== About ==
 
== About ==
  
The OWASP PHP Technology Knowledge Base is the clearing house for all information related to building secure web applications and services based on PHP technologies. The focus of the project is on guidance for developers and application architects on using PHP and PHP frameworks. Moreover, we aim to provide security related guidance for system administrators managing PHP based applications and tools.
+
There are 1.8 billion websites on the internet today. Nearly 80% are powered by the PHP programming language. Freedom, privacy, security, and protection from totalitarianism are not possible if PHP is insecure. This project seeks to be the clearing house for the best ways of protecting PHP websites, apps, and the data they have. Thank you for reading.
 +
  
Community content is key to security information. The project depends on content from developers throughout the PHP ecosystem.
+
== What Does PHP Security Mean? ==
  
==Purpose==
+
* CONFIG: Is my configuration secure? E.g. am I using the latest version of PHP? How does my PHP.ini file look?
 +
* CODEBASE: Is my codebase secure? Am I protecting against SQL injection? Am I protecting against stored XSS attacks?
 +
* ARCHITECTURE: is the app designed with security in-mind? Do I have good documentation on securing the app? Do I have brute force protection or MFA as available options?
 +
* INFRASTRUCTURE: is my deployment environment secure? E.g. Have I hardened the web server the application runs on?
 +
* DEVELOPMENT: Is my development infrastructure secure? E.g. Do I have 2FA on my Github account along with all other developers?
  
* Provide deep, rich guidance for PHP developers in using the security features of PHP and of PHP frameworks.
+
== What Can You Learn Here? ==
* Address security in relation to PHP and derived technologies.
+
* What is the fastest way to secure my legacy PHP application?
* Guide system administrators in managing PHP related components and applications.
+
* What options do I need in my php.ini file for security?
* Create guidance for use of OWASP components that are designed for use with PHP.
+
* What is the proper way to sanitize data in 2019 with PHP?
* Focus on information about working with and on OWASP tools built using PHP or other PHP technologies.
+
* How can I check my dependencies for vulnerabilities?
* Provide a stream of security related information, like vulnerabilities and security patches, related to the PHP universe.
+
* How do you secure the web server running the PHP code?
* Build an ecosystem allowing to all actors interested to discuss, share and learn.
+
* How does one secure phpmyadmin, MySQL, and Postgres databases?
 +
* How can you harden your WordPress or Drupal site?
 +

There are 1.8 billion websites on the internet today. Nearly 80% are powered by the PHP programming language. Freedom, privacy, security, and protection from totalitarianism are not possible if PHP is insecure. This project seeks to be the clearing house for the best ways of protecting PHP websites, apps, and the data they have. Thank you for reading. ​

What Does PHP Security Mean?

  • CONFIG: Is my configuration secure? E.g. am I using the latest version of PHP? How does my PHP.ini file look?
  • CODEBASE: Is my codebase secure? Am I protecting against SQL injection? Am I protecting against stored XSS attacks?
  • ARCHITECTURE: is the app designed with security in-mind? Do I have good documentation on securing the app? Do I have brute force protection or MFA as available options?
