Web application testing

Testing plays a very important role in ensuring security and robustness of web applications. Various approaches – from high level auditing through penetration testing to ethical hacking – can be applied to find vulnerabilities of different types. However if you want to go beyond the easy-to-find low-hanging fruits, security testing should be well planned and properly executed. Remember: security testers should ideally find all bugs to protect a system, while for adversaries it is enough to find one exploitable vulnerability to penetrate into it.


Web application testers 


Preparedness: Basic Web application developers and testers 

Course outline:

Attending this course will prepare software testers to adequately plan and precisely execute security tests, select and use the most appropriate tools and techniques to find even hidden security flaws. Practical exercises will help understanding web application vulnerabilities and mitigation techniques, together with hands-on trials of various testing tools from security scanners, through sniffers, proxy servers, fuzzing tools to static source code analyzers, this course gives the essential practical skills that can be applied on the next day at the workplace.

  • Topics include
    security auditing, security testing vs. penetration tests and ethical hacking; threat modeling and risk analysis; STRIDE classification: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege; OWASP top 10 vulnerabilities, SQL Injection and similar flaws, Cross-site Scripting (XSS), Cross-site Request Forgery (CSRF); organized process of internet attacks: IP/port scanning, zero day exploits, virus infections, bot-nets, spamming, phishing, vishing, distributed denial-of-service (DoS) attacks, internet bank frauds; Web application security testing: white-box, black-box and grey-box testing; structured code review, validating implemented mitigation techniques, checking for misconfigurations; Tools and methods: security scanners (Nikto/Wikto, Nessus, Netsparker), SQL injection tools (SqlMap, SqlNinja, Safe3 SQL Injector), knowledge sources (CVE, NVD, BSI, SHIELDS), Metasploit penetration testing resources, finding security holes (Google hacking, SiteDigger, FSDB, GHDB), sniffers (Tcpdump, Ngrep, Wireshark), proxy servers (BurpSuite, Paros proxy), fuzzing robustness and security testing tools, static source code analyzers (FlawFinder, FindBugs, RIPS, Pixy, Fortify)
  • Exercises:
    S exploiting SQL injection step-by-step; crafting Cross-Site Scripting attacks through both reflective and persistent XSS; committing Cross-Site Request Forgery (CSRF); malicious file execution; insecure direct object reference; uploading and running executable code; cracking hashed values with search engines; information leakage through error reporting; using security testing tools: crafting fuzz-testing, using the NetSparker Web vulnerability scanner, using Safe3 SQL Injector to automate injection flaw exploit, understanding vulnerability databases and working with exploit collections, google hacking exercise, using SiteDigger, sniffing network traffic with WireShark and the Burp Suite proxy, using the FindBugs source code analyzer.
