Can I use this for securing user logins?

Absolutely. It covers secure password hashing using modern PHP algorithms and provides patterns for secure session handling.

How does this skill help prevent SQL injection?

It guides developers to use PDO prepared statements and parameter binding, ensuring user input is never directly interpolated into SQL queries.

Does it provide patterns for XSS protection?

Yes, it includes specialized functions for HTML, JavaScript, and URL attribute escaping to prevent malicious script injection.

Is this skill relevant for PHP frameworks like Laravel or Symfony?

While frameworks have built-in security, this skill provides the foundational knowledge and custom patterns necessary for building secure extensions or working in vanilla PHP environments.

What is meant by defense-in-depth in this skill?

It refers to implementing multiple layers of security, such as combining input validation, output encoding, and server-side configurations like Content Security Policies.

セキュリティとテスト

Implements industry-standard security patterns and defense-in-depth strategies to safeguard PHP applications against common vulnerabilities.

概要

This skill equips Claude with specialized knowledge to identify and mitigate critical PHP security risks. It provides implementation patterns for input validation, SQL injection prevention using PDO prepared statements, cross-site scripting (XSS) protection through context-aware encoding, and secure session management. By integrating these professional security practices, developers can build robust, ethical, and resilient PHP applications that protect user data and maintain system integrity.
