Drag and drop the capabilities on the left onto the Cisco security solutions on the right.

答案：

解題說明：

問題 #38
Refer to the exhibit.

An engineer is analyzing a .LNK (shortcut) file recently received as an email attachment and blocked by email security as suspicious. What is the next step an engineer should take?

A. Upload the file to a virus checking engine to compare with well-known viruses as the file is a virus disguised as a legitimate extension.
B. Delete the suspicious email with the attachment as the file is a shortcut extension and does not represent any threat.
C. Open the file in a sandbox environment for further behavioral analysis as the file contains a malicious script that runs on execution.
D. Quarantine the file within the endpoint antivirus solution as the file is a ransomware which will encrypt the documents of a victim.

答案：C

解題說明：
The metadata in the exhibit reveals a strong indicator that this .LNK file (shortcut) is malicious:
The shortcut file is named " ds7002.pdf " but actually points to the execution of PowerShell:# Full path: C:
\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Arguments include:# -noni -ep bypass $z = ' ... ' ; indicating an attempt to run a PowerShell script with execution policy bypassed (a known tactic for fileless malware delivery).
The file is masked as a PDF (common social engineering technique), and PowerShell execution via .LNK is a signature technique used by many malware families to initiate second-stage payloads or scripts.
Given this, the correct and safest course of action is to:
# Open the .LNK file in a sandbox environment (D).
This enables safe behavioral analysis to observe what actions it attempts upon execution without endangering live systems.
Other options are inappropriate:
A (ignoring the threat due to extension) is dangerous - .LNKs can trigger code.
B (upload to virus engine) is only helpful for known malware and lacks behavioral context.
C (quarantine) is preventive but not investigative - sandboxing provides visibility.
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Threat Hunting and Malware Analysis," section covering shortcut (.LNK) based attacks, PowerShell-based threats, and sandbox behavioral analysis strategies.

問題 #40
A security team detected an above-average amount of inbound tcp/135 connection attempts from unidentified senders. The security team is responding based on their incident response playbook. Which two elements are part of the eradication phase for this incident? (Choose two.)

A. centralized user management
B. intrusion prevention system
C. enterprise block listing solution
D. data and workload isolation
E. anti-malware software

答案：A,B

解題說明：
The eradication phase in incident response involves eliminating the root cause of the incident and strengthening defenses to prevent reoccurrence. In this case:
Intrusion Prevention System (D): Adding new rules to the IPS to detect and block malicious activity on TCP
/135 is a direct eradication step to remove the threat's entry point and prevent future attacks.
Centralized User Management (C): Hardening user accounts, removing unnecessary permissions, and applying tighter authentication/authorization measures helps eliminate the possibility that threat actors could exploit weak or mismanaged accounts to continue accessing the system.
Although anti-malware software (A) and enterprise block listing (E) are valuable, the most direct eradication steps here specifically involve managing network access (via IPS) and strengthening user controls (via centralized user management), especially when TCP/135 (MSRPC endpoint mapper) can be used to enumerate services and potentially access vulnerable endpoints remotely.
This aligns with best practices outlined in incident response frameworks (such as the NIST SP 800-61 and referenced resources), which emphasize closing the exploited entry points (in this case, TCP/135) and removing any lingering access points through user management and network control enhancements.
