Zorluk: Çok zorAuthentication, Authorization, and Accounting (AAA)

Match each enterprise identity and access management scenario on the left with the corresponding core AAA phase or concept on the right.

  • An employee enters a User Principal Name (UPN) at a web portal login prompt prior to presenting any credentials.Identification
  • An identity provider validates a user's FIDO2 WebAuthn asymmetric key signature and hardware token PIN during session initialization.Authentication
  • A security policy engine checks a user's SAML 2.0 role attributes and dynamic network risk score against an Access Control List (ACL) to grant microsegment access.Authorization
  • A central network service logs TACACS+ session start/stop timestamps, executed CLI commands, and total bytes transferred by an administrator.Accounting

Cevap

Entering a User Principal Name maps to Identification. Validating FIDO2 signatures and PINs maps to Authentication. Evaluating SAML role attributes against ACLs maps to Authorization. Logging session timestamps and executed commands via TACACS+ maps to Accounting.
Each scenario represents a distinct stage in identity and access management: Identification is claiming an identity (entering a UPN); Authentication is proving that identity (validating FIDO2 keys and PINs); Authorization is determining allowable actions (checking SAML attributes against ACLs); and Accounting is recording session data and actions for audit logs (logging TACACS+ execution details).

Adım Adım Çözüm

1
Analyze the first scenario (entering UPN at a prompt).
The subject is claiming who they are without providing proof yet.
Claiming an identity before credential verification is the Identification phase.
2
Analyze the second scenario (validating FIDO2 key signatures and PINs).
The system is verifying the truth of the claimed identity using cryptographic keys and factors.
Proving identity using verification factors is the Authentication phase.
3
Analyze the third scenario (evaluating SAML roles and risk scores against ACLs).
The system is determining what permissions and privileges the authenticated user has.
Enforcing access policies and granting resource rights is the Authorization phase.
4
Analyze the fourth scenario (logging TACACS+ timestamps, commands, and bandwidth).
The system is tracking user activity and resource utilization for historical auditing.
Recording actions, resource usage, and session metrics is the Accounting phase.
