## **2. Installation and Configuration**
### **Installation Methods**
```bash
# Linux
wget https://portswigger.net/burp/releases/download?product=pro -O burpsuite_pro.sh
chmod +x burpsuite_pro.sh
./burpsuite_pro.sh
# Windows
Directly download and run the installer
```
### **Initial Setup**
1. Configure browser proxy: 127.0.0.1:8080
2. Install CA certificate (required for HTTPS decryption)
3. Set project scope and target domains
## **3. Detailed Explanation of Core Modules**
### **Proxy**
- **Request Interception**: Real-time viewing and modification of HTTP traffic
- **History**: Stores all requests/responses
- **Match and Replace**: Automatically modifies specific request content
### **Scanner**
- **Active Scanning**: Automated vulnerability detection
- **Passive Scanning**: Identifies vulnerabilities by monitoring traffic
- **Scan Configuration**: Custom scanning policies
### **Repeater**
- Manual request modification and resending
- Response comparison
- Essential for vulnerability verification
### **Intruder**
- Automated parameter brute-forcing
- Supports multiple attack types:
- Sniper
- Battering ram
- Pitchfork
- Cluster bomb
### **Other Key Modules**
- **Sequencer**: Analyzes session token randomness
- **Decoder**: Encoding/decoding tool
- **Comparer**: Response comparison
- **Extender**: Plugin management
## **4. Practical Application Cases**
### **Case 1: SQL Injection Testing**
1. Use Proxy to intercept login requests
2. Send to Repeater for parameter modification
3. Perform automated testing with Intruder
4. Analyze responses to identify injection points
### **Case 2: XSS Vulnerability Discovery**
1. Enable passive scanning
2. Manually test suspicious parameters
3. Use DOM Invader plugin to detect DOM XSS
## **5. Advanced Usage Techniques**
### **Plugin Extensions**
- **Logger++**: Enhanced logging
- **AuthMatrix**: Authorization testing
- **Turbo Intruder**: High-performance brute-forcing
- **Collaborator**: Out-of-band testing
### **Performance Optimization**
- Adjust memory settings (JVM parameters)
- Use filtering rules to reduce noise
- Configure appropriate scan speed
## **6. Defense Strategies**
### **Protection Against Burp**
- Implement WAF protection
- Detect abnormal request frequencies
- Use certificate pinning
- Monitor proxy traffic
