Module Link: http://drupal.org/project/content_access

The Content Access module allows you to specify view/edit/delete permissions on a node by node bais for roles while hooking into rules.

• Who: Technical users (Non-technical users can use it but why do non-technical users need to mess with permissions on a per-node basis)
• When: Use this module when you want to allow users to change if individual nodes can be viewed, edited or deleted by specific groups and/or you need to hook into rules. It also controls who can view nodes which the default Drupal permissions do not allow for.
• Where: Modify your Content Type to allow users to defined permissions on a node by node basis. In the individual nodes set the permissions.
• Why: Quite a few ACL type modules paint with a very broad stroke but this module lets you control it on a node by node basis giving you the highest possible resolution for your permissions. Note: If you use this module and don't use it for the node by node permissions then the only true benefit I can see is to controlling users viewing that node.
