Now after a year and four months into it, Securich is still in Beta but MANY MANY more features were included, bugs fixed (others created) and it even made it through two sessions at the Oreilly MySQL Conference and Expo 2010 and two mysql university sessions.

The end points here are:
1. Share your knowledge and code with the community, we learn, you learn!
2. When you fall to the ground, climb back up and get on your feet again. Start running!
3. Securich is now at version 0.3.0 (10th official release), help yourself at google code your feedback is greatly appreciated!

Most of the new release is bug fixes but some of the features added in this version are:
1. Any user can now install securich not just mysql root
2. You can now grant privileges on the mysql db (by default still disabled as it runs in “strict” mode which needs to be changed to “lenient” manually)
3. The installation script now keeps the securich package intact for further many installations
4. Better error reporting (for debugging purposes)
5. Grants on tables using regexp are now case sensitive

The database design using workbench is also available in the db folder (for easier understanding of what lies beneath.

Cheers,
Darren

The tool is downloadable from there and anyone can use it for free in accordance to GPLv2.

I wanted to throw out tutorial about how to install it and use it (Note this tutorial is for version securich version 0.1.2):

Steps:
1. Download it,
2. Install it,
3. Create a role named 'role1' having privileges: select insert update
4. Check roles,
5. Check role privileges,
6. Create a first user john@machine.domain.com (granting privileges on a whole database employees apart from one table),
7. Create a second user paul@10.0.0.2 (granting privileges on all tables in world having word Country in them),
8. Create a third user peter@localhost (granting privileges on the database test),
9. Check user privileges for (paul),
10. Update role created above and see changes (add delete to role 1),
11. Update password (for paul) and see changes,
12. Clone user paul to judas,
13. Check user privileges
14. Check user,
15. Rename user judas to james,
16. Revoke privileges from third user disconnecting any existing connections from that user (useful if a security breach is suspected or if you are a security paranoid thus wanting to make sure the person you are blocking out won't have any more access as from that point onwards).

1. Go to www.securich.com downloads page and download the install script

I truly hope you enjoyed this run through. I excuse myself it's a tad too long, but I wished to illustrate some of the cool features of this package.

Cheers,
Darren

PS don't forget to check out Securich HERE

The name is SECURICH and downloads as well as documentation are available at http://www.securich.com/. The bug list is available at here. Privileges can be granted on a database or table level with a few combinations like:
1. database as one,
2. all tables in database (useful when you need to grant a bunch of privileges to all tables but a few thus revoking the few later),
3. single tables,
4. stored procedure or
5. tables through the use of regular expression.

The user has the facility to create a role and update it on the fly thus propagating the changes onto already existing users having the role in question. There are also loads of other functionalities available and I urge you to check the documentation on http://www.securich.com/.

A cool feature I like is password history which enables dbas to enforce changing of passwords after a certain period of time.

Features like block user and unblock user as well as many other functionalities are being developed and more features will be added as time goes by.

I would greatly appreciate your feedback about what you think of the package, features you might wish to include etc (feature requests should be done through http://www.securich.com/mantis/ as well.)
