Spring security using OAuth2 with Microsoft AzureAD B2C

Introduction

Microsoft Azure provides the capability to integrate social-logins in the application by using AzureAD B2C. The good thing about that is you’ll have a single Authorization server (Azure) and different IDP like Google, Facebook, GitHub, or any custom IDP.

To achieve this we need to create 1 B2C tenant and configure App Registration, IDP, and create UserFlow. The below video tutorial covers all these steps and guide you on how to integrate Azure B2C with spring security.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

If you have any, feel free to share them in the comments! I’d love to know them.

Spring Security Overview

In this article, we will take a bird’s eye view of Spring Security to understand what it is used for and what it has to offer us. Anything on the web is a potential victim of an attack. Unfortunately, securing a web application and implementing features like authorization and authentication are no walk in the park in a world where even the richest, most innovative technology companies get hacked. So when our boss gives us a task to secure the application, should we sit and wait, scared, not knowing what to do? Of course not.

Whether or not you are going to use Auth0 to secure your Spring app, you will need to know the basics of Spring Security to secure your application rapidly, and this makes it a must-know framework for any Spring developer. The thing with Spring Security is: It is difficult. Not because it is poorly designed or could be easier to use, but because of the complexity of its domain: Application security. Complex problems require technically sophisticated solutions, and security is one of them.

If you have ever taken a glance at a Spring Security-related documentation or tutorial, you might be scared of how complicated it looks. I mean, take a look at this picture from Wikipedia:

It is very natural to feel overwhelmed, especially if you are also new to Spring. Spring Security is a huge framework, but once you get the basics down, you can easily get the task of securing your app done by integrating it with an IDaaS service like Auth0 without the hassle of implementing everything yourself.

Spring: A Static Web Site Generator Written By GitHub Issues

Spring

Spring is a blog engine written by GitHub Issues, or is a simple, static web site generator. No more server and database, you can setup it in free hosting with GitHub Pages as a repository, then post the blogs in the repository Issues.

You can add some labels in your repository Issues as the blog category, and create Issues for writing blog content through Markdown.

Spring has responsive templates, looking good on mobile, tablet, and desktop.Gracefully degrading in older browsers. Compatible with Internet Explorer 10+ and all modern browsers.

Get up and running in seconds.

• Fork the Spring repository as yours.
• Goto your repository settings page to rename Repository Name.
• Hosted directly on GitHub Pages from your project repository, you can take it as User or organization site or Project site(create a gh-pages branch).
• Also, you can set up a custom domain with Pages.

Secondly

• Open the index.html file to edit the config variables with yours below.

$.extend(spring.config, {
  // my blog title
  title: 'Spring',
  // my blog description
  desc: "A blog engine written by github issues [Fork me on GitHub](https://github.com/zhaoda/spring)",
  // my github username
  owner: 'zhaoda',
  // creator's username
  creator: 'zhaoda',
  // the repository name on github for writting issues
  repo: 'spring',
  // custom page
  pages: [
  ]
})

• Put your domain into the CNAME file if you have.

Spring Security: Develop a REST-Service Secured With OAuth2, Bitbucket and JWT

How to use Spring Security to develop a REST-service secured with OAuth2, Bitbucket authorization server and JWT

We are going to develop a small REST-service secured using OAuth2 protocol with Bitbucket as an authorization server. At first it may seem unusual to use a third-party authorization server, but imagine that you are developing a CI (Continuous Integration) server and would like to have access to the user’s resources (e.g projects, repositories) in a version control system. For example, the same approach is used in Drone.io  and Travis CI .
