Testing Web Apps with OWASP ZAP: owasp-top-10 Security Quiz Quiz

Assess your understanding of using OWASP ZAP for web application security testing within the context of the OWASP Top 10 security risks. This quiz covers key concepts, methodologies, and best practices for identifying vulnerabilities with automated security tools.

1. Identifying Critical Security Risks

   When performing automated security testing using OWASP ZAP, which vulnerability from the OWASP Top 10 is most often detected through input field manipulation, as in trying to submit a login form with ' OR '1'='1?

   1. Injection
   2. Broken Encryption
   3. Insecure Logging
   4. Malformed Data

   Explanation: The correct answer is Injection, which refers to vulnerabilities such as SQL injection where untrusted data is sent to an interpreter as part of a command or query. Broken Encryption is incorrect because this risk relates to improper cryptographic controls, not direct input manipulation. Insecure Logging is unrelated to input field exploitation, instead dealing with improper storage of sensitive information. Malformed Data is not a recognized OWASP Top 10 risk and does not specifically address security vulnerabilities through form input.

2. Understanding ZAP's Active Scanning Process

   During a security test with OWASP ZAP, which stage involves intentionally sending crafted requests to uncover security flaws such as XSS in a comment section?

   1. Active Scanning
   2. Passive Monitoring
   3. Traffic Encryption
   4. User Enumeration

   Explanation: Active Scanning means sending tailored requests to a web application to provoke responses that can reveal vulnerabilities such as cross-site scripting. Passive Monitoring only observes existing requests and responses without altering them, so it cannot discover flaws requiring input manipulation. Traffic Encryption refers to protecting data in transit, not finding vulnerabilities. User Enumeration is a technique to discover valid usernames, not a scanning phase.

3. Prioritizing Vulnerabilities Found by ZAP

   If OWASP ZAP flags sensitive data being transmitted in URL parameters during checkout, which OWASP Top 10 risk does this behavior most closely represent?

   1. Sensitive Data Exposure
   2. Broken Access Control
   3. Insufficient Logging
   4. Code Injection

   Explanation: Sensitive Data Exposure covers cases where private information, such as personal or financial details, is not properly protected and may be visible in URLs. Broken Access Control relates to unauthorized actions, not the exposure of sensitive info. Insufficient Logging is about failing to properly record events and alerts, not data transmission. Code Injection involves injecting executable code, which is unrelated to this scenario.

4. Interpreting Passive Scan Results

   After running a passive scan, OWASP ZAP reports missing HTTP security headers. This finding primarily relates to which OWASP Top 10 risk if the site becomes susceptible to attacks like clickjacking?

   1. Security Misconfiguration
   2. Server Timeout
   3. Resource Mismanagement
   4. Cipher Block Chaining

   Explanation: Security Misconfiguration includes missing HTTP headers that help prevent attacks such as clickjacking or content sniffing. Server Timeout is not a security issue but a performance one. Resource Mismanagement doesn't directly cover misconfigured security settings. Cipher Block Chaining is a cryptographic method and not itself an OWASP Top 10 risk.

5. Managing Findings Efficiently

   When using OWASP ZAP to test a registration page and multiple issues relating to user session management are flagged, which best describes the recommended immediate next step?

   1. Review and prioritize the findings based on risk level
   2. Re-run only the passive scan multiple times for confirmation
   3. Delete all reports to start a fresh scan
   4. Publicly disclose the vulnerabilities before notifying stakeholders

   Explanation: The best practice is to review and prioritize the identified issues, addressing those with the highest security risk first. Re-running passive scans repeatedly is unlikely to yield new results without changes. Deleting reports unnecessarily discards valuable findings. Public disclosure before notifying stakeholders may cause harm and violates responsible disclosure principles.
