Security
========
SSH host keys
-------------
+-----------+-----------------------------------------------------+
| Algorithm | Fingerprint |
+===========+=====================================================+
| RSA | ``82:91:22:22:10:75:ab:0e:55:05:9a:f9:98:cb:94:48`` |
+-----------+-----------------------------------------------------+
| DSA | ``6b:6e:59:37:41:83:a5:89:2a:18:04:23:51:53:5d:cd`` |

| ECDSA | \- |
+-----------+-----------------------------------------------------+
| ED25519 | \- |
+-----------+-----------------------------------------------------+
.. warning::
The system is too old to support ECDSA or ED25519 keys.
.. seealso::
See :doc:`../sshkeys`
Non-distribution packages and modifications
-------------------------------------------
:file:`/var/www/roundcubemail` contains a `Roundcube`_ 0.2.1 installation,
probably with patches.
.. todo::
Research wether Roundcube has been patched or not
:file:`/var/www/staff.php` is a custom built PHP script to show a list of
people with cacert.org email addresses.
:file:`/var/www/password.php` is a custom build PHP script to allow users to
reset their email password.
:file:`/var/www/board` contains the board voting system.
.. _Roundcube: https://roundcube.net/
Risk assessments on critical packages
-------------------------------------
The whole system is outdated, the PHP version is ancient, Roundcube is old.
Needs to be replaced as soon as possible.
Critical Configuration items
============================
Keys and X.509 certificates
---------------------------
* :file:`/etc/ssl/certs/ssl-cert-community-cacert.crt` server certificate
* :file:`/etc/ssl/private/ssl-cert-community-cacert.key` server key
* :file:`/usr/share/ca-certificates/cacert.org/` directory containing the
CAcert.org Class 1 and Class 3 CA certificates (allowed CA certificates for
client authentication and certificate chain for server certificate) with
symbolic links with the :command:`openssl` hashed certificate names
.. seealso::
* :doc:`../certlist`
* https://wiki.cacert.org/SystemAdministration/CertificateList
Apache configuration
--------------------
The Apache httpd configuration is stored in
:file:`/etc/apache2/sites-available/webmail`.
:file:`/etc/hosts`
------------------
Defines some aliases for :doc:`email` that are used by Roundcube, the password
reset script and the staff list script.
Roundcube configuration
-----------------------
The Roundcube configuration is stored in files in the
:file:`/var/www/roundcubemail/config/` directory.
