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.

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.
