COS는 지원되는 모든 COS 출시 버전에 대한 머신이 읽을 수 있는 구조화된 데이터 세트인 Open Vulnerability and Assessment Language(OVAL) 취약점 피드를 제공합니다. 피드를 사용하여 COS 시스템에 설치된 패키지의 보안 문제를 평가할 수 있습니다.
gs://cos-oval-vulnerability-feed에서 OVAL 피드에 액세스할 수 있으며,
피드는 이미지에 설치된 패키지를 나열하는 cos-package-info.json 파일에 따라 달라집니다. 이 파일은 VM 인스턴스의 /etc 디렉터리에 있습니다.
OVAL 피드를 사용하여 COS VM 인스턴스 스캔
OVAL 피드를 사용하여 모든 COS 인스턴스를 스캔할 수 있습니다. 예를 들어 COS-109 이미지를 실행하는 인스턴스를 스캔하려는 경우를 가정해 보겠습니다.
인스턴스의 OVAL 피드를 다운로드합니다. 올바른 마일스톤을 선택해야 합니다.
현재 예시의 경우 109입니다.

You can use the\nfeed to evaluate packages installed on a COS system for security issues.\n\nYou can access the OVAL feed at `gs://cos-oval-vulnerability-feed`.\nThe feed depends on the `cos-package-info.json` file, which lists installed packages on an\nimage. This file is located at `/etc` directory on your VM instances.\n\nScanning COS VM instances with Oval feed\n----------------------------------------\n\nYou can use the OVAL feed to scan any COS instance. For example, assume you want to scan\nan instance running the `COS-109` image:\n\n1. Download the Oval feed for your instance. Make sure you choose the correct milestone.\n For the current example, it is 109:\n\n gcloud storage cp gs://cos-oval-vulnerability-feed/cos-109.oval.xml.tar.gz .\n\n2. Extract the downloaded Oval feed:\n\n tar xf cos-109.oval.xml.tar.gz\n\n3. Copy `cos-package-info.json` from your VM instance, in this case `my-cos-instance`:\n\n gcloud compute scp my-cos-instance:/etc/cos-package-info.json .\n\n4. Use your preferred Security Content Automation Protocol (SCAP) compliant tool that can process Oval feed. In this case, we use `OpenSCAP`:\n\n oscap oval eval --report report.html cos-109.oval.xml\n\nNote that the `cos-package-info.json` file and the COS Oval feed need to be in the same\ndirectory. If not, update the path of the `cos-package-info.json` in the COS Oval feed file.\n\nHow to fix vulnerabilities reported by the scanner\n--------------------------------------------------\n\nThe feed lists all the vulnerabilities fixed in the latest COS image. As such,\nyou can fix all open vulnerabilities reported by the scanner on your system by\nupdating to the latest COS image for that particular milestone."]]
