A security analyst needs to identify an asset that should be remediated based on the following information: File Server CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H/, Web Server CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/, Mail Server CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/, Domain Controller CVSS:3.1/AV:N/AC:L/PR:R/UI:R/S:U/C:H/I:H/A:H/. Which of the following assets should the analyst remediate first?

The mail server has a high criticality rating for confidentiality, integrity, and availability, but the web server's criticality ratings are even higher. Therefore, the mail server should not be the first asset to be remediated based on the given information.

The domain controller has high criticality ratings for confidentiality, integrity, and availability, but it is not as critical as the web server based on the provided CVSS metrics. Therefore, the domain controller should not be the first asset to be addressed for remediation.

The file server has a lower criticality rating for confidentiality, integrity, and availability compared to the web server. While it is important to address vulnerabilities in the file server, the web server poses a higher risk based on the given information.
