ate and maintain plants remotely over
the last year has led to new initiatives
that ensure remote access is carried
out securely, " says ABB's Dickinson.
" Many of the vulnerabilities exploited
by attackers relate to insecure remote
access setup, so it's important
that an appropriate level of security is
embedded in your digital and remoteaccess
solutions, " he cautions.
Other product developments
ABB has developed a Secure Reference
Architecture (Figure 3) and
Cyber
Security
Risk
Assessment
Service, both based on IEC 62443,
that couples together best practice
approaches to securing industrial
distributed control systems (DCS).
" We work strategically with our customers
to identify both their risk exposure
and assess the maturity of
their system security and security
management practices. This enables
the identification of appropriate security
levels required for each system
in order to mitigate cyber security
risk to an acceptable level that corresponds
to the organization's risk
appetite and regulatory compliance
requirements, " explains Dickinson.
This approach ensures optimal return
on investment of cybersecurity
improvement programs by ensuring
all investments are tied to risk, Dickinson
continues. Implementing the
recommended security controls to
achieve the identified security level
will significantly reduce risk, but not
eliminate it completely. " To address
the residual risk, ABB has developed
an event-monitoring service to help
our customers effectively monitor
their control systems and detect
when an attacker has been successful
in targeting your systems in order
to respond quickly and effectively
and thus limit the damage they have
on a system, " he says.
Meanwhile, Honeywell continues
to invest in OT cybersecurity products
and services, says Tindill. Some
recent new offerings include Honeywell
Forge Managed Security Services
with Advanced Monitoring &
Incident Response. Scheduled to be
launched at the end of March, this offering
is configured especially for OT
environments. " This 24/7-managed
security service combines automated
analytics with the know-how of certified
cybersecurity professionals to
help identify, mitigate and manage
cybersecurity threats, " says Tindill.
Other
recent
offerings
include
Honeywell Forge Cybersecurity
Suite, the latest release of industry
proven software that helps users
better manage the operations of OTcentric
cybersecurity with improved
asset discovery, risk and compliance
monitoring and more. Also recently
introduced is PCN Hardening
Services. " Configured especially for
OT networks, this service offers a
method of better securing process
control systems and network devices
by applying elevated security
configurations to existing components, "
says Tindill.
