Configuring the Web Application Firewall with PowerShell.

A quick guide on how to connect and work with the Azure WAF from PowerShell.

Microsoft Azure Application Gateway is a Layer 7 application delivery controller (ADC) offered as a service in Azure. It provides load balancing, SSL termination, end-to-end SSL, URL path-based routing, and basic web application firewall (WAF) functionality. Working with the WAF, I usually build a basic configuration in the Portal before exporting the ARM JSON, which, then becomes my primary method to working on this service. Why JSON you may ask… One of my biggest gripes with the Azure Firewall solutions currently is based on thier CRUD (Create, Read, Update and Delete) interface.

However, running aware from the problem rarely is a good fix for the issue; My latest battle has been Pester. The testing framework builds on Powershell, and by the grace of God, now shipped as part of the Windows 10 operating system.

My Journey to the Internet of Things

While preparing to use the NodeMCU, Reminiscing IoT evolution after 20 Years

In a previous post, I referred to an embedded device which is called a NodeMCU. This device is a developer kit, designed to make it easy to develop and test programs for the embedded ESP8266 System on a Chip. Many manufacturers are offering both developer and production kits which leverage this SoC; including the Wemos D1, Lolin, and in my case the NodeMCU. The function of these developer kits is to add some supporting features, for example, a USB to serial converter which makes programming a lot easier, in addition to a couple of buttons, and maybe an LED or two, for testing some simple scenarios with.

NodeMCU Pinouts

Quick reference for the Pin connections on the NodeMCU boards

Over the last number of years I have deployed various Raspberry PI’s around my home, to add more features to how we interact in the house. However, as wonderful as the PI is, there are alternative options available which are more appropriate to the various tasks which I need to address. NodeMCU For the past year, I have been using a tiny board, known as the NodeMCU which is essentially a developer board for a module know as the ESP8266.

Implementing Comments on a Static Site

At this point we are almost ready to go live with our site, however, one of the cornerstones to growing and sharing is communication. Wordpress In the world of Wordpress, this was a standard core feature, which leveraged the fact that the pages were rendered on demand from a backend database. In this scenario, the same approach is offered to maintain a commenting platform. However, as I noted earlier; given that Wordpress powers a very large portion of the blogging surface of the internet; it is an obvious target for hacking, just refer to the CVS database for a glimpse of what this looks like in reality.

Adding Content Flow

Using pipelines for flow static site content between markdown and foundation

With the heavy lifting done in creating the site building mechanics and a solid foundation to build and share upon; our final objective is to automate the process of connecting these two stages. Release Pipeline Technically the goal we are speaking about is the Release Pipeline which will take the artefact (our site .ZIP file) that we created in the Build Pipeline in our previous topic Constructing a new Home with Jekyll and Azure DevOps; and publish this to our storage account.
