Bring Your Own Device (BYOD) Keys to success:

' Economic advantages (reduced TCO)
' Easy maintenance and lifecycle management
' Increase of productivity
' Commercial off-the-shelf (COTS) hardware Source: Forrester Research, Inc. - 2013 Thin clients with
integrated RDP
SCADA Utilization of ''Thin Clients' connected via remote desktop to an
existing SCADA system
Main features:

' Endurance to harsh environment (dust,
vibrations, heat, water)
' Reduced Total cost of Ownership
' Increase of productivity (fast replacement)
' COTS hardware (commercial off-the-shelf) with
integrated RDP client or RDP/VNC apps Main issues:

' Limited number of remote desktop sessions (~25)
running on the server
' Performances depending on the RDP/VNC
connections and the number of clients
' Extra costs in the initial investment due to RDP CAL licenses on the terminal server RDP/VNC apps Pure Web Clients connected to an existing SCADA system configured
as Web Server
Main features: ' Access via IP address from any browser based on
HTML5 & SVG
' Independent from Web browser version (Zero Client
side installation and no upgrades needed on device)
' Hardware platform independent (Windows, Android,
Apple,..)
' SCADA information on WWW, LAN, WLAN
' No maintenance on the client device
' Monitoring and operation possible
' BYOD (bring your own device) Main issues:

' Security
' Audit trail
' Migration and scalability of existing project Security issues of plant remote control via Pure Web Clients In order to avoid as much as possible unauthorized access
to the SCADA server the following measures should be
taken:

- Adopt a plant security policy
- Protect the WIFI connection with WPA2 secure password
- MAC address filtering
- Disable, if possible, USB and SD card interfaces
- Access via HyperText Transfer Protocol Secure (HTTPS)
and SSL certificates
- Password rotation
- Training for operators to prevent social engineering
attacks (good security habits, information security
awareness')
In some cases it makes sense to limit the use of
handhelds to monitor only or adopt VPN as a single point
of entry for a secure http traffic. Extending SCADA features to mobile devices as an added value The utilization of remote monitoring and control through mobile devices should coexist with the
existing installations as an extra feature, guaranteeing continuity with the consolidated
technology. This means: The major players in the world of industry automation have
already enriched their SCADA portfolio
with new web options or apps for the
main mobile app markets. 'Migration from older versions of the SCADA
system to the new web technologies possible,
(saving the investment)
'Web publishing of the SCADA project with
integrated tools
'No extra engineering or web technology
required Some of them also offer dedicated industrial devices as
Thin-Clients and industrial Tablet-PCs. ''Use cases' '' focus on mobile devices as pure web clients Management
'Monitoring production equipment from everywhere
'Better support for real-time decision
'Best informed anytime everywhere

Maintenance
'Mobile access to each equipment
'Simplified access even on wide distributed plants
'Faster reaction time to maintenance events

Reporting
'Access to the central information server on demand
'Automatic receiving of reports (KPI, production, assets)
'Facilitated manual data entry on site (e.g. quality lab)

Operator
'Monitoring the machines and production plant
'Take control for special use cases (audit trail advisable)
