Here are some strategies you can use to protect your network against DDoS attacks:

1. Add Rate Limiting: Rate limiting is when you set a specific limit of incoming requests your network can receive in a specified period of time. If the threshold is exceeded, the requests will be denied.
2. Employ Traffic Scanning: Using traffic scanning and related tools can help you narrow in on targets and detect malicious activity in your network.
3. Monitor Network Traffic: Regularly monitoring your network traffic and using measures like firewalls can help detect traffic anomolies. Firewalls allow you to control access to your network, and block suspicious connections.
4. Keep Server Network Traffic Seperate: Seperating your server network traffic from public traffic on shared connections helps prevent DDoS attackers from overwhelming your servers.
