AC-16Security and Privacy Attributes

Provide the means to associate {{ insert: param, ac-16_prm_1 }} with {{ insert: param, ac-16_prm_2 }} for information in storage, in process, and/or in transmission; Ensure that the attribute associations are made and retained with the information; Establish the following permitted security and privacy attributes from the attributes defined in [AC-16a](#ac-16_smt.a) for {{ insert: param, ac-16_prm_3 }}: {{ insert: param, ac-16_prm_4 }}; Determine the following permitted attribute values or ranges for each of the established attributes: {{ insert: param, ac-16_odp.09 }}; Audit changes to attributes; and Review {{ insert: param, ac-16_prm_6 }} for applicability {{ insert: param, ac-16_prm_7 }}.

CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-862Missing Authorization11,800+Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
CWE-200Exposure of Sensitive Information to an Unauthorized Actor11,700+Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
CWE-284Improper Access Control8,100+Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
CWE-863Incorrect Authorization4,800+Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.
CWE-732Incorrect Permission Assignment for Critical Resource2,000+Attribute management for resources provides a mechanism to assign and maintain correct permissions based on security labels.
CWE-285Improper Authorization1,700+Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.
CWE-359Exposure of Private Personal Information to an Unauthorized Actor200+Privacy-specific attributes and their controlled association directly reduce exposure of private personal information through missing or incorrect labeling.
CWE-1220Insufficient Granularity of Access Control100+Use of granular security and privacy attributes enables finer access control than coarse permission models alone.
