CVE-2021-47923

Reveals spoofed logon attempts through unexpected previous logon timestamps upon legitimate login.

Training specifically addresses recognizing spoofed communications and phishing that enable authentication bypass.

Requiring verifiable identity evidence at appropriate assurance levels makes it substantially harder for attackers to successfully spoof or impersonate users to obtain accounts.

Unique device authentication makes successful spoofing of device identity substantially more difficult to achieve.

Unique identification of non-organizational users reduces the feasibility of authentication bypass by spoofing.

Unique identification and authentication of services before communications makes spoofing of service identities substantially harder.

Isolated trusted path ensures the user interacts only with genuine system components, preventing spoofing of authentication interfaces or prompts.

Directly counters DNS response spoofing by requiring cryptographic origin authentication artifacts from the authoritative source.
