Web Application Security Guide

Web applications are critical targets for cybercriminals. Understanding common vulnerabilities and how to defend against them is essential for developers and security professionals.

OWASP Top 10 (2023)

The Open Web Application Security Project (OWASP) identifies the ten most critical security risks to web applications.

1. Broken Access Control

Failing to enforce user permissions allows attackers to access unauthorized resources.

2. Cryptographic Failures

Insecure handling of sensitive data in transit or at rest leads to exposure.

3. Injection Attacks

SQL injection, command injection, and other injection attacks allow attackers to manipulate application logic.

4. Insecure Design

Missing security controls and failure to apply security principles during design.

5. Security Misconfiguration

Incorrectly configured security settings in frameworks, databases, and servers.

6. Vulnerable and Outdated Components

Using libraries and dependencies with known vulnerabilities.

7. Authentication Failures

Weak password policies, session management issues, and lack of MFA.

8. Software and Data Integrity Failures

Insecure CI/CD pipelines and unsafe deserialization.

9. Logging and Monitoring Failures

Inadequate logging prevents detection of attacks and incident response.

10. Server-Side Request Forgery (SSRF)

Allowing applications to make requests to unintended locations.

Common Vulnerabilities

SQL Injection: Attackers inject SQL code into input fields to manipulate databases.

Cross-Site Scripting (XSS): Malicious scripts are injected and executed in user browsers.

Cross-Site Request Forgery (CSRF): Attackers trick users into performing unintended actions.

Path Traversal: Unauthorized access to files outside intended directories.

Defense Best Practices

Conclusion

Web application security requires a comprehensive approach combining secure coding, proper architecture, and continuous security testing.
