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.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Audit logs and logging tools are critical resources whose protection requires correct permission assignments to block unauthorized actions.
Documenting information locations and authorized users enables better protection against unauthorized exposure of sensitive data.
Places configuration items under formal management, enforcing correct permission assignments on critical resources.
Requiring equivalent controls at the alternate storage site prevents unauthorized exposure of sensitive backup data.
Protecting confidentiality of backup information prevents unauthorized exposure of sensitive data stored in backups.
Assessing control effectiveness and providing incident communication channels at alternate sites reduces the likelihood of sensitive information exposure to unauthorized actors.
Requiring protection of the program plan from unauthorized disclosure directly reduces exposure of sensitive security program details and control descriptions.
