Technical evoluon from Cosy 131 to Cosy+
SSH-0301-01-EN
1. Introducon
Following the success of the Cosy 131, the Ewon® Cosy+ is the new generaon of Ewon industrial remote access
gateway, made even more secure and easy to use. With its embedded hardware security chip and updated
authencaon and encrypon protocols, the Ewon® Cosy+ provides state of the art end-to-end security for
remote access of automaon devices through the Talk2M cloud service. Meanwhile, its enhanced rmware
management opons and upgraded commissioning system make it even easier to deploy and maintain.
This document is designed to help customers to understand the implicaons of applying the new generaon
Ewon® Cosy+ products:
• The physical installaon of the Ewon® Cosy+ is the same as for the Cosy 131 product (same casing, same
mounng and same power supply & connectors)
• The soware conguraon of the Ewon® Cosy+ is very similar to the Cosy 131 product. It involves several
security enhancement and details are listed below

3. Security Enhancements
The Ewon® Cosy+ has been designed to have state of the art security capabilies. Most of these security
enhancements, such as a built-in secure element chip and new mechanisms to prevent cloning and
counterfeing, will be invisible to users. However, there are a few things that users may noce. These include:
•Mandatory Adm Password Change The password of a Ewon® Cosy+ must be changed and cannot be kept
as the default "adm". The password can be changed as part of the eCatcher Easy Setup Conguraon
Enhancements (page 5)eCatcher Easy Setup Conguraon Enhancements or during the rst access to the
Ewon® Cosy+ conguraon webpage.
The password of the Ewon® Cosy+ must be at least 12 characters long and respect 3 of the following
condions:
- include at least one lowercase character,
- include at least one uppercase character,
- include at least one digit,
- include at least one special character.
•Password retained aer Level 1 Reset
In the Cosy 131, the adm password is reset to its default seng as part of a level 1 reset. For the Ewon® Cosy+,
the password is not changed with a level 1 reset; it only is reset as part of a level 2 reset.
•Secure Boot Sequence
The Ewon® Cosy+ has a secure boot sequence to ensure that only code signed by Ewon is executed. This new
boot sequence is longer than the boot sequence of the Cosy 131 and during the majority of the sequence the
USR LED will be OFF.
•No VPN Keys in Backup
The VPN Keys are not included in a backup of a Ewon® Cosy+. If a user resets their Ewon® Cosy+ and then
restores a backup, the user will need to rerun the Talk2M wizard on the Ewon® Cosy+.

4. New Firmware Update Process
eBuddy is not used for rmware updates with the Ewon® Cosy+.
Instead, a new Firmware Update opon has been added to the Setup menu of the web interface of the Ewon®
Cosy+. From this opon, users can manually update the rmware of their Ewon® Cosy+ or congure it to
automacally retrieve and apply rmware updates.
The Ewon® Cosy+ can be congured to:
•Automacally apply only security patches
•Automacally apply the most recent ocial release
•Automacally apply the most recent release, including pre-release rmware.
NOTICE
Pre-release rmware should be applied to units only for tesng purposes unless told otherwise by a
support representave.

5. eCatcher Easy Setup Conguraon Enhancements
Users using the eCatcher Easy Setup to congure their Ewon® Cosy+ no longer need to run the System Wizard
in the web interface aer applying the conguraon les via SD card or USB ash drive. For a Ewon® Cosy+, the
System sengs such as the date and me sengs, language sengs, and adm password can be congured as
part of the eCatcher Easy Setup Wizard.
NOTICE
This requires eCatcher version 6.10.0 or later.

7. Ewon® Cosy+ Device Status Report
The Ewon® Cosy+ oers the ability to retrieve useful troubleshoong informaon without making a backup with
eBuddy or connecng to the device’s web interface.
If a USB drive or SD card with a text le named request_report.txt is inserted into a powered-on Ewon® Cosy+,
the le is replaced with a .tar device status report. This le contains key conguraon sengs and diagnosc
informaon for debugging support issues.
The le is ready and the USB drive/SD card can be removed when the USR LED becomes solid green.
CAUTION
The Ewon® Cosy+ Device Status Report is not a full backup.
It cannot be used to restore a reset device and does not include sensive informaon such as
passwords.
The Ewon® Cosy+ automacally generates the request_report.txt le during the inial inseron of the USB
drive/SD card as part of the Easy Setup process.
