I am fortunate this way; this is not my day job.  But I do not have an 
IT group to manage most of my systems I use to support my day job, so I 
am it.  Thus I lean on those of you that have this as a day job to 
figure out what I have not yet figured out.  I do try and help with what 
I know, but most of it is theory on things which are still a few years 
out.  What many of you are working with in security services, I was 
working on developing back when they were developed.  Like digital certs 
and PKI infrastructure as an example.  Today my efforts are in what is 
called 'the Internet Of Things' and 'Home Area Networks' and 'Medical 
Body Area Networks'. Mostly those little tiny things that most are not 
bothering to secure.

Thanks for all the help you people provide me.  Hopefully I will be 
helping to create technologies that will continue to provide you all 
with livelyhoods  :)

Oh, years ago I wrote about the importance of writing down important ids 
and passwords and putting them in a firebox with someone important 
knowing where it is.  There are lots of disaster stories out their, 
small and large, where the people that knew these were lost and data was 
or almost lost as well.  And I was talking to Tatu Ylonen, the creator 
of SSH (when he was a student in Helsinki), back in November on the 
disaster of SSH accounts at many large companies.  He has found banks 
with thousands of SSH accounts that no one knows whose they are or how 
to clean them up.  He is working on a set of tools to help out on this.
