CompTIA Updated CS0-003 Exam Questions and Answers by maddox

Tocapture and analyze network traffic, the two best tools are:

tcpdump (Option A)– A command-line packet capture tool used for network traffic analysis.

Wireshark (Option D)– A GUI-based network packet analysis tool that provides deep inspection capabilities​.

Option B (SIEM)is forlog aggregationand does notcapturetraffic.

Option C (Vulnerability scanner)identifies weaknesses but does notcapturenetwork traffic.

Option E (Nmap)is used for network discovery and port scanning, not capturing traffic.

Option F (SOAR)automates security processes but does not capture traffic.

Thus,A (tcpdump) and D (Wireshark) are correct, asthey are the best tools for capturing and analyzing anomalous network traffic​.

The analyst will be creating TTPs (Tactics, Techniques, and Procedures). TTPs describe the behavior, methods, and patterns used by attackers during a cyber attack. By focusing on TTPs, the analyst can develop a dynamic detection strategy that identifies malicious activities based on the observed behavior and patterns, rather than relying on static indicators like signatures or IOCs (Indicators of Compromise).

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. References: Cybersecurity Analyst+ - CompTIA, taskhw.exe Windows process - What is it? - file.net, Taskhostw.exe - What Is Taskhostw.exe & Is It Malware? - MalwareTips Forums

The vulnerability that should be patched first, given the above third-party scoring system, is:

TSpirit: Cobain: Yes Grohl: Yes Novo: Yes Smear: No Channing: No

This vulnerability has three out of five metrics marked as Yes, which indicates a high severity level. The metrics Cobain, Grohl, and Novo are more important than Smear and Channing, according to the vulnerability management team. Therefore, this vulnerability poses a greater risk than the other vulnerabilities and should be patched first.
