# Vulnerability Scanning Most generic scanners struggle to detect vulnerabilities specific to APIs, especially those listed in the OWASP API Security Top 10. However, they can be effective at identifying [Security Misconfigurations ](https://owasp.org/API-Security/editions/2019/en/0xa7-security-misconfiguration/)like: * Missing patches * Unnecessary features * Lack of secure encryption * Weak security headers * CORS misconfigurations #### **Scanning with Nikto** * To see how a generic scan can fail, try scanning with **Nikto** using this command: ```bash nikto -h http://example.com ``` While Nikto may reveal server information and some security headers issues, it typically misses a broad range of API vulnerabilities. #### **Using OWASP ZAP for Better Results** Switching to **OWASP ZAP** allows for a more customized approach to API scanning. Start with an unauthenticated scan by importing the API specification file (`specs.yml`) for your target, then run an **Active Scan** on the root URL. Check the **Alerts** tab for security misconfiguration findings. **Performing Authenticated Scans** To get deeper insights, conduct an **authenticated scan**. Use the **Manual Explore** feature in ZAP to interact with the application as a user, after logging in and performing actions, run another **active scan**. This process often uncovers more vulnerabilities than the initial scan. then Review the scan results to differentiate between actual vulnerabilities and false positives --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://ahmed-tarek.gitbook.io/security-notes/notes/api-pen/vulnerability-scanning.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
