[trustable-software] Security vs. Safety in Linux

[Ben Brewer]

Hi all,

In a discussion with Paul Sherwood, Will Barnard and a few others 
yesterday we were talking about the potential for using a security 
focused distribution as a basis for a safe distribution. We were 
specifically discussing the Purism project, but I think for the purposes 
of this discussion it could be any security focused distribution.

I made the point that I think in a lot of cases, prioritizing security 
sacrifices determinism, which would be a concern if used in a safety 
context.

The example I gave was Address Space Layout Randomization:
https://en.wikipedia.org/wiki/Address_space_layout_randomization

I think there are more examples, but I haven't looked deeply enough yet.

I don't think there's a single definite answer to any of this, but 
hopefully the discussion is worth having.

Regards,
Ben
