Ethical Hacking Examples: Web Application Vulnerability Case Studies

📚 Quick Study Guide

• 🔍 Web application vulnerabilities are weaknesses in web apps that can be exploited by attackers.
• 🛡️ Ethical hacking involves identifying and mitigating these vulnerabilities before malicious actors can exploit them.
• 🕸️ Common vulnerabilities include SQL injection, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF).
• 🔑 Authentication and authorization flaws can allow unauthorized access to sensitive data.
• ⚠️ Regular security testing and code reviews are crucial for identifying and addressing vulnerabilities.
