KEEPING JOOMLLA SAFER

Over the last couple of weeks we've seen quite a few components abused to hack or deface sites. A lot of those exploits could have been avoided if these servers were running register_globals off. (Read carefully, i'm not talking about all hacks, but a lot of them)
A lot of information about what register globals actually is, can be found on the php.net site.

Now, to turn register globals off:
1) locate your php.ini configuration file
2) look for this line: register_globals = On
3) change it to: register_globals = Off
4) safe the file and restart apache

That is all to keep you a bit safer.
Now, if you don't have access to your php.ini file, you can try to use a .htaccess file to change this configuration value. Add the following code anywhere in your .htaccess file:

php_value register_globals off
Then save the file.
And last,

open globals.php
Change: define( 'RG_EMULATION', 1 );
To: define( 'RG_EMULATION', 0 );
And save the file.
