Frequently Asked Questions

Some common security vulnerabilities include cross-site scripting (XSS), cross-site request forgery (CSRF), SQL injection, insecure authentication and authorization, and insecure direct object references.

To prevent SQL injection attacks, ensure that you use parameterized queries and prepared statements when interacting with your database. This ensures that user input is escaped correctly and prevents it from being interpreted as SQL code.

While third-party libraries can provide additional functionality and save development time, evaluating their security and reliability is crucial. Only use well-maintained and regularly updated libraries from trusted sources. Keep them updated to address any known vulnerabilities.

To prevent XSS attacks, sanitize and validate all user input before rendering it in your application. Use libraries like DOMPurify to sanitize user-generated HTML content and avoid using dangerous methods like dangerouslySetInnerHTML.

Implement secure authentication practices, such as using strong password hashing algorithms, enabling multi-factor authentication, and implementing session management techniques like JWT (JSON Web Tokens). Also, avoid storing sensitive information like passwords in plain text.

Regularly update your application's dependencies, including security patches and bug fixes. Use dependency scanning tools and services to detect any known vulnerabilities in your dependencies and take appropriate actions to resolve them.

To prevent CSRF attacks, ensure that you use anti-CSRF tokens (or CSRF tokens) in your forms and requests to validate that the request originates from your application and not from a malicious source. Implement proper CSRF protection mechanisms, such as double-submit cookies or adding custom headers to validate requests.

HTTPS ensures secure communication between the client (browser) and the server by encrypting the data exchanged. It prevents eavesdropping and data tampering and ensures the integrity and confidentiality of sensitive information.

Client-side validation is a good practice for improving user experience and reducing unnecessary requests to the server. However, it should always be accompanied by server-side validation to ensure the integrity and security of data.
