*	Route SMTP traffic from the webmail through IPsec.	Guilhem Moulin	2016-07-10	1
\|
*	Use stunnel to secure the connection from the webmail to ldap.fripost.org.	Guilhem Moulin	2016-06-05	1
\| \| \| \| \|	We should use IPSec instead, but doing so would force us to weaken slapd.conf's ‘security’ setting.
*	Tunnel munin-update traffic through IPSec.	Guilhem Moulin	2016-05-22	1
\|
*	Set up IPSec tunnels between each pair of hosts.	Guilhem Moulin	2016-05-22	1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	We use a dedicated, non-routable, IPv4 subnet for IPSec. Furthermore the subnet is nullrouted in the absence of xfrm lookup (i.e., when there is no matching IPSec Security Association) to avoid data leaks. Each host is associated with an IP in that subnet (thus only reachble within that subnet, either by the host itself or by its IPSec peers). The peers authenticate each other using RSA public key authentication. Kernel traps are used to ensure that connections are only established when traffic is detected between the peers; after 30m of inactivity (this value needs to be less than the rekeying period) the connection is brought down and a kernel trap is installed.
*	Move /etc/ssl/private/dhparams.pem to /etc/ssl/dhparams.pem and make it public.	Guilhem Moulin	2016-05-18	1
\| \| \| \| \| \| \| \| \| \|	Ideally we we should also increase the Diffie-Hellman group size from 2048-bit to 3072-bit, as per ENISA 2014 report. https://www.enisa.europa.eu/publications/algorithms-key-size-and-parameters-report-2014 But we postpone that for now until we are reasonably certain that older client won't be left out.
*	Use systemd unit files for stunnel4.	Guilhem Moulin	2016-05-12	1
\|
*	Upgrade playbooks to Ansible 2.0.	Guilhem Moulin	2016-02-12	1
\|
*	Only install letsencrypt-tiny to the relevant hosts.	Guilhem Moulin	2015-12-28	1
\|
*	Use the Let's Encrypt CA for our public certs.	Guilhem Moulin	2015-12-20	1
\|
*	Change match to "^(Genuine)?Intel.*" for Intel processors.	Guilhem Moulin	2015-07-12	1
\|
*	Configure munin nodes & master.	Guilhem Moulin	2015-06-10	1
\| \| \| \| \|	Interhost communications are protected by stunnel4. The graphs are only visible on the master itself, and content is generated by Fast CGI.
*	Configure Bacula File Daemon / Storage Daemon / Director.	Guilhem Moulin	2015-06-07	1
\| \| \| \| \|	Using client-side data signing/encryption and wrapping inter-host communication into stunnel.
*	Install CAcert.org root certificates.	Guilhem Moulin	2015-06-07	1
\| \| \| \| \|	XXX: this is a workaround the CAcert root CAs not being present in Jessie. In stretch, we would merely install the 'ca-cacert' package.
*	logjam mitigation.	Guilhem Moulin	2015-06-07	1
\|
*	Don't instal smartd on KVM guests.	Guilhem Moulin	2015-06-07	1
\|
*	Upgrade the common package list.	Guilhem Moulin	2015-06-07	1
\|
*	Don't install intel-microcode on Xen guests.	Guilhem Moulin	2015-06-07	1
\| \| \| \|	It should be installed on the dom0 instead.
*	Don't install smartd on Xen guests.	Guilhem Moulin	2015-06-07	1
\| \| \| \|	S.M.A.R.T makes little sense for virtual HDDs.
*	Install auditd.	Guilhem Moulin	2015-06-07	1
\|
*	Don't install daemontools.	Guilhem Moulin	2015-06-07	1
\|
*	Replace IPSec tunnels by app-level ephemeral TLS sessions.	Guilhem Moulin	2015-06-07	1
\| \| \| \| \|	For some reason giraff doesn't like IPSec. App-level TLS sessions are less efficient, but thanks to ansible it still scales well.
*	Make genkeypair.sh able to display TXT record for DKIM signatures.	Guilhem Moulin	2015-06-07	1
\|
*	Don't require a PKI for IPSec.	Guilhem Moulin	2015-06-07	1
\| \| \| \| \| \| \| \| \| \| \|	Instead, generate a server certificate for each host (on the machine itself). Then fetch all these certs locally, and copy them over to each IPSec peer. That requires more certs to be stored on each machines (n vs 2), but it can be done automatically, and is easier to deploy. Note: When adding a new machine to the inventory, one needs to run the playbook on that machine (to generate the cert and fetch it locally) first, then on all other machines.
*	Install haveged.	Guilhem Moulin	2015-06-07	1
\| \| \| \| \| \|	To avoid low-entropy conditions, see http://www.issihosts.com/haveged/
*	Install ClamAV.	Guilhem Moulin	2015-06-07	1
\|
*	Install common packages.	Guilhem Moulin	2015-06-07	1
\|
*	Configure S.M.A.R.T.	Guilhem Moulin	2015-06-07	1
\|
*	Configure NTP.	Guilhem Moulin	2015-06-07	1
\| \| \| \| \| \|	We use a "master" NTP server, which synchronizes against stratum 1 servers (hence is a stratum 2 itself); all other clients synchronize to this master server through IPSec.
*	Reorganization.	Guilhem Moulin	2015-06-07	1
\|
*	Common LDAP (slapd) configuration.	Guilhem Moulin	2015-06-07	1
\|
*	Common MySQL configuration.	Guilhem Moulin	2015-06-07	1
\|
*	Postfix master (nullmailer) configuration	Guilhem Moulin	2015-06-07	1
\| \| \| \|	We use a dedicated instance for each role: MDA, MTA out, MX, etc.

\|
*	Configure IPSec.	Guilhem Moulin	2015-06-07	1
