Security Guide for Connect for DocuSign Application i
Preface
Purpose
The purpose of the Security Guide is to disclose information for Xerox
®
apps with respect to device
security. Device security, in this context, is defined as how data is stored and transmitted, how the
product behaves in a networked environment, and how the product may be accessed, both locally
and remotely. This document describes design, functions, and features of the Xerox
®
apps relative
to Information Assurance (IA) and the protection of customer sensitive information. Please note
that the customer is responsible for the security of their network and the Xerox
®
apps do not
establish security for any network environment.
This document does not provide tutorial level information about security, connectivity or Xerox
®
app
features and functions. This information is readily available elsewhere. We assume that the reader
has a working knowledge of these types of topics.
Target Audience
The target audience for this document is Xerox field personnel and customers concerned with IT
security. It is assumed that the reader is familiar with the apps; as such, some user actions are not
described in detail.
Disclaimer
The content of this document is provided for information purposes only. Performance of the
products referenced herein is exclusively subject to the applicable Xerox
®
Corporation terms and
conditions of sale and/or lease. Nothing stated in this document constitutes the establishment of
any additional agreement or binding obligations between Xerox

1. General Security Protection
User Data Protection within the products
Document and File Security
File content is protected during transmission by standard secure network protocols at the channel
level. Since document source content may contain Personally Identifiable Information (PII) or other
sensitive content, it is the responsibility of the user to handle the digital information in accordance
with information protection best practices.
Hosting Microsoft Azure
The cloud services are hosted on the Microsoft Azure Network. The Microsoft Azure Cloud
Computing Platform operates in the Microsoft
®
Global Foundation Services (GFS) infrastructure,
portions of which are ISO27001-certified. Microsoft has also adopted the new international cloud
privacy standard, ISO 27018. Azure safeguards customer data in the cloud and provides support
for companies that are bound by extensive regulations regarding the use, transmission, and
storage of customer data.
The Apps hosted in the cloud are scalable so that multiple instances may be spun up/down as
needed to handle user demand. The service is hosted both in the US and Europe. Users will be
routed to the closest server geographically based on server load and network speed.
Cloud Storage – Microsoft Azure
All Azure Storage and Azure SQL data is secured when at rest using AES-256 encryption.

Xerox
®
Workplace Suite/Cloud and Single Sign-On Services
The Xerox
®
ConnectKey App Single Sign-On feature integrates with the Xerox
®
Workplace
Suite/Cloud authentication solution to store user access information for SSO-compatible Xerox
Gallery Apps. After the user enters their storage service credentials the first time, the XWS/C
solution acts a storage vault where the login information is securely stored.
All content to be stored in the vault is encrypted with AES 256 by the SSO Manager server before
being given to the SSO vault that resides on the XWS/C solution. This ensures that the SSO vault
can never view or use the contents being stored in the vault. Only the SSO Manager infrastructure
knows how to decrypt the content stored in the vault and only the App knows how to use it.
The SSO Manager service manages the encryption key exchange required for secure
communications and encrypts/decrypts the content saved in the vault.

User Data in transit
Secure Network Communications
The web pages and app services that constitute the Xerox
®
solution are deployed to Microsoft
Azure App Services. All web pages are accessed via HTTPS from a web browser. All
communications are over HTTPS. Data is transmitted securely and is protected by TLS security for
both upload and download. The default TLS version used is 1.2.
The Xerox
®
app requires the user to provide proper/valid credentials in order to gain access to the
application’s features. Authenticated users are allowed to access the features and data using
HTTPS.
At launch, the apps must get an authentication/session token through the solution’s authentication
process. The access token acquired is used for that session of the app.
When using the ConnectKey App installed on a Xerox device, if the customer environment includes
an Authentication solution (e.g., Xerox
®
Workplace Suite/Cloud) with Single Sign-On functionality
enabled, the user can agree to have their user credentials securely stored and automatically
applied during subsequent app launches.
All communication is done via HTTPS and the data is transmitted securely and is protected by TLS
security. The default TLS version used is 1.2. Xerox App Gallery supplies a link to a Certificate
Authority root certificate for validation with the cloud web service. It is the responsibility of the
customer to install the certificate on their devices and to enable server certificate validation on
the devices.
For more information related to Azure network security, please follow the link:
https://docs.microsoft.com/en-us/azure/security/azure-network-security
Xerox
®
Workplace Suite/Cloud and Single Sign-On Services
The Xerox
®
Workplace Suite/Cloud server accepts credential storage requests from the App via the
SSO Manager service (the ConnectKey App retrieves a vault key from the SSO Manager and uses
it to retrieve login credentials from the XWS/C service). All communication is via HTTPS and the
data is transmitted securely and is protected by TLS security. The default TLS version used is 1.2.

®
Connect for DocuSign App –
Xerox
®
ConnectKey App
Description
Overview
ConnectKey App
The ConnectKey App is a simple document signing solution for your Xerox
®
device that integrates
with DocuSign eSignature workflows. The app assists the user with:
1. Browsing DocuSign envelopes and printing documents.
2. Scanning a hard copy document into their DocuSign account.
3. Selecting recipients and signature placement locations for scanned documents.
Table 1. ConnectKey App user benefits
Application
What can I do?
ConnectKey App
App Hosting
The ConnectKey App depends heavily on cloud hosted components. A brief description of each
can be found below.
ConnectKey App
The ConnectKey App consists of two key components, the device weblet and the cloud-hosted web
service. The device weblet is a ConnectKey/EIP web app that enables the following behavior on a
Xerox device:
1. Presents the user with an application UI that executes functionality in the cloud.
2. Interfaces with the EIP API, which delegates work, such as document scanning and printing.
The weblet communicates with the cloud-hosted web service, which executes the business logic of
the app.
DocuSign eSignature Web Service
The solution depends on the DocuSign eSignature REST API to retrieve the user’s folders,
templates, and documents and to download and/or upload digital documents. All requests are
made over HTTPS.
Xerox

Security Guide for Connect for DocuSign Application 4
Single Sign-On via Xerox
®
Workplace Suite/Cloud and SSO Manager
In order to improve user experience, by removing the need to log in to the ConnectKey App each
time Xerox offers an optional Single Sign-On (SSO) capability. Users can log into the printer and
are then able to launch the app without the need to provide additional credentials.
Xerox Extensible Interface Platform
®
Web Services
During standard usage of the ConnectKey App, calls to the device web services are used to initiate
and monitor scan functions and to pull relevant details related to device properties and capabilities.
Components
MFD with Xerox
®
Audio Documents App – ConnectKey App
This is an EIP capable device that can scan and execute ConnectKey Apps installed from the
Xerox
®
App Gallery. In this case, the device has the Xerox
®
Connect for DocuSign App installed.
Xerox
®
Connect for DocuSign App – Web Services
The Web Service is a service hosted on the Microsoft Azure Cloud System. The service is
responsible for hosting the web pages which are displayed on the UI of the printer and provide the
services support for the Xerox
®
apps. The web service interacts with the DocuSign services using
the DocuSign eSignature APIs and Microsoft services using the Azure APIs.
DocuSign eSignature Web Service
The DocuSign cloud hosted service provides a web API that is used for the eSignature workflow
processes, which support the creation and downloading of digital documents for electronic signing.
