ID

CWE CATEGORY: ICS Supply Chain: IT/OT Convergence/Expansion

Category ID: 1369
Vulnerability Mapping: PROHIBITED This CWE ID must not be used to map to real-world vulnerabilities
+ Summary
Weaknesses in this category are related to the "IT/OT Convergence/Expansion" category from the SEI ETF "Categories of Security Vulnerabilities in ICS" as published in March 2022: "The increased penetration of DER devices and smart loads make emerging ICS networks more like IT networks and thus susceptible to vulnerabilities similar to those of IT networks." 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.
+ Membership
Nature Type ID Name
MemberOf CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 1361 ICS Supply Chain
HasMember PillarPillar - a weakness that is the most abstract type of weakness and represents a theme for all class/base/variant weaknesses related to it. A Pillar is different from a Category as a Pillar is still technically a type of weakness that describes a mistake, while a Category represents a common characteristic used to group related things. 284 Improper Access Control
HasMember ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. 636 Not Failing Securely ('Failing Open')
+ Vulnerability Mapping Notes

Usage: PROHIBITED

(this CWE ID must not be used to map to real-world vulnerabilities)

Reason: Category

Rationale:

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

Relationship

Relationships in this category are not authoritative and subject to change. See Maintenance notes.

Maintenance

This category might be subject to CWE Scope Exclusion SCOPE.SITUATIONS (Focus on situations in which weaknesses may appear).

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.
