Building Bulletproof Angular Apps: Leveraging .NET for Next-Level Cybersecurity

Introduction

Overview of the Topic: In the bustling world of IT, melding Angular with .NET forms a formidable shield for applications against cyber threats. Here, we’ll explore how integrating these platforms enhances app development and security. With rising digital data breaches, safeguarding applications isn’t just a feature; it’s a necessity. This is especially true for Angular applications which are often targeted due to their widespread use. By the end, you’ll grasp how Angular and .NET join forces to fortify apps against cyber threats. You’ll walk away with actionable strategies to lock down your applications.

Understanding Angular and .NET Ecosystems

Angular is renowned for its scalability and powerful framework, making it a preferred choice for front-end development due to its ease in creating dynamic web applications. For instance, a company developing a user-friendly dashboard for their customers might choose Angular to ensure the interface is responsive and interactive. On the other hand, the .NET framework is a robust platform ideal for backend development, offering extensive libraries and runtime environments for server-side logic and database operations. This means that the same company can rely on .NET to manage their server-side processes, like handling user data and transactions securely.

Integrating Angular with .NET through APIs creates a seamless synergy, enabling Angular to manage the UI while .NET handles backend processes, resulting in a robust and efficient infrastructure. Imagine an online retail store where Angular powers the product display and user interactions, while .NET manages the inventory, payment processing, and order fulfilment behind the scenes. This integration ensures that the application is both user-friendly and capable of handling complex backend operations, providing a smooth and reliable experience for both developers and end-users.

Implementing Security Best Practices in Angular

Securing Client-Side Operations

• Data Sanitization: Ensure data entering your apps via forms or searches is sanitized to prevent XSS attacks.
• Secure Routing: Use Angular guards to protect routes from unauthorized access.

Ensuring secure user access is paramount in Angular applications. By implementing OAuth for authentication and configuring route security, you can ensure that only authorized users access sensitive data and functionalities.

Staying proactive in vulnerability management is crucial for maintaining application security. Regularly updating Angular’s dependencies and leveraging tools like Retire.js to identify and address outdated libraries can significantly reduce the risk of vulnerabilities that could compromise your application’s integrity and data security.

Leveraging .NET for Enhanced Security

.NET’s built-in Identity framework is invaluable for managing users’ access, offering customization and scalability to fit most enterprise environments. Data protection is fundamental, and .NET facilitates encryption of data both at rest and in transit, providing robust defence against breaches. Additionally, using .NET middleware enhances security by performing multiple tasks such as logging, authentication, and error handling, adding an extra layer of protection.

Advanced Security Techniques

Incorporating HTTPS and secure tokens is essential for ensuring the security of your applications. Using HTTPS secures the communication channel, preventing eavesdropping and man-in-the-middle attacks. For example, when you visit your bank’s website, HTTPS ensures that your data, such as login credentials and account information, remains encrypted and secure. Similarly, tokens like JWT (JSON Web Tokens) provide secure mechanisms for user authentication across services. Imagine a single sign-on system where you log in once and gain access to multiple applications securely; JWTs make this possible by verifying your identity without repeatedly exposing your credentials.

Threat detection and response are critical components of a robust security strategy. .NET offers tools like Microsoft Identity’s Conditional Access, which provides real-time threat analytics and response capabilities. For instance, if unusual login activity is detected, such as an attempt from a different country, Conditional Access can automatically prompt additional verification steps or block access altogether. This proactive approach helps protect your applications from malicious activities, ensuring that potential security risks are mitigated before they can cause harm.

Adopting secure coding practices is fundamental in building resilient applications. Writing code with security in mind from the outset can prevent vulnerabilities from being introduced. For example, a developer working on a new e-commerce platform might use .NET’s Code Analysis toolkit to identify and fix security issues during the development phase. This tool can highlight potential vulnerabilities like SQL injection or cross-site scripting, allowing the developer to address them early on. By incorporating these best practices, developers can ensure that their codebase remains secure and reliable, ultimately protecting the end-user’s data and maintaining their trust.

Testing and Maintenance

Regular penetration testing is crucial for .NET/Angular applications. It involves simulating real-world attacks to identify and address potential vulnerabilities proactively, ensuring robust security measures are in place.

Conducting periodic security audits is essential to ensure your .NET/Angular applications comply with security policies and procedures. These audits help identify and rectify security gaps, ensuring continuous protection against evolving threats.

Updates and Patch Management

Keep Angular and .NET frameworks updated. Regular patches are released to fix vulnerabilities and offer new features.

Summary

Integrating Angular with .NET can transform the security landscape of your applications by combining client-side operations with advanced server-side techniques for a comprehensive approach to securing apps. As cybersecurity evolves, the partnership between Angular and .NET is poised to adapt, continually offering cutting-edge protections. Consider how you can implement these strategic insights in your current Angular and .NET projects to fortify your applications. Start today, and build a safer digital tomorrow.

How to build a RESTful Web API using .NET Core 6

.NET 6 is the latest LTS (Long Term Support) release currently and will be supported until November 12, 2024.

This API will manage movie records stored in a relational database (SQL Server) as described in the table below:

The sections of this post will be as follows:

• What is REST?
• Creating a Web API Project
• Adding a Model
• Adding a Database Context
• Creating Database with Migrations
• Creating API Controller and Methods

You will need the following tools installed on your computer:

• Visual Studio 2022
• .NET 6.0 SDK
• Microsoft SQL Server Express

What is REST?

RESTful APIs conform to the REST architectural style.

REST, or REpresentational State Transfer, is an architectural style for providing standards between computer systems on the web, making it easier for systems to communicate with each other.

REST relies on client-server relationship. This essentially means that client application and server application must be able to evolve separately without any dependency on each other.

REST is stateless. That means the communication between the client and the server always contains all the information needed to perform the request. There is no session state in the server, it is kept entirely on the client’s side.

REST provides a uniform interface between components. Resources expose directory structure-like URIs.

REST is not strictly related to HTTP, but it is most commonly associated with it. There are four basic HTTP verbs we use in requests to interact with resources in a REST system:

• GET— retrieve a specific resource (by id) or a collection of resources
• POST— create a new resource
• PUT— update a specific resource (by id)
• DELETE— remove a specific resource by id

In a REST system, representations transfer JSON or XML to represent data objects and attributes.

REST has had such a large impact on the Web that it has mostly displaced SOAP-based interface design because it’s a considerably simpler style to use.

Creating a Web API Project

Open Visual Studio 2022 and select Create a new project and then select ASP.NET Core Web API:

and give a name to your project in the following screen and then click Next.

In the next screen, select .NET 6.0 as the framework and click Create:

At this point you have a starter project as follows:

In the Program.cs you can see that Swagger support is added automatically to your project:

And also Swashbuckle.AspNetCore NuGet package is added as a dependency.

Now, let’s run (Ctlr+F5) the project to see the default output. When the browser opens and the Swagger UI is shown, select the GET method in the WeatherForecast part and then select Try It Out and Execute:

Also, you can use the curl URL shown in the Swagger UI for this method and see the result of the URL in the browser:

When you run the application, the default URL comes from the launchSettings.json:

And the result values come from the GET method of the WeatherForecastController:

As you see, values here are hard coded and randomness is added to generate different values.

In your Web API, you will create your own records in an SQL server database and will be able to view, update and delete them through REST API endpoints.

Adding a Model

Now, you will implement your data model class.

In Solution Explorer, right-click the project. Select Add -> New Folder and name the folder Models.

Then right-click the Models folder and select Add->Class. Name the class Movie.cs and click Add.

Next, add the following properties to the class:

The Id field is required by the database for the primary key.

Entity Framework Core

You will use your model with Entity Framework Core (EF Core) to work with a database.

EF Core is an object-relational mapping (ORM) framework that simplifies the data access code. Model classes don’t have any dependency on EF Core. They just define the properties of the data that will be stored in the database.

In this post, you will write the model classes first and EF Core will create the database. This is called Code First Approach.

Let’s add the EF Core NuGet packages to the project. Right-click on the project and select Manage NuGet Packages… and then install the following packages:

Adding a Database Context

The database context is the main class that coordinates Entity Framework functionality for a data model. This class is created by deriving from Microsoft.EntityFrameworkCore.DbContext class.

Now, right-click the Models folder and select Add ->Class. Name the class MovieContext and click Add. Then add the following code to the class:

The preceding code creates a DbSet<Movie> property for the entity set.

In Entity Framework terminology, an entity set typically corresponds to a database table and an entity corresponds to a row in the table.

The name of the connection string is passed into the context by calling a method on a DbContextOptions object. For local development, the ASP.NET Core configuration system reads the connection string from the appsettings.json file.

We need to add our connection string to the appsettings.json. You will use the local SQL server instance in your machine and you can define the connection string as follows:

 

You can change the database name if you want.

Dependency Injection

ASP.NET Core is built with Dependency Injection (DI). Services (such as the EF Core DB context) are registered with DI during application startup. Components that require these services are provided with these services via constructor parameters.

Now, you will register your database context to the built-in IOC container. Add the following code to Program.cs:

Creating Database with Migrations

Now, you will create the database using the EF Core Migrations feature.

Migrations lets us create a database that matches our data model and update the database schema when our data model changes.

First, you will add an initial Migration.

Open Tools -> NuGet Package Manager > Package Manager Console(PMC) and run the following command in the PMC:

Add-Migration Initial

The Add-Migration command generates code to create the initial database schema which is based on the model specified in the MovieContext class. The Initial argument is the migration name and any name can be used.

After running the command, a migration file is created under the Migrations folder:

As the next step, run the following command in the PMC:

Update-Database

The Update-Database command runs the Up method in the Migrations/{time-stamp}_Initial.cs file, which creates the database.

Now, you will check the database created. Open View -> SQL Server Object Explorer.

You will see the newly created database as below:

As you see, the Movie table and the Migrations History table are created automatically. Then a record is inserted into the migration history table to show the executed migrations on the database.

Creating API Controller and Methods

In this section, you will create the Movies API Controller and add the methods to it, and also will test those methods.

Let’s add the controller first. Right-click on the Controller folder and select Add -> Controller.. and then select API Controller – Empty as below:

Click Add and give a name to your controller on the next screen.

MoviesController is created as below:

As you see, the class is decorated with the [ApiController] attribute. This attribute indicates that the controller responds to web API requests.

MoviesController class inherits from ControllerBase.

Next, we will inject the database context mentioned in the previous section through the constructor of the controller. Add the following code:

Now, you will add CRUD (create, read, update, and delete) action methods to the controller. Let’s start with the GET methods.

GET Method

Add the following code to the MoviesController:

GetMovies method returns all the movies and GetMovie(int id) method returns the movie having the Id given as input. They are decorated with the [HttpGet] attribute which denotes that a method responds to an HTTP GET request.

These methods implement two GET endpoints:

• GET /api/Movies
• GET /api/Movies/{id}

You can test the app by calling the two endpoints from a browser as follows:

• https://localhost:{port}/api/movies
• https://localhost:{port}/api/movies/{id}

The return type of the GetMovie methods is ActionResult<T> type. ASP.NET Core automatically serializes the object to JSON and writes the JSON into the body of the response message. The response code for this return type is 200, assuming there are no unhandled exceptions. Unhandled exceptions are translated into 5xx errors.

Routing and URL Paths

The URL path for each method is constructed as follows:

Start with the template string in the controller’s Route attribute (Route(“api/[controller]”)). Then replace [controller] with the name of the controller, which by convention is the controller class name minus the Controller suffix. For this sample, the controller class name is MoviesController, so the controller name is movies.

ASP.NET Core routing is case insensitive.

Testing the GetMovie Method

Now you will test these endpoints. Before that, let’s insert some movie records into your table.

Go to the SQL Server Object Explorer and right-click the Movies table and select View Data:

Then add some movie records manually to the table:

You do not need to add data for the Id column as SQL Server automatically handles this for us.

Now, you can test the GET endpoints. Start (Ctlr+F5) the application:

Select the first GET method and click Try it out -> Execute:

This shows all of the movies in the application.

Next, click the second GET method and click Try it out and enter one of the Ids above in the id field and click Execute:

If no item matches the requested Id, the method returns a 404 NotFound error code.

POST Method

Add the following code to the MoviesController:

PostMovie method creates a movie record in the database. The preceding code is an HTTP POST method, as indicated by the [HttpPost] attribute. The method gets the value of the movie record from the body of the HTTP request.

The CreatedAtAction method:

• Returns an HTTP201 status code, if successful. HTTP 201 is the standard response for an HTTP POST method that creates a new resource on the server.
• Adds a Locationheader to the response. The Location header specifies the URI of the newly created movie record.
• References the GetMovieaction to create the Location header’s URI.

Testing the PostMovie Method

Start the application and then select the POST method in the Movies section.

Click Try it out and enter the movie information that you want to add in the request body:

and click Execute.

Response status code is 201 (Created) and a location header is added to the response as seen below:

You can paste this location URL in the browser and see the response there too:

Also, you can check this record from the Movies table in your local database:

PUT Method

Add the following code to the MoviesController:

PutMovie method updates the movie record with the given Id in the database. The preceding code is an HTTP PUT method, as indicated by the [HttpPut] attribute. The method gets the value of the movie record from the body of the HTTP request. You need to supply the Id both in the request URL and the body and they have to match. According to the HTTP specification, a PUT request requires the client to send the entire updated entity, not just the changes.

The response is 204 (No Content) if the operation is successful.

Testing the PutMovie Method

Start the application and then select the PUT method in the Movies section.

Click Try it out and enter the movie information that you want to update in the request body and the Id of the movie in the id field:

and then click Execute.

We can check the updated state of the movie from GET method with Id in the Swagger UI or directly from the browser as below:

We can see the updated info in the database as well:

 

If you try to update a record that does not exist in the database you get 404 Not Found error:

DELETE Method

Add the following code to the MoviesController:

DeleteMovie method deletes the movie record with the given Id in the database. The preceding code is an HTTP DELETE method, as indicated by the [HttpDelete] attribute. This method expects Id in the URL to identify the movie record we want to delete.

Testing the DeleteMovie Method

Start the application and then select the DELETE method in the Movies section.

Click Try it out and enter the Id of the movie you want to delete in the id field:

and then click Execute.

We do not need to supply a request body as you might have noticed. The response status is 204 No Content.

If you try to get this movie record using the browser you get 404 Not Found error as expected:

You can check as well from the database that the record is deleted:

ASP.NET Core Features in .NET 7

It is no news that Microsoft is working very hard on improving and bringing new features to the .NET framework or to its C# programming language. This time Microsoft is targeting web development and is focusing on ASP.NET Core, which will apparently come hand in hand with the .NET 7 version.

Some time ago Microsoft released Preview 1 of ASP.NET Core on .NET 7 and the amount of new features is great, so let’s see the new features!

New Minimal API Improvements

The first of the new features will bring improvements in minimal APIs, especially in IFormFile and IFormCollection. With this new improvement you will be able to use IFormFileand IFormCollection to handle and manage file uploads in a much easier way.

Microsoft warns that if you want to use these new functions with authentication, anti-forgery is required, but so far Microsoft has not implemented such support. However, they reassure us that it is on the roadmap of .NET 7.

Support for such requests with client certificates or cookie headers is currently inactive. Let’s take a look at the example provided by Microsoft to see this new ASP.NET Core feature in action:

The next new enhancement for the minimal APIs in ASP.NET Core comes for Steam and PipeRider.

To understand in what kind of scenario these new minimal APIs would be used, let’s imagine that we need to store data in a blob storage or queue it in some queue provider like Azure. In this case we can use Steam and PipeRider to bind the body of a request and later process it in the cloud.

However, Microsoft warns us three details to achieve a correct functioning of these minimal APIs:

• The Streamwill always be the same object as Body when ingesting any type of data.
• The Streamcannot be read again more than once (not rewindable) since by default the request body is not stored in the buffer.
• As the underlying buffers will end up being reused and discarded, both Streamand PipeRider cannot be used outside of the action handler.

The last improvement in the minimal APIs that Microsoft brings in this Preview 1 is about JSON configuration. Through ConfigureRouteHandlerJsonOptions we will be able to manually configure the options and settings of the minimal API endpoints using JSON.

This improvement has been introduced mainly, as Microsoft says, to avoid confusion with Microsoft.AspNetCore.Mvc.JsonOptions.

New client source generator for SignalR

This is the next new feature that ASP.NET Core will bring in .NET 7. This new source code generator for SignalR introduced by Microsoft has the ability to generate code (both sending and receiving) strongly typed based on developer-defined interfaces.

This especially applies to SignalR hub interfaces, there would be no need to use them in loosely-typed methods, we now have the option to reuse them in the client. At the same time, there is the possibility of implementing an interface that contains the methods and at the same time the client can take advantage of that interface to call any method that is part of the hub.

The good thing is that Microsoft has let us see the use and operation of this new SignalR generator. Let’s see how Microsoft uses it:

• First you need to add a reference to AspNetCore.SignalR.Client.SourceGenerator.
• Then the following classes must be added to the project: HubClientProxyAttributeand HubServerProxyAttribute :

The next step is to add a static partial class and write the following static partial methods together with the attributes HubServerProxy and HubClientProxy in this way:And finally, we would use the partial methods and that’s it:That’s it, that’s how easy it is to use the new SignalR client source generator.

Razor Pages and MVC views with nullable models

We continue with the next improvement brought by Microsoft. This time they have focused on improving the user experience of the checks and for this, they have implemented the nullable view for the checks that are made of null state of any ASP.NET Core application. In this case this is the example that Microsoft provides us:

Unfortunately there are no further examples or use cases for this new feature. Hopefully Microsoft will continue to release new features and talk more about the ones already revealed.

Validate errors with JSON property names

Thanks to this new ASP.NET feature you will be able to manually configure with “SystemTextJsonValidationMetadataProvider” the validation to use the JSON property names.

Previously as the names of the properties that a model has, commonly were implementation details, managing them from a single page application was difficult.

If you want to know more about this feature, I recommend you, as always, to consult the original source: Use JSON property names in validation errors

Injection services in Blazor

Injecting services into Blazor? attributes Yes, thanks to this improvement you will be able to inject almost any type of service into custom validation attributes. To do so, the ValidationContext will be configured by Blazor to be used as a service provider.
