ModSecurity is a powerful web application layer firewall for Apache web servers. It monitors the entire HTTP traffic to a website without affecting its operation and when it discovers an intrusion attempt, it prevents it. The firewall furthermore keeps a more thorough log for the traffic than any web server does, so you will be able to keep an eye on what is going on with your sites much better than if you rely simply on standard logs. ModSecurity works with security rules based on which it helps prevent attacks. For instance, it identifies whether anyone is trying to log in to the administration area of a particular script multiple times or if a request is sent to execute a file with a particular command. In such circumstances these attempts trigger the corresponding rules and the firewall software blocks the attempts instantly, after that records in-depth info about them within its logs. ModSecurity is one of the very best software firewalls available and it could easily protect your web apps against thousands of threats and vulnerabilities, particularly in case you don’t update them or their plugins frequently.
