name: GAA
full_form: Generic Authentication Architecture
context: Figure 4-1 depicts the GAA related functionalities in the terminal. In relation to the GAA architecture, the GAA server communicates with the BSF server over Ub reference point, and with the UICC through the relevant device drivers, for example. The GAA client communicates over the network with a NAF server and the GAA server to obtain the NAF specific GAA credentials. When a NAF server requests a GAA client to authenticate itself with GAA credentials, the client communicates with the GAA server for GAA credentials specific to that NAF. Figure 4-1 GAA related modules in terminal The inherent feature of open platforms is that new applications can be installed to the terminal. In relation to GAA, this poses a security threat when a malicious application is installed in a type of terminal that does not protect GAA related functionalities. The GAA related security threats are as follows: - A malicious application can access the UICC directly and therefore can function as a GAA server,
description: Generic Authentication Architecture (GAA) is a technology standard that provides secure authentication mechanisms for various network applications and services in telecommunications. It enables secure communication between servers, clients, and other network entities by verifying identities and authorizing access.
explanation: GAA is classified as an 'Authentication Technology' because its primary function is to establish trust and verify identities within a telecommunications network. It directly addresses the security aspect of authentication, ensuring only authorized users or devices can access specific resources.
