Prevent DDOS is always challenging. On a shared hosting environment it's always challenging to prevent DDOS and keep your server online. Here is some method which can prevent Layer 7 DDOS attack.

  1. 1. ModSecurity with OWASP Rulesets:

    • ModSecurity is an open-source web application firewall (WAF) module that can be integrated with cPanel to protect against various types of attacks, including Layer 7 DDoS attacks. By enabling ModSecurity and configuring it with OWASP Core Rule Set (CRS) or other rulesets, you can help mitigate the risk of common web application vulnerabilities and Layer 7 attacks.
  2. 2. LiteSpeed Web Server:

    • LiteSpeed Web Server is a high-performance web server that includes built-in features for DDoS mitigation, including rate limiting, IP blocking, and request throttling. By using LiteSpeed Web Server as an alternative to Apache, you can benefit from its advanced DDoS protection capabilities.
  3. 3. Cloudflare or Sucuri:

    • Cloudflare and Sucuri are popular cloud-based DDoS protection and website security platforms that offer Layer 7 DDoS mitigation services. By integrating your cPanel server with Cloudflare or Sucuri, you can offload DDoS traffic to their global network and benefit from their advanced filtering and caching capabilities.
  4. 4. CSF (ConfigServer Security & Firewall) with DDoS Configuration:

    • CSF is a firewall configuration tool for cPanel servers that can be customized to enhance DDoS protection. By configuring CSF to implement rate limiting, connection tracking, and other DDoS mitigation techniques, you can help prevent Layer 7 attacks and protect your server from excessive traffic.
  5. 5. Apache Mod_evasive:

    • Apache Mod_evasive is an Apache module that can help mitigate the impact of DDoS attacks by detecting and blocking suspicious requests from individual IP addresses. By enabling Mod_evasive on your cPanel server, you can add an additional layer of protection against Layer 7 DDoS attacks targeting Apache-based web applications.
  6. 6. Custom Scripting and Automation:

    • You can develop custom scripts or leverage existing tools to monitor server logs for signs of Layer 7 DDoS attacks and automatically block malicious traffic sources. By implementing proactive monitoring and mitigation strategies, you can help minimize the impact of DDoS attacks on your cPanel server.

It's important to note that no single solution can provide complete protection against all types of DDoS attacks, including Layer 7 attacks. Consider implementing a combination of these tools and techniques to create a comprehensive DDoS protection strategy for your cPanel server. Additionally, regularly monitor server performance and traffic patterns to detect and respond to DDoS attacks in real-time.
