How can I lock down ubuntu?

manpreet Best Answer 2 years ago

I am working on a small project. I have about 20 computers with Ubuntu 10.04 on them, which will be used in a computer lab for elementary, middle, high school and college kids. Some seniors and new computer-users will be using the computers.

I want to lock-down the computers for so children and people who want to play around with PC configuration can use them securely and without breaking them.

I therefore want to restrict user privileges, removing the ability to upgrade, add/install software or otherwise personalize the lab's computers.

The only uses for these computers should be:

1. access to school websites for access of e-text books (homework assignments)

2. access to learning-aid websites(such as www.math.com or webster.com)

3. access/restrictions to applications that are safe and appropriate for the elementary students.

4. For more senior users only, access to websites for completing applications for re-certifications of say food stamps, medicaid and so on.

Are there any software packages that will let me do this?
