    UFW Docker

    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...

    The browser exploitation framework project

    ...It is a penetration testing tool that focuses on the web browser. Amid growing concerns about web-borne attacks against clients, including mobile clients, BeEF allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, BeEF looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser. BeEF will hook one or more web browsers and use them as beachheads for launching directed command modules and further attacks against the system from within the browser context.
