A network firewall can control which connections reach a server, but it cannot always determine whether an allowed HTTP request is malicious.
This is where a Web Application Firewall (WAF) becomes important.
A WAF examines HTTP and HTTPS requests before they reach the application. It can detect common attacks such as SQL injection, cross-site scripting, command injection, path traversal, and malicious file uploads.
For Linux and hosting servers, security is stronger when multiple layers work together:
- Network firewall controls ports and connections
- WAF inspects application requests
- DDoS protection detects abnormal request rates
- Intrusion prevention protects services such as SSH and FTP
- Monitoring provides visibility into security events
The important part is making these layers work together without unnecessarily blocking legitimate users.
BashEdge combines these protection layers into one server-security platform and supports environments including cPanel, Plesk, and Ubuntu Server.
