사전 공유 키를 사용한 로컬 사용자 인증(CLI 절차)
개요
이 구성에서는 로컬 사용자 인증에 사용자 이름과 암호를 사용합니다. 이 구성 옵션을 사용하면 방화벽 관리자와 상호 작용하지 않고는 자격 증명을 변경하거나 복구할 수 없으므로 이 인증 방법을 사용하지 않는 것이 좋습니다. 대신 RADIUS 방법을 사용한 외부 사용자 인증을 사용하는 것이 좋습니다.
그림 1에 나와 있는 것처럼 인터페이스, 영역, 보안 정책을 포함한 SRX 시리즈 방화벽의 기본 설정을 완료했다고 가정합니다.
그림 1: 토폴로지
필수 구성 요소에 대한 자세한 내용은 시스템 요구 사항을 참조하십시오.
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 는 자체 서명된 인증서입니다.
CLI 빠른 구성
SRX 시리즈 방화벽에서 이 예제를 빠르게 구성하려면 다음 명령을 복사하여 텍스트 파일에 붙여 넣고, 줄 바꿈을 제거하고, 네트워크 구성과 일치시키는 데 필요한 세부 정보를 변경한 다음, 명령을 복사하여 [edit] 계층 수준에서 CLI에 붙여넣습니다.
