Problème d'ouvertue de port non désirée sur une configuration IPTABLES

Un problème de contournement des règles iptables fixées par utilisateur peut survenir avec l’utilisation de règles iptables RELATED,ESTABLISH trop générique et le chargement de helper de service non présent ou non utilisé sur la machine (exemple FTP actif, SIP, IRC …).

True fact: Mon server MariaDB s'est fait attaqué comme ça alors que le port dans l'iptable n'était pas ouvert.

NOTE: This is no longer an experiment! You can use the accessibility inspector in Chrome Devtools now, including a fantastic color contrast inspection tool. Read more: https://developers.google.com/web/updates/2018/01/devtools#a11y

Just like any good element inspector helps you debug styles, accessibility inspection in the browser can help you debug HTML and ARIA exposed for assistive technologies such as screen readers. There's a similar tool in Safari (and reportedly one in Edge) but I like the Chrome one best.

As an internal Chrome experiment, this tool differs from the Accessibility Developer Tools extension in that it has privileged Accessibility API access and reports more information as a result. You can still use the audit feature in the Chrome Accessibility Developer Tools, or you could use the aXe Chrome extension. :)

To enable the accessibility inspector in Chrome stable:
