How do I study owasp top 10 risks?

# Understand the Core Web Security Risks Visit the official OWASP Top 10 2025 page and review each risk: - **A01: Broken Access Control**: Failures allowing unauthorized access. - **A02: Security Misconfiguration**: Improper setups exposing systems. - **A03: Software Supply Chain Failures**: Compromised third-party components. 85 Take notes on real-world examples for each. Watch an intro video for context. 20

How do I set up local lab environment?

# Build a Safe Practice Playground 1. Download and install Burp Suite Community Edition from the official site. 74 2. Install Docker Desktop (free). 3. Pull and run OWASP WebGoat: `docker run -p 8080:8080 -p 9090:9090 --name webgoat webgoat/webgoat`. 73 4. Alternatively, clone DVWA: `git clone https://github.com/digininja/DVWA`, set up with XAMPP or PHP server. 56 Configure Burp as proxy in browser (127.0.0.1:8080).

How do I master traffic interception with burp?

# Learn Proxying and Manipulation 1. Launch Burp, configure proxy listener on 8080. 2. Browse vulnerable app (WebGoat/DVWA) through Burp proxy. 3. Use Repeater to modify requests (e.g., change parameters). 4. Inspect responses in Inspector. Practice tampering with cookies, headers. Refer to Burp docs for basics.

How do I practice core vulnerabilities?

# Exploit SQL Injection, XSS, and CSRF 1. Sign up at PortSwigger Web Security Academy (free). 84 2. Complete beginner labs: SQL injection (use Burp Repeater), XSS (reflected/DOM). 3. Solve 5-10 labs each, read theory sections. 4. Apply same payloads on local DVWA/WebGoat. **Example SQLi payload:** `' OR 1=1 --`

How do I apply testing methodology and review?

# Simulate Real Pentests 1. Download OWASP WSTG v4.2 PDF. 86 2. Pick a section (e.g., Injection Testing), apply to your lab apps. 3. Complete more PortSwigger labs on Access Control, SSRF. 4. Document findings in a report template: vuln, impact, fix. 5. Self-assess against OWASP Top 10.
