Nachdem Sie Mahara installiert haben, sehen Sie als Site-Administrator einige Hinweise. Beachten Sie alle Hinweise und nehmen Sie erforderlichen Einstellungen vor, um sicherzustellen, dass Ihre Seite so sicher wie möglich ist.

Example of a warning on the "Admin home" page

Example of a warning on the Admin home page

  1. Session entropy Länge: Ihre PHP session.entropy_Einstellung ist zu kurz. Setzen Sie sie in der php.ini mindestens auf 16, um sicher zu stellen, dass sichere Session IDs zufällig erzeugt werden nicht erratbar sind. Weitere Hinweise hierzu finden Sie im OWASP session management cheatsheet.

  2. Noreply E-Mailadresse: Wenn die System-E-Mailadresse fehlt oder fehlerhaft eingegeben wurde, werden Sie aufgefordert die Werte zu prüfen und zu korrigieren. Sehen Sie nach unter System E-Mailadresseinstellungen.

  3. Site-wide password salt: If you do not have one set, please edit your config.php file and set it to a reasonable length.

  4. SAML setup: If you do not have SAML authentication set up properly and do not have SAML activated, you do not see any warning messages as they would only go away if you activate the plugin and install all the required dependencies.

11.2.3. Registration

Administration menu → Admin home → Register

As site administrator you can choose to register your Mahara site with mahara.org and help us compile a list of Mahara installations around the world to get a picture by how many people Mahara is used. Currently, this list is not published online. When you are on the administration overview page, you will see a link directly to the registration page.

Site-Informationen

If you have problems with your Mahara instance and you request information from the community in the forums, this information, esp. about your version and the cron, are useful to have. Furthermore, the version number allows you to check that you have the latest security release of your Mahara version installed.

The cron job is very important in Mahara as a number of vital tasks are only performed when it is running. You can find more information of how to set it up on the wiki. If the cron is not running or only partially running, that information is displayed in red.

11.2.5. Clear caches

Administration menu → Admin home → Overview

A number of elements are cached in Mahara on the system level to speed up the site. In some cases, you may wish to force a new version though if the browser doesn’t recognize it on its own.

11.2.6. Plattform sperren

Since the site is not accessible to anyone unless they are logged into the site as site administrator, certain processes would also fail, e.g. accessing the SAML metadata that is monitored by IdPs. It is possible to add a flag to a php file to ignore maintenance mode.
