Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Defining account types, requiring approvals for creation, specifying authorizations, monitoring usage, and reviewing accounts directly prevents improper access control by ensuring only authorized accounts exist and are used.
Provides a tamperproof, always-invoked, and verifiable mechanism to enforce access control policies.
By mandating division of duties across roles, the control enforces proper privilege management and prevents a single entity from controlling an entire sensitive process.
Implements core proper privilege management by restricting to only required rights.
The awareness and training policy mandates training on access control practices, directly reducing the likelihood of improper access control weaknesses being introduced or exploited.
Training covers proper privilege management practices, making incorrect privilege assignments less likely.
