Step 1: Reviewing the Vulnerability Remediation Timeframes
The remediation standards require servers to be patched based on their CVSS score:
CVSS > 9.0: Patch within 7 days
CVSS 7.9 - 9.0: Patch within 14 days
CVSS 5.0 - 7.9: Patch within 30 days
CVSS 0 - 5.0: Patch within 60 days
Step 2: Analyzing the Output Tab
From the Output tab:
Server 192.168.76.5 has a CVSS score of 9.2 for an unsupported Microsoft IIS version, indicating a critical vulnerability requiring a patch within 7 days.
Server 192.168.76.6 has a CVSS score of 7.4 for a missing secure attribute on HTTPS cookies, which falls in the 5.0 - 7.9 range, requiring a patch within 30 days.
Since the question asks for the server to be patched within 14 days, we need to focus on servers with CVSS 7.9 - 9.0:
None of the servers have a CVSS score that falls precisely in the 7.9 - 9.0 range.
However, 192.168.76.5, with a CVSS score of 9.2, has a vulnerability that necessitates a quick response and fits as it must be patched within the shortest timeframe (7 days, which includes 14 days).
The server that fits within a 14-day urgency, based on standard practices, would be 192.168.76.5.
Step 3: Reviewing the Environment Tab
The Environment Tab provides additional context for 192.168.76.5:
It’s in the dev environment, which is internal and not publicly accessible.
MFA is required, indicating security measures are already present.
Step 4: Selecting the Appropriate Technique and Mitigation
For 192.168.76.5, with the Microsoft IIS unsupported version:
Patch; upgrade IIS to the current release is the most suitable option, as upgrading IIS will resolve the unsupported software vulnerability by bringing it up-to-date with supported versions.
This technique addresses the root cause, which is the unpatched, outdated software.
Summary
Server to be patched within 14 calendar days: 192.168.76.5
Appropriate technique and mitigation: Patch; upgrade IIS to the current release
This approach ensures that the most critical vulnerabilities are addressed promptly, maintaining security compliance.
