NEW QUESTION # 131
Which of the following is an advantage of SOAR over SIEM?
- A. SOAR reduces the amount of human intervention required.
- B. SOAR can aggregate data from many sources.
- C. SOAR is much less expensive.
- D. SOAR uses more robust encryption protocols.
Answer: B
Explanation:
Explanation
SOAR systems and services tend to add a layer of workflow management. That means that SOAR deployments may actually ingest SIEM alerts and other data and then apply workflows and automation to them. SIEM and SOAR tools can be difficult to distinguish from each other, with one current difference being the broader range of tools that SOAR services integrate with. The same vendors who provide SIEM capabilities also provide SOAR systems in many cases with Splunk, Rapid7, and IBM (QRadar) all included.
There are differences, however, as ITSM tools like ServiceNow play in the space as well. As an analyst, you need to know that SOAR services and tools exist and can be leveraged to cover additional elements beyond what traditional SIEM systems have historically handled.

Industry partners from critical infrastructure organizations were victims of attacks on their SCADA devices. The attacker was able to gain access to the SCADA by logging in to an account with weak credentials. Which of the following identity and access management solutions would help to mitigate this risk?
- A. Endpoint detection and response
- B. Manual access reviews
- C. Role-based access control
- D. Multifactor authentication
Answer: D
NEW QUESTION # 133
Which of the following solutions is the BEST method to prevent unauthorized use of an API?
- A. Authentication
- B. HTTPS
- C. Geofencing
- D. Rate liming
Answer: A
Explanation:
Authentication is a method of verifying a user's identity by requiring some piece 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). Authentication is the best method to prevent unauthorized use of an API, because it ensures that only legitimate users can access or use the API functions or data. HTTPS, geofencing, or rate limiting are other methods that can enhance the security or performance of an API, but they do not prevent unauthorized use of an API.

NEW QUESTION # 136
An organization is experiencing security incidents in which a systems administrator is creating unauthorized user accounts A security analyst has created a script to snapshot the system configuration each day. Following iss one of the scripts:
This script has been running successfully every day. Which of the following commands would provide the analyst with additional useful information relevant to the above script?
A)
B)
C)
- A. Option C
- B. Option D
- C. Option B
- D. Option A
Answer: B
Explanation:
Option D would provide the analyst with additional useful information relevant to the above script. Option D is a command that compares two files and shows the differences between them. In this case, the command compares the current snapshot of the system configuration (sysconfig.txt) with the previous snapshot (sysconfig.txt.old). This can help the analyst to identify any changes or anomalies in the system configuration that may indicate unauthorized or malicious activity. Option A is a command that copies a file from one location to another. In this case, the command copies the current snapshot of the system configuration (sysconfig.txt) to a backup location (/backup/sysconfig.txt). This can help the analyst to preserve evidence or restore the system configuration if needed, but it does not provide any additional information relevant to the above script. Option B is a command that prints a file to standard output. In this case, the command prints the current snapshot of the system configuration (sysconfig.txt) to the screen. This can help the analyst to review or analyze the system configuration, but it does not provide any additional information relevant to the above script. Option C is a command that moves a file from one location to another. In this case, the command moves the current snapshot of the system configuration (sysconfig.txt) to another location (/old/sysconfig.txt). This can help the analyst to organize or archive the system configuration files, but it does not provide any additional information relevant to the above script.

Which of the following types of controls defines placing an ACL on a file folder?
- A. Operational control
- B. Technical control
- C. Confidentiality control
- D. Managerial control
Answer: B
Explanation:
"Technical controls enforce confidentiality, integrity, and availability in the digital space. Examples of technical security controls include firewall rules, access control lists, intrusion prevention systems, and encryption." A technical control is a type of control that uses technology or software to protect data and systems from unauthorized access or misuse3. A technical control can include encryption, authentication, firewalls, antivirus software, and other mechanisms that rely on hardware or software. Placing an ACL (access control list) on a file folder is an example of a technical control. An ACL is a list of permissions that specifies who can access or modify a file or folder4. An ACL can help to enforce confidentiality, integrity, and availability of data by restricting access to authorized users only.
NEW QUESTION # 147
A security analyst notices the following proxy log entries:
Which of the following is the user attempting to do based on the log entries?
- A. Exfiltrate data.
- B. Scan the network.
- C. Relay email.
- D. Use a DoS attack on external hosts.
Answer: B
Explanation:
Scanning the network is what the user is attempting to do based on the log entries. The log entries show that the user is sending ping requests to various IP addresses on different ports using a proxy server. Ping requests are a common network diagnostic tool that can be used to test network connectivity and latency by sending packets of data and measuring their response time. However, ping requests can also be used by attackers to scan the network and discover active hosts, open ports, or potential vulnerabilities .
