Cisco 300-215 Exam Dumps

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.

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.

Cisco Secure Endpoint (formerly AMP for Endpoints) offers features like:

File trajectory: to track file behavior and spread across endpoints.

Orbital Advanced Search: for querying endpoint data to detect threats in real time.

Comprehensive and Detailed

Endpoint Detection and Response (EDR) tools provide behavioral analytics and continuous monitoring to detect malware such as backdoors, which is especially critical on endpoints like macOS devices. These tools are essential to detect post-compromise activities and contain threats before they spread.

Secure Email Gateway (e.g., Cisco ESA) plays a key role in blocking phishing emails---the initial vector in this attack. It uses filters and reputation analysis to prevent malicious links or attachments from reaching end users.

Incorrect Options:

C . DLP focuses on preventing data exfiltration, not phishing prevention or backdoor detection.

D . IPS is effective for known signature-based threats but less effective against phishing links and endpoint-level backdoors.

E . WAF protects web servers, not end-user devices from phishing or backdoor infections.

Therefore, the correct answers are: A and B.

The alert shown is based on a Snort rule for a Unicode directory traversal attack against IIS web servers (Microsoft platform). The key detail here is the payload content '../..%c0%af../' which is a classic IIS-specific exploit related to CVE-2000-0884.

Since the company only uses Unix systems, they are not vulnerable to this IIS-specific attack. Therefore, these alerts are triggered by irrelevant traffic or misapplied signatures, resulting in False Positives.

As defined in the Cisco CyberOps guide:

''False Positive: an alert is generated for traffic that is not actually malicious or relevant to the protected environment''.

The correct next step in analyzing the malicious nature of the email is to evaluate the artifacts in Cisco Secure Malware Analytics (formerly Threat Grid). This tool provides a comprehensive sandbox environment where behavioral indicators like file execution, registry access, and domain connections are logged and scored.

The exhibit shows:

Remote PowerShell execution

Executable download from a flagged domain

SHA256 hash linked to malware

All these artifacts, as labeled in the Secure Malware Analytics output, are key indicators of compromise, and analyzing them further can confirm whether the email was part of a malicious campaign.

Thus, the best action is: A . Evaluate the artifacts in Cisco Secure Malware Analytics.
