EAP-TLS 인증을 사용한 인증서 기반 검증(CLI 절차)
개요
이 구성에서 외부 사용자 인증(RADIUS 서버별)에 대한 사용자 이름과 비밀번호를 사용하고 EAP-TLS 인증 방법을 사용하여 사용자 인증서를 검증합니다.
그림 1과 같이 인터페이스, 영역 및 보안 정책을 포함하여 SRX 시리즈 방화벽의 기본 설정을 완료했다고 가정합니다.

사전 필수 사항에 대한 자세한 내용은 시스템 요구 사항을 참조하십시오.
백엔드 인증으로 구성된 PKI(Public Key Infrastructure)가 있는지 확인합니다. 이 경우 각 클라이언트에 CA의 루트 인증서와 각 클라이언트 디바이스에 사용자 특정 인증서를 설치해야 합니다. 이 시나리오에서는 로컬 인증이 지원되지 않습니다.
SRX 시리즈 방화벽이 기본 시스템 생성 인증서 대신 서명된 인증서 또는 자체 서명 인증서를 사용하는지 확인해야 합니다. Juniper Secure Connect 구성을 시작하기 전에 다음 명령을 실행하여 인증서를 SRX 시리즈 방화벽에 바인딩해야 합니다.
user@host# set system services web-management https pki-local-certificate <cert_name>
예를 들어:
user@host# set system services web-management https pki-local-certificate SRX_Certificate
여기서 SRX_Certificate 자체 서명 인증서입니다.
CLI 빠른 구성
SRX 시리즈 방화벽에서 이 예를 빠르게 구성하려면, 아래 명령을 복사하여 텍스트 파일로 붙여 넣은 다음 모든 라인브러브를 제거하고, 네트워크 구성과 일치하기 위해 필요한 세부 사항을 변경한 다음 명령을 복사하여 [edit] 계층 수준의 CLI에 붙여 넣습니다.
