問題 #99
Refer to the exhibit.

What should an engineer determine from this Wireshark capture of suspicious network traffic?

A. There are signs of SYN flood attack, and the engineer should increase the backlog and recycle the oldest half-open TCP connections.
B. There are signs of a malformed packet attack, and the engineer should limit the packet size and set a threshold of bytes as a countermeasure.
C. There are signs of a DNS attack, and the engineer should hide the BIND version and restrict zone transfers as a countermeasure.
D. There are signs of ARP spoofing, and the engineer should use Static ARP entries and IP address-to- MAC address mappings as a countermeasure.

答案：A

解題說明：
In the provided Wireshark capture, we see multiple TCP SYN packets being sent from different source IP addresses to the same destination IP address (192.168.1.159:80) within a short time window. These SYN packets do not show a corresponding SYN-ACK or ACK response, indicating that these TCP connection requests are not being completed.
This pattern is indicative of a SYN flood attack, a type of Denial of Service (DoS) attack. In this attack, a malicious actor floods the target system with a high volume of TCP SYN requests, leaving the target ' s TCP connection queue (backlog) filled with half-open connections. This can exhaust system resources, causing legitimate connection requests to be denied or delayed.
The countermeasure for this scenario, as highlighted in the CyberOps Technologies (CBRFIR) 300-215 study guide under Network-Based Attacks and TCP SYN Flood Attacks, involves:
Increasing the backlog queue: This allows the server to hold more half-open connections.
Recycling the oldest half-open connections: This ensures that legitimate connections have a chance to be established if the backlog fills up.
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter 5: Identifying Attack Methods, SYN Flood Attack section, page 146-148.

問題 #100
A cybersecurity analyst is analyzing a complex set of threat intelligence data from internal and external sources. Among the data, they discover a series of indicators, including patterns of unusual network traffic, a sudden increase in failed login attempts, and multiple instances of suspicious file access on the company's internal servers. Additionally, an external threat feed highlights that threat actors are actively targeting organizations in the same industry using ransomware. Which action should the analyst recommend?

A. Propose isolation of affected systems and activating the incident response plan because the organization is likely under attack by the new ransomware strain.
B. Advise on monitoring the situation passively because network traffic anomalies are coincidental and unrelated to the ransomware threat.
C. Notify of no requirement for immediate action because the suspicious file access incidents are normal operational activities and do not indicate an ongoing threat.
D. Advocate providing additional training on secure login practices because the increase in failed login attempts is likely a result of employee error.

答案：A

解題說明：
The described scenario includes both internal alerts (unusual network traffic, failed logins, suspicious file access) and external intelligence indicating active ransomware campaigns in the same industry. This constitutes a strong combination of precursors and indicators, as defined in the NIST SP 800-61 incident handling model and reinforced in the Cisco CyberOps Associate curriculum.
According to the Cisco guide:
* "Once an incident has occurred, the IR team needs to contain it quickly before it affects other systems and networks within the organization."
* "The containment phase is crucial in stopping the threat from spreading and compromising more systems".
Given these indicators and the high-value nature of the data involved, it is essential to proactively isolate suspected systems and activate the incident response plan to prevent damage from potential ransomware.

問題 #101
Which issue is associated with gathering evidence from virtualized environments provided by major cloud vendors?

A. simplified chain of custody due to virtualization
B. difficulty ensuring the integrity of data due to multitenancy
C. increased data transparency provided by cloud vendors
D. reduced complexity in isolating and securing evidence

答案：B

問題 #102
A security analyst receives a notification from SIEM that an internal host has active connections to Tor exit nodes. The analyst investigates SIEM events related to the workstation and identifies that the host scans networks for servers with an opened TCP port 1433 An antivirus scan of the workstation does not determine any suspicious activity Which two actions must the analyst take to mitigate this behavior? (Choose two.)

A. Deploy EDR and SOAR for automatic quarantine of actions from suspicious hosts
B. Block Tor nodes via an NGFW and restrict access to SQL only from trusted sources
C. Block any connection to TCP port 1433 from external sources.
D. Configure SIEM alert rules to perform quick response and mitigation
E. Create a Cisco Secure Network Analytics notification rule to further investigate port scanning activity

答案：C,D

問題 #103
During a routine inspection of system logs, a security analyst notices an entry where Microsoft Word initiated a PowerShell command with encoded arguments. Given that the user's role does not involve scripting or advanced document processing, which action should the analyst take to analyze this output for potential indicators of compromise?

A. Validate the frequency of PowerShell usage across all hosts to establish a baseline.
B. Review the encoded PowerShell arguments to decode and determine the intent of the script.
C. Monitor the Microsoft Word startup times to ensure they align with business hours.
D. Confirm that the Microsoft Word license is valid and the application is updated to the latest version.

答案：B

解題說明：
According to theCyberOps Technologies (CBRFIR) 300-215 study guidecurriculum, when analyzing suspicious behavior-especially when scripts or shell commands are executed from applications like Word (which is uncommon)-the encoded PowerShell payload must be decoded to determine if malicious intent is present. Deobfuscation is a critical step in identifying command-and-control behavior, persistence, or malware execution paths.
