npx create-strapi-app my-project` command is used to create a new Strapi project, allowing developers to build their application backend and frontend platforms using Restful APIs and GraphQL. API security is critical in protecting customer data, and Strapi provides features such as role-based access control, audit logging, and secure authentication to prevent unauthorized access. To secure the front end of your Strapi application, you can configure CORS and use HTTPS, and implement robust security measures such as authentication, authorization, input validation, and regular updates to ensure the security of your APIs in Strapi.
