Hello,

We are actually evaluating "Puppet Open Source Project" as the tool
for managing our hosting processes and we have a question about the
security in Puppet.

As far as we have read, there are only two places where the security
is taken into account:
- the connection between the server and the client (using
certificates)
http://projects.puppetlabs.com/projects/1/wiki/Certificates_And_Security
- the access to the Puppet Dashboard (using Http basic authentication
for exemple)
http://docs.puppetlabs.com/dashboard/manual/1.2/configuring.html

Could you tell us if there are other aspects of security in puppet
that we have not seen please ?

Our first need is to have security on the following main features:
- add / edit / delete Manifests on the Puppet Master
- add / edit / delete Nodes on the Puppet Master
- add / edit / delete bindings between Manifests and Nodes on the
Puppet Master

The only way we can think about for the moment in order to meet this
security needs is to:
1) Have all the configuration of the Puppet Master stored in
Subversion
2) Define a fine-grained security on the subversion
3) Prevents all access to the Puppet master by ssh in order to prevent
manual file changes on the Puppet Master
4) regularly update the configuration files of puppet from the
subversion

So the whole security would be implemented on subversion, for
exemple:
- a user who is not allowed to commit in the subversion, is not
allowed to change any configuration.
- a user can be allowed to change the manifests, but won't be allowed
to change the binding between manifests and nodes
- there will be a branch for each environment (dev, preprod, prod), so
only specific users will be allowed to change prod manifest, nodes and
bindings.
- etc.

Is it a good solution ?

Is there a better solution in order to restrict access as described
below please ?

Thanks in advance for your answers

Best regards,
Christophe
