-Windows Defender AV uses both [cloud-delivered protection](utilize-microsoft-cloud-protection-windows-defender-antivirus.md) (also called the Microsoft Advanced Protection Service or MAPS) and periodically downloaded protection updates to provide protection. These protection updates are also known as "definitions" or "signature updates".
-
-The cloud-delivered protection is “always-on” and requires an active connection to the Internet to function, while the protection updates generally occur once a day (although this can be configured).

 There are two components to managing protection updates - where the updates are downloaded from, and when updates are downloaded and applied.

-## Manage the fallback order for downloading protection updates

 There are five locations where you can specify where an endpoint should obtain updates. Typically, you would configure each endpoint to individually download the updates from a primary source and specify fallback sources in case the primary source is unavailable.
