OWASP Top Ten Security Risks
- 1. Broken Access Control - Improper enforcement of permissions.
- 2. Cryptographic Failures - Weak encryption or data exposure.
- 3. Injection Attacks - SQL injection and command injection.
- 4. Insecure Design - Flaws in application architecture.
- 5. Security Misconfiguration - Default settings or unpatched vulnerabilities.
- 6. Vulnerable and Outdated Components - Using obsolete libraries and dependencies.
- 7. Identification and Authentication Failures - Weak login mechanisms.
- 8. Software and Data Integrity Failures - Compromised software updates.
- 9. Security Logging and Monitoring Failures - Lack of auditing.
- 10. Server-Side Request Forgery (SSRF) - Exploiting backend requests.

Injection Attacks
Injection vulnerabilities allow attackers to execute malicious commands.
sqlmap -u 'http://target.com?id=1' --dbs5
Broken Access Control
Improper permissions can allow attackers to access restricted resources.
6
Security Misconfiguration
Default credentials, unnecessary services, and exposed admin panels can lead to breaches.
7
Preventing OWASP Risks
- Use input validation and sanitization.
- Implement strong authentication.
- Apply security patches regularly.
- Use web application firewalls (WAF).
