Software Update Services (SUS)

SUS Feature Brief Description
Built-in security The administrative pages of SUS are Web based through IIS and restricted to local administrators on the computer that hosts the updates. The synchronisation always validates the digital certificates on any downloads to the update server. Any files that are not from Microsoft are automatically deleted.
Selective content approval Administrators can choose which updates they want to be available to clients. This allows you to test the packages before deploying them.
Content synchronisation You receive the latest critical updates and service packs from Microsoft through the process of synchronisation. You can set a schedule for automatic synchronisation at preset times. Alternatively, you can use the Synchronize Now button to manually synchronise the server.
Server-to-server synchronisation You can point your server to another server running Microsoft SUS instead of to the Windows update server. This creates a single point of entry for updates into the network, without requiring that each SUS server download updates from the external Microsoft source.
Multi-language support SUS supports the publishing of updates to multiple operating-system language versions.
Remote administration via HTTP or HTTPS The SUS administrative interface is Web based. This allows you to manage it remotely as if you were sitting in front of the server itself. Remote administration requires Internet Explorer 5.5 or later.
Update status logging You can specify the address of a Web server where the Automatic Updates client should send statistics about updates that have been downloaded and installed.

Your logbook for this section should provide documentary evidence that you can specify the required ports and protocols for services and configure protocol security by using IPSec policies and that you can produce a security plan, taking account of security monitoring, change and configuration management and security update infrastructure.
