Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps Sample Questions (Q51-Q56):

NEW QUESTION # 51
Refer to the exhibit.

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

Answer: D

Explanation:
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.


NEW QUESTION # 52
Refer to the exhibit.

Which type of code created the snippet?

Answer: C

Explanation:
The syntax in the code snippet includes:
On Error Resume Next - a classic VBScript error-handling directive.
function ... end function structure.
Use of Mid(), Chr(), and Asc() functions - all commonly used in VBScript for string manipulation.
CInt() for conversion - typical in VBScript.
These characteristics align exactly with VBScript, which is frequently used in malicious macros and obfuscated payloads for malware distribution, as covered in the Cisco CyberOps Associate curriculum when analyzing scripts and encoded threats.


NEW QUESTION # 53
Which scripts will search a log file for the IP address of 192.168.100.100 and create an output file named parsed_host.log while printing results to the console?

Answer: D

Explanation:
To determine the correct script, we evaluate the following requirements:
* The script must search for the IP address 192.168.100.100.
* The output should be written to a file named parsed_host.log.
* The matching lines should be printed to the console.
Analysis of the options:
* Option A: Correct IP regex used and correct output filename, but reads from parsed_host.log instead of a source log file like test_log.log (not ideal for initial parsing).
* Option C: The IP address used is 192.168.100.101 instead of 192.168.100.100 - incorrect.
* Option D: Same IP address and logic as Option B, but uses print statement without parentheses, which is not valid in Python 3 unless using Python 2 - not ideal.
# Option B:
* Uses correct IP: "192.168.100.100"
* Reads from test_log.log (presumably the source log file).
* Writes to output/parsed_host.log.
* Prints each matching line and writes to output file - satisfying all conditions.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Investigating Host-Based Evidence and Logs" emphasizes scripting log parsing tasks using Python's regex and file I/O for filtering artifacts like IP addresses. Scripts should ensure proper source log input, pattern matching, result redirection, and optional output logging for forensics analysis.

Answer:

Explanation:


NEW QUESTION # 55
Refer to the exhibit.

After a cyber attack, an engineer is analyzing an alert that was missed on the intrusion detection system. The attack exploited a vulnerability in a business-critical, web-based application and violated its availability.
Which two mitigation techniques should the engineer recommend? (Choose two.)

Answer: A,B

Explanation:
The alert indicates a WebDAV Stack Buffer Overflow, which is a memory corruption attack targeting the stack, a common vector for remote code execution or denial-of-service (DoS).
To mitigate such exploits, two effective system-hardening techniques are:
C). Address Space Layout Randomization (ASLR):Randomizes memory addresses used by system and application processes, making it difficult for attackers to predict where their malicious code will be executed.
E). Data Execution Prevention (DEP):Prevents execution of code from non-executable memory regions such as the stack, thus stopping buffer overflow attacks from successfully executing payloads.
Both are well-established protections against stack-based buffer overflow attacks and are strongly recommended in the Cisco CyberOps Associate guide and general security best practices.
