CompTIA CS0-003 Dumps Questions Answers

Comprehensive and Detailed Explanation:

Key Performance Indicators (KPIs)track the effectiveness of a security program, providing measurable insights intovulnerability detection, patching efficiency, and risk reduction. This makes KPIs ideal for executive dashboards​.

Option B (MOU - Memorandum of Understanding)refers toagreements between parties, not performance tracking.

Option C (SLO - Service Level Objective)defines operationaltargetsbut is nota tracking metric.

Option D (SLA - Service Level Agreement)defines expectations betweenservice providers and clients, not security metrics.

Thus,A (KPI) is the correct answer, asKPIs provide actionable insights into security effectiveness​.

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.

Comprehensive Detailed Explanation:To match the mitigation criteria, we analyze each machine’s CVSS (Common Vulnerability Scoring System) attributes:

Attack Vector (AV): N for network (matches the requirement of network-based attack).

Attack Complexity (AC): L for low (meets the requirement for low complexity).

Privileges Required (PR): N for none (indicating no privileges are needed).

User Interaction (UI): N for none (matches the requirement that no user action is needed).

Confidentiality (C), Integrity (I), and Availability (A): Requires high confidentiality and availability with low integrity.

From these criteria:

Computer1 requires user interaction (UI:R), which disqualifies it.

Computer2 has a local attack vector (AV:L), which disqualifies it for a network-based attack.

Computer3 has a high attack complexity (AC:H), which does not meet the low complexity requirement.

Computer4 meets all criteria: network attack vector, low complexity, no privileges, no user interaction, and appropriate confidentiality, integrity, and availability levels.

Thus, Computer4 is the correct answer.
