서비스 계층 보안

The services security layer addresses security of services that service providers provide to their customers. These services range from basic transport and connectivity to service enablers like those that are necessary for providing Internet access (e.g., AAA services, dynamic host configuration services, domain name services, etc.) to value-added services such as freephone service, QoS, VPN, location services, instant messaging, etc. The services security layer is used to protect the service providers and their customers, both of which are potential targets of security threats. For example, the attackers may attempt to deny the service provider's ability to offer the services, or they may attempt to disrupt service for an individual customer of the service provider (e.g., a corporation).

서비스에 대한 보안으로 접속과 전송은 물론 인터넷전화나 VPN, 메세징서비스와 같이 인터넷 접속을 제공할 필요가 있는 서비스업자도 이에 포함된다. 서비스 계층 보안은 인터넷 서비스 사업자와 사용자 모두에게 필요한 보안으로 누군가가 서비스를 취소하거나 방해하는 것으로부터 보호한다.
