What is SAML? SAML is an acronym used to describe the Security Assertion Markup Language (SAML). Its primary role in online security is that it enables you to access multiple web applications using single sign-on (SSO). What is OAuth2?  OAuth2 is an open-standard authorization protocol or framework that provides applications the ability for “secure designated access.” OAuth2 doesn’t share…

Oauth2 and OpenID are important for authentication and authorization. They provide a secure, standardized way for users to log in and access services without needing to enter their credentials each time. In addition, Oauth2 allows third-party applications to access a user’s data without needing to store their credentials directly. In contrast, OpenID will enable users to log in to multiple websites with a single set of credentials. This helps to reduce the risk of user data being stolen or compromised and simplifies the user experience by streamlining the login process. This video will demonstrate how OAuth2 and OpenID Connect are used as you interact with OAuth2 providers and develop your Spring Boot and Spring Security applications.

Choose an app type (e.g., "For Everything Else") and provide the required details.

Once the app is created, go to "Settings" > "Basic" and note down the App ID and App Secret.

Add a product, select "Facebook Login," and configure the Valid OAuth Redirect URIs to http://localhost:8080/login/oauth2/code/facebook.

4. Creating a Spring Boot Application

Create a new Spring Boot project with the necessary dependencies. You can use Spring Initializr or add the dependencies manually to your pom.xml.

Dependencies

<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-oauth2-client</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> </dependencies>

5. Configuring Spring Security for OAuth2 Login

Next, configure Spring Security to use Facebook for OAuth2 login.

application.properties

Add your Facebook app credentials to src/main/resources/application.properties.spring.security.oauth2.client.registration.facebook.client-id=YOUR_FACEBOOK_APP_ID spring.security.oauth2.client.registration.facebook.client-secret=YOUR_FACEBOOK_APP_SECRET spring.security.oauth2.client.registration.facebook.redirect-uri-template={baseUrl}/login/oauth2/code/{registrationId} spring.security.oauth2.client.registration.facebook.scope=email,public_profile spring.security.oauth2.client.registration.facebook.client-name=Facebook spring.security.oauth2.client.registration.facebook.authorization-grant-type=authorization_code spring.security.oauth2.client.provider.facebook.authorization-uri=https://www.facebook.com/v11.0/dialog/oauth spring.security.oauth2.client.provider.facebook.token-uri=https://graph.facebook.com/v11.0/oauth/access_token spring.security.oauth2.client.provider.facebook.user-info-uri=https://graph.facebook.com/me?fields=id,name,email spring.security.oauth2.client.provider.facebook.user-name-attribute=id

Security Configuration

Create a security configuration class to handle the OAuth2 login.import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserService; import org.springframework.security.oauth2.client.userinfo.DefaultOAuth2UserService; import org.springframework.security.oauth2.client.userinfo.OAuth2UserService; import org.springframework.security.oauth2.core.oidc.user.OidcUser; import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler; @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests(authorizeRequests -> authorizeRequests .antMatchers("/", "/error", "/webjars/**").permitAll() .anyRequest().authenticated() ) .oauth2Login(oauth2Login -> oauth2Login .loginPage("/login") .userInfoEndpoint(userInfoEndpoint -> userInfoEndpoint .oidcUserService(this.oidcUserService()) .userService(this.oAuth2UserService()) ) .failureHandler(new SimpleUrlAuthenticationFailureHandler()) ); } private OAuth2UserService<OidcUserRequest, OidcUser> oidcUserService() { final OidcUserService delegate = new OidcUserService(); return (userRequest) -> { OidcUser oidcUser = delegate.loadUser(userRequest); // Custom logic here return oidcUser; }; } private OAuth2UserService<OAuth2UserRequest, OAuth2User> oAuth2UserService() { final DefaultOAuth2UserService delegate = new DefaultOAuth2UserService(); return (userRequest) -> { OAuth2User oAuth2User = delegate.loadUser(userRequest); // Custom logic here return oAuth2User; }; } }

6. Handling Facebook User Data

After a successful login, you might want to handle and display user data.

Custom User Service

Create a custom service to process user details.import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.security.oauth2.core.user.OAuth2UserAuthority; import org.springframework.security.oauth2.client.userinfo.OAuth2UserService; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserService; import org.springframework.security.oauth2.core.oidc.user.OidcUser; import org.springframework.security.oauth2.client.userinfo.DefaultOAuth2UserService; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserRequest; import org.springframework.security.oauth2.client.userinfo.OAuth2UserRequest; import org.springframework.stereotype.Service; import java.util.Map; import java.util.Set; import java.util.HashMap; @Service public class CustomOAuth2UserService implements OAuth2UserService<OAuth2UserRequest, OAuth2User> { private final DefaultOAuth2UserService delegate = new DefaultOAuth2UserService(); @Override public OAuth2User loadUser(OAuth2UserRequest userRequest) { OAuth2User oAuth2User = delegate.loadUser(userRequest); Map<String, Object> attributes = new HashMap<>(oAuth2User.getAttributes()); // Additional processing of attributes if needed return oAuth2User; } }

Controller

Create a controller to handle login and display user info.import org.springframework.security.core.annotation.AuthenticationPrincipal; import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; @Controller public class LoginController { @GetMapping("/login") public String getLoginPage() { return "login"; } @GetMapping("/") public String getIndexPage(Model model, @AuthenticationPrincipal OAuth2User principal) { if (principal != null) { model.addAttribute("name", principal.getAttribute("name")); } return "index"; } }

Thymeleaf Templates

Create Thymeleaf templates for login and index pages.

src/main/resources/templates/login.html

<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Login</title> </head> <body> <h1>Login</h1> <a href="/oauth2/authorization/facebook">Login with Facebook</a> </body> </html>

src/main/resources/templates/index.html

<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Home</title> </head> <body> <h1>Home</h1> <div th:if="${name}"> <p>Welcome, <span th:text="${name}">User</span>!</p> </div> <div th:if="${!name}"> <p>Please <a href="/login">log in</a>.</p> </div> </body> </html>

7. Testing the Integration

Run your Spring Boot application and navigate to http://localhost:8080. Click on the "Login with Facebook" link and authenticate with your Facebook credentials. If everything is set up correctly, you should be redirected to the home page with your Facebook profile name displayed.

Identity, authentication, anonymity; Pseudonymous identity and recovery in an uncaring world. Revision 2.1a

Identity, authentication, anonymity; Pseudonymous identity and recovery in an uncaring world. Revision 2.1a This paper explores managing identity and account recovery, going beyond multi-factor authentication (MFA) and examining the potential role of using proof of observability ledgers. The focus is on observability networks, undeniably signatures, and hard anonymity. The goal is to allow users to recover from catastrophic losses of secret keys, hardware tokens, computers, and mobile devices while still maintaining a pseudonymous identity. The paper also discusses the question of human-based secret recovery and revisits the web of trust in the age of social media. It emphasizes that the users most at risk are the ones who need the highest level of security. To achieve this, the paper proposes using secret sharing methods to create identity control blocks, understanding the difference between statutory identity and persistent global pseudonymous identity, and recognizing why this is important in the modern social context. Mitigating the risks of global identities is also discussed, and the paper proposes bootstrapping the protocol using peer-to-peer methods over existing protocols. The pitfalls of failure to scale are highlighted, and the importance of considering human factors and cryptography engineering in a combined system is emphasized. The paper suggests avoiding federated protocols to prevent monopolistic oligarchies from emerging. Since these identities are not tied to a central service they are not entrapped to a walled garden and can freely move from service to service. With operational conformance to OpenID Oauth2 and Fido U2F they can quickly be deployed to many existing services. To ensure secure key recovery, players use Shamir's secret sharing to publish a specific number of recovery key bits to a subset of peers. The reconvocation key of the primary key is also published this way. Although not all members will sign everyone's key, all group members watch the log, and groups can be of arbitrary sizes based on performance and connectedness. Players should be in multiple groups, and auto-summaries of group hashes are published to prevent rollbacks. In case a player loses their primary hardware key, they can convince N out of M of their key partners to publish their revocation token. All actions in the game use N of M fail/stop multi-party computation, and the game doesn't require a central authority or policy-setting organization since it relies on hardware tokens and published revocation and recovery keys. In practical operation the game will be designed to cause tokens to fail to simulate key loss, as well as designate some players as attackers. Each token will initially be loaded with a “Alias” and “True Name”. Attackers will have “Agent Smith” in the true name field. A play variant may be created where cheating detection by the group can force the reveal of the “True Name”.

Overview

A wide range of setup postman to call d365 services to allow developers and administrators to work programmatically with their data and business logic. For calling these D365 services, Postman is an excellent tool for testing and developing APIs. Your development process can be streamlined by properly configuring Postman to call D365 services, whether you're integrating third-party apps or running regular tests. You may ensure seamless and effective API interactions by following this guide, which will help you through the process of configuring Postman to interface with D365 services.

How to Set Up Postman Step-by-Step to Call D365 Services

Set up and start Postman:

Install Postman by downloading it from the official website.

For your D365 API interactions, open Postman, create a new workspace, or use an existing one.

Obtain Specifics of Authentication:

It is necessary to use OAuth 2.0 authentication in order to access D365 services. If you haven't previously, start by registering an application in Azure Active Directory (Azure AD).

Go to "Azure Active Directory" > "App registrations" on the Azure portal to register a new application.

Make a note of the Application (Client) ID and the Directory (Tenant) ID. From the "Certificates & Secrets" area, establish a client secret. For authentication, these credentials are essential.

Set up Postman's authentication:

Make a new request in Postman and choose the "Authorization" tab.

After selecting "OAuth 2.0" as the type, press "Get New Access Token."

Complete the necessary fields:

Name of Token: Assign a moniker to your token.

Type of Grant: Choose "Client Credentials."

URL for Access Token: For your tenant ID, use this URL: https://login.microsoftonline.com/oauth2/v2.0/token Client ID: From Azure AD, enter the Application (Client) ID.

Client Secret: Type in the secret you made for the client.

Format: https://.crm.dynamics.com/.default is the recommended one.

To apply the token to your request, select "Request Token" and then "Use Token."

Construct API Requests:

GET Requests: Use the GET technique to retrieve data from D365 services. To query client records, for instance:

.crm.dynamics.com/api/data/v9.0/accounts is the URL.

POST Requests: POST is used to create new records. Provide the information in the request body in JSON format. Creating a new account, for instance:

.crm.dynamics.com/api/data/v9.0/accounts is the URL.

JSON body: json

Copy the following code: {"telephone1": "123-456-7890", "name": "New Account"}

PATCH Requests: Use PATCH together with the record's ID to update already-existing records:

.crm.dynamics.com/api/data/v9.0/accounts() is the URL.

JSON body: json

Code {"telephone1": "987-654-3210"} should be copied.

DELETE Requests: Utilize DELETE together with the record's ID: .crm.dynamics.com/api/data/v9.0/accounts()

Add the parameters and headers:

In the "Headers" tab, make sure to include:

Bearer is authorized.

Application/json is the content type for POST and PATCH requests.

For filtering, sorting, or pagination in GET requests, use query parameters as necessary. As an illustration, consider this URL: https://.crm.dynamics.com/api/data/v9.0/accounts?$filter=name eq 'Contoso'

Submit Requests and Evaluate Answers:

In order to send your API queries, click "Send."

Check if the response in Postman is what you expected by looking at it. The answer will comprise status codes, headers, and body content, often in JSON format.

Deal with Errors and Issues:

For further information, look at the error message and status code if you run into problems. Authentication failures, misconfigured endpoints, or badly formatted request data are typical problems.

For information on specific error codes and troubleshooting techniques, consult the D365 API documentation.

Summary

Getting Postman to make a call A useful method for testing and maintaining your D365 integrations and API interactions is to use Dynamics 365 services. Through the configuration of Postman with required authentication credentials and D365 API endpoints, you may effectively search, create, update, and remove records. This configuration allows for smooth integration with other systems and apps in addition to supporting thorough API testing. Developing, testing, and maintaining efficient integrations will become easier with the help of Postman for D365 services, which will improve data management and operational effectiveness in your Dynamics 365 environment.

From Monolithic to Microservices: The Full Stack Developer's Guide 

In software development, the transition from monolithic to microservices architecture represents a major advancement. Because of their coupled components, monolithic programs can have trouble growing and changing to meet evolving business requirements. By dividing applications into smaller, independent services that can be built, deployed, and scaled separately, microservices offer a more adaptable and modular approach. Comprehending this shift is essential for Full Stack Developers to create contemporary, expandable applications. This article offers a thorough how-to for switching from monolithic to microservices architecture, outlining the advantages, difficulties, and recommended procedures for a smooth transfer. 

Why Shift from Monolithic to Microservices?  

Monolithic applications can be difficult to maintain and scale due to their tightly coupled architecture. As applications grow, these challenges multiply, leading to longer development cycles and increased operational costs. Microservices offer a modular approach, allowing individual services to be developed, deployed, and scaled independently. This results in faster release cycles, better fault isolation, and improved scalability. For Full Stack Developers, mastering microservices architecture means being able to build applications that can easily adapt to changing business requirements.  

Key Considerations for a Successful Transition: 

Transitioning from monolithic to microservices is not without challenges. Developers need to consider factors such as service granularity, data management, and inter-service communication. Defining the right level of granularity is crucial to avoid creating too many or too few services. Similarly, managing data consistency across multiple services requires a robust strategy, such as using event-driven architectures or implementing a Saga pattern. Understanding these key considerations will help developers navigate the complexities of microservices architecture. 

Choosing the Right Tools and Frameworks:  

Selecting the right tools and frameworks is critical for a smooth transition to microservices. Developers need to choose container orchestration tools like Kubernetes for deploying and managing microservices. Additionally, frameworks like Spring Boot for Java, Express.js for Node.js, and Flask for Python offer built-in support for microservices development. Familiarity with API gateways, such as NGINX or Kong, is also essential for managing communication between services. 

Ensuring Security in a Microservices Architecture:  

Security in a microservices architecture can be challenging due to the increased number of endpoints. Developers must implement strong authentication and authorization mechanisms, such as OAuth2 and JWT tokens, to secure communications between services. Additionally, monitoring and logging tools like Prometheus and Grafana can help detect and respond to security threats in real-time. 

There are several advantages of switching from monolithic to microservices design, such as increased scalability, flexibility, and quicker release cycles. It does, however, also bring difficulties that call for meticulous preparation and implementation. Full Stack Developers may effectively manage this transformation by being aware of the principal factors, selecting the appropriate tools, and putting strong security measures in place. Developers may create more durable and adaptive modern apps by embracing microservices, which will help them stay competitive in the rapidly changing IT industry.

Oracle Apex Oauth2 Example

OAuth2 in Oracle APEX: A Practical Guide and Example

OAuth2 is a contemporary and secure authorization framework that allows third-party applications to access protected resources on behalf of a user. By implementing OAuth2 in Oracle APEX, you can provide controlled access to your APEX application’s data and functionality, enabling seamless integration with other services.

Why use OAuth2 with APEX?

Enhanced Security: OAuth2 offers a robust security layer compared to traditional username and password-based authentication. It uses tokens rather than directly passing user credentials.

Fine-grained Access Control: OAuth2 allows you to define specific scopes (permissions) determining the access level granted to third-party applications.

Improved User Experience: Users can conveniently authorize applications without repeatedly sharing their primary credentials.

Prerequisites

A basic understanding of Oracle APEX development

An Oracle REST Data Source (ORDS) instance, if you want to integrate with ORDS-defined REST APIs

Steps for Implementing OAuth2 in Oracle APEX

Create an OAuth2 Client:

Within your APEX workspace, navigate to Shared Components -> Web Credentials.

Click Create and select the OAuth2 Client type.

Provide a name, ID, client secret, and any necessary authorization scopes.

Obtain an Access Token:

The method for obtaining an access token will depend on the OAuth2 flow you choose (e.g., Client Credentials flow, Authorization Code flow).

Utilize the Access Token:

Include the access token in the Authorization header of your API requests to protected resources. Use the format: Bearer .

Example: Accessing an ORDS-based REST API

Let’s assume you have an ORDS-based REST API endpoint for fetching employee data that requires OAuth2 authentication. Here’s how you would configure APEX to interact with it:

Create a REST Data Source:

Go to Shared Components -> REST Data Sources.

Set the authentication type to OAuth2 Client Credentials Flow.

Enter your OAuth2 token endpoint URL, client ID, and client secret.

Use the REST Data Source in Your APEX Application:

Create APEX pages or components that utilize the REST Data Source to fetch and display employee data. APEX will automatically handle obtaining and using the access token.

Additional Considerations

Access Token Expiration: OAuth2 access tokens usually have expiration times. Implement logic to refresh access tokens before they expire.

OAuth2 Flows: Choose the most suitable OAuth2 flow for your integration use case. The Client Credentials flow is often used for server-to-server integrations, while the Authorization Code flow is more common for web applications where a user is directly involved.

How to Implement Java Microservices Architecture

Implementing a microservices architecture in Java is a strategic decision that can have significant benefits for your application, such as improved scalability, flexibility, and maintainability. Here's a guide to help you embark on this journey.

1. Understand the Basics

Before diving into the implementation, it's crucial to understand what microservices are. Microservices architecture is a method of developing software systems that focuses on building single-function modules with well-defined interfaces and operations. These modules, or microservices, are independently deployable and scalable.

2. Design Your Microservices

Identify Business Capabilities

Break down your application based on business functionalities.

Each microservice should represent a single business capability.

Define Service Boundaries

Ensure that each microservice is loosely coupled and highly cohesive.

Avoid too many dependencies between services.

3. Choose the Right Tools and Technologies

Java Frameworks

Spring Boot: Popular for building stand-alone, production-grade Spring-based applications.

Dropwizard: Useful for rapid development of RESTful web services.

Micronaut: Great for building modular, easily testable microservices.

Containerization

Docker: Essential for creating, deploying, and running microservices in isolated environments.

Kubernetes: A powerful system for automating deployment, scaling, and management of containerized applications.

Database

Use a database per service pattern. Each microservice should have its private database to ensure loose coupling.

4. Develop Your Microservices

Implement RESTful Services

Use Spring Boot to create RESTful services due to its simplicity and power.

Ensure API versioning to manage changes without breaking clients.

Asynchronous Communication

Implement asynchronous communication, especially for long-running or resource-intensive tasks.

Use message queues like RabbitMQ or Kafka for reliable, scalable, and asynchronous communication between microservices.

Build and Deployment

Automate build and deployment processes using CI/CD tools like Jenkins or GitLab CI.

Implement blue-green deployment or canary releases to reduce downtime and risk.

5. Service Discovery and Configuration

Service Discovery

Use tools like Netflix Eureka for managing and discovering microservices in a distributed system.

Configuration Management

Centralize configuration management using tools like Spring Cloud Config.

Store configuration in a version-controlled repository for auditability and rollback purposes.

6. Monitoring and Logging

Implement centralized logging using ELK Stack (Elasticsearch, Logstash, Kibana) for easier debugging and monitoring.

Use Prometheus and Grafana for monitoring metrics and setting up alerts.

7. Security

Implement API gateways like Zuul or Spring Cloud Gateway for security, monitoring, and resilience.

Use OAuth2 and JWT for secure, stateless authentication and authorization.

8. Testing

Write unit and integration tests for each microservice.

Implement contract testing to ensure APIs meet the contract expected by clients.

9. Documentation

Document your APIs using tools like Swagger or OpenAPI. This helps in maintaining clarity about service endpoints and their purposes.

Conclusion

Implementing a Java microservices architecture can significantly enhance your application's scalability, flexibility, and maintainability. However, the complexity and technical expertise required can be considerable. Hire Java developers or avail Java development services can be pivotal in navigating this transition successfully. They bring the necessary expertise in Java frameworks and microservices best practices to ensure your project's success. Ready to transform your application architecture? Reach out to professional Java development services from top java companies today and take the first step towards a robust, scalable microservice architecture.
