Key Takeaways:
● Server-side frameworks somewhat offers security control over custom software development.
● Each of the server-side framework offers different security controls.
● However, instead of relying on a framework for security, knowing the vulnerability helps you.
Security is not a priority for many businesses when they are choosing a custom solution.
They create it for capability, competitive differentiation, operational efficiencies, or because of limitations with off-the-shelf products.
Most modern custom software applications have a lot of security capabilities in the server-side frameworks in which they are built.
This article will provide an explanation of how server-side platforms can be used for secure custom application development.
Also, what each major server-side platform offers, and why the right server-side platform and the right development team are the secret to creating functional applications that will actually be secure.
Why Does Security Begins at the Framework Level?
The logic of starting security at the framework level needs to be articulated before looking at what individual frameworks provide.
The vulnerabilities resulting in the majority of successful attacks: injection attacks (SQL injection being the most popular), broken authentication, insecure data exposure, cross-site scripting (XSS), cross-site request forgery (CSRF), and misconfigured security settings.
A secure back-end structure offers a solid basis for developers, with security features that assist lower such vulnerabilities.
When these protections are baked into the framework and turned on by default, the dev team doesn’t have to build them from scratch. The biggest practical advantage of mature server-side frameworks over building application infrastructure is this default security posture.
Each server framework offers different security capabilities that we will discuss below.
Django: Designed With Security
Django's security features are the most robust in any major web framework.
● SQL Injection Protection: Django's ORM will automatically use parameters for all its database queries, so no SQL injection can occur if the developer doesn't do a thing.
● CSRF Protection: Django provides default CSRF middleware that is used to validate all requests sent via POST, PUT, PATCH, and DELETE methods with a per-session token, thereby preventing CSRF attacks across sites.
● Cross-site Scripting Protection: Django automatically escapes HTML characters in template output by default, thus preventing XSS attacks in the template.
● Clickjacking Protection: The X-Frame-Options middleware option helps to prevent the application from being embedded in frames within another domain
● Ensure Passwords Are Stored Securely: Django uses PBKDF2 password hashing by default, and supports bcrypt and Argon2 through standard configuration.
Laravel: Security as a Built-In Feature of the Workflow
Laravel takes a multifaceted approach; both built-in security and workflow conventions work together to help make secure development as easy as possible.
● CSRF Protection: Laravel generates a token for every active user session that is active and checks for it each time a request is made to change state. The @csrf Blade directive is what makes the inclusion of the token in forms a single line.
● SQL Injection Prevention: Laravel's Eloquent ORM and query builder always generate parameterized database queries.
● Authentication Scaffolding: Laravel's built-in authentication system can be extended with Laravel Breeze, Jetstream, or Sanctum for API authentication, offering secure, tested authentication infrastructure that most applications can leverage instead of building their own
All Cookies are encrypted with Laravel; there is also a powerful encryption service that uses AES-256-CBC encryption available when storing and transmitting sensitive data.
Node.js: Security Through Tooling
While flexible like some of the other alternatives, Node.js is more lax than Django or Laravel when it comes to security.
Unlike Django's middleware pipeline, the framework doesn't impose security patterns. The security of a Node.js application is mostly dependent on the development team's selection and adherence to security rules.
It does not mean that security needs to be a default feature of the framework. Here are the key security practices when developing and managing custom software for Node.js:
● Helmet.js: A library of middleware for setting security-related HTTP headers, offering X-Frame-Options, Content-Security-Policy, X-XSS-Protection, and more; several common categories of vulnerabilities in one package.
● Input Validation: Using libraries like Joi, Zod, or express-validator, the API boundary strictly validates the input, safeguarding against invalid or malicious data reaching the business logic or database queries.
● Parameterized Queries: Prevents SQL injection like Django's ORM does, using an ORM such as Sequelize or Prisma, or using parameterized query functions in the database drivers.
Security Features Do Not Ensure Security
It is crucial to have an idea of the security of a server-side framework. It is also crucial to comprehend what they do not offer reliance.
And that is where the development team can make the difference regarding the security of the finished application.
Known vulnerability patterns are covered through frameworks. They will NOT stop you from getting:
● Weaknesses in the business logic implemented by the application, including potentially bypassable authorization checks and legitimate but miscontrolled workflows that result in privilege escalation
● All dependencies that are added to an app are an attack surface. The security of the application's dependencies on libraries and packages is not covered by the framework-level security.
● In many cases, developers end up forgetting to turn off CSRF middleware due to test failure; this results in bypassing Django’s protection. The security of a framework can only be achieved if it is set up appropriately.
Final Words: How RCV Technologies Tackles Security in Custom Software Development?
Security is not a post-launch concern, or whether the features of a framework are turned on; it's a discipline of engineering that is integral to the entire process of developing custom software at RCV Technologies.
Security requirements are always a major input in creating applications at RCV Technologies.
All of RCV's custom Applications are designed and analyzed through OWASP to create Applications that are not only technically sound, but are designed to defend the business, the data, and the end users they serve.
