How to disable WebDav in AEM

Disable WebDAV
WebDAV should be disabled on both the author and publish environments. This can be done by stopping the appropriate OSGi bundles.

1. Connect to the Felix Management Console running on http://localhost:4502/system/console For example http://localhost:4503/system/console/bundles.
2. In the list of bundles, find the bundle named: Apache Sling Simple WebDAV Access to repositories (org.apache.sling.jcr.webdav)
3. Click the stop button (in the Actions column) to stop this bundle.
4. Again in the list of bundles, find the bundle named: Apache Sling DavEx Access to repositories (org.apache.sling.jcr.davex)
5. Click the stop button to stop this bundle.

Note:
A restart of AEM is not required.
