response: How Important is it to Understand Hardware Architecture?

This reddit post asked the question: For example, I’m going through a Cisco Live presentation on troubleshooting ASR routers, and the first 50 slides or so are completely dedicated to describing the Route Processors, Packet Engines, ASICs, Buffers, etc., and the different paths that packets can take through the hardware. While that’s all obviously important […]

Senegal Kicks Off Enhancing IoT Security Project

On April 4, 2018, the Canadian Multistakeholder Process: Enhancing Internet of Things (IoT) Security held its first convening in partnership with the Canadian Internet Registration Authority (CIRA)CANARIEInnovation, Science and Economic Development (ISED) Canada; and the Canadian Internet Policy and Public Interest Clinic (CIPIC). Over 80 participants from government, academia, public interest, industry, and other organizations attended the first meeting and many have continued to engage at in-person and virtual meetings ever since. Over the past eight months, this group has experienced significant success in the areas of consumer education, labeling, and network resiliency. And these achievements have been well-noted on a global scale.

A delegation from Senegal came to Canada in July to meet with members of the Enhancing IoT Security oversight committee. The group was comprised of government officials, Senegal Chapter members, and staff from the Internet Society’s African Bureau. The delegation met with Canadian government officials, technologists, public interest groups, and North American Bureau staff to learn more about how and why the IoT security project was initiated, and what the group had accomplished to date. The group discussed the significant successes the Canadian multistakeholder group had already achieved, the challenges it faced, Continue reading

Response: Super Micro says no implants on motherboards

I’m convinced that Bloomberg is wrong about the hardware implants. Until they retract the story they don’t have credibility to report on technology.  Supermicro commissioned 3rd party audit and found nothing which is confirmation of many other sources who also refute the claims. The ONLY people making the claim is Bloomberg and there is no […]

Murambinda Works Community Engagement Workshop in Buhera: Meeting Challenges with Opportunity

Over 100 community members, including head masters, government officials, teachers and heads of primary and secondary schools gathered in Buhera rural district council of Zimbabwe on 15 November, eager to engage in discussions related to the initial deployment of the Murambinda Works Community Network. Schools, health and the local authority facilities have been earmarked as the initial benefactors for the inaugural roll out of the Murambinda Works Community Network.

The CEO of Murambinda, Mama Emilie gave a welcoming speech followed by the district school inspector of Buhera who talked about the importance of equipping their schools with ICT. “We cannot imagine a good curriculum that has not taken into consideration ICT. The partnership with Internet Society is a blessing to the district. We want to support it until infinity,” he said. The inspector also mentioned some of the challenges they are facing in their schools including the lack of power, unavailability of computers and connectivity. (Since 2015, 1200 teachers have been trained in ICT, but couldn’t do much with their acquired knowledge.)

TelONE, the national Telecommunications parastatal company with infrastructure in Murambinda Town, was also present at the workshop. “One man cannot make it but we can work together Continue reading

Tech Time is Real Time

Silicon Valley is both an addiction and passion where entrepreneurs seek the realm of the impossible. Real-time language translation, fraud detection, and autonomous vehicle control are being addressed through the use of neural network models, detecting patterns and behaviors across massive amounts of structured and unstructured data. Indeed, change is not only a constant progression in Silicon Valley, it is a continuum in time. Every piece of traditional technology has to imminently become smarter, challenged or be eliminated. While this transformation is especially true for entrepreneurs, invention is not limited to start-ups. I have witnessed several waves of evolution and revolution during my journey in Silicon Valley in both high-tech and networking.

How to tame enterprise communications services

Communications capabilities are essential to the success of organizations everywhere. Voice, email, text messaging, multimedia messaging, file sharing, streaming video, conferencing, collaboration, and more – you can’t do business without them. But as traffic volumes and the number of communications services in use continue to grow, so do the IT and operational challenges.Communications services have historically been provisioned by, and are of course still widely available from, broadband landline and wireless carriers who seek value-added revenue to offset the commodity nature of their “big dumb pipe” core businesses. But there are also numerous third-party solution suppliers, private implementations, and unified communications (UC) product and service capabilities. In addition, an increasing number of cloud-based services – many of which are often aimed squarely at consumer end-users rather than organizations – are seeing significant organizational application, and unfortunately often via backdoor or shadow-IT routes.To read this article in full, please click here

The truth about Black Friday and Cyber Monday

The truth about Black Friday and Cyber Monday

At Cloudflare we handle a lot of traffic on behalf of our customers. Something we all see and hear a lot about at this time of year are Black Friday (23 November this year) and Cyber Monday (26 November) - but just how important are these days on the Internet?

The truth about Black Friday and Cyber Monday
Black Friday by Per-Olof Forsberg, license: CC BY 2.0

To try and answer this question, we took a look at anonymised samples of HTTP requests crossing our network. First of all, let’s look at total page views from across our global network from the last few weeks and see if we can spot Black Friday and Cyber Monday:

The truth about Black Friday and Cyber Monday
All page views

So this is total page views by day (UTC) from November 19 (a week before Cyber Monday) until Monday December 3. Other than follow-the-sun fluctuations in a repeating daily pattern, each whole day is pretty similar in shape and size compared to the last. Black Friday and Cyber Monday aren’t visible in overall traffic patterns.

We have a very diverse set of customers across 12 million domain names and not all of them are selling products or doing so directly online. To identify those websites Continue reading

A new look on your Cloudflare dashboard

A new look on your Cloudflare dashboard

Building a great customer experience is a top priority here at Cloudflare. Over the last week, we have been  slowly rolling out an improvement to our customer dashboard - specifically the zone overview page. We are now ready to share the new dashboard with everyone.

A new look on your Cloudflare dashboard
The new Cloudflare dashboard

Many of the changes you’ll notice first were driven directly by customer feedback. We’ve heard time and time again that site owners would like better visibility of their key analytics, and for it to be easier to apply certain common settings changes. This new dashboard provides both, with a snapshot of several of your key analytics, and a new toolkit area for easy access to key functions. This page has also been redesigned from top to bottom for responsiveness across various devices and screen widths.

Even more interesting is all the work under-the-hood that went into making this release and how it sets the stage for improvements to our customer experience as we look ahead to 2019. This is one of the first pieces of production Product work shipped using our new prototyping framework. We will soon be sharing details of the design systems work that underlies the new experience on Continue reading

Using ss to examine network connections

The ss (socket statistics) command provides a lot of information on network activity by displaying details on socket activity. One way to get started, although this may be a bit overwhelming, is to use the ss -h (help) command to get a listing of the command's numerous options. Another is to try some of the more useful commands and get an idea what each of them can tell you.One very useful command is the ss -s command. This command will show you some overall stats by transport type. In this output, we see stats for RAW, UDP, TCP, INET and FRAG sockets. $ ss -s Total: 524 TCP: 8 (estab 1, closed 0, orphaned 0, timewait 0) Transport Total IP IPv6 RAW 2 1 1 UDP 7 5 2 TCP 8 6 2 INET 17 12 5 FRAG 0 0 0 Raw sockets allow direct sending and receiving of IP packets without protocol-specific transport layer formatting and are used for security appliications such as nmap TCP provides transmission control protocol is the primary connection protocol UDP (user datagram protocol) is similar to TCP but without the error checking INET includes both of the above (INET4 and INET6 can be Continue reading
