Hi, do you know any tool and the process to follow for test the IPS I do know for example kalilinux, are there any attack to test the signatures of IPS
I guess the easy way is to setup VM on NB with Nexpose and via public connectiovity try to test your GW with IPS in front of.
Nexpose has easy web gui. You can use community version with some limitations. More info: https://www.rapid7.com/products/nexpose/compare-downloads.jsp
