This chart reveals CVEs affecting Important Manufacturing that was recognized in 2021 advisories which may be used to perform techniques from the MITRE ATT&CK framework ease of studying. Names and definitions of techniques are straight referenced from the MITRE ATT&CK framework.
600 and 13 CVEs recognized in advisories in 2021 are more likely to have an effect on Important Manufacturing environments, 88.8% of them may be leveraged by attackers to create an Affect (to straight or not directly trigger various levels of disruption to ICS tools and the surroundings).
For ICS environments, Affect is a important concern that features harm or disruption to funds, security, human lives, the surroundings, and tools. If we evaluate Affect on operational know-how (OT) with Affect on data know-how (IT), potential Affect from an IT incident will not be almost so broad and is extra restricted to how the attackers can have an effect on knowledge.
Sixty-four level 4 % of these 613 CVEs will be exploited to perform Preliminary Entry. This underscores that getting the door open is a serious focal point and surprisingly straightforward to perform in unsecured techniques.
Moreover, vulnerabilities that may be exploited to Inhibit Response Perform are fairly frequent at 81.9%. Strategies for undertaking this embody disrupting functionalities associated to security, safety, high quality management, and operator intervention. That is one generally discovered means attackers can leverage a single level of failure to trigger critical harm or break the entire system.
Eighty-eight level eight % makes use of Affect, which will be completed with Important Manufacturing-affecting CVEs recognized in 2021 advisories.
it’s vital to notice that when IT is underneath assault, OT may also take collateral harm. Within the Colonial Pipeline incident, their IT infrastructure was attacked by the DarkSide ransomware. Collateral harm compelled them to close down their complete pipeline operation, and the results on their operational know-how started of their IT system.
For ICS operations, Affect can have far-reaching “ripple” results that unfold outward from the purpose of incident.
Partly three, our collection wrap-up, we’ll proceed to dig deeper and consider CVEs that have an effect on important manufacturing based mostly on MITRE’s matrix. We’ll additionally discover frequent ICS-affecting vulnerabilities recognized in 2021.
