17.4 From HTTP and Web Servers to Burp Suite, Nikto and Misconfigurations

| You learnt (Parts 3, 4, 6) | You will use it for |
|---|---|
| HTTP methods, headers, status codes | Reading and editing requests in Burp Suite and OWASP ZAP |
| Cookies and sessions | Session hijacking concepts, testing HttpOnly/Secure flags |
| Nginx/Apache document root, config | Finding exposed files (.git, backups) with Gobuster/Dirb; fixing them in config |
Virtual hosts and the Host header |
Virtual host discovery, Host-header attacks |
| PHP forms and file upload | File upload and command injection tests in DVWA |
| TLS and Certbot | Testing weak protocols, missing HSTS |
| DNS and subdomains | Recon: subdomain enumeration, dangling DNS records |
curl -sI https://yourdomain.com | grep -Ei 'server|x-powered-by|strict|content-security'
That one line already tells a tester (and you) whether versions leak and whether security headers exist – no special tool needed.
Why this matters for security
A large share of real web findings are security misconfiguration (सुरक्षा चुकीचे कॉन्फिगरेशन): directory listing, default pages, verbose errors, missing headers, exposed admin panels. You configured all of these yourself in Parts 3 and 6, so you know both how they happen and how to fix them in one line of config.
Ravindra Bagale's Tip
When students open Burp Suite for the first time, all the tabs and buttons scare them. Don't worry – Burp just shows HTTP requests and responses, which we've already seen with curl -v. First learn to read requests with curl -v, and then Burp will feel very simple.
Ravindra Bagale's Tip – मराठी
Burp Suite पहिल्यांदा उघडल्यावर students ना खूप tabs आणि buttons बघून भीती वाटते. घाबरू नका – Burp फक्त HTTP request आणि response दाखवतो, जे आपण curl -v ने आधीच बघितले. आधी curl -v ने request वाचायला शिका, मग Burp एकदम simple वाटेल.
Ravindra Bagale's Tip – हिंदी
Burp Suite पहली बार खोलने पर बहुत सारे tabs और buttons देखकर students डर जाते हैं. घबराओ मत – Burp बस HTTP request और response दिखाता है, जो हम curl -v से पहले ही देख चुके हैं. पहले curl -v से request पढ़ना सीखो, फिर Burp बहुत आसान लगेगा.
Practice task
Run curl -v https://yourdomain.com and label every line: request line, request headers, status line, response headers. Then list three response headers that would interest a security tester.
