Depending on the security configuration of your Web server the recommended default permissions of 755 for directories and 644 for files should be reasonably secure.

755 only for writeable folders like components, modules, templates, caches and images.

except for that .. set to 664

The only file that needs to be writable is configuration.php. It should be set to 666.

You can find the list of folders by going to the Joomla admin area (the 'administrator' folder in your Joomla installation). Go to Help > System info in the menu then click Directory permissions. This page tells you whether they are writable or not. Folders should be set to 777.
