Cybersecurity vulnerabilities that are relevant to the delivery of the function are mitigated, at least in an ad hoc manner
Context and Guidance: The organisation responds to vulnerabilities identified by credible information sources (e.g., government agencies, the software vendor) and takes steps to mitigate those vulnerabilities if they may affect the delivery of services. Vulnerability announcements may include criticality ratings (such as high, medium, low). These should be considered in the context of the overall environment. Even low-scoring vulnerabilities may be relevant and have a significant potential impact when assessed against your IT or OT environment. Response might involve, for example, implementing mitigating controls, applying cybersecurity patches, or tracking patching levels and operating system versions of devices. Advanced cybersecurity techniques such as threat hunting and active defense can provide in-depth information about the IT and OT environment that supports the determination of the relevance of a vulnerability to the organisation. It is important to note that implementation of new compensating controls may require allocation of additional resources, such as people, funding, and tools, beyond the current cybersecurity program budget.
