Which technology is commonly used to monitor network data and identify security incidents?
A. SOAR (Security Orchestration, Automation, and Response)
B. IDS (Intrusion Detection System)
C. Firewall
D. SIEM (Security Information and Event Management)
正解：D
解説：
SIEM is a technology that focuses on monitoring network data to identify security incidents. It collects and analyzes security event logs from various sources, such as firewalls, intrusion detection systems (IDS), and antivirus software, to identify abnormal behavior or potential security incidents. SIEM solutions provide real-time monitoring, correlation, and alerting capabilities, enabling organizations to effectively detect and respond to security threats.
質問 # 270
Your home network seems to have slowed down considerably. You look at the home router GUI and notice that an unknown host is attached to the network.
What should you do to prevent this specific host from attaching to the network again?
A. Change the network SSID.
B. Block the host IP address.
C. Create an IP access control list.
D. Implement MAC address filtering.
正解：D
解説：
The CCST Cybersecurity course explains that MAC address filtering is a network access control method that allows only approved device hardware addresses to connect. While not foolproof against spoofing, it can block a specific device from reconnecting to a small home network.
"MAC address filtering restricts network access to devices whose unique hardware addresses are explicitly allowed. This can be used to block known unauthorized devices from reconnecting." (CCST Cybersecurity, Basic Network Security Concepts, Wireless Security Controls section, Cisco Networking Academy) A is incorrect: IP ACLs are better for controlling traffic types, not blocking specific devices at the router level.
B is correct: It prevents the device's hardware address from reconnecting.
C is temporary since the host can get a new IP via DHCP.
D may hide the network but will not stop a determined attacker who can still detect it.
質問 # 271
Which of the following is a key role of a Cisco Certified Support Technician (CCST) in cybersecurity?
A. Managing network infrastructure
B. Designing user interfaces
C. Conducting penetration testing
D. Developing software applications
正解：A
解説：
A CCST in cybersecurity is primarily responsible for managing and maintaining network infrastructure to ensure the security of data and systems. They handle tasks such as monitoring network traffic, configuring firewalls, implementing security protocols, and troubleshooting network vulnerabilities.
質問 # 272
What is a common outcome of a vulnerability assessment?
A. A list of all vulnerabilities found in the system.
B. A detailed report on the system's security posture.
C. Confirmation that the system is completely secure.
D. Remediation steps to fix identified vulnerabilities.
正解：B
解説：
A common outcome of a vulnerability assessment is a detailed report that provides an overview of the system's security posture. This report may include information about vulnerabilities, their severity, recommendations for remediation, and overall risk assessment.
質問 # 273
Which of the following threat intelligence techniques involves monitoring network traffic and analyzing abnormal patterns or behaviors?
A. Indicators of Compromise (IoCs)
B. Anomaly-based Detection
C. Signature-based Detection
D. Reputation-based Detection
正解：B
解説：
Anomaly-based detection involves monitoring network traffic and comparing it against baseline or normal behavior. It looks for any abnormal patterns or behaviors that could indicate potential threats.
