Cisco issues critical security warnings on SD-WAN, DNA Center

Cisco has released two critical warnings about security issues with its SD-WAN and DNA Center software packages. The worse, with a Common Vulnerability Scoring System rating of 9.3 out of 10, is a vulnerability in its Digital Network Architecture (DNA) Center software that could let an unauthenticated attacker connect an unauthorized network device to the subnet designated for cluster services. More about SD-WAN How to buy SD-WAN technology: Key questions to consider when selecting a supplier How to pick an off-site data-backup method SD-Branch: What it is and why you’ll need it What are the options for security SD-WAN? A successful exploit could let an attacker reach internal services that are not hardened for external access, Cisco stated.  The vulnerability is due to insufficient access restriction on ports necessary for system operation, and the company discovered the issue during internal security testing, Cisco stated.To read this article in full, please click here

Validation vibes: How we’ve won the praise of customers and employees alike

The success of a company is often defined by two key factors: how your customers feel about you and how your employees feel about you. We’re excited to share that recently we’ve had some great validation by both!

Customer validation

We’re very honored to work with a variety of innovative companies that are breaking the status quo with open networking principles in data centers designed to scale. All of our customers have realized the need for an open, modern data center and are looking to build infrastructure with purpose. From web-scale giants to visionary enterprises, we give them all the ability to build something “EPIC.”

This was recently highlighted when for the second year in a row, our customers have rallied around our vision for the future of data center networking and recognized us as “The Best Data Center Networking 2019” with their reviews through Gartner Peer Insights.

As Gartner puts it, “The Gartner Peer Insights Customers’ Choice is a recognition of vendors in this market by verified end-user professionals, taking into account both the number of reviews and the overall user ratings.” To ensure fair evaluation, Gartner maintains rigorous criteria for recognizing vendors with Continue reading

With Tableau, SaaS king Salesforce becomes a hybrid cloud company

I remember a time when people at Salesforce events would hand out pins that read “Software” inside a red circle with a slash through it. The High Priest of SaaS (a.k.a. CEO Marc Benioff) was so adamant against installed, on-premises software that his keynotes were always comical.Now, Salesforce is prepared to spend $15.7 billion to acquire Tableau Software, the leader in on-premises data analytics.On the hell-freezes-over scale, this is up there with Microsoft embracing Linux or Apple PR people returning a phone call. Well, we know at least one of those has happened.To read this article in full, please click here

2019 Hackathon@AIS: Testimonials from the Trainers

What is Hackathon@AIS?

The Internet, with its endless supply of knowledge and information, has become a strategic element in nearly all economic endeavors in Africa. To build tactical awareness among primary stakeholders as well as resiliency and robustness into Internet-enabled grids, the Internet Society and AFRINIC have organized the third Hackathon@AIS event, which is taking place in Kampala, Uganda, from 19-20 June 2019.

Network engineers, software developers, and computer science students from across Africa are gearing up for another round of collaborative computer programming aimed at introducing participants to existing and evolving Internet standards development that can help further their careers through shared skillsets.

The first Hackathon@AIS was held in 2017 in Nairobi and attracted 39 participants from 12 countries. The second event, held in 2018 in Dakar, attracted 75 participants from 15 countries. Both events consisted of three different tracks led by expert facilitators from across the globe. This year, the event consists of five tracks spanning different fields, and again we’ve called on expert facilitators from around the world to share their expertise and guidance.

The Hackathon is a breeding ground for talent that can change the world through innovation and create productivity and efficiency in business. Continue reading

Cloudflare’s Ethereum Gateway

Today, as part of Crypto Week 2019, we are excited to announce Cloudflare's Ethereum Gateway, where you can interact with the Ethereum network without installing any additional software on your computer.

This is another tool in Cloudflare’s Distributed Web Gateway tool set. Currently, Cloudflare lets you host content on the InterPlanetary File System (IPFS) and access it through your own custom domain. Similarly, the new Ethereum Gateway allows access to the Ethereum network, which you can provision through your custom hostname.

This setup makes it possible to add interactive elements to sites powered by Ethereum smart contracts, a decentralized computing platform. And, in conjunction with the IPFS gateway, this allows hosting websites and resources in a decentralized manner, and has the extra bonus of the added speed, security, and reliability provided by the Cloudflare edge network. You can access our Ethereum gateway directly at https://cloudflare-eth.com.

This brief primer on how Ethereum and smart contracts work has examples of the many possibilities of using the Cloudflare Distributed Web Gateway.

Continuing to Improve our IPFS Gateway

When we launched our InterPlanetary File System (IPFS) gateway last year we were blown away by the positive reception. Countless people gave us valuable suggestions for improvement and made open-source contributions to make serving content through our gateway easy (many captured in our developer docs). Since then, our gateway has grown to regularly handle over a thousand requests per second, and has become the primary access point for several IPFS websites.

We’re committed to helping grow IPFS and have taken what we have learned since our initial release to improve our gateway. So far, we’ve done the following:

Automatic Cache Purge

One of the ways we tried to improve the performance of our gateway when we initially set it up was by setting really high cache TTLs. After all, content on IPFS is largely meant to be static. The complaint we heard though, was that site owners were frustrated at wait times upwards of several hours for changes to their website to propagate.

The way an IPFS gateway knows what content to serve when it receives a request for a given domain is by looking up the value of a TXT record associated with the domain – the DNSLink Continue reading

Real-Life SD-WAN Experience

SD-WAN is the best thing that could have happened to networking according to some industry “thought leaders” and $vendor marketers… but it seems there might be a tiny little gap between their rosy picture and reality.

This is what I got from someone blessed with hands-on SD-WAN experience:

Nines are not enough: meaningful metrics for clouds

Nines are not enough: meaningful metrics for clouds Mogul & Wilkes, HotOS’19

It’s hard to define good SLOs, especially when outcomes aren’t fully under the control of any single party. The authors of today’s paper should know a thing or two about that: Jeffrey Mogul and John Wilkes at Google¹! John Wilkes was also one of the co-authors of chapter 4 “Service Level Objectives” in the SRE book, which is good background reading for the discussion in this paper.

The opening paragraph of the abstract does a great job of framing the problem:

Cloud customers want strong, understandable promises (Service Level Objectives, or SLOs) that their applications will run reliably and with adequate performance, but cloud providers don’t want to offer them, because they are technically hard to meet in the face of arbitrary customer behavior and the hidden interactions brought about by statistical multiplexing of shared resources.

When it comes to SLOs, the interests of the customer and the cloud provider are at odds, and so we end up with SLAs (Service Level Agreements) that tie SLOs to contractual agreements.

What are we talking about

Let’s start out by getting some terms straight: SLIs, SLOs, SLAs, and Continue reading
