As part of the lessons-learned phase, the SOC is tasked with building methods to detect if a previous incident is happening again. Which of the following would allow the security analyst to alert the SOC if an event is reoccurring?
- A. Implementing rules in the NGFW
- B. Updating the DLP hash database
- C. Publishing a new CRL with revoked certificates

- B. Race condition
- C. SQL injection
- D. VM escape
正解：A
解説：
A buffer overflow is a type of vulnerability that occurs when an attacker sends more data than a buffer can hold, causing the excess data to overwrite adjacent memory locations such as registers. It can allow an attacker to overwrite a register with a malicious address that changes the execution path and executes arbitrary code on the target system

質問 # 464
A company is developing a business continuity strategy and needs to determine how many staff members would be required to sustain the business in the case of a disruption.
Which of the following best describes this step?
- A. Capacity planning
- B. Geographic dispersion
- C. Redundancy
- D. Tabletop exercise
正解：A
解説：
Capacity planning is the process of determining the resources needed to meet the demand for a service or product. It involves estimating the number of staff members required to sustain the business in the case of a disruption, as well as other factors such as equipment, space, and budget12.
Redundancy, geographic dispersion, and tabletop exercise are not directly related to determining the staff members needed for business continuity. Redundancy is the duplication of critical components or functions to increase reliability and availability2. Geographic dispersion is the distribution of resources across different locations to reduce the impact of a localized disaster2. Tabletop exercise is a simulation of a potential scenario that tests the effectiveness of a business continuity plan
質問 # 465
An employee in the accounting department receives an email containing a demand for payment for services performed by a vendor. However, the vendor is not in the vendor management database. Which of the following is this scenario an example of?
- A. Invoice scam
- B. Ransomware
- C. Pretexting
- D. Impersonation
正解：A
質問 # 466
A security analyst was called to Investigate a file received directly from a hardware manufacturer.
The analyst is trying to determine whether the file was modified in transit before installation on the user's computer. Which of the following can be used to safely assess the file?
- A. Verify the URL download location
- B. Match the file names
- C. Verify the code-signing certificate
- D. Check the hash of the installation file
正解：D
解説：
The hardware manufacturer will post the hash of the file publicly, and anyone who receives a copy of that file will be able to run a checksum on the file themselves, and compare them to the official manufacturer-provided checksum. Hashing is almost always the correct answer in these type of questions. You'll see a lot of Github repositories using hashed checksums as well for verification, and I recently just installed Java onto my new computer. Java provided me with a hashed checksum for the setup executable.
質問 # 467
A security incident has been resolved Which of the following BEST describes the importance of the final phase of the incident response plan?
- A. It examines and documents how well the team responded discovers what caused the incident, and determines how the incident can be avoided in the future

- C. It returns the affected systems back into production once systems have been fully patched, data restored and vulnerabilities addressed
- D. It identifies the incident and the scope of the breach how it affects the production environment, and the ingress point
正解：A

- A. Regional regulations
- B. CIS benchmarks
- C. ISO 27001 standards
- D. GDPR guidance
正解：B
解説：
CIS benchmarks are best practices and standards for securing various operating systems, applications, cloud environments, etc. They are developed by a community of experts and updated regularly to reflect the latest threats and vulnerabilities. They can be used to update and reconfigure the OS-level security configurations to ensure compliance and reduce risks.
質問 # 470
A systems analyst determines the source of a high number of connections to a web server that were initiated by ten different IP addresses that belong to a network block in a specific country. Which of the following techniques will the systems analyst MOST likely implement to address this issue?
- A. DLP
- B. Content filter
- C. Firewall rules
- D. SIEM
正解：C
解説：
Explanation
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. The systems analyst can use firewall rules to block connections from the ten IP addresses in question, or from the entire network block in the specific country. This would be a quick and effective way to address the issue of high connections to the web server initiated by these IP addresses.

質問 # 471
A security analyst discovers that a large number of employee credentials had been stolen and were being sold on the dark web. The analyst investigates and discovers that some hourly employee credentials were compromised, but salaried employee credentials were not affected.
Most employees clocked in and out while they were inside the building using one of the kiosks connected to the network. However, some clocked out and recorded their time after leaving to go home. Only those who clocked in and out while inside the building had credentials stolen. Each of the kiosks are on different floors, and there are multiple routers, since the business segments environments for certain business functions.
Hourly employees are required to use a website called acmetimekeeping.com to clock in and out. This website is accessible from the internet. Which of the following is the most likely reason for this compromise?
- A. The internal DNS servers were poisoned and were redirecting acmetimekeeping.com to a malicious domain that intercepted the credentials and then passed them through to the real site.
- B. ARP poisoning affected the machines in the building and caused the kiosks to send a copy of all the submitted credentials to a malicious machine.
- C. A malicious actor compromised the time-keeping website with malicious code using an unpatched vulnerability on the site, stealing the credentials.
- D. A brute-force attack was used against the time-keeping website to scan for common passwords.
正解：B
解説：
ARP poisoning is a technique by which an attacker sends spoofed ARP messages to alter routing on a local area network. It can be used to intercept, modify, or stop data frames, or launch other attacks3 In this scenario, the attacker likely used ARP poisoning to associate their MAC address with the IP address of the time-keeping website, causing the kiosks to send a copy of all the submitted credentials to the attacker's machine. This explains why only the credentials of the employees who clocked in and out while inside the building were stolen, and why the compromise was not detected by the DNS servers or the website itself4
