WAFW00F
WAFW00F allows one to identify and fingerprint Web App Firewall
The Web Application Firewall Fingerprinting Tool. Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions. If that is not successful, it sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is. If that is also not successful, it analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to our attacks. For further details,... -

UFW Docker
To fix the Docker and UFW security flaw without disabling iptables
UFW is a popular iptables front end on Ubuntu that makes it easy to manage firewall rules. But when Docker is installed, Docker bypasses the UFW rules and the published ports can be accessed from outside. Almost all of these solutions are similar. It requires disabling docker's iptables function first, but this also means that we give up docker's network management function. This causes containers will not be able to access the external network. It is also mentioned in some articles that you...
