About

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?
  • 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?

What Can You Learn Here?

  • What is the fastest way to secure my legacy PHP application?
  • What options do I need in my php.ini file for security?
  • What is the proper way to sanitize data in 2019 with PHP?
  • How can I check my dependencies for vulnerabilities?
  • How do you secure the web server running the PHP code?
  • How does one secure phpmyadmin, MySQL, and Postgres databases?
  • How can you harden your WordPress or Drupal site?

It is not easy to produce a PHP application without security vulnerabilities. Most application security vulnerabilities apply to PHP applications just like other environments.

The goals of this project are to provide information about building, configuring, deploying, operating, and maintaining secure PHP applications

PHP Security for Developers

This section will also cover standard security mechanisms available in the standard language, such as cryptography, logging, encryption, and error handling. Securing elements of an application, such as controllers, business logic, and persistence layers will be covered. We'll discuss handling request parameters, encoding, injection, and more.
