Apps – Fabien Vincent

Après installation d’un serveur de mail pour remplacer Google Apps sur mon domaine perso, j’ai trouvé que Roundcube était le seul webmail qui me plaisait à peu près.

Quelques tips et tricks sur la sécurisation de Apache / PHP et Roundcube, pas sur les serveurs Postfix / Dovecot, qui je l’espère, viendront ici alimenter le blog avec du fail2ban …

Configuration du vHost et sécurisation dossiers “sensibles”

<VirtualHost *:443>
        ServerAdmin postmaster@beufa.net
        ServerName  x.beufa.net
        DocumentRoot /var/www/x
        SSLEngine on
        SSLCipherSuite ALL:!ADH:RC4+SHA:+HIGH:+MEDIUM:+LOW:+EXP:+eNULL
        SSLProtocol all -SSLv2
        SSLStrictSNIVHostCheck on
        SSLOptions StrictRequire
        SSLCertificateFile     cert.pem
        SSLCertificateKeyFile  cert.pem
        #GnuTLSEnable on 
        #GnuTLSPriorities SECURE:!ANON-DH:!MD5
        #GnuTLSCertificateFile cert.pem
        #GnuTLSKeyFile cert.pem
        #GnuTLSCertificateChainFile cert.pem
        #GnuTLSCACertificatePath /

        <Directory /var/www/roundcube>
                Options FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>

        <Directory /var/www/roundcube/config>
                Options -FollowSymLinks
                AllowOverride None
        </Directory>

        <Directory /var/www/roundcube/temp>
                Options -FollowSymLinks
                AllowOverride None
        </Directory>

        <Directory /var/www/roundcube/logs>
                Options -FollowSymLinks
                AllowOverride None
                Order allow,deny
                Deny from all
        </Directory>

        <Directory /var/www/roundcube/plugins/enigma/home>
                Options -FollowSymLinks
                AllowOverride None
                Order allow,deny
                Deny from all
        </Directory>

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        ErrorLog ${APACHE_LOG_DIR}/05.x.beufa.net_error.log
        CustomLog ${APACHE_LOG_DIR}/05.x.beufa.net_access.log combined

</VirtualHost>

Supprimer les headers de mail PHP verbeux dans /etc/php5/apache2/php.ini

; Decides whether PHP may expose the fact that it is installed on the server
; (e.g. by adding its signature to the Web server header).  It is no security
; threat in any way, but it makes it possible to determine whether you use PHP
; on your server or not.
; http://php.net/expose-php
expose_php = Off
; Add X-PHP-Originating-Script: that will include uid of the script followed by the filename
; Example for Roundcube : X-PHP-Originating-Script: 33:main.inc in each mail sent 
mail.add_x_header = Off

Avoir des logs Apache / PHP dans un fichier spécifique

; The path to a log file that will log all mail() calls. Log entries include
; the full path of the script, line number, To address and headers.
;mail.log = /var/log/mail.apache-php.log
