OWASP Top 10: Protect Your Business from Web Risks

Web applications are the backbone of modern business — from customer portals and e-commerce platforms to internal business tools. But with this reliance comes risk. Cybercriminals continuously exploit vulnerabilities in applications to steal data, disrupt operations, and damage reputations.

To help organizations prioritize defenses, the Open Web Application Security Project (OWASP) has identified the Top 10 most critical web application security risks. Understanding these risks — and how to mitigate them — is essential for any business that relies on digital systems.

1. Injection Attacks: Malicious Code Entry

Injection attacks occur when attackers insert malicious code into input fields, such as login forms or URLs. If the input isn’t validated, this code can bypass authentication, manipulate data, or even steal sensitive information.

Solution: Use prepared statements, validate user input, and sanitize data before processing.

2. Broken Authentication: Unauthorized Access

Weak authentication mechanisms allow attackers to hijack accounts or escalate privileges. Common issues include weak passwords, poor session management, and missing multi-factor authentication (MFA).

Solution: Implement MFA, enforce strong password policies, and ensure secure session handling.

3. XML External Entities (XXE): Exploiting XML Vulnerabilities

Applications that process untrusted XML input can be exploited through XXE attacks. These attacks may grant access to internal files or allow remote code execution.

Solution: Disable external entity processing in XML parsers and sanitize all XML inputs.

4. Broken Access Control: Unauthorized Data Access

When access controls aren’t properly enforced, attackers can bypass restrictions to view, modify, or delete sensitive data. This remains one of the most common — and dangerous — risks.

Solution: Implement role-based access control (RBAC), enforce least privilege, and validate permissions for every request.

5. Security Misconfiguration: Easy Targets for Hackers

Default settings, exposed directories, and unnecessary features leave systems vulnerable. Misconfigurations often result in full system compromise.

Solution: Regularly patch software, remove unused features, and review security configurations.

6. Cross-Site Scripting (XSS): Malicious Script Injection

XSS occurs when attackers inject malicious JavaScript into user input fields. These scripts can steal credentials, session tokens, or modify website content.

Solution: Apply strict input sanitization and output encoding to prevent execution of untrusted scripts.

7. Using Components with Known Vulnerabilities

Applications often rely on third-party libraries and software components. If these are outdated or unpatched, attackers can exploit known vulnerabilities to gain access.

Solution: Keep all components up to date, apply security patches promptly, and monitor for advisories.

8. Insufficient Logging and Monitoring: Missing the Red Flags

Without proper logging, malicious activity often goes undetected. This allows attackers to operate for weeks or months without discovery, increasing the damage caused.

Solution: Implement real-time logging, monitoring, and alerting systems to identify suspicious activity early.

Why the OWASP Top 10 Matters for Your Business

The OWASP Top 10 isn’t just a technical checklist — it’s a blueprint for building resilient, secure applications. These risks highlight where attackers are most likely to strike, helping organizations prioritize resources and focus on the vulnerabilities that matter most.

Failing to address them can lead to devastating outcomes: data breaches, regulatory fines, financial losses, and long-term reputational damage. On the other hand, proactive security measures build trust with customers and position your business as a responsible steward of sensitive data.

Final Thoughts

The OWASP Top 10 is a reminder that cybersecurity is not optional — it’s foundational. Whether you’re developing applications in-house or relying on third-party vendors, addressing these vulnerabilities must be part of your core security strategy.
