## What is Naxsi?

NAXSI means [Nginx](http://nginx.org/) Anti [XSS](https://www.owasp.org/index.php/Cross-site_Scripting_%28XSS%29) & [SQL Injection](https://www.owasp.org/index.php/SQL_injection). 

Technically, it is a third party nginx module, available as a package for

many UNIX-like platforms. This module, by default, reads a small subset of

[simple (and readable) rules](https://github.com/nbs-system/naxsi/blob/master/naxsi_config/naxsi_core.rules)

containing 99% of known patterns involved in

website vulnerabilities. For example, `<`, `|` or `drop` are not supposed

to be part of a URI.

Being very simple, those patterns may match legitimate queries, it is

the Naxsi's administrator duty to add specific rules that will whitelist

legitimate behaviours. The administrator can either add whitelists manually

by analyzing nginx's error log, or (recommended) start the project with an

intensive auto-learning phase that will automatically generate whitelisting

rules regarding a website's behaviour.

In short, Naxsi behaves like a DROP-by-default firewall, the only task

is to add required ACCEPT rules for the target website to work properly.

## Why is it different?

Contrary to most Web Application Firewalls, Naxsi doesn't rely on a

signature base like an antivirus, and thus cannot be circumvented by an

"unknown" attack pattern.

Naxsi is [Free software](https://www.gnu.org/licenses/gpl.html) (as in freedom)

and free (as in free beer) to use.

## What does it run on?

Naxsi should be compatible with any nginx version.

It depends on `libpcre` for its regexp support, and is reported to work great on NetBSD, FreeBSD, OpenBSD, Debian, Ubuntu and CentOS.
