## Introduction
## Introduction to Security Practices
This guide covers the best practices for securing WooCommerce stores, including hardening WordPress, keeping plugins and themes up to date, implementing secure coding practices, and protecting user data. By following these recommendations, developers can build secure and resilient WooCommerce stores that protect both their business and their customers.
Security is extremely important for online stores. A breach can lead to significant financial loss, reputational damage, and erosion of customer trust. Implementing robust security practices is crucial. This guide covers the best practices for securing WooCommerce stores, including hardening WordPress, keeping plugins and themes up to date, implementing secure coding practices, and protecting user data. By following these recommendations, developers can build secure and resilient WooCommerce stores that protect both their business and their customers.
## Audience
### Audience
This guide is intended for developers who are familiar with WordPress and WooCommerce and want to improve the security of their online stores.
## Prerequisites
### Prerequisites
To follow this guide, you should have:
1. A basic understanding of WordPress and WooCommerce.
2. Access to a WordPress website with WooCommerce installed and activated.
## Step 1 - Keep WordPress, WooCommerce, and plugins up to date
## Security Standards
We recommend that you maintain the following standards:
- **PHPCS**: The PHP Code Sniffer tool helps ensure your code adheres to specific coding standards, which can prevent common security issues. Extensions shouldn't have any failure results against PHPCS.
- **SemGrep**: Focuses on identifying patterns that may indicate security vulnerabilities, allowing developers to write more secure code. Extensions shouldn't have any failure results against SemGrep.
Understanding and implementing these standards can significantly reduce the risk of security vulnerabilities in your extensions and themes.
### Common Security Pitfalls and How to Avoid Them
Several common security pitfalls can easily be avoided with vigilance and best practices:
- **SQL Injection**: Ensure all database queries are properly sanitized.
- **Cross-Site Scripting**: Sanitize all user input to prevent malicious code from being executed.
- **File Inclusions**: Limit file inclusion to prevent unauthorized access to the file system.
Awareness and prevention of these common issues are crucial steps in securing your WooCommerce store. For more resources, we recommend reading the [WordPress security documentation](https://developer.wordpress.org/apis/security/).
## Manual Testing Guidelines
Even without access to automated tools like the [Woo Quality Insights Toolkit (QIT)](https://qit.woo.com), manual testing remains a vital component of securing your WooCommerce store. Here are some guidelines on how developers can manually test their extensions for security vulnerabilities:
1. **Code Review**: Regularly review your code for security vulnerabilities, focusing on the areas where breaches commonly occur, such as user input fields and database queries. Code reviews should check against the [WordPress security criteria](https://developer.wordpress.org/apis/security/) mentioned above.
2. **Use Security Plugins**: Plugins like Wordfence, Sucuri, or iThemes Security provide an interface for manual security checks, including file integrity monitoring and malware scanning. Additionally, tooling like [OWASP Zap](https://www.zaproxy.org/) or [GitHub Security Scanning](https://github.com/features/security/) can be used.
3. **Testing Environments**: Utilize staging environments to test the security of new features or updates before deploying them live.
## Other Security Best Practices
### Keep WordPress, WooCommerce, and plugins up to date
Regularly updating WordPress, WooCommerce, and all installed plugins is crucial to maintaining a secure online store. Updates often include security patches that address vulnerabilities and help protect your store from attacks. To keep your WordPress and WooCommerce installations up to date:
