PHP 8 Web Security training helps developers and IT professionals build safer web applications by identifying and preventing common security vulnerabilities. Participants will learn practical techniques for protecting PHP applications against XSS, SQL injection, CSRF, session attacks, and other threats while applying secure coding and web security best practices.
Duration 5 days – 35 hrs
Overview
As organizations increasingly rely on PHP for web application development, ensuring the security of these applications becomes paramount. The PHP 8 Web Application Security Training course is designed to equip developers, security professionals, and system administrators with the knowledge and skills necessary to build and maintain secure PHP web applications.
Web applications are under attack every day. PHP, being one of the most widely-used programming languages on the web, is one of the main targets. Some oddities, especially those of older versions, facilitate some of the attacks. This course, PHP Web Application Security, helps developers to understand security risks, how vulnerabilities can be exploited, and how to avoid those attacks. First you’ll learn about how to defend against cross-site scripting, including new approaches such as content security policy. Next, you’ll learn about how cross-site request forgery works, why it works so well, and how you can implement protection using PHP.
