OctopusWAF is a open source Web application firewall, is made in C language uses libevent to make multiple connections.
Instal lib-pcre, if you use RPM based distros search pcre-devel package, in BSD based search in ports or brew... Need libevent-dev, on RPM distros libevent-devel, Openssl-dev and openssl-devel.
To compile and run OctopusWAF follow this commands:
$ git clone https://github.com/CoolerVoid/OctopusWAF
$ cd OctopusWAF; make
$ bin/OctopusWAF
Example tested on DVWA on simple HTTP channel
$ bin/OctopusWAF -h 127.0.0.1:2006 -r 127.0.0.1:80 -m horspool --debug
Open your browser in http://127.0.0.1:2006
- Notes: Don't execute with "cd bin; ./OctopusWAF" use full path "bin/OctopusWAF", because binary need load content in config directory. Use HTTP only for WAF usage, this version 0.1 run TLS but don't have resource to load cert and read TLS requests/responses, if you use TLS the service can lost WAF function and work like reverse proxy.
Tested on Linux but can run in FreeBSD.
