CWE Name CVEs Why this control addresses it
CWE-200Exposure of Sensitive Information to an Unauthorized Actor10,204Requiring equivalent controls at the alternate storage site prevents unauthorized exposure of sensitive backup data.
CWE-284Improper Access Control4,832Mandating equivalent access controls ensures the alternate site does not introduce improper access control weaknesses for backups.
CWE-732Incorrect Permission Assignment for Critical Resource1,824Requiring equivalent controls prevents incorrect permission assignments on critical backup resources at the alternate site.
CWE-285Improper Authorization1,230Ensuring equivalent authorization at the alternate site reduces the ability to exploit improper authorization for retrieving backup information.
CWE-922Insecure Storage of Sensitive Information421Establishing an alternate site with equivalent protections directly mitigates insecure storage of sensitive backup information.
