A tour through Merkle Town, Cloudflare’s Certificate Transparency dashboard

A tour through Merkle Town, Cloudflare's Certificate Transparency dashboard

For a quick primer on Certificate Transparency, please read my colleague Nick Sullivan’s post from earlier today. The discussion below expands on that post and details how Cloudflare monitors the health and performance of Certificate Transparency (CT) logs.

A tour through Merkle Town, Cloudflare's Certificate Transparency dashboard

The success of Certificate Transparency rests on the existence of a robust ecosystem of logs and log operators. Without logs that CAs can depend on, it’s not practical for browsers to require that SSL certificates have been logged to be trusted—as Chrome plans to do on April 30. With this deadline fast approaching and others browsers likely to follow suit, it’s critical that the CT ecosystem continues to strengthen and expand with new log operators.

As we wrote about earlier today, Cloudflare recently joined this group of trusted log operators, helping strengthen this critical ecosystem. Now, we’d like to take you on a quick guide through our new publicly accessible tool that tracks the health of all trusted logs. In addition to basic uptime and response times, Merkle Town, provides statistics on the type and frequency of certificates issued, the top issuers, and the inter-dependencies CAs have on existing logs and each other.

IoT security spending to spike above $1.5 billion in the next year

The market for IoT security products is set to grow sharply, as the general IoT market becomes ever more ubiquitous, according to a report released this month by Gartner Research. While there are numerous drivers behind the increased demand for IoT security, a growing sense that regulatory compliance will shortly become an issue is one of the most pressing.The report lists security as the top barrier to success for IoT initiatives, according to a survey on IoT adoption conducted by Gartner. A big part of the problem, the report said, is that businesses often don’t have full control over which devices and software are being used at each level of a given IoT project.To read this article in full, please click here

How NSX Is Tapping into the Human Element Behind Network Virtualization

 

Virtualization can be a tricky concept for some people to wrap their heads around. Trying to explain the functionalities and benefits of technology like VMware NSX can quickly devolve into techno-babble. With that said, we’re trying to take another approach—a more human approach. Below are three customer stories that emphasize a human-interest element behind network virtualization and showcase the power of technologies like NSX to better human lives.

 

NSX Powers a ‘Classroom in the Cloud’ for Illinois Students

 When the technology leaders of Bloomington’s public schools started looking for a way to make advanced, enterprise-level computing and Internet services affordable to students, they went the co-op route and turned to IlliniCloud. IlliniCloud has proven to be a game-changer for a public education system in crisis. The co-op is transforming the technology infrastructures of not just Bloomington’s public school district, but every school district in Illinois with an affordable and efficient model that results in major cost savings for schools, along with upgrades in technology and aging infrastructures.

 

VMware is the backbone of IlliniCloud and a natural fit, according to Jason Radford, CTO of IlliniCloud: “VMware believed in the IlliniCloud. They gave us the tools that were Continue reading

Ansible 2.5: Traveling space and time

Ansible-2-5-Blog-HeaderWelcome to another Ansible release! Version 2.5–“Kashmir”–has a lot of great stuff to play around with, and we're excited to get it in your hands so you can try it out.

Some of the items in this release have been covered in depth in previous Feature Spotlights: AWS EC2 Dynamic inventory plugin, the new Loop keyword, and the all-new ec2_instance module. But those are just appetizers for all of the new things that are included in this release.

Fact Namespacing

In 2.5, we are introducing fact namespacing, which makes Ansible facts available under the ansible_facts namespace (i.e. ansible_facts.os_distribution) without the ansible_ prefix.

Facts will continue to be added into the main namespace directly, but there is now a configuration boolean to enable this. Today, it’s ”On” by default, in a future release, we’ll switch that to “Off”.

Module Blacklisting

We have added a configuration file that enables administrators to filter modules that should be excluded from being used in playbook runs. Operationally, this ensures administrators have more control over which Ansible Modules are approved for use.

New magic vars

Magic vars are variables that Ansible provides to playbook runs without having to be requested. Continue reading

Weekend Reads 032318

Today, we are discussing some of our more complex, heuristic techniques to detect malicious use of this vital protocol and how these detect key components of common real-world attacks. These analytics focus on behavior that is common to a variety of attacks, ranging from advanced targeted intrusions to the more mundane worms, botnets and ransomware. Such techniques are designed to complement more concrete signature-based detection, giving the opportunity to identify such behavior prior to the deployment of analyst driven rules. —John Booth @Azure

List of Third Parties (other than PayPal Customers) with Whom Personal Information May be Shared

There appears to be a huge disconnect here between the EU’s professed concern for keeping Europeans safe — as expressed in the one-hour rule — and the EU’s actual refusal to keep Europeans safe in the offline world. The result is that Europeans, manipulated by an untransparent, unaccountable body, will not be kept safe either online or off. And what if the content in question, as has already occurred, may be trying to warn the public about terrorism? —Judith Bergman @ Gatestone

Ransomware has long been a headache for PC and smartphone users, but in the future, it could be robots that Continue reading

Shedding light on broadband performance for an optimized SD-WAN

A decade ago, if I had asked a network manager to consider using broadband to connect branch offices, he would have looked at me as if I had a second head. Times and opinions change, though, and broadband is now as viable as MPLS or any other network service.The catalyst for this has been the rise of software-defined WANs (SD-WANs). Their multipath capabilities and network optimization make it possible to use broadband for business connectivity, and organizations of all sizes have been jumping aboard this trend. One of the challenges that remain, though, is that not all connections or types of broadband are created equal.Not all broadband is created equal A network manager at a business with branches located nationwide recently told me that his company's preferred broadband type has been cable, but he has been surprised by the variability in the resulting bandwidth by location and time of day. For example, in one large metro area, he is purchasing 50MB of bandwidth, more than adequate for most branches. During the mornings he often sees throughput of 100MB or more. Later in the day, however, when kids get home from school and the Xboxes and Netflix subscriptions start Continue reading
