Steve works as an analyst in a UK-based firm. He was asked to perform network monitoring to find any evidence of compromise. During the network monitoring, he came to know that there are multiple logins from different locations in a short time span. Moreover, he also observed certain irregular log in patterns from locations where the organization does not have business relations. This resembles that somebody is trying to steal confidential information.
Which of the following key indicators of compromise does this scenario present?
A. Unexpected patching of systems
B. Unusual outbound network traffic
C. Unusual activity through privileged user account
D. Geographical anomalies
正解：D
解説：
The scenario described by Steve's observations, where multiple logins are occurring from different locations in a short time span, especially from locations where the organization has no business relations, points to
'Geographical anomalies' as a key indicator of compromise (IoC). Geographical anomalies in logins suggest unauthorized access attempts potentially made by attackers using compromised credentials. This is particularly suspicious when the locations of these logins do not align with the normal geographical footprint of the organization's operations or employee locations. Monitoring for such anomalies can help in the early detection of unauthorized access and potential data breaches.References:

Sam works as an analyst in an organization named InfoTech Security. He was asked to collect information from various threat intelligence sources. In meeting the deadline, he forgot to verify the threat intelligence sources and used data from an open-source data provider, who offered it at a very low cost. Through it was beneficial at the initial stage but relying on such data providers can produce unreliable data and noise putting the organization network into risk.
What mistake Sam did that led to this situation?
A. Sam used unreliable intelligence sources.
B. Sam did not use the proper standardization formats for representing threat data.
C. Sam used data without context.
D. Sam did not use the proper technology to use or consume the information.
正解：D

Cybersol Technologies initiated a cyber-threat intelligence program with a team of threat intelligence analysts. During the process, the analysts started converting the raw data into useful information by applying various techniques, such as machine-based techniques, and statistical methods.
In which of the following phases of the threat intelligence lifecycle is the threat intelligence team currently working?
A. Processing and exploitation
B. Dissemination and integration
C. Planning and direction
D. Analysis and production
正解：B
質問 # 37
Tim is working as an analyst in an ABC organization. His organization had been facing many challenges in converting the raw threat intelligence data into meaningful contextual information. After inspection, he found that it was due to noise obtained from misrepresentation of data from huge data collections. Hence, it is important to clean the data before performing data analysis using techniques such as data reduction. He needs to choose an appropriate threat intelligence framework that automatically performs data collection, filtering, and analysis for his organization.
Which of the following threat intelligence frameworks should he choose to perform such task?
A. HighCharts
B. SIGVERIF
C. Threat grid
D. TC complete
正解：D
質問 # 38
During the process of threat intelligence analysis, John, a threat analyst, successfully extracted an indication of adversary's information, such as Modus operandi, tools, communication channels, and forensics evasion strategies used by adversaries.
Identify the type of threat intelligence analysis is performed by John.
A. Technical threat intelligence analysis
B. Operational threat intelligence analysis
C. Tactical threat intelligence analysis
D. Strategic threat intelligence analysis
正解：C
解説：
Tactical threat intelligence analysis focuses on the immediate, technical indicators of threats, such as the tactics, techniques, and procedures (TTPs) used by adversaries, their communication channels, the tools and software they utilize, and their strategies for evading forensic analysis. This type of analysis is crucial for operational defenses and is used by security teams to adjust their defenses against current threats. Since John successfully extracted information related to the adversaries' modus operandi, tools, communication channels, and evasion strategies, he is performing tactical threat intelligence analysis. This differs from strategic and operational threat intelligence, which focus on broader trends and specific operations, respectively, and from technical threat intelligence, which deals with technical indicators like malware signatures and IPs.References:
