Dear David.
Why do you trust VPN more than the SSH?
I ask because I have just removed the "first VPN then SSH" solution
in favor for a SSH only solution using Gitosis just to get rid of the
VPN which I believe is less secure than SSH (well until I read you
comments below).
I thought I was doing something right for once but maybe I'm not?
Thanks and best regards

in part it's that a VPN is a single point of control for all remote
access.
If you use ssh you end up exposing all the individual machines
1. data leakage of just what machines exist to possibly hostile users.
2. the many machines are configured seperatly, frequently by different
people. this makes it far more likely that sometime some machine will
get misconfigured.
3. people who are focused on providing features have a strong
temptation to cut corners and just test that the feature works and not
test that everything that isn't supposed to work actually doesn't
work. as a result, in many companies there is a deliberate seperation
(and tension) between a group focused on controlling and auditing
access and one that is focused on creating fucntionality and features.
also from a polical/social point of view everyone recognises that if
you grant someone VPN access you are trusting them, but people don't
seem to think the same way with ssh.

I opened port 22 in the firewall to just those hosts that I need to
reach, which is one in this case...the rest of the machines I cannot reach.
I did a brief port scan and the thing is silent... so I don't think I
reveal any of the other hosts... but I should not say is it's secure
with your measures...
Your point two I don't understand... If you are in charge of the
firewall you also know what machines you let people reach. If these
machines are numerous then I think there is a management problem
somewhere else...
Point 3 is correct but I fail to see how this is less of a problem with
VPN than SSH.
Thanks and Best regards
