By combining several strategies, you can significantly reduce the risks of a DDoS attack in the area of NTP time servers.

What strategies do we recommend for DDoS protection?

  • Software updates: Always keep the NTP server software up to date to close known security gaps.
  • Rate limiting: Limit the number of requests from a single IP address to minimize misuse.
  • Whitelisting: Allow only trusted IP addresses to access the NTP server.
  • Monitoring and alerting: Monitor traffic for unusual patterns or spikes that could indicate a DDoS attack and set alerts for such events.
  • Firewalls and IDS: Use firewalls and intrusion detection systems (IDS) to filter and monitor incoming traffic.
  • Geographic filtering: Block traffic from regions that are not relevant to your network.
