Security in Composable Commerce

1. Introduction

Composable commerce leverages a headless architecture, enabling businesses to create tailored eCommerce solutions. However, with flexibility comes increased security risks. This lesson details the security considerations for composable commerce systems.

2. Key Concepts

• **Headless Commerce**: Separation of the frontend and backend, allowing for greater customization and flexibility.
• **Composable Architecture**: Building systems using modular components that can be independently developed, updated, and replaced.
• **API Security**: Protecting the APIs that connect various components in a composable commerce system.

3. Security Challenges

Composable commerce introduces several security challenges:

• **Increased Attack Surface**: More components mean more potential vulnerabilities.
• **Data Privacy**: Handling sensitive customer data securely.
• **Authentication and Authorization**: Ensuring that only authorized users can access specific resources.

4. Best Practices

To mitigate security risks, consider the following best practices:

1. **Implement API Security**: Use OAuth for authentication and HTTPS for secure communication.
2. **Data Encryption**: Encrypt sensitive data both in transit and at rest.
3. **Regular Security Audits**: Conduct regular assessments of your system to identify and address vulnerabilities.
4. **Use a Web Application Firewall (WAF)**: Protect your APIs from common web exploits.
5. **Monitor and Log Activities**: Keep an eye on unusual activities and maintain logs for auditing purposes.

5. Code Examples

Here's a basic example of how to implement API authentication using JWT (JSON Web Tokens):

                const jwt = require('jsonwebtoken');

                // Function to generate a token
                function generateToken(user) {
                    return jwt.sign({ id: user.id }, 'your_secret_key', { expiresIn: '1h' });
                }

                // Middleware to verify token
                function authenticateToken(req, res, next) {
                    const token = req.headers['authorization'];
                    if (!token) return res.sendStatus(401);
                    jwt.verify(token, 'your_secret_key', (err, user) => {
                        if (err) return res.sendStatus(403);
                        req.user = user;
                        next();
                    });
                }
