問題 #128
Refer to the exhibit.
An engineer received a ticket to analyze a recent breach on a company blog. Every time users visit the blog, they are greeted with a message box. The blog allows users to register, log in, create, and provide comments on various topics. Due to the legacy build of the application, it stores user information in the outdated MySQL database. What is the recommended action that an engineer should take?
答案：B
解題說明：
The alert box in the screenshot ( " HACKED BY 1337 " ) is a classic sign of Cross-Site Scripting (XSS). This occurs when unvalidated input is executed as code in a browser.
To prevent this:
The Cisco CyberOps Associate guide recommends strict input validation as the primary defense against XSS and similar web-based injection attacks.
問題 #129
A security team receives a SIEM notification that Cisco Secure Network Analytics detects abnormally high uploads from an internal workstation to external IP addresses over UDP port 53. Investigation confirms that the addresses are known malicious command-and-control servers. Which two actions effectively block these connections and prevent similar incidents? (Choose two.)
答案：C,E
解題說明：
The confirmed malicious external IP addresses should be added to a blocklist, immediately preventing communication with the identified command-and-control infrastructure. Firewall Security Intelligence should also be configured to block C2 traffic using reputation intelligence and maintained custom lists or feeds.
Cisco describes Security Intelligence as an early filtering layer that blocks known malicious IP addresses, URLs, and domains before deeper inspection is required. Deploying anti-malware on the firewall does not directly address the confirmed destination-based connections. Blocking all outbound UDP/53 traffic is overly broad and may disrupt legitimate DNS resolution. Restricting DNS to trusted resolvers can be a useful architectural control, but the keyed response specifically combines targeted blacklisting with threat- intelligence-based C2 filtering. This aligns with CBRFIR Incident Response Techniques objective 3.5:
recommend mitigation for evaluated alerts from firewalls, SIEM, and Cisco Secure Network Analytics. Cisco Secure Firewall Security Intelligence
問題 #130
Refer to the exhibit.
According to the Wireshark output, what are two indicators of compromise for detecting an Emotet malware download? (Choose two.)
答案：A,D
解題說明：
From the Wireshark capture:
* A (iraniansk.com): This domain is not a known legitimate resource and is hosting a suspicious file named "Fy.exe," strongly indicative of a malware distribution domain.
* D (Fy.exe): The Content-Disposition: attachment; filename="Fy.exe" header explicitly signals a binary executable download, a key indicator in Emotet campaigns.
While Content-Type: application/octet-stream (E) is typical of binary data transfers, it is not unique to malware and cannot by itself serve as a strong IoC. The nginx server (B) and cookie/hash string (C) similarly do not uniquely indicate compromise.
問題 #131
Refer to the exhibit.
Which determination should be made by a security analyst?
答案：B
問題 #132
Refer to the exhibit.
A security analyst notices unusual connections while monitoring traffic. What is the attack vector, and which action should be taken to prevent this type of event?
答案：C
解題說明：
The exhibit shows multipleARP reply packetswith the same IP addresses (192.168.51.105and192.
168.51.201) being mapped todifferent MAC addresses, which triggers the message: "duplicate use of [IP] detected". This is a strong indicator of anARP spoofing(or poisoning) attack.
ARP spoofing occurs when a malicious actor sends falsified ARP messages to associate their MAC address with the IP address of another host. This misleads other devices on the network and allows interception or redirection of traffic.
The Cisco CyberOps Associate guide specifically recommendsconfiguring port securityon switches as a method tomitigate ARP spoofing, by limiting the number of MAC addresses allowed per port or statically assigning legitimate MAC addresses to switch ports.
