2 Agenda About Web Vulnerability Assessments Tools Demos Goals Types SOW
Steps Tools Demos Goals Demonstrate Web VA, show techniques Pen-testers and Hackers use to find vulnerabilities in your sites Provide some techniques and tools to help secure your code

6 Web Vulnerability Assessments
Conducted against a contract with specific terms, most often called the Statement of Work (SOW) Specify in the SOW: System to be tested (URL) Production or Non-Prod? Type and level of testing Level of Automated and Manual testing “Safe” Tests only? Hours for testing Nights only? Whitelist IP addresses in WAF, IPS? Special Concerns? The more information the better the assessment Additional considerations: Number of user roles, whether retesting is included, if non-prod, will travel be involved.

7 Web Vulnerability Assessments
Types of Application Security Testing: Dynamic Analysis Security Testing (DAST) “Black Box” Tests actual web site for vulnerabilities Simulates what a real attacker would do Static Analysis Security Testing (SAST) “White Box” Tests code for vulnerabilities A real attacker would likely not have access to the code, this method is a different approach to identifying potential security flaws. Hybrid “Glass Box” Dynamic test against instrumented web server Manual testing can occur in each type Talk covers Dynamic Testing Some tools perform static analysis of JavaScript

8 “Typical” Web Assessment Steps
Recon Site components and architecture Open ports? Hack the server Manually crawl site with an Intercepting Proxy Automated Scan of site Results verification – False positives removal Manual testing Things tools don’t do well Business Logic Privilege Escalation etc. Reporting

9 Recon Visit site Site information Google Dorks Port Scan
Netcraft, Shodan etc. Google Dorks Files, passwords, WSDL, Admin logons etc. Port Scan Nmap, Nessus, Qualys May perform an infrastrucuture vulnerability scan Missing patches, configuration issues etc. Check security configuration

10 Configuration Checkers
Microsoft Web Application Configuration Analyzer Needs Admin on Server, Checks SQL Server too Check Your Headers SSL Labs https://www.ssllabs.com/ssltest/index.html ASAFAWEB https://asafaweb.com/

11 Crawl Site with Intercepting Proxies
Burp* Fiddler Zed Attack Proxy (ZAP) https://code.google.com/p/zaproxy/wiki/Downloads * - Free and Professional versions

12 Intercepting Proxy Intercepting Proxy Man-in-the-Middles all traffic
Hackers and Testers can see all data transmitted Hidden Fields => NOT a security feature

13 Burp

14 Burp – Analyze Request & Response

15 Scan Site – Dynamic Scanners
Acunetix AppScan WebInspect Burp & ZAP have scanning modules

16 AppScan
