Common Weakness Enumeration

CWE-1367

Grouping Prohibited

ICS Dependencies (& Architecture): External Physical Systems

Status: Incomplete

API response cwe.mitre.org

Weaknesses in this category are related to the "External Physical Systems" category from the SEI ETF "Categories of Security Vulnerabilities in ICS" as published in March 2022: "Due to the highly interconnected technologies in use, an external dependency on another physical system could cause an availability interruption for the protected system." Note: members of this category include "Nearest IT Neighbor" recommendations from the report, as well as suggestions by the CWE team. These relationships are likely to change in future CWE versions.

Grouping entries organize the catalogue and should not be used to map the root cause of a vulnerability.

Mapping guidance

This entry is a Grouping. Using groupings for mapping has been discouraged since 2019. They are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves.

Maintenance

This category was created in CWE 4.7 to facilitate and illuminate discussion about weaknesses in ICS with [REF-1248] as a starting point. After the release of CWE 4.9 in October 2022, this has been under active review by members of the "Boosting CWE" subgroup of the CWE-CAPEC ICS/OT Special Interest Group (SIG). Relationships are still subject to change. In addition, there may be some issues in [REF-1248] that are outside of the current scope of CWE, which will require consultation with many CWE stakeholders to resolve.
