OWASP Top 10 is a list of the most common web vulnerabilities. Knowing these helps prevent serious attacks.
- SQL Injection – Malicious queries into databases
- XSS – Injecting scripts into websites
- Broken Authentication – Weak login protection
- Security Misconfiguration – Leaving default settings
- Sensitive Data Exposure – Not encrypting important data
Example:
If a login page allows SQL Injection, an attacker can bypass passwords and log in as any user.
