ICS VULNERABILITIES RISE AS RELIANCE
ON REMOTE ACCESS TO INDUSTRIAL
NETWORKS INCREASES DURING COVID-19
More than 70% of industrial
control system (ICS) vulnerabilities
disclosed in the first half of
2020 can be exploited remotely,
highlighting the importance of
protecting Internet-facing ICS
devices and remote access
connections. This is according to
the inaugural Biannual ICS Risk
& Vulnerability Report, by Claroty,
a global leader in Operational
Technology (OT) security.
The report comprises the Claroty
research team’s assessment of 365
ICS vulnerabilities published by the
National Vulnerability Database (NVD)
and 139 ICS advisories issued by
the Industrial Control Systems Cyber
Emergency Response Team (ICS-
CERT) during 1H 2020, affecting
53 vendors. The research team
discovered 26 of the vulnerabilities
included in this data set.
Compared to 1H 2019, ICS
vulnerabilities published by the
NVD increased by 10.3% from 331,
We recognised
the critical need to
understand, evaluate
and report on the
comprehensive ICS
risk and vulnerability
landscape.
while ICS-CERT advisories increased
by 32.4% from 105. More than 75% of
vulnerabilities were assigned high or
critical Common Vulnerability Scoring
System (CVSS) scores.
“There is a heightened awareness of
the risks posed by ICS vulnerabilities
and a sharpened focus among
researchers and vendors to identify
and remediate these vulnerabilities as
effectively and efficiently as possible,”
