A database administrator is updating the company's SQL database, which stores credit card information for pending purchases. Which of the following is the best method to secure the data against a potential breach?
Answer(s): C
Tokenization replaces sensitive data, like credit card information, with a unique identifier (token) that has no exploitable value outside of a specific context. This approach is widely used to secure payment card information and reduces the risk of exposure in case of a breach, as the actual credit card data is not stored in the database.
Which of the following is a benefit of vendor diversity?
Answer(s): B
Vendor diversity can help mitigate the impact of zero-day vulnerabilities. By using multiple vendors for similar services or components, organizations reduce the likelihood that a single vulnerability affecting one vendor's products will compromise the entire system. This diversity creates resilience against attacks exploiting unknown vulnerabilities in any single vendor's software.
An employee used a company's billing system to issue fraudulent checks. The administrator is looking for evidence of other occurrences of this activity. Which of the following should the administrator examine?
Answer(s): A
Application logs will contain records of activities within the billing system, including transactions, actions taken by users, and any anomalies. This is the most direct source of evidence for tracing fraudulent activity within the specific application, such as issuing unauthorized checks.
An organization is looking to optimize its environment and reduce the number of patches necessary for operating systems. Which of the following will best help to achieve this objective?
Answer(s): D
Containers package applications with only the necessary components and dependencies, which reduces the footprint of the operating system components in each instance. This approach minimizes the number of OS patches required, as each container runs only essential services instead of a full OS environment, making it easier to isolate and update application dependencies without affecting the host or requiring frequent OS-level patches.
Which of the following tasks is typically included in the BIA process?
In a BIA, estimating the recovery time of systems, also known as the Recovery Time Objective (RTO), is crucial. The BIA process focuses on identifying critical systems, understanding the impact of their unavailability, and determining acceptable downtime. This helps in planning for recovery times, resource allocation, and continuity strategies.
Which of the following is a risk of conducting a vulnerability assessment?
During a vulnerability assessment, scanning or testing can sometimes interfere with normal system operations, potentially leading to slowdowns, unresponsiveness, or even outages. This can disrupt business operations, especially if the assessment is run on production systems without adequate precautions or scheduling during low-impact times.
Which of the following techniques would attract the attention of a malicious attacker in an insider threat scenario?
A file with a name like "salaries" suggests sensitive information, which would likely draw the attention of an insider threat looking for valuable or confidential data. This technique is often used as part of a honeypot strategy to monitor and detect suspicious activity by insiders attempting unauthorized access.
An organization maintains intellectual property that it wants to protect. Which of the following concepts would be most beneficial to add to the company's security awareness training program?
Insider threats pose a significant risk to intellectual property, as insiders often have access to sensitive information and may attempt to misuse it. Training employees to recognize signs of insider threats, along with implementing monitoring and reporting protocols, helps protect intellectual property from theft or unauthorized disclosure by employees or other trusted individuals within the organization.

Question 142:Correct answer: A — Determining the root cause of the incident The post-incident review—also called a lessons-learned review—analyzes what happened and why. Determining the root cause helps the organization fix the underlying weakness and prevent recurrence. Why the other options are less suitable:
