Is the idea of a single one-size-fits-all security policy reasonable?  I 
think Fedora has a broad range of users.

Security is a tradeoff.  If you make it impossible for the bad guys to get 
in, the good guys probably can't get any work done.  How secure do you need 
to be?  How much are you willing to pay for it?

I'd much rather have an overview document that explains the likely attacks 
and potential solutions, and their costs and benefits.  Additionally, I think 
it's much easier to follow a policy if I understand the reasonaing behind it.

I think sample policy documents with descriptions of their target audience 
and checklists for how to implement them would be helpful.

No.  Initially, I recommend one security policy and one reference 
implementation to test against.  Each variation needs its own security policy 
and reference implementation definition.  Later ones are easier to create 
because they can use the early ones as "guidance".

So, why go through all of this paperwork and bureaucratic bullshit?  Well, 
those of us who have done this before believe that it is necessary.  I do not 
like the bureaucratic BS any more than anyone else but, if you do not do it, 
then you are not quite sure what you have when you say that something meets 
security requirements.

Probably not but there are some basics that should be implemented for
everyone.

How much are you willing to pay to clean up the aftermath?

The Fedora Security Guide (found at docs.fedoraproject.org and in a friendly
repo near you) started out that way and has blossomed into that and a whole
lot more.  As always suggestions and patches are welcome.
