|From the SE Linux site:
“This work is not intended as a complete security solution for Linux. Security-enhanced Linux is not an attempt to correct any flaws that may currently exist in Linux. Instead, it is simply an example of how mandatory access controls that can confine the actions of any process, including a superuser process, can be added into Linux. The focus of this work has not been on system assurance or other security features such as security auditing, although these elements are also important for a secure system.”
Assuming that you are only considering security from a systems/OS perspective, I’d:
1. identify what am I trying to protect
2. identify what threats exist to whatever your trying to protect
3. you are backing up, right?
4. identify what tools are available to protect you
5. evaluate them in detail before coming to the conclusion that nothing else will provide you the level of comfort that you desire, or havea very specific understanding about how integrating SE Linux will enhance your current security protocol.
Personally, I have implemented Linux-based security soulutions in the financial industry, without SE Linux.
That said, SE Linux is a very interesting project. I’m excited to see how it develops.
