| * | Webmail: don't allow outgoing TCP/993 connections. | Guilhem Moulin | 2017-06-15 | 1 |
| | | | | | We're going through IPsec to communicate with the IMAP server. | |||
| * | postfix: enable XFORWARD command from our internal relays. | Guilhem Moulin | 2017-06-02 | 1 |
| | | ||||
| * | postfix: don't rate-limit our IPsec subnet. | Guilhem Moulin | 2017-06-02 | 1 |
| | | ||||
| * | Don't let authenticated client use arbitrary sender addresses. | Guilhem Moulin | 2017-06-01 | 1 |
| | | | | | | | | | | | | | | | 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. | |||
| * | Also install non-free firmwares on civett. | Guilhem Moulin | 2017-05-30 | 2 |
| | | ||||

| | | ||||
| * | postfix: Remove obsolete templates tls_policy/relay_clientcerts. | Guilhem Moulin | 2016-07-12 | 1 |
| | | ||||
| * | Route all internal SMTP traffic through IPsec. | Guilhem Moulin | 2016-07-10 | 3 |
| | | ||||
| * | Postfix: avoid hardcoding the instance names. | Guilhem Moulin | 2016-07-10 | 1 |
| | | ||||
| * | Postfix: don't share the master.cf between the instances. | Guilhem Moulin | 2016-07-10 | 1 |
| | | ||||
| * | Localize the NTP pool hostnames. | Guilhem Moulin | 2016-07-09 | 1 |
| | | ||||
| * | Localize the debian archive hostnames. | Guilhem Moulin | 2016-07-09 | 1 |
| | | ||||
| * | ClamAV (FreshClam): use a localized Database Mirror. | Guilhem Moulin | 2016-07-09 | 1 |
| | | | | | | | As db.local.clamav.net is not always properly localized. Furthermore, our previous Ansiblee script did not ensure ordering of the DatabaseMirror lines. | |||
| * | IPSec → IPsec | Guilhem Moulin | 2016-06-29 | 2 |
| | | ||||
| * | IPSec: replace (self-signed) X.509 certs by their raw pubkey for authentication. | Guilhem Moulin | 2016-05-24 | 1 |
| | | | | | There is no need to bother with X.509 cruft here. | |||
| * | Tunnel bacula (dir → {fd,sd} and fd → sd) traffic through IPSec. | Guilhem Moulin | 2016-05-22 | 3 |
| | | ||||
| * | Tunnel munin-update traffic through IPSec. | Guilhem Moulin | 2016-05-22 | 3 |
| | | ||||
| * | 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 | 5 |
| | | | | | | | | | | | | | | | | 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 | 1 |
| | | | | | | | | | 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.) | |||
| * | 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. | |||
| * | bacula: Set heartbeat options. | Guilhem Moulin | 2016-05-12 | 2 |
| | | | | | and also TCP keepalive options in the stunnel config. | |||
| * | Use systemd unit files for stunnel4. | Guilhem Moulin | 2016-05-12 | 2 |

| * | s/ansible_ssh_/ansible_/ | Guilhem Moulin | 2016-02-12 | 2 |
| | | ||||
| * | Postfix TLS policy: Store the fingerprint of the cert's pubkey, not of the ↵ | Guilhem Moulin | 2015-12-03 | 1 |
| | | | | | cert itself. | |||
| * | Internal Postfix config: Disable TLS protocols <1.2 rather than enable 1.2 only. | Guilhem Moulin | 2015-10-27 | 1 |
| | | ||||
| * | stunnel: disable compression. | Guilhem Moulin | 2015-10-27 | 2 |
| | | ||||
| * | stunnel: use GCM ciphers only; use SSL options rather than ciphers to ↵ | Guilhem Moulin | 2015-10-27 | 2 |
| | | | | | disable protocols. | |||
| * | Change match to "^(Genuine)?Intel.*" for Intel processors. | Guilhem Moulin | 2015-07-12 | 2 |
| | | ||||
| * | Use a single LDAP connection per Munin round to collect slapd statistics. | Guilhem Moulin | 2015-06-11 | 1 |
| | | | | | Using multigraphs instead. | |||
| * | slapd monitoring. | Guilhem Moulin | 2015-06-10 | 1 |
| | | | | | | We don't use the provided 'slapd_' Munin plugin because it doesn't support SASL binds. | |||
| * | Configure munin nodes & master. | Guilhem Moulin | 2015-06-10 | 4 |
| | | | | | | 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 | 3 |
| | | | | | | Using client-side data signing/encryption and wrapping inter-host communication into stunnel. | |||
