Penn State secures building automation, IoT traffic with microsegmentation

It was time to get a handle on BACnet traffic at Penn State.BACnet is a communications protocol for building automation and control (BAC) systems such as heating, ventilating and air conditioning (HVAC), lighting, access control and fire detection. Penn State standardized on BACnet because of its openness.[ For more on IoT see tips for securing IoT on your network, our list of the most powerful internet of things companies and learn about the industrial internet of things. | Get regularly scheduled insights by signing up for Network World newsletters. ] “Any device, any manufacturer – as long as they talk BACnet, we can integrate them,” says Tom Walker, system design specialist in the facility automation services group at Penn State. “It’s a really neat protocol, but you have to know the quirks that come with deploying it, especially at scale.”To read this article in full, please click here

Stateful vs Stateless firewalls: Which one to use when?

Firewalls provide traffic filtering and protects the trusted environment for the untrusted. A firewall can be stateful or stateless A stateful firewall is capable of tracking connection states, it is better equipped to allow or deny traffic based on such knowledge.  A TCP connection for example goes through the handshake (SYN-SYN+ACK-SYN), to EASTABLISHED state, and … Continue reading Stateful vs Stateless firewalls: Which one to use when?

OpenPower At The Inflection Point

When IBM launched the OpenPower initiative publicly five years ago, to many it seemed like a classic case of too little, too late. But hope springs eternal, particularly with a datacenter sector that is eagerly and actively seeking an alternative to the Xeon processor to curtail the hegemony that Intel has in the glass house.

Perhaps the third time will be the charm. Back in 1991, Apple and IBM and Motorola teamed up to create the AIM Alliance, which sought to create a single unified computing architecture that was suitable for embedded and desktop applications, replacing the Motorola 68000 processors …

London & Barcelona developers, we want to meet you this week

London & Barcelona developers, we want to meet you this week

London & Barcelona developers, we want to meet you this week

Are you based in London or Barcelona? Drop by the Cloudflare London office to meet Kenton Varda, lead architect of Cloudflare Workers, front end developers Marta Bondyra and David Sancho from Typeform, or drop by the Typeform office in Barcelona to hear from Jason Harmon, Typeform’s Chief Platform Officer. My Developer Relations teammates and I are visiting these cities over the next two weeks. We’d love to meet you and invite you to the three events we’re hosting.

Our first stop is the Cloudflare London office. Developers from our Cloudflare Apps partner, Typeform, are leading a talk on Tuesday, March 27th. The lead architect of Cloudflare Workers, Kenton Varda, is going to lead a follow-up talk about edge computing on Wednesday, March 28th.

Event #1: Building for a tech audience: Great dev lessons for adventurous makers

London & Barcelona developers, we want to meet you this week

Tuesday, March 27th: 18:00-20:00

Location: Cloudflare London - 25 Lavington St, Second floor | SE1 0NZ London

Creating software from scratch, although fun, can be time consuming and expensive. Marta and David, both developers at Typeform, will tell you why their teams built tools to make the lives of developers a little easier and what they learned along the way.

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
