If you have the core Update Manager module installed, in the <em>Manage</em> administrative menu, navigate to <em>Reports</em> &gt; <em>Available updates</em> to see a report of the updates that are available for your site software. If <em>Last checked</em> is far in the past, click <em>Check manually</em> to update the report. Scan the report; if the core software or any modules or themes have security updates available, you should update them as soon as possible.
