How can you design a web application that is both secure and private, but also easy to use?

Encryption is Key. Encryption plays a key role in ensuring digital information security. ... User Authentication. User authentication is a crucial component of web application security. ... Regular Security Audits. ... Secure File Uploads: ... Access Control.

Common mistakes developers make, which may compromise the security of your data: - Simple password to access your database. Use strong passwords with recommended characters and length for your database users. - Sharing across DB connection strings. Don't use any unsecure platforms to share the DB connection strings. - Check-in the db username/password or connection string into code. Do not check-in any part of your db conn string. - Non-secure storage of secrets/connection-strings in build or deployment pipelines or even on cloud or on-prim machines. - Allowing all IPs/domains to connect to your production database. - Manipulating your web-app/db authN/authZ for testing. Keep testing environment/context different.

Designing a secure, private, and user-friendly web app demands a balanced strategy. Encrypt data in transit and at rest, employ robust authentication, and implement access controls. Regular backups and vigilant monitoring are crucial for threat detection and recovery. Respect user privacy by minimizing data collection, obtaining explicit consent, and adhering to data protection regulations. Anonymize sensitive data to enhance privacy protection. User-friendly interfaces should simplify registration and login, integrate multi-factor authentication, and ensure intuitive navigation. Informative feedback builds user confidence.

To secure a web application you must follow the following: - Encrypt sensitive data in transport - Encrypt sensitive data in storage (e.g. disk encryption, at-rest, files, and within a running database) - Data backup regularly and all backed-up data should be encrypted - For secure data erasure on SSDs or other modern storage devices use NIST SP 800-88 standards - There should be a proper cryptographic key management process (generation, exchanges, storage, safeguards, use, vetting and replacement) - Use KeyValult to store various keys, secrets and certificates used on the systems at various stages. - Access control: Use RBAC, ABAC or PBAC - Use secure coding techniques adopted from the first day of the software development life cycle

Proteger os dados começa antes do sistema ser construído, pensando em camadas de proteção da aplicação como um todo. Garantir que banco de dados esteja criptografado, portas do servidores web fechadas para acesso externo. A porta 443 aberta, garantir que seja acessada somente com certificado SSL autorizado. Quando se trata de proxy reverso, adicionar flags de proteção, não deixar a versão do seu sevidor web disponível, seja Nginx, apache2 ou qualquer outro. Manter bibliotecas das aplicação sempre atualizadas.

Every web application should have a privacy policies page where you have to mention what data you collect, why you collect it, how you use it, and who you share it with. - Comply with PCI DSS Security Standards if your application store, process or transmit cardholder data - If the system or products use a third party to collect, store, process, or transmit cardholders, mention everything clearly - Comply with HIPAA if your application handles patient health information - Use multi-factor authentication - Ask for users' consent before storing users' data or tracking users by placing cookies on the users' machine - When a user deletes the account, remove all the related information from the system

In my opinion securing data in a web app means turning information into a secret code only trusted people can understand. It involves making sure only the right people get in (authentication), those people can only see what they're allowed to (authorization), and the info is protected against hackers by using special locks (encryption). Regular updates, keeping copies of info, and watching out for trouble also help keep everything safe

Organizations must prioritize the protection of user data, implementing security procedures, collect only important data, incript it, notify users about type of data that has been collected in the privacy policies.

Es súper importante que un usuario medio. Definamos a este como un usuario sin muchos conocimientos informáticos. Tiene que de forma intuitiva usar la aplicación sin problema alguno. Que los flujos sean claros y simples debiendo estos tener los step mínimos posibles.

User-Friendly Experience Intuitive Navigation Faster Learning Curve Reduced Cognitive Load Increased User Engagement Efficient Task Completion Consistent Branding Better Accessibility Adaptability to Different Devices Reduced Costs Faster Load Times Minimized User Errors Improved Aesthetics Adoption by a Broader Audience Alignment with User Expectations

User Interface is the primary and important step for any application either it is mobile app or web application. Since every people will first interact from UI. So, if we have extra ordinary functionality but the UI is not easy to understand then that it is worth less. UI design should be minimal, easy to understand and more convenient for accessibility. Whenever we create any web application then first thought comes in our mind that this application is going to be used by non-technical people who don't have too much knowledge about the technology.

The initial impact of a web application is determined by its user interface, rather than the backend. A well-designed web application can captivate users and potentially keep them engaged. The following points are provided to aid in improving the user interface: - The UI should support various assistive technologies such as screen readers - The UI should have various themes such as dark, light etc. - The UI should adhere to Web Content Accessibility Guidelines (WCAG) - The UI should be intuitive and the users should understand it without any guide - There should be some guided tours and tooltips when a user visits the site first time - The web application design should be mobile-first design or mobile-first approach

Uno de las claves en el desarrollo de aplicaciones es la simplicidad de la interfaz de usuario, pero más importante es saber a quién va dirigida la aplicación web. A veces queremos hacer cosas muy llamativas o “locas” olvidándonos de quienes realmente la va a usar, y ese es el aspecto más importante a la hora de desarrollarla. Hay que facilitar el uso, el aprendizaje y la accesibilidad a todos los usuarios, haciendo hincapié en que siempre sepa en qué parte se encuentra o cómo continuar un proceso. Por último es importante diseñarla de tal forma que el usuario pueda asimilar conceptos rápidamente y pueda ejercer el autoaprendizaje sobre la aplicación.

An example for improving performance at frontend would be to use critical rendering path, such that only the important content is loaded first and then lazy load rest of the resources of the page on a virtualised scroll, another way to improve frontend would be using web-pack module federation for building micro frontend architecture.

Web development is vague and technology is evolving every day. To get on top of the business, the application should be optimized both in the front end and back end. A few techniques that can optimize performance are: 1) Use GraphQL to avoid over-fetching or under-fetching data from the server 2) Use CDN to deliver static content to the end users 3) Use proper Logging, Analytical tools, Monitoring and Alerting tools to know about the system 5) Automate the whole system to avoid human errors 6) Use CI/CD pipelines to seamlessly build and deploy the application 7) Use both static and dynamic code analysis tools 8) Use GRPC where it fits because of its high-performance

Uma aplicação web exige recursos, e na maioria das vezes recursos caros. Acredito além da otimização temos de pensar na utilização desses recursos, então saber escolher a tecnologia para cada aplicação é um começo bom, usar o que a linguagem de programação tem de melhor e o que o servidor tem de melhor fazendo a boa escolha de tecnologia. Agora escolher a arquitetura, a ideia é deixar na cloud, saber se a aplicação vai ter de ser criada usando um microsserviço ou um monolito, porque microsserviços não são bala de prata, sem sempre são a melhor escolha, então a arquitetura adequada pra aplicação dar pra ter ideia do quanto terá de otimização. Adicionar o Front em um CDN, otimiza o carregamento, usar filas também otimiza tarefas demoradas.

Continuous effort is required for the development and upkeep of web applications. Right from the start, it is crucial to prioritize elements like clean code and appropriate architecture. Implementing an efficient code review process is essential to ensure the maintenance of high-quality code. - Use vulnerability scanning tools periodically on the web application - Periodically do Penetration testing - Write effective unit testing, integration testing, end-to-end testing, UI automation testing - Update the front end and back end with the latest libraries and frameworks - Update the system periodically to install the latest patches - Refactor the code periodically - Write stateless code so that it would be easier in case of scalability

In my experience updating code in web applications is like fixing holes in a fence. Sometimes, new ways that bad guys can break in are discovered. By updating the code, we patch up those holes, making it harder for the bad guys to get in and keeping the web app safer for everyone to use

Security and Privacy: Identity for authentication and HTTPS for data security. Minimal data & Core Identity, comply with GDPR.

Secure File Handling: ASP.NET Core for secure file uploads. Incident Response: Azure Security Center for quick response. User Education: Include tooltips in the UI for security tips. Compliance and Accessibility: Azure Policy compliance & Application Insights.

Security and Privacy: 1. Web Application for backend Laravel, Which has inbuilt function middleware for authentication security and Cross-Site Request Forgery (CSRF) is an attack that forces authenticated users to submit a request to a Web application against which they are currently authenticated. CSRF attacks exploit the trust a Web application has in an authenticated user. 2. For frontend we can use HTML, CSS, JS, to make a website interactive and Frontend will be private. Means Backend we can use Laravel which is Php framework and Frontend for user friendly html ,css, js. Thanks

Session Management: Implement secure session management practices, including secure session storage, session timeout, and session token regeneration. Use secure and random session identifiers.

While secure development require knowledge of Encryptions and Data Signing Standards in data transit, I also give equal importance in maintaining Shift-Left approach in SDLC While writing Single-Page-Web Application to ensure easy-to-use UX and security, Always start with writing frontend flow in router rendered view and dummy data-store: First, Define user roles. Then, Define modules separated by router the application can be dissected in. Then, Document access boundary of modules against user roles including ACCESS VIOLATION semantics(Code and messages). Finally, implement the flow maintaining TDD, revisit in iterations while developing backend.

Whatever you do ensure you have a restorable backup of your data/code/build/documentation/site (including DevOps artifacts). The best place for this is in the cloud protected by multiple Azure/AWS data centres. If you have no backup, all the data/code has to be recreated from scratch and this may not be possible. It is best to keep as much as possible away from the office. Use Microsoft 365 as SAAS for business software and Microsoft Accounts for authentication as widely supported in cloud. Minimize 3rd party software usage as this requires continuous maintenance often overlooked (eg scanning for vulnerabilities etc). Licensors have their own roadmaps and may remove support when fitting in annual updates is too hard (eg work with.NET 8)
