Zorluk: KolayAuthentication, Authorization, and Accounting (AAA)

Match each network access control scenario on the left with the corresponding pillar of the Authentication, Authorization, and Accounting (AAA) framework (or Identification) on the right.

  • A user enters their account username into a system prompt prior to submitting credentials.Identification
  • A server validates a user's password and one-time passcode (OTP) against a central database.Authentication
  • A security policy engine checks a user's role and grants read-only access to a specific database.Authorization
  • A gateway logs session start and end times, command history, and total byte counts for auditing.Accounting

Cevap

Entering a username corresponds to Identification. Validating passwords and OTP codes corresponds to Authentication. Enforcing role-based access permissions corresponds to Authorization. Recording session duration and bandwidth consumption corresponds to Accounting.
Each phase of the access control workflow fulfills a distinct AAA pillar: Identification claims identity, Authentication verifies credentials, Authorization enforces permissions, and Accounting logs activity metrics.

Adım Adım Çözüm

1
Analyze the first scenario (entering a username).
Entering a username is the assertion of identity before verification, matching Identification.
Identification establishes who the user claims to be.
2
Analyze the second scenario (validating passwords and OTP codes).
Verifying secret credentials proves the identity claim, matching Authentication.
Authentication verifies proof of identity.
3
Analyze the third scenario (checking roles to grant database permissions).
Restricting access based on policies matches Authorization.
Authorization defines what actions an authenticated user is permitted to perform.
4
Analyze the fourth scenario (logging session duration and byte counts).
Recording usage metrics and session logs matches Accounting.
Accounting tracks resource usage and creates audit logs for oversight.
