Dell EMC and The Amazing Internet Of Things

While at Dell EMC World 2017 I had a very interesting chat with Jason Shepherd, Dell EMC’s Director of IoT Strategy & Partnerships. To be clear, I’m not an expert on the Internet of Things (IOT), and our discussion was a useful reminder how much difference perspective makes when evaluating a technology.

Internet Of Things: Use Cases

When I think about IOT the first thing that comes to mind — naturally enough — are the items most applicable to me, like a smart thermostat, smart door locks, smart light bulbs, and so forth. I work in an enterprise, so I also think about building management in the enterprise, to include things like smart lighting, HVAC, presence sensors, temperature monitoring and more. Both of these environments are ripe for IOT functionality, and are the ones that most of us are likely to encounter on a daily basis.

However, it’s probably obvious that there are many more use cases for IOT devices, including for example:

• industrial (monitoring critical equipment like motors, valves, temperatures, flow meters)
• metropolitan (city-wide automotive/pedestrian traffic monitoring, traffic flows)
• agricultural (monitoring water levels, animal health, production volumes, environmental)
• automotive (monitoring the car’s engine, location, mechanical and electronic Continue reading

Getting Started: Tower Projects and Inventories

Welcome to another post in our Getting Started series. In our previous post, we discussed how you can equip your Ansible Tower instance with users and credentials.

In this post, we will discuss how to set up projects and inventories in your Ansible Tower instance.

What Is A Tower Project?

Tower projects are a logical collection of Ansible Playbooks that are set up with each other based on what they might be doing or which hosts they might interact with.

Playbooks can be managed within Tower projects by either adding them manually to the project base path on your Tower server, (/var/lib/awx/projects) or by importing them from a source control management system (SCM) that is supported by Tower. Examples of SCMs supported by Tower are Git, Subversion and Mercurial. Managing your projects with an SCM is recommended to ensure that only users with assigned access to the repository can change the Playbook before execution, and for the extra layer of accountability and change control it provides. If your Playbooks are managed by an SCM, update options can be selected to “update on launch”, “delete on update” and “clean”.

If you select “update on launch", Tower will sync each Continue reading

LPWAN: The Linchpin for IIoT

Start Using OpenConfig with NAPALM on Software Gone Wild

OpenConfig sounds like a great idea, but unfortunately only a few vendors support it, and it doesn’t run on all their platforms, and you need the latest-and-greatest software release. Not exactly a set of conditions that would encourage widespread adoption.

Things might change with the OpenConfig data models supported in NAPALM. Imagine you could parse router configurations or show printouts into OpenConfig data structures, or use OpenConfig to configure Cisco IOS routers running a decade old software.

Progressive Dutch Municipality Protects Citizen Data and Meets Compliance with VMware NSX

Summary: Municipality of Zoetermeer implements Zero-Trust model with VMware NSX-enabled micro-segmentation for advanced security inside data centers. Zoetermeer follows the Dutch BIG (Baseline Information Security Dutch Municipalities) regulations

Zoetermeer is a modern, fast-growing municipality in the province of South Holland. It provides local services such as water supply, sewage and garbage disposal to around 125,000 residents. As a forward-thinking organization, the municipality of Zoetermeer recognizes that the increasing volume of cyber attacks against organizations today has shown that traditional, perimeter-centric security models are no longer effective.

The municipality responded by working with VMware partner ON2IT IT Services on a solution that wouldn’t treat everything inside the network as trusted. Zoetermeer deployed VMware NSX® network virtualization to facilitate a Zero Trust security model. This Zero Trust model is enabled by the unique micro-segmentation capabilities of VMware NSX.  Zoetermeer is now compartmentalizing different segments of its network and applying automated, fine-grained security policies to individual applications.

“The municipality of Zoetermeer is committed to delivering digital services to our citizens, and also digital tools to enable the best experience for our employees,” said Mr. Van Gaalen, IT Manager, Municipality of Zoetermeer. “But security must remain paramount. Thanks to VMware, we can Continue reading

Technology Short Take #83

Welcome to Technology Short Take #83! This is a slightly shorter TST than usual, which might be a nice break from the typical information overload. In any case, enjoy!

Networking

• I enjoyed Dave McCrory’s series on the future of the network (see part 1, part 2, part 3, and part 4—part 5 hadn’t gone live yet when I published this). In my humble opinion, he’s spot on in his viewpoint that network equipment is increasingly becoming more like servers, so why not embed services and functions in the network equipment? However, this isn’t enough; you also need a strong control plane to help manage and coordinate these services. Perhaps Istio will help provide that control plane, though I suspect something more will be needed.
• Michael Kashin has a handy little tool that functions like ssh-copy-id on servers, but for network devices (leveraging Netmiko). Check out the GitHub repository.
• Anthony Shaw has a good comparison of Ansible, StackStorm, and Salt (with a particular view at applicability in a networking context). This one is definitely worth a read, in my opinion.

Bastion Hosts and Custom SSH Configurations

The idea of an SSH bastion host is something I discussed here about 18 months ago. For the most part, it’s a pretty simple concept (yes, things can get quite complex in some situations, but I think these are largely corner cases). For the last few months, though, I’ve been trying to use an SSH bastion host and failing, and I could not figure out why it wouldn’t work. The answer, it turns out, lies in custom SSH configurations.

In my introduction on using SSH bastion hosts (linked above)—or in just about any tutorial out there on using SSH bastion hosts—brief mention is made of adding configuration information to SSH to use the bastion host. Borrowing from my original post, if you had an instance named “private1” that you wanted to access via a bastion named “bastion”, the SSH configuration information might look like this:

Host private1
  IdentityFile ~/.ssh/rsa_private_key
  ProxyCommand ssh user@bastion -W %h:%p

Host bastion
  IdentityFile ~/.ssh/rsa_private_key

Normally, that information would go into ~/.ssh/config, which is the default SSH configuration file.

In my case, I only allow public key authentication to “trusted” systems (I vaguely recall an article I read a while ago about a Continue reading

Get involved with the Moby Project by attending upcoming Moby Summits!

Last month at DockerCon, we introduced the Moby Project: an open-source project sponsored by Docker to advance the software containerization movement. The idea behind the project is to help the ecosystem take containers mainstream by providing a library of components, a framework for assembling them into custom container-based systems and a place for all container enthusiasts to experiment and exchange ideas. Going forward, Docker will be assembled using Moby, see Moby and Docker or the diagram below for more details.

Moby Summit at DockerCon 2017

Knowing that that a good number of maintainers, contributors and advanced Docker users would be attending DockerCon, we decided to organize the first Moby Summit in collaboration with the Cloud Native Computing Foundation (CNCF). The summit was a small collaborative event for container hackers who are actively maintaining, contributing or generally involved or interested in the design and development of components of the Moby project library in particular: LinuxKit, containerd, Infrakit, SwarmKit, libnetwork and Notary.

Here’s what we covered during the first part of the summit:

• 0:05 – Opening words by Patrick Chanezon
• 9:05 – Moby Project Q&A with Solomon Hykes and Justin Cormack
• 60:14 – Quick update on containerd by Michael Continue reading

How to conduct an IoT pen test

Penetration testing was much like taking a battering ram to the door of the fortress. Keep pounding away and maybe find a secret backdoor to enter through. But what happens if pieces of the network are outside of the fortress? With the flurry of Internet of Things devices, is it harder to conduct a pen test with that many devices and end points?Claud Xiao, principal security researcher, Unit 42 at Palo Alto Networks, said for just testing some network services on IoT devices in a black box way, the difficulty level and the steps are similar with regular pen testing. But if you're discovering vulnerabilities via analyzing firmware or via analyzing wireless communications (e.g., Bluetooth or ZigBee), that's much harder.To read this article in full or to leave a comment, please click here
