If your server has been hit by a DDoS attack, here are some steps you can take:
Restriction with firewalls and security groups: Limit traffic to your server to prevent further attacks.
Upgrade server resources: In order to cope with higher traffic, the server's memory, processor and other resources can be upgraded.
Install protection software: Install protection software, such as software that protects against DDoS attacks, to prevent future attacks.
Use a CDN service: Use a content delivery network (CDN) service to spread out traffic and reduce the impact of attacks on your server.
Report the attack to your ISP: If the attack persists, report the attack to your Internet Service Provider (ISP) for assistance.
Restrict source addresses: Reduce the impact of attacks by restricting specific source addresses and IP address ranges.
Router configuration: Modify the router configuration, such as enabling the DoS defense function, to prevent attacks.
Use elastic cloud services: Use elastic cloud services, such as Amazon Web Services (AWS), to reduce the impact of attacks on your servers.
Monitor the network: Monitor your network to understand attacks and determine the best solution. Use monitoring tools, such as network monitoring software and log analysis tools, to respond promptly when an attack occurs.
Seek help from a professional services company: If you are unable to handle a DDoS attack, seek help from a professional services company. These companies have specialized tools and technology to effectively protect against DDoS attacks.
NOTE: The most important thing is to keep your data and server secure. Therefore, make sure to take the best security measures when dealing with DDoS attacks.
