Day 32 – OWASP Top 10 Overview | Complete Guide
🛡 Day 32 – OWASP Top 10 Overview (Complete Guide)
Agar aap Bug Hunting ya Web Security seekh rahe ho, to ek cheez clear honi chahiye:
Duniya ki sabse common web vulnerabilities kaun si hain?
Iska jawab milta hai OWASP Top 10 me.
Ye sirf ek list nahi hai —
ye security world ka standard reference framework hai.
🌍 OWASP Kya Hai?
OWASP (Open Web Application Security Project) ek global non-profit organization hai jo web security awareness aur research karti hai.
OWASP:
✔ Free security documentation provide karta hai
✔ Security tools banata hai
✔ Developers ko secure coding sikhata hai
✔ Top vulnerabilities ki list publish karta hai
📊 OWASP Top 10 Kya Hai?
OWASP Top 10 ek list hai jo batati hai:
Web applications me sabse common aur dangerous security risks kaun se hain.
Latest popular version:
OWASP Top Ten
Ye list real-world data, security reports aur research ke basis par banayi jati hai.
🤔 OWASP Top 10 Important Kyu Hai?
Companies isi list ke basis par security test karti hain
Bug bounty programs me most bugs isi category ke milte hain
Interviews me frequently pucha jata hai
Ye beginners ke liye roadmap ka kaam karta hai
Agar aapko OWASP Top 10 strong hai → aapki security foundation strong hai.
🔟 OWASP Top 10 (2021) – Detailed Explanation
Ab hum har risk ko clearly samjhenge:
1️⃣ Broken Access Control
👉 Jab system properly check nahi karta ki user ko kis cheez ka access milna chahiye.
Example:
ID change karke dusre user ka data dekh lena
Normal user admin panel access kar le
Ye sabse common aur dangerous vulnerability hai.
2️⃣ Cryptographic Failures
👉 Jab sensitive data properly encrypt nahi kiya jata.
Example:
Password plain text me store ho
HTTPS use na ho
Isse data leak ka risk hota hai.
3️⃣ Injection
👉 Jab user input ko properly filter nahi kiya jata.
Types:
SQL Injection
Command Injection
LDAP Injection
Result:
Attacker database ya system commands manipulate kar sakta hai.
4️⃣ Insecure Design
👉 Application ka design hi insecure ho.
Example:
OTP expire na ho
Password reset me weak logic
Yaha problem coding se zyada planning me hoti hai.
5️⃣ Security Misconfiguration
👉 Server ya application galat configure ho.
Example:
Debug mode on rehna
Default passwords use karna
Admin panel publicly accessible hona
6️⃣ Vulnerable & Outdated Components
👉 Old libraries ya plugins use karna jisme known vulnerabilities ho.
Example:
Purana CMS plugin jisme already exploit available ho.
7️⃣ Identification & Authentication Failures
👉 Weak login system.
Example:
Unlimited login attempts
Weak password policy
Session properly expire na hona
8️⃣ Software & Data Integrity Failures
👉 Jab application untrusted updates ya code verify nahi karta.
Example:
Update files digitally sign na ho
Dependency tampering
9️⃣ Security Logging & Monitoring Failures
👉 Jab attack detect hi na ho.
Example:
Failed login attempts log na hona
Suspicious activity monitor na karna
Isse attacker long time tak unnoticed reh sakta hai.
🔟 Server-Side Request Forgery (SSRF)
👉 Jab attacker server ko internal resource se request bhejne par majboor kare.
Example:
Server internal IP access kar le user input ke through.
🧠 OWASP Top 10 Ko Kaise Use Kare?
Jab bhi website test karein:
✔ URL parameters check karein
✔ Access control test karein
✔ Input validation observe karein
✔ Authentication system analyze karein
✔ Server configuration errors dekhein
Har test ko OWASP Top 10 ke angle se dekhein.
🎯 Bug Hunter Strategy
Har vulnerability ko 4 core areas me divide karein:
Input related issues
Access control issues
Authentication issues
Configuration issues
Maximum real-world bugs inhi categories me milte hain.
🔁 Final Revision
OWASP ek global security organization hai
OWASP Top 10 common web risks ki list hai
2021 version widely accepted hai
Broken Access Control sabse common risk hai
Ye bug hunters ke liye roadmap jaisa hai
