What Is OWASP? And What Are The OWASP Top 10?

Cybersecurity attacks are rising. For that reason, it is important to use secure software practices to help safeguard your code against any vulnerabilities. Here, we explain what is OWASP and what are the OWASP Top 10 vulnerabilities.

What Is OWASP?

OWASP is the Open Web Application Security Project. It's an international nonprofit organization that educates software development teams on how to conceive, develop, acquire, operate, and maintain secure applications.

All of the organization's materials (which includes articles, methodologies, documentation, tools, and technologies) are freely available and easily accessible. These materials improve application security through people, process, and technology.

What Are The OWASP Top 10?

The OWASP Top 10 is the most well-known resource that the organization produces. Each year, a team of security experts from across the globe updates the report. This report features the 10 most critical web application and API security risks.

The current list includes:

  1. Injection
  2. Broken Authentication
  3. Sensitive Data Exposure
  4. XML External Entities (XXE)
  5. Broken Access Control
  6. Security Misconfiguration
  7. Cross-Site Scripting (XSS)
  8. Insecure Deserialization
  9. Using Components With Known Vulnerabilities
  10. Insufficient Logging and Monitoring

OWASP Top 10: A Closer Look

1. Injection

Injection flaws occur when untrusted data is sent as part of a command or query. The attack can then trick the targeted system into executing unintended commands. Or it could give the cybercriminal access to protected data.

2. Broken Authentication

Authentication is often implemented incorrectly. This enables cybercriminals to take advantage of security vulnerabilities. They can even gain access to users' identities.

3. Sensitive Data Exposure

Sensitive data is often not properly protected. This enables cybercriminals to easily take advantage of security vulnerabilities.

4. XML External Entities (XXE)

Older or poorly configured XML processors evaluate external entity references within XML documents. These external entities can be used by cybercriminals to gain access to sensitive information. They could even launch a denial of service attack.

5. Broken Access Control

User restrictions are often not properly enforced. This creates security vulnerabilities that cybercriminals can exploit.

6. Security Misconfiguration

Security misconfiguration is often a result of:

  • Insecure default configurations.
  • Incomplete or ad hoc configurations.
  • Open Cloud storage.
  • Misconfigured HTTP headers.
  • Verbose error messages that contain sensitive information.

7. Cross-Site Scripting (XSS)

Cross-site scripting flaws occur when an application includes untrusted data in a new webpage — without proper validation. It can also occur when an existing web page is updated with user-supplied data using a browser API that can create HTML or JavaScript. Cybercriminals take advantage of cross-site scripting to execute scripts in the targeted system.

8. Insecure Deserialization

Deserialization flaws often result in remote code execution. This enables cybercriminals to perform replay, injection, and privilege escalation attacks.

9. Using Components with Known Vulnerabilities

Components — such as libraries or frameworks — run the same privileges as the application. A vulnerable component can be exploited by a cybercriminal. This causes serious data loss or server takeover.

10. Insufficient Logging and Monitoring

Insufficient logging and monitoring can enable cybercriminals to attack systems. They can even tamper, extract, or destroy data.

Enforce Secure Software Best Practices

Here's one of the most important best practices. Implement secure coding practices to prevent vulnerabilities. More on SAST >>

Using a SAST tool — such as Klocwork — helps you enforce best practices.

This is an important part of the process of developing secure web applications. Using a tool like Klocwork helps you comply with security standards. That's because Klocwork automatically checks your code against the list of security weaknesses. It flags violations to help enforce secure coding guidelines. To make compliance easier, Klocwork provides security reports on the quality of your code.

How to Enforce OWASP With Static Code Analysis

The best way to ensure web application security is to use a static code analyzer.

Static code analyzers enforce coding rules and flag security violations. Klocwork comes with code security taxonomies to ensure secure, reliable, and efficient software.

Each one includes:

  • Fully documented rule enforcement and message interpretation.
  • Fully configurable rules processing.
  • Compliance reports for security audits.
