CPTIA Exam Dumps : CREST Practitioner Threat Intelligence Analyst

Wireshark is a widely used network protocol analyzer that helps in capturing and interactively browsing the traffic on a network. It is an essential tool for incident responders like Eric who are developing incident-handling plans and procedures. By analyzing network traffic, Wireshark allows users to see what is happening on their network at a microscopic level, making it invaluable for troubleshooting network problems, analyzing security incidents, and understanding network behavior. Whois is used for querying databases that store registered users or assignees of an Internet resource. Burp Suite is a tool for testing web application security, and FaceNiff is used for session hijacking within a WiFi network, which makes Wireshark the best choice for analyzing network traffic.References:CREST materials often reference Wireshark as a fundamental tool for network analysis, crucial for incident handlers in the analysis phase of incident response.

An Intrusion Prevention System (IPS) device placed inline is best suited to block attacks on a network actively. Being inline allows the IPS to analyze and take action on the traffic as it passes through the device, effectively preventing malicious traffic from reaching its target. The IPS can detect and block a wide range of attacks in real-time by using various detection methods, such as signature-based detection, anomaly detection, and policy-based detection. Unlike Host-based Intrusion Prevention Systems (HIPS), web proxies, or load balancers, an inline IPS is specifically designed to inspect and act on incoming and outgoing network traffic to prevent attacks before they reach network devices or applications.References:The Incident Handler (CREST CPTIA) certification materials discuss network security controls and emphasize the role of intrusion prevention systems in protecting networks against threats.

Bob is in the Investigation phase of the forensic investigation process. This phase involves the detailed examination and analysis of the collected evidence to identify the source of the crime and the perpetrator behind the incident. It is a crucial step that follows the acquisition and preservation of evidence, where the incident responder applies various techniques and methodologies to analyze the evidentiary data. This analysis aims to uncover how the cybercrime was committed, trace the activities of the culprit, and gather actionable intelligence to support legal actions and prevent future incidents.References:The CREST materials discuss the stages of a forensic investigation, emphasizing the investigation phase as the point at which the incident responder analyzes evidence to draw conclusions about the incident's specifics.
