gowafp

gowafp

A Go WAF (Web Application Firewall) that sits between your webserver (nginx) and your FastCGI application.

nginx <- (tcp) -> gowafp <- (FastCGI) -> PHP-FPM

The goal of this package is to prevent any attacks from reaching the FastCGI application. It should block all SQL injection attempts and filter XSS attempts. Maybe down the road it could also handle CSRF.

An Application and the Web Application Firewall should not be on different servers. While the services out there do a good job, they're expensive and slower. Of course, you could recompile your web server with some additional features, but that is harder to deploy while scaling.

usage

First, you need to have Go get the repo.

go get github.com/levidurfee/gowafp

Below is simple main.go example.

package main

import (
	"github.com/levidurfee/gowafp"
	"log"
	"net/http"
)

func main() {
	http.Handle("/", gowafp.AnalyzeRequest(gowafp.PhpHandler("/app/index.php", "tcp", "127.0.0.1:9000")))

	log.Fatal(http.ListenAndServe(":8080", nil))
}

Then build and run it.

go build main.go
./main
