IMPORTANT
---------

PHP5 only - at least 5.1.6 - 5.2.x recommended

DESCRIPTION
-----------

This module adds a security layer to Drupal based on PHPIDS (phpids.org).
With a defined set or rules, it tries to detect malicious input from the (anonymous)
user - it does not strip, filter or sanitize the input. It logs directly to watchdog 
or syslog (if enabled), so you have a clear view on who's trying to break your site. 
It can send out a mail after a certain level of impact has been reached or redirect the 
user to another page thus making his action completely worthless.

Although the functionality is there to redirect users after a certain impact, I 
advise you to only log the attacks for now as I have to think about how to implement
white lists and so on. Sending a mail is, at this moment, a better option.

INSTALLATION
------------

1) Download the latest PHPIDS package from http://www.phpids.org. 
2) Unpack the tar/zip and move the IDS directory in phpids-0.x/lib 
   to the module directory of phpids. 
3) make sure the IDS/tmp folder is writable (for caching the filters)
   On Unix do chown webuser:webuser IDS/tmp (or a chmod 666, but try to avoid that)
   
There is a Config.ini in the IDS/Config folder, do not worry, it's harmless, just keep
it like it is.

CONFIGURATION AND TESTING
-------------------------

After that, enable the module and surf to the settings page on
http://yourdrupal/?q=admin/logs/phpids/settings and change the default
settings to your needs.

Test if PHPIDS starts logging (not as user 1)

* normal log level
  http://yourdrupal/?q=admin/reports/watchdog&test=">XXX
* mail level - if you filled in an email
  http://yourdrupal/?q=admin/reports/watchdog&test=">XXX<"><script>
* warning level - redirects the (anonymous) user
  http://yourdrupal/?q=admin/reports/watchdog&test=<script>alert('hi')</script>&test2=<script>alert('hi2')</script>

You should see the attacks logged in your dblog or in your syslog file.
