Exactly two years ago, at this same time, I was coming home from Milan after attending the first Italian WordPress Contributor Day. I didn’t know then what it would have meant to me, but it was the beginning of something awesome.
I started using WordPress as a CMS in 2009, but it was just in 2015, in Milan, that I found out the Community and the several opportunities to contribute to this successful open source project. Have a look at the Make area to read more about the different teams working on WordPress.
In the previous article, I introduced Keycloak, an open source project for identity and access management developed by the RedHat Community. I went through how to install it, boot it and how to access the Keycloak Admin Console for the first time.
Continuing from where I left, in this new article I’d like to talk about how to configure Keycloak so that you can later use it for managing authentication and authorisation for a web application as well as for a web service. I’ll show you how to create a new realm, define roles and add users.
Throughout this series, you’re going to see more features and details about Keycloak, but I suggest you check the helpful and detailed official documentation for any doubt or curiosity.
Access Control, Authentication and Authorisation
Managing authentication and authorisation is an essential task in every good-designed web application or service. Keycloak makes it very easy and effective, letting you focus on the application business logic rather than on the implementation of security features.
Before going on, it is worth briefly recalling the definition of some fundamental security properties (from NIST glossary):
Access Control: “the process of granting or denying specific requests to: 1) obtain and use information and related information processing services; and 2) enter specific physical facilities (e.g., federal buildings, military establishments, border crossing entrances)”.
Authentication: “verifying the identity of a user, process, or device, often as a prerequisite to allowing access to resources in an information system”.
Authorisation: “access privileges granted to a user, program, or process or the act of granting those privileges”.
Lately, I’ve been working with Keycloak, so I decided to better delve into it and write about it.
This article is the first of a series where I’d like to introduce Keycloak as a solution to manage authentication and authorisation, how to install it and which are the fundamental concepts and configurations.
Then I’d like to explain how to use it to secure Spring Boot, Spring Security and AngularJS applications and services, analyse the implementation when using a relational database to store users and finally how to manage users from Java thanks to the Admin REST API.
What is Keycloak?
Keycloak is an open source project developed and maintained by the RedHat Community.
“Keycloak is an open source Identity and Access Management solution aimed at modern applications and services. It makes it easy to secure applications and services with little to no code.”
Setting up HTTPS for Spring Boot is very easy, all you need to do is:
Getting an SSL certificate;
Configuring SSL in Spring Boot.
We can generate an SSL certificate ourselves (self-signed certificate). Its use is intended just for development and testing purposes. In production, you should use a certificate issued by a trusted Certificate Authority (CA). Whether you’re going to generate a self-signed certificate or you have already got one by a CA, I’ll show you how to enable HTTPS in a Spring Boot application.
This morning I gave a talk about how to get started with WordPress Plugin Development at WordCamp Torino 2017.
Here you can find the video and the slides of my talk, enjoy 🙂
WordPress Plugins are powerful tools that let us extend WordPress and turn it into whatever we want. What’s their secret? Join me if you want to know more about them and get started developing your own Plugin! I’ll tell you a story about magic, dangerous pirates, brave bowmen and ancient castles…
49 472 WordPress Plugins are available in the official repository. That’s a huge number! And they are just the Plugins available on wordpress.org. They are much more. For example, think about vendors that sell their own Plugins on their platforms or the thousands of Plugins loaded on GitHub, but never submitted to the official repository.
For many people Plugins are surrounded by mystery. It seems that WordPress provides us with a powerful magic wand to get anything we want. To turn WordPress into whatever we want.
What is a Plugin?
The shortest answer is a package of code. More specifically, a package of PHP code. That’s it.
The most straightforward Plugin is made up of a single unique PHP file. For example Hello Dolly, a Plugin that you’ve probably never used, but you have seen it at least once since it is delivered together with WordPress.
It’s important to understand how Plugins are related to WordPress itself. There are three major components: Core, Themes and Plugins. The Core is the application itself. Themes allow to display some data to users and to choose the look and presentation of your website. Finally, we have Plugins.
“It is a truth universally acknowledged, that each person in possession of a good website, must have used WordPress.”
That’s how our story begins, just like Jane Austen’s Pride and Prejudice. Join me on this journey through the World of WordPress!
