BrandPost: An efficient network: The Fabric of a complex paperless hospital system

As CTO of a large regional hospital system, I know that the network is vital to everything. I consider the network in the same critical category as electricity, oxygen, and water. It needs to be available 24x7x365 to support Concord Hospital’s half a million patients and over 5,000 network users across our 30 locations.Because we don’t do anything on paper, the network can never go down. Extreme Fabric Connect has solved that problem for us. It provides a secure, self-healing, highly-available network to serve our patients effectively in our complex paperless environment. All the Benefits of MPLS, None of the HeadachesTo read this article in full, please click here

BrandPost: The cloud payoff: Ensuring hybrid works for your enterprise

As more and more enterprises move to hybrid cloud, there are some interesting relationships among enterprises, Internet and cloud exchanges, and colocation providers to satisfy IT strategies through hybrid clouds. In its Strategic Roadmap for Data Center Infrastructure, Gartner notes that “by 2019, 80% of enterprises will have an IT strategy that includes multiple Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) providers.” This is up from only 10% in 2015, while “by the end of 2018, 10% of enterprises will close their on-premises data centers entirely.”To read this article in full, please click here

Cloudflare is adding Drupal WAF Rule to Mitigate Critical Drupal Exploit

Drupal has recently announced an update to fix a critical remote code execution exploit (SA-CORE-2018-002/CVE-2018-7600). This patch is to disallow forms and form fields from starting with the “#” character which results in remote code execution.

We have also in accordance, just pushed out a rule to block requests matching these exploit conditions for our Web Application Firewall (WAF). You can find this rule in the Cloudflare ruleset in your dashboard under the Drupal category with the rule ID of D0003.

Building Our New Website: POSSE and Sharing on Facebook, Twitter, LinkedIn, Google+ and More

As we built our new website, one of my own guiding principles was “POSSE“, a content publishing model from the “IndieWeb” movement. The idea is:

Publish on your
Own
Site,
Syndicate
Elsewhere

Essentially, make sure you own your own content – and then share it out onto other sites and services. (See the IndieWeb page about POSSE for more discussion.) Make your own website the “hub” for all your content, and then have spokes going out to all the other places where people might discover and learn about your content.

To me, this model is the best way to support the principles of the open Internet, while engaging people in the places where they already are.

This is part of a series of posts about the evolution of our new site.

Why does this matter?

We aren’t just publishing reports, papers, blog posts and articles for the sake of talking about what we are doing.

We are publishing content to bring about change that ensures the Internet remains open, globally connected, and secure. As we said in our vision statement for the new website:

Our website is a driving force in Continue reading

Policing, Shaping, and Performance

Policing traffic and shaping traffic are two completely different things, but it is hard to know, in the wild, what the impact of one or the other will have on a particular traffic flow, or on the performance of applications in general. While the paper under review here, An Internet-Wide Analysis of Traffic Policing, is largely focused on the global ‘net, specifically from a content provider’s perspective, it contains lessons for just about every network operator who needs to manage Quality of Service (QoS) in a sane and meaningful way.

Flach, Tobias, Pavlos Papageorge, Andreas Terzis, Luis Pedrosa, Yuchung Cheng, Tayeb Karim, Ethan Katz-Bassett, and Ramesh Govindan. 2016. “An Internet-Wide Analysis of Traffic Policing.” In Proceedings of the 2016 ACM SIGCOMM Conference, 468–482. SIGCOMM ’16. New York, NY, USA: ACM. https://doi.org/10.1145/2934872.2934873.

Traffic policing involves setting up a queue with a pool of tokens. For some unit of traffic—assume a packet here—received, a token is consumed. When a packet is transmitted, the token is added back to the pool. If the pool is sized correctly, short bursts in the traffic stream will be allowed through, but if the application attempts to establish a session using more bandwidth Continue reading

Let’s Encrypt Offers Free Multi-Domain HTTPS Certificates

Let’s Encrypt, a nonprofit certificate authority launched in 2016, has delivered on its pledge to offer free certificates that enable secure HTTP connections for complete domains.

The organization’s new wildcard certificate service, allowing website operators to secure all subdomains of a domain with a single certificate, should help the Internet become more secure by enabling wider deployment of HTTPS, Josh Aas, executive director of the Internet Security Research Group, wrote in a blog post. (Full disclosure: the Internet Society is a major sponsor of Let’s Encrypt.)

Last July, Let’s Encrypt had promised that it would offer free wildcard certificates. With the recent release of the ACMEv2 [Automatic Certificate Management Environment] Protocol, the organization delivered on that promise.

“Wildcard certificates can make certificate management easier in some cases, and we want to address those cases in order to help get the Web to 100% HTTPS,” Aas wrote. “We’re excited about the prospect of a 100% HTTPS Web and we’re working hard to get there.”

A wildcard certificate isn’t recommended for all websites, Aas noted. In most cases, other certificates, such as single-domain ones, will be more appropriate.

Although wildcard certificates enable streamlined management of HTTPS, some security Continue reading

History Of Networking – Dinesh Dutt – Divergence of Compute and Networking

The operation and management of compute and networking are unique in the the tools and skill-sets required, but do they necessarily need to be? Dinesh Dutt joins Network Collective to talk about the divergence of compute and networking, how it hasn’t always been this way, and why he believes it should return to being a unified effort.

People are really worried about IoT data privacy and security—and they should be

A new study from the Economist Intelligence Unit (EIU) shows that consumers around the world are deeply worried about in how their personal information is collected and shared by the Internet of Things (IoT). But let’s be honest, the problem isn’t that unsophisticated consumers are panicking for no reason. In fact, consumers are merely picking up on the very real inherent risks and uncertainties surrounding IoT data.Businesses are also worried about IoT security I’ll get into the results and implications of the survey in a moment, but first I want to note that business and professionals are equally concerned. Perhaps that’s why Gartner just predicted that IoT security spending will hit $1.5 billion by the end of the year, up 28 percent from 2017, and more than double to $3.1 billion by 2021.To read this article in full, please click here
