CPTIA Exam Dumps : CREST Practitioner Threat Intelligence Analyst

In the scenario described, Dickson is performing an active assessment. This type of vulnerability assessment involves using automated tools to actively scan and probe the network for identifying hosts, services, and vulnerabilities. Unlike passive assessments, which rely on monitoring network traffic without direct interaction with the targets, active assessments engage directly with the network infrastructure to discover vulnerabilities, misconfigurations, and other security issues by sending data to systems and analyzing the responses. This approach provides a more immediate and detailed view of the security posture but can also generate detectable traffic that might be noticed by defensive systems or affect the performance of live systems.

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.

The correct sequence to examine the originating IP address of emails involves first accessing the email's header to locate the IP address, then using external resources to investigate that address further. The steps are as follows:

Step 2:Open the email to trace and find its header. This is the initial step because the header contains valuable information about the email's journey across the internet, including the originating IP address.

Step 3:Collect the IP address of the sender from the header of the received mail. This detail is crucial for the next steps in the investigation.

Step 1:Search for the IP in the WHOIS database. This database can provide information about the owner of the IP address, including the ISP and sometimes the geographic location.

Step 4:Look for the geographic address of the sender in the WHOIS database. With the IP address information obtained from the WHOIS search, the geographic location or the originating country of the email can often be deduced, contributing to the analysis of the email's legitimacy.

References:The process of analyzing email headers to trace originating IP addresses and further investigating those addresses is a common practice in incident response, covered under the digital forensics and email analysis topics within the CREST CPTIA curriculum by EC-Council.
