4 CYBER-SECURITY IMPLEMENTATION
The Alstom Grid IEDs have always been and will continue to be equipped with state-of-the-art security
measures. Due to the ever-evolving communication technology and new threats to security, this requirement
is not static. Hardware and software security measures are continuously being developed and implemented
to mitigate the associated threats and risks.
This section describes the current implementation of cyber-security. This is valid for the release of platform
software to which this manual pertains. This current cyber-security implementation is known as Cyber-
security Phase 1.
At the IED level, these cyber-security measures have been implemented:
● NERC-compliant default display
● Four-level access
● Enhanced password security
● Password recovery procedure
● Disabling of unused physical and logical ports
● Inactivity timer
● Security events management
External to the IEDs, the following cyber-security measures have been implemented:
● Antivirus
● Security patch management
4.1 NERC-COMPLIANT DISPLAY
For the device to be NERC-compliant, it must provide the option for a NERC-compliant default display. The
default display that is implemented in our cyber-security concept contains a warning that the IED can be
accessed by authorised users. You can change this if required with the User Banner
setting in the
SECURITY CONFIG column.
ACCESS ONLY FOR
AUTHORISED USERS
HOTKEY
If you try to change the default display from the NERC-compliant one, a further warning is displayed:
DISPLAY NOT NERC
COMPLIANT OK?
The default display navigation map shows how NERC-compliance is achieved with the product's default
display concept.
