300-215 Exam Dumps : Conducting Forensic Analysis and Incident Response Using Cisco CyberOps Technologies (CBRFIR v1.2)

Once an incident has occurred, the appropriate course of action is to engage the organization's Incident Response (IR) plan. This is a structured approach to contain, analyze, and eradicate threats before they spread across the network.

The Cisco CyberOps Associate study guide emphasizes:

“Incident response and handling are essential within an organization… The main objective of implementing an incident handling process is to reduce the impact of a cyber-attack, ensure the damages caused are assessed, and implement recovery procedures”.

In particular, the containment phase of IR is focused on isolating the threat and preventing lateral movement or further compromise.

Options such as "root cause" or "attack surface" are relevant at later stages of analysis and mitigation, not immediate containment. Therefore, the correct answer is C.

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.

YARA rules are primarily used for malware classification and detection based on binary pattern matching within files. They describe sequences of bytes, strings, and other file characteristics found in malicious binaries.

The Cisco CyberOps Associate guide explains: "YARA rules operate by inspecting binary data using conditions and string matches to identify specific patterns that indicate known malware samples.".
