* Webmail: don't allow outgoing TCP/993 connections.Guilhem Moulin2017-06-151
| | | | We're going through IPsec to communicate with the IMAP server.

* Don't let authenticated client use arbitrary sender addresses.Guilhem Moulin2017-06-011
| | | | | | | | | | | | | | The following policy is now implemented: * users can use their SASL login name as sender address; * alias and/or list owners can use the address as envelope sender; * domain postmasters can use arbitrary sender addresses under their domains; * domain owners can use arbitrary sender addresses under their domains, unless it is also an existing account name; * for known domains without owner or postmasters, other sender addresses are not allowed; and * arbitrary sender addresses under unknown domains are allowed.

* FreshClam: change ownership of /etc/clamav/freshclam.conf.Guilhem Moulin2016-09-181
| | | | | | | | To match the stock version shipped by clamav-freshclam 0.99.2+dfsg-0+deb8u2 ~$ stat -c '%U:%G %a' /etc/clamav/freshclam.conf clamav:adm 444

* ClamAV (FreshClam): use a localized Database Mirror.Guilhem Moulin2016-07-092
| | | | | | As db.local.clamav.net is not always properly localized. Furthermore, our previous Ansiblee script did not ensure ordering of the DatabaseMirror lines.

|
* Use stunnel to secure the connection from the webmail to ldap.fripost.org.Guilhem Moulin2016-06-051
| | | | | We should use IPSec instead, but doing so would force us to weaken slapd.conf's ‘security’ setting.

* IPSec: replace (self-signed) X.509 certs by their raw pubkey for authentication.Guilhem Moulin2016-05-243
| | | | There is no need to bother with X.509 cruft here.
* genkeypair, gendhparam: use -rand /dev/urandom when generating keys or DH ↵Guilhem Moulin2016-05-222
| | | | parameters.
* Tunnel bacula (dir → {fd,sd} and fd → sd) traffic through IPSec.Guilhem Moulin2016-05-226
|
* Tunnel munin-update traffic through IPSec.Guilhem Moulin2016-05-227
|
* Tunnel internal NTP traffic through IPSec.Guilhem Moulin2016-05-222
| | | | | | | More precisely, between our NTP-master (stratum 1) host and the other machines (all stratum 2). Providing authentification and integrity for internal NTP traffic ensures a consistent time within our internal infrastructure.
* Set up IPSec tunnels between each pair of hosts.Guilhem Moulin2016-05-2213
| | | | | | | | | | | | | | | 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.

* postfix: Update to recommended TLS settings.Guilhem Moulin2016-05-182
| | | | | | | | Following Viktor Dukhovni's 2015-08-06 recommendation http://article.gmane.org/gmane.mail.postfix.user/251935 (We're using stronger ciphers and protocols in our own infrastructure.)
* Move /etc/ssl/private/dhparams.pem to /etc/ssl/dhparams.pem and make it public.Guilhem Moulin2016-05-182
| | | | | | | | | | 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.
* postfix: disable weak ciphers for the 'encrypt' TLS security level.Guilhem Moulin2016-05-181
| | | | That is, on the MSA and in our local infrastructure.
* Add an ansible module 'fetch_cmd' to fetch the output of a remote command ↵Guilhem Moulin2016-05-183
| | | | | | locally. And use this to fetch all X.509 leaf certificates.
* bacula: Set heartbeat options.Guilhem Moulin2016-05-122
| | | | and also TCP keepalive options in the stunnel config.
* Add hardening options to our systemd unit files.Guilhem Moulin2016-05-121

* Use systemd unit files for stunnel4.Guilhem Moulin2016-05-1211

* sysctl: don't set IPv6 privacy extensions globaly.Guilhem Moulin2016-04-011
