Likely Mitigating Controls AI

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.

addresses: CWE-522

Training instructs users on protecting credentials from disclosure or unauthorized access.

addresses: CWE-522

Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.

addresses: CWE-522

Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.

addresses: CWE-522

Rules of behavior include credential protection and non-sharing requirements, reducing exposure of insufficiently protected credentials.

addresses: CWE-522

Terminating or revoking credentials stops use of insufficiently protected or lingering credentials post-termination.

addresses: CWE-522

Requiring confidentiality/integrity protection for stored credentials directly mitigates insufficiently protected credentials on disk or in configuration stores.

addresses: CWE-522

Credentials or keys delivered out-of-band are not exposed to interception or inadequate protection on the main transport.

PR.DS-01 full match
prevents

Encrypting data-at-rest fully prevents insecure credential storage while only partially satisfying the broader data-protection outcome.

PR.DS-02 full match
prevents

Encrypting data-in-transit fully prevents interception of credentials in motion while only partially satisfying the broader data-protection outcome.

PR.AA-01 mostly match
prevents

Credential management practices directly reduce insecure storage/transmission but do not guarantee encryption or transport protection.

PR.AA-04 mostly match
prevents

Protecting identity assertions covers conveyance of credentials but is narrower than full credential lifecycle protection.

PR.AA-03 partial match
prevents

Authentication policies can enforce stronger credential handling yet address only verification, not storage or transit protection.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.

prevents

Protecting secret and private keys against disclosure and unauthorized use decreases the exposure of credentials that are stored or transmitted in recoverable form.

prevents

Forbidding clear-text transmission and display of passwords, plus the use of stronger alternatives to passwords, prevents credentials from being obtained or reused by attackers.

prevents

Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.

prevents

Contractual clauses that survive termination help ensure that credentials and other secrets are not retained or misused after employment ends.

prevents

Regular reminders about password security and personal accountability make users less likely to store or transmit credentials in cleartext or other unprotected forms.
