- A. CVSS
- B. Scope
- C. Weaponization
- D. Asset value
Answer: C
Explanation:
Weaponization is a factor that describes how an adversary develops or acquires an exploit or payload that can take advantage of a vulnerability and deliver a malicious effect. Weaponization can increase the severity or impact of a vulnerability, as it makes it easier or more likely for an attacker to exploit it successfully and cause damage or harm. Weaponization can also indicate the level of sophistication or motivation of an attacker, as well as the availability or popularity of an exploit or payload in the cyber threat landscape. In this case, an older CVE with a vulnerability score of 7.1 was elevated to a score of 9.8 due to a widely available exploit being used to deliver ransomware. This indicates that weaponization was the reason for this escalation.

A security team is concerned about recent Layer 4 DDoS attacks against the company website. Which of the following controls would best mitigate the attacks?
- A. Deploy an IPS in the perimeter network.
- B. Block the attacks using firewall rules.
- C. Implement a load balancer.
- D. Roll out a CDN.
Answer: D
Explanation:
Rolling out a CDN is the best control to mitigate the Layer 4 DDoS attacks against the company website. A CDN is a Content Delivery Network, which is a system of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server. A CDN can help protect against Layer 4 DDoS attacks, which are volumetric attacks that aim to exhaust the network bandwidth or resources of the target website by sending a large amount of traffic, such as SYN floods, UDP floods, or ICMP floods. A CDN can mitigate these attacks by distributing the traffic across multiple servers, caching the web content closer to the users, filtering out malicious or unwanted traffic, and providing scalability and redundancy for the website12.

An analyst is reviewing system logs while threat hunting:
Which of the following hosts should be investigated first?
- A. PC4
- B. PC5
- C. PC1
- D. PC3
- E. PC2
Answer: D
Explanation:
From the logs, PC3 shows outlook.exe spawning excel.exe at 1:15 PM, and later excel.exe spawning procdump.exe at 1:16 PM. This is highly suspicious because outlook.exe should not normally launch Excel, and procdump.exe is often used by attackers to dump process memory, which is a common technique in credential theft.
* PC1: Running expected Windows processes (wininit.exe spawning services.exe and lsass.exe).
* PC2: Running a browser process (chrome.exe) from explorer.exe, which is normal.
* PC3: Highly suspicious behavior (Excel spawning procdump.exe).
* PC4: Running mstsc.exe (Remote Desktop) from explorer.exe, which is expected.
* PC5: Running Firefox from explorer.exe, which is normal.
Thus, PC3 should be prioritized for investigation due to its potential involvement in credential theft.
NEW QUESTION # 244
During an incident, analysts need to rapidly investigate by the investigation and leadership teams. Which of the following best describes how PII should be safeguarded during an incident?
- A. Implement data encryption and create a standardized procedure for deleting data that is no longer needed.
- B. Ensure permissions are limited in the investigation team and encrypt the data.
- C. Ensure that permissions are open only to the company.
- D. Implement data encryption and close the data so only the company has access.
Answer: B
Explanation:
The best option to safeguard PII during an incident is to ensure permissions are limited in the investigation team and encrypt the data. This is because limiting permissions reduces the risk of unauthorized access or leakage of sensitive data, and encryption protects the data from being read or modified by anyone who does not have the decryption key. Option A is not correct because closing the data may hinder the investigation process and prevent collaboration with other parties who may need access to the data. Option C is not correct because deleting data that is no longer needed may violate legal or regulatory requirements for data retention, and may also destroy potential evidence for the incident. Option D is not correct because opening permissions to the company may expose the data to more people than necessary, increasing the risk of compromise or misuse.

NEW QUESTION # 247
Which of the following makes STIX and OpenloC information readable by both humans and machines?
- A. OVAL
- B. XML
- C. AXII
- D. URL
Answer: B
Explanation:
The correct answer is A. XML.
STIX and OpenloC are two standards for representing and exchanging cyber threat intelligence (CTI) information. STIX stands for Structured Threat Information Expression and OpenloC stands for Open Location and Identity Coordinates. Both standards use XML as the underlying data format to encode the information in a structured and machine-readable way. XML stands for Extensible Markup Language and it is a widely used standard for defining and exchanging data on the web. XML uses tags, attributes, and elements to describe the structure and meaning of the data. XML is also human-readable, as it uses plain text and follows a hierarchical and nested structure.
XML is not the only format that can be used to make STIX and OpenloC information readable by both humans and machines, but it is the most common and widely supported one. Other formats that can be used include JSON, CSV, or PDF, depending on the use case and the preferences of the information producers and consumers. However, XML has some advantages over other formats, such as:
XML is more expressive and flexible than JSON or CSV, as it can define complex data types, schemas, namespaces, and validation rules.
XML is more standardized and interoperable than PDF, as it can be easily parsed, transformed, validated, and queried by various tools and languages.
XML is more compatible with existing CTI standards and tools than other formats, as it is the basis for STIX 1.x, TAXII 1.x, MAEC, CybOX, OVAL, and others.

NEW QUESTION # 248
An organization conducted a web application vulnerability assessment against the corporate website, and the following output was observed:
Which of the following tuning recommendations should the security analyst share?
- A. Block requests without an X-Frame-Options header
- B. Disable the cross-origin resource sharing header
- C. Set an HttpOnlvflaq to force communication by HTTPS
- D. Configure an Access-Control-Allow-Origin header to authorized domains
Answer: A
Explanation:
The output shows that the web application is vulnerable to clickjacking attacks, which allow an attacker to overlay a hidden frame on top of a legitimate page and trick users into clicking on malicious links. Blocking requests without an X-Frame-Options header can prevent this attack by instructing the browser to not display the page within a frame.
NEW QUESTION # 249
A cybersecurity analyst notices unusual network scanning activity coming from a country that the company does not do business with. Which of the following is the best mitigation technique?
- A. Block the IP range of the scans at the network firewall.
- B. Block the specific IP address of the scans at the network firewall.
- C. Geoblock the offending source country.
- D. Perform a historical trend analysis and look for similar scanning activity.
Answer: C
Explanation:
Geoblocking is a security measure that restricts or blocks access to a network based on geographic location by analyzing IP addresses. Since the company does not do business with that country, blocking all traffic from that country reduces unnecessary and potentially malicious traffic, lowering the attack surface and minimizing exposure to threats originating there.
