As part of the Oauth architecture, we have an authorization server that acts as middleman in handling all the permissions very clearly. Instead of providing credentials to another application to access your resources, with Oauth we�ll provide a key that this application will use to retrieve a token with a very specific set of permissions called scopes. The scopes are a representation of our resources in the resource server.
This is an example of how the Oauth flow works, as you can see in the following diagram.
The application that needs access to a specific resource server makes a call to the Oauth Authorization Server first, with the client id and secret previously shared with the application by the authorization server. The scope in this case should represent the service that the application wants to access.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

A microservice is a single business unit where all data and functions that are relevant to a single business purpose are put into one service.
Well, this is the general understanding of a microservice, but what do we really mean by it?
Here we can take the example of Legos, yes, you read that right, Legos.
You may remember when we used to play with Legos that we start building our whole piece from an individual Lego brick.
Just like each Lego brick is independent of each other, each microservices is independent, but come together to make something greater.
Here we can compare each microservice to a single Lego brick.
A single microservice
A complete application (containing multiple loosely coupled microservices)

The book Microservices Security in Action, which I authored with Nuwan Dias is now available to buy online from Amazon and Manning. Nuwan and I spent last 27+ months writing/re-writing the book. It was a marathon effort, but yet a great experience, and we both are very glad to see how it came out at the end! This is the story, which lead us to write the book.
While working at WSO2 for more than a decade, we’ve seen how the integration domain evolved over time from SOAP-based services to JSON/RESTful services and then to microservices. We spent most of our early days at WSO2 contributing to the Apache Axis2 project, which was a popular SOAP engine in those days, and to the Apache Rampart project, which implements many Organization for the Advancement of Structured Information Standards (OASIS) standards for web services security.
Even though SOAP was quite promising in those days, it started to fade rapidly over time, and clearly JSON/RESTful services had won. Most of the microservice implementations we see today follow RESTful design principles.
In the last two to three years, we’ve seen a genuine interest from many companies we’ve worked with to move into microservices architecture, and projects starting from scratch are adopting microservices principles. Most of the early adopters of microservices just wanted to get things done, and worried mostly about implementing functional requirements. They didn’t worry too much about security, although they should have. In many cases, securing microservices would mean securing the interactions among microservices with Transport Layer Security (TLS), and may be, for some, enforcing mutual TLS for service-to-service authentication. But none of them are quite adequate. There are two main reasons many didn’t worry much about security: complexity and awareness.
Some time back, we found that most tools for securing microservices were not easy to use or couldn’t address the challenges specific to microservices deployments. This complexity was a barrier to securing microservices. At the same time, people who didn’t put much effort into security weren’t fully aware of the risks. We started hearing these stories from many of our customers as well as from the extended open source community we work with. That motivated us to write this book on securing microservices. Bringing an idea from inception to reality takes considerable time and effort.
We lived with this idea of writing a book for more than two years until Manning reached out to us. During that period, with the increased adoption of microservices, the infrastructure around microservices security also evolved.
Writing a book about a rapidly evolving domain is bit of a challenge; you never know when your book will be obsolete. After discussing this challenge with the publisher, we decided to put more weight on principles and patterns, and use tools just to demonstrate how to apply those principles and patterns in practice. This was our ground rule in picking up the technology stack for the book. We use Spring Boot/Java to develop all the samples, though we don’t expect you to know either Java or Spring Boot in detail. If you have development experience in any programming language, you should be able to follow all the samples in the book with no difficulty.
Security itself is a larger domain. Securing microservices can mean different things to different people, based on their experiences and expectations. This fact was highlighted by one of the reviewers of the book, who comes from a security testing background.
In our book, we wanted to focus on managing access to microservices. In other words, we wanted to focus on securing access to microservices with authentication and authorization. So, the book doesn’t talk about protecting microservices against different types of attacks, such as SQL injection, cross-site scripting (XSS), cross-site request forgery, and so on.

With an immense number of companies and entities climbing onto the digital bandwagon, cybersecurity considerations have come up as limelight. Besides, new technologies such as Big Data, IoT, and Artificial Intelligence/Machine Learning are gradually more making inroads into our everyday lives, the threats related to cybercrime are mounting as well. Additionally, the usage of mobile and web apps in transacting financial information has put the complete digital stuff exposed to cybersecurity breaches. The inherent risks and vulnerabilities found in such apps can be exploited by attackers or cybercriminals to draw off crucial information data counting money. Internationally, cyber-security breaches have caused a yearly loss of USD 20.38 million in 2019 (Source: Statista). Plus, cybercrime has led to a 0.80 percent loss of the entire world’s Gross domestic product, which sums up to approx. USD 2.1 trillion in the year 2019 alone (Source: Cybriant.com).
In this article, take a look at ten cyber security tools to watch out for in 2021, including NMap, Wireshark, Metasploit, and more!
