Difficulty: EasyAAA Framework and Authentication Methods

Match each core component of the AAA security framework to its corresponding network security function.

  • AuthenticationVerifying the identity of a user or device requesting network access.
  • AuthorizationDetermining the specific permissions and access privileges granted to a user.
  • AccountingTracking user activity, session duration, and data usage for security auditing.

Answer

Authentication matches with identity verification; Authorization matches with permission enforcement; Accounting matches with activity tracking and auditing.
Authentication establishes and confirms entity identity, Authorization controls accessible operations and services, and Accounting collects operational metrics and session logs for security audits.

Step-by-Step Solution

1
Analyze the function of Authentication in network access management.
Authentication verifies identity credentials.
Authentication is the first pillar of AAA, proving the identity of the entity requesting access.
2
Analyze the function of Authorization in network access management.
Authorization defines privileges and access bounds.
Once identity is proven, authorization enforces rules on what the entity is allowed to do.
3
Analyze the function of Accounting in network access management.
Accounting records session history and resource usage.
Accounting creates an audit trail of user activity and resource consumption.
