If someone obtained a copy of the keytab from a -backup, that person could make any host masquerade as the host whose -keytab was compromised. In many configurations, knowledge of the -host’s keytab also allows root access to the host. This could be -particularly dangerous if the compromised keytab was from one of your -KDCs. If the machine has a disk crash and the keytab file is lost, it -is easy to generate another keytab file. (See <a class="reference internal" href="appl_servers.html#add-princ-kt"><span class="std std-ref">Adding principals to keytabs</span></a>.) -If you are unable to exclude particular files from backups, you should -ensure that the backups are kept as secure as the host’s root -password.</p> -<section id="backing-up-the-kerberos-database"> -<h2>Backing up the Kerberos database<a class="headerlink" href="#backing-up-the-kerberos-database" title="Link to this heading">¶</a></h2> -<p>As with any file, it is possible that your Kerberos database could -become corrupted. If this happens on one of the replica KDCs, you -might never notice, since the next automatic propagation of the -database would install a fresh copy. However, if it happens to the -primary KDC, the corrupted database would be propagated to all of the -replicas during the next propagation. For this reason, MIT recommends -that you back up your Kerberos database regularly. Because the primary -KDC is continuously dumping the database to a file in order to -propagate it to the replica KDCs, it is a simple matter to have a cron -job periodically copy the dump file to a secure machine elsewhere on -your network. (Of course, it is important to make the host where -these backups are stored as secure as your KDCs, and to encrypt its -transmission across your network.) Then if your database becomes -corrupted, you can load the most recent dump onto the primary KDC. -(See <a class="reference internal" href="database.html#restore-from-dump"><span class="std std-ref">Dumping and loading a Kerberos database</span></a>.)</p> -</section> -</section> -
