In a Workgroup Environment: To install Silversync, a local administrator account is needed.

File access methods

Silverback has two methods of access files for users. These are called Server Authenticates and User Authenticates. Depending on your decision the Silversync configuration will be split into different ways. So before you start to install Silversync, make the decision what you want to apply.

Server Authenticates

Server Authenticates is the functionality that the legacy Silversync system used. This means that the Silversync computer object needs permissions on all files users will synchronize. Access to the files is governed by assigned Tags.

Using this method, the server will access the content for the user. This requires that the Server has READ permissions to the file locations.

Server authenticates operates complete in Read Only mode. Administrators can provide content in folders and users are able to upload files via Personal File Management console. Consuming on end user devices will be in read only mode.

User Authenticates

User Based authentication means that the individual user’s file permissions are used. This means that a user must be granted minimum read permissions on files and folders before they will be able to sync it.

Administrators can assign content to users and users can upload files to accessible folders and shares. Any content where the user does not have proper NTFS permissions will not be listed or blocked from uploading

Files can be accessed with Read/Write permissions. Administrators can provide content in folders and users are able to upload files via Personal File Management console and M42Mobile application

Firewall Rules

Traffic source (from)	Destination (to)	Port Protocol
Devices (Internet)	Reverse Proxy	443/tcp
Reverse Proxy	Silversync Server	443/tcp
Admin Workstation	Silversync Server	3389/tcp
Silversync Server	Domain Controller	389,636/tcp
Silversync Server	Silverback Server	443/tcp
Devices (Wi-Fi)	Silversync Server	443/tcp

DNS

The Silversync server needs to be accessed from the Internet and the internal network; therefore, you need to create DNS entries in your respective DNS servers (where imagoverum.com is equal to the external company domain name).

The external DNS name for Silversync is silversync.imagoverum.com
The internal DNS name for Silversync is silversync.imagoverum.com

An authoritative DNS aliases needs to be created for silversync.imagoverum.com and it must resolve to IP the external interface of the Reverse Proxy or DMZ Proxy. An internal DNS aliases needs to be created for silversync.imagoverum.com and it must resolve to the Silversync server interface.

SSL

The Silversync solution allows users to securely synchronize content to their devices and requires an established trust relationship between the device and server. The Silversync web service requires one certificate signed by a Certificate Authority trusted by the devices. The certificate must also match the DNS Name outlined in previous section

A full list of iOS trusted Certificate Authorities is available at: http://support.apple.com/kb/HT5012.

The Silversync Website Certificate is a core requirement for Silversync to function, so please have the PFX/P12 Certificate Bundle available during installation.
