* | ClamAV (FreshClam): use a localized Database Mirror. | Guilhem Moulin | 2016-07-09 | 2 |
| | | | | | | 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 Moulin | 2016-06-05 | 1 |
| | | | | | 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 Moulin | 2016-05-24 | 3 |
| | | | | There is no need to bother with X.509 cruft here. | |||

| | ||||
* | Tunnel internal NTP traffic through IPSec. | Guilhem Moulin | 2016-05-22 | 2 |
| | | | | | | | 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 Moulin | 2016-05-22 | 13 |
| | | | | | | | | | | | | | | | 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 Moulin | 2016-05-18 | 2 |
| | | | | | | | | 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 Moulin | 2016-05-18 | 2 |
| | | | | | | | | | | 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 Moulin | 2016-05-18 | 1 |
| | | | | 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 Moulin | 2016-05-18 | 3 |

* | bacula: Set heartbeat options. | Guilhem Moulin | 2016-05-12 | 2 |
