Load Guardian DDoS protection tool

A defensive load balancer in Go that includes DDoS protection features.

This load balancer implements several defensive features:

1. DDoS Protection:

   • Rate limiting per IP address
   • Burst protection
   • Automatic IP blocking for repeat offenders
   • Configurable thresholds and block durations

2. High Availability:

   • Health checking of backend servers
   • Automatic failover
   • Backend recovery detection

3. Load Distribution:

   • Round-robin load balancing
   • Dead backend detection
   • Dynamic backend pool management

To use this load balancer:

1. Create a config.json file:

{
    "backends": [
        "http://backend1:8081",
        "http://backend2:8082",
        "http://backend3:8083"
    ],
    "rate_limit": 60,
    "burst_limit": 10,
    "block_threshold": 3,
    "block_duration": 30
}

2. Run the load balancer:

go run loadbalancer.go

Remember to always combine this with other security measures like:

• Web Application Firewall (WAF)
• SSL/TLS encryption
• Regular security audits
• Network monitoring
