ICS Dependencies (& Architecture): External Physical Systems

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.
