Physical protection
Industrial Control Protocols do not offer cryptographic pro-
tections at protocol level, at physical ports and at control-
ler mode switches, leaving them exposed to cybersecurity
risk. Physical security is an important layer of defense in
such cases. The UPS is designed with the consideration
that it would be deployed and operated in a physically se-
cure location.
•
Physical access to the communication lines should be
restricted to prevent any attempts of wiretapping or
sabotage. It is a best practice to use metal conduits
for the communication lines running from one cabinet
to another cabinet.
•
An attacker with unauthorized physical access to the
device could cause serious disruption of the device
functionality. A combination of physical access con-
trols to the location should be used, such as locks,
card readers, and/or guards.
•
The UPS supports the following physical access ports:
RS232, USB and slots for communication cards. Ac-
cess to them must be restricted.
•
Do not connect an unauthorized USB device, CD/DVD
or SD card for any operation (for example, firmware
upgrade, configuration change and boot application
change).
•
Before connecting any portable device through USB,
CD/DVD or SD card slot, scan the device for mal-
wares and viruses.
