質問 # 153
Refer to the exhibit.

質問 # 155
Refer to the exhibit.

A web hosting company analyst is analyzing the latest traffic because there was a 20% spike in server CPU usage recently. After correlating the logs, the problem seems to be related to the bad actor activities. Which attack vector is used and what mitigation can the analyst suggest?

A. Distributed denial of service; use rate limiting and DDoS protection services.
B. SQL Injection; implement input validation and use parameterized queries.
C. Brute-force attack; implement account lockout policies and roll out MFA.
D. Phishing attack; conduct regular user training and use email filtering solutions.

正解：C

解説：
Comprehensive and Detailed Explanation:
The log entries show repeated SSH login attempts for various invalid usernames (e.g., admin, phoenix, rainbow, test, user, etc.) from different source ports. These are clear signs of a brute-force attack-an automated process trying multiple usernames and passwords in hopes of gaining access.
Mitigating such attacks includes:
* Implementing account lockout policies (e.g., locking an account after several failed login attempts).
* Enabling Multi-Factor Authentication (MFA) to ensure that password guessing alone is insufficient for account access.
Therefore, the correct answer is:
D). Brute-force attack; implement account lockout policies and roll out MFA.

質問 # 156
An insider scattered multiple USB flash drives with zero-day malware in a company HQ building. Many employees connected the USB flash drives to their workstations. An attacker was able to get access to endpoints from outside, steal user credentials, and exfiltrate confidential information from internal web resources. Which two steps prevent these types of security incidents in the future? (Choose two.)

A. Provide security awareness training and block usage of external drives.
B. Deploy MFA authentication to prevent unauthorized access to critical assets.
C. Encrypt traffic from employee workstations to internal web services.
D. Automate security alerts on connected USB flash drives to workstations.
E. Deploy antivirus software on employee workstations to detect malicious software.

正解：A、B

解説：
The scenario describes an attack vector where insiders or malicious actors useremovable media (USB drives) to introduce malware, which then connects to external sources to exfiltrate data and compromise systems.
* Option B addresses the human factor and technological prevention. The guide stresses the need for training to ensure users are aware of social engineering and removable media risks. Blocking the use of USB drives at a system level further minimizes attack vectors.
* Option E, usingMulti-Factor Authentication (MFA), provides an additional layer of defense. Even if credentials are stolen, MFA can prevent the attacker from accessing sensitive internal resources without the second authentication factor.
These controls align with defense-in-depth strategies recommended in the Cisco CyberOps Associate curriculum to combat insider threats and external unauthorized access.

質問 # 157
Refer to the exhibit.

A cybersecurity analyst is presented with the snippet of code used by the threat actor and left behind during the latest incident and is asked to determine its type based on its structure and functionality. What is the type of code being examined?

A. network monitoring script for capturing incoming traffic
B. simple client-side script for downloading other elements
C. basic web crawler for indexing website content
D. socket programming listener for TCP/IP communication

正解：D

解説：
The Python code snippet:
Uses socket.socket(AF_INET, SOCK_STREAM), which indicates TCP communication Connects to a remote server (192.168.1.10 on port 80) Sends a manual HTTP GET request Receives the response using s.recv() This is a classic example of TCP/IP socket programming, specifically creating a simple TCP client to communicate with a web server. It does not monitor traffic or crawl websites - it sends a crafted request and prints the response.
Thus, this code best fits:
D). socket programming listener for TCP/IP communication.
