Let's get physical: the SAE g-32 solution
for the cyber-physical menace
On June 2, 2022, SAE
International's G-32 Cyber Physical
Systems Security Committee
published its first joint Aerospace
and Automotive standard, JA7496:
Cyber Physical Systems Security
Engineering Plan. The new
standard is intended for broad
industry use for both commercial
and defense applications along
with other high reliability and/or
critical systems in aerospace,
transportation, medicine, and
finance.
According to Judith Ritchie,
Director, Government and
Industry Affairs - Aerospace for
SAE International: " Before
security risks of cyber physical
systems (CPS) can successfully
be assessed and managed, it is
necessary to clearly understand
the cyber landscape and define
the problem statement. Threats
to cybersecurity cover a broad
range of attack vectors with the
integration of complex hardware,
software, and firmware
supporting the cyber physical
system. Cyber physical system
security begins with the
electronic parts, assemblies,
software, and firmware that

connected to input/output (i/O) modules to a test network. Algorithms
scanned the network for cyberattacks through data packets transferred over
the Modbus/TCP protocol.
make up the system. "
" Attack vectors can be introduced trough hostile
code at the time of software or firmware updates, "
she added. " Cyber physical systems are susceptible
to compromising attacks due to counterfeit
tampered electronic parts with embedded malware
or hardware Trojans, or legitimate components with
vulnerabilities due to the design. The risk analysis
expands beyond the construction to the entire
system. "
The JA7496 standard provides the framework for a
systems engineering approach to standardization of
cyber physical systems security. The following goals
are addressed:
* Characterize CPS risk, assess vulnerabilities, and
recommend mitigating actions
* Advance knowledge of how weaknesses in CPS are
introduced and exploited
