NAXSI means Nginx Anti XSS & 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
|
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.
