OWASP Top 10: The Most Critical Web Application Security Risks

As we continue to rely more and more on web applications in our daily lives, it's crucial to be aware of the potential security risks that come with them. That's where the OWASP Top 10 comes in - a list of the most critical web application security risks compiled by the Open Web Application Security Project.


  1. Injection: This refers to the insertion of malicious code into a web application, often through user input fields like login forms.

  2. Broken Authentication and Session Management: Weaknesses in authentication and session management can allow attackers to gain access to user accounts and sensitive data.

  3. Cross-Site Scripting (XSS): This occurs when attackers inject malicious scripts into otherwise legitimate web pages, which can then execute in users' browsers.

  4. Broken Access Controls: If web applications don't properly restrict access to sensitive data or functionality, attackers can exploit this weakness to gain unauthorized access.

  5. Security Misconfiguration: This refers to any insecure configuration of web applications, servers, or other components, such as default passwords or unnecessary features.

  6. Insecure Cryptographic Storage: If sensitive data is not properly encrypted or hashed, attackers can potentially gain access to it.

  7. Insufficient Transport Layer Protection: This refers to weaknesses in the encryption and protection of data as it is transmitted between a web application and its users.

  8. Insufficient Logging and Monitoring: Without proper logging and monitoring, it can be difficult to detect and respond to security incidents.

  9. Insecure Communications: This includes any use of insecure protocols or channels to transmit sensitive data, such as sending passwords over unencrypted email.

  10. Using Components with Known Vulnerabilities: If web applications use third-party components with known vulnerabilities, attackers can exploit these weaknesses to gain access to the application or its data.


By staying informed about these potential risks and taking steps to prevent them, we can help keep our web applications and data safe and secure. Stay vigilant! 🔒👀
