Based on the compliance report, I recommend the following changes for each server:
AppServ1: No changes are needed for this server.
AppServ2: Disable or upgrade TLS 1.0 and TLS 1.1 to TLS 1.2 on this server to ensure secure encryption and communication between clients and the server. Update Apache from version 2.4.17 to version 2.4.18 or greater on this server to fix any potential vulnerabilities or bugs.
AppServ3: Downgrade Apache from version 2.4.19 to version 2.4.18 or lower on this server to ensure compatibility and stability with the company's applications and policies. Change the port number from 8080 to either port 80 (for HTTP) or port 443 (for HTTPS) on this server to follow the default port convention and avoid any confusion or conflicts with other services.
AppServ4: Update Apache from version 2.4.16 to version 2.4.18 or greater on this server to fix any potential vulnerabilities or bugs. Change the port number from 8443 to either port 80 (for HTTP) or port 443 (for HTTPS) on this server to follow the default port convention and avoid any confusion or conflicts with other services.

The first step should be to perform a public search for malware reports on taskhw.exe, as this file is suspicious for several reasons: it is located in a non-standard path, it has a high CPU usage, it is signed by an unknown entity, and it is only present on one host. A public search can help to determine if this file is a known malware or a legitimate program. If it is malware, the hunter can then take appropriate actions to remove it and prevent further damage. The other options are either premature or ineffective, as they do not provide enough information to assess the threat level of taskhw.exe.

SIEM (Security Information and Event Management) technology aggregates and analyzes activity from many different resources across your IT infrastructure. The description of correlating information from various sources and triggering notifications aligns with the capabilities of a SIEM system.

User behavior analysis (UBA) is the most effective method for detecting abnormal account activity.
* UBA uses machine learning and behavioral analytics to identify patterns in how users interact with systems. If an employee suddenly logs in from an unusual location or accesses resources outside of their normal behavior, it raises an alert.
* Option A (Malicious command interpretation) is focused on malware analysis, not user behavior.
* Option B (Network monitoring) detects anomalies at the network level, but does not specifically focus on user behaviors.
* Option D (SSL Inspection) is useful for decrypting encrypted traffic, but it does not analyze user activity patterns.

Comprehensive and Detailed Explanation From Exact Extract:
To determine which system to remediate first using only CVSS vectors, the analyst should prioritize the vulnerability that is most severe and most easily exploitable, especially when it is exploitable over the network and requires no privileges and no user interaction.
The Web server has the most dangerous combination of exploitability and impact:
Attack Vector = Network (AV:N) → exploitable remotely over a network
Attack Complexity = Low (AC:L) → no special conditions required
Privileges Required = None (PR:N) → attacker doesn't need credentials
User Interaction = None (UI:N) → no user action required
Impact = High for Confidentiality, Integrity, and Availability (C:H / I:H / A:H) → full compromise potential The Sybex CySA+ Study Guide explains that CVSS provides a 0-10 severity score and that analysts must be able to interpret key metrics like Attack Vector, Attack Complexity, Privileges Required, User Interaction, and Impact.
The All-in-One guide defines Attack Vector and notes that the more remote the vector, the higher the score (Network is remotely exploitable).
And Secbay Press states that organizations use CVSS as a basis for prioritization, typically addressing higher scores first.
Exact extract (Secbay Press): "Organizations often use CVSS scores as a basis for prioritizing vulnerabilities, addressing those with higher scores first." Why the other assets are lower priority than the Web server (based on the vectors) File server (AV:L) is local attack vector, meaning the attacker must already have local access; that generally reduces priority compared to a remotely exploitable (AV:N) issue. (Attack vector definitions and scoring emphasize Network vs Local distinctions.) Mail server (AC:H) requires high attack complexity, lowering exploitability compared to the Web server's AC:L.
Domain controller (PR:R, UI:R) requires privileges and user interaction, which lowers exploitability compared to PR:N/UI:N on the Web server.
Bottom line: The Web server is the most immediately dangerous because it is remotely exploitable (AV:N) with low complexity (AC:L), requires no privileges (PR:N) and no user interaction (UI:N), and has high impact across C/I/A-making it the strongest candidate for first remediation under CVSS-based prioritization.
