The Hidden Tactics Cybercriminals Use in DDoS Attacks—and How You Can Outsmart Them Before It’s Too Late
4. Monitor network traffic and uptime
You can only identify a DDoS attack when you have the data to spot the signs of one.
An uptime monitoring service sends you alerts via email, SMS, or push notification when your site becomes unresponsive or goes offline. In addition, connecting your site to Google Analytics or a similar solution will help you understand traffic patterns and notice sudden spikes from single countries, IP ranges, or unknown referral sources.

If possible, you may also monitor server performance metrics like CPU load, memory usage, and bandwidth consumption for warning signs.
