OWASP Security Scan Details
HostedScan provides two OWASP security scans to meet the needs of every user. Both scans use the OWASP ZAP (Zaproxy) scanner, a leading open source project used by many large players in the security industry.
These scans test websites and web apps for OWASP Top 10 risks and more. ZAP is the industry-standard open-source dynamic application security testing tool trusted by security teams worldwide, covering SQL injection, XSS, and dozens of other vulnerability classes. No installation needed.
The Passive Scan
Loads the pages of a website and checks for vulnerabilities such as cross-domain misconfigurations, insecure cookies, and vulnerable JS dependencies.
Fast: Completes within several minutes
Safe: Non-intrusive scanning method
Complete: Checks configuration and informational issues
The Active Scan
Submits forms and makes requests to the web application to test for vulnerabilities such as SQL injection, remote command execution, and cross-site scripting.
Extensive: Thorough testing of all vulnerabilities
Permission Required: Make sure you have authorization
Thorough: May take several hours for complete coverage
OWASP ZAP detects hundreds of vulnerabilities. Here are the most common ones for widely-used web technologies.
From hundreds of scan capabilities in the feed, these are the ones that show up most in real-world scans.
