Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps 認定 300-215 試験問題 (Q85-Q90):

質問 # 85
The Linux system administrator of a company suspects that physical unauthorized access was granted to a local Linux terminal. The administrator wants to examine the suspected machine for potential unauthorized use and to get information about even/ account in this terminal including when the password last changed The administrator logs in as a root user Which file should be examined to get the information?

正解：A

解説：
* /etc/shadow: This file stores encrypted passwords and password aging information, including the date of the last password change (stored as the number of days since January 1, 1970). It is only readable by the root user, making it the primary source for forensic auditing of local password changes.


質問 # 86
Refer to the exhibit.

According to the SNORT alert, what is the attacker performing?

正解：A

解説：
The alert clearly identifies ET SCAN DirBuster Web App Scan in Progress, referencingSID 2008186, which is a Snort signature that specifically detectsDirBusteractivity. DirBuster is a well-known tool used for brute- forcing hidden directories and files on web servers.
The Cisco CyberOps Associate guide and OWASP both identifydirectory brute-forcingas a reconnaissance technique to find unprotected or misconfigured endpoints on web applications, typically prior to launching deeper attacks.
Therefore, the correct interpretation of the alert is:
C). brute-force attack against directories and files on the target webserver.


質問 # 87
Refer to the exhibit.

What should be determined from this Apache log?

正解：C

解説：
The error logs indicate multiplePKCS12andASN.1 decodingerrors, such as:
* PKCS12 routines:PKCS12_parse:mac verify failure
* rsa routines:old_rsa_priv_decode:RSA lib
* PKCS12 routines:PKCS12_key_gen_uni:malloc
These specific errors most commonly occur when:
* Theprivate key does not correspondto the certificate being used.
* There is amismatchbetween the public and private key pair required for SSL handshakes.
This is a well-documented condition in Apache SSL configuration issues and explicitly covered under TLS
/SSL troubleshooting sections in cybersecurity operations contexts. The Cisco CyberOps guide also notes that SSL errors with key verification usually result from "improper key/certificate pairing" rather than file corruption or missing modules.
Thus, the correct answer is:
B). The private key does not match with the SSL certificate.


質問 # 88

正解：A

解説：
This Python script uses a combination of libraries (urllib,zlib,base64, andssl) to:
* Disable SSL certificate verification (ssl.CERT_NONEandcheck_hostname=False).
* Construct a custom HTTPS opener with the specified SSL context.
* Add a forgedUser-Agentheader to mimic Internet Explorer 11.
* Connect to the URLhttps://23.1.4.14:8443.
* Download and execute base64-encoded and zlib-compressed content from that URL using:
exec(zlib.decompress(base64.b64decode(...).read()))
This shows a classic example of:
* Downloading payloads from a remote server (23.1.4.14:8443).
* Avoiding detection by disabling SSL verification.
* Executing the payload dynamically withexec()after decoding and decompressing.
The main goal is clearly to initiate a connection to a remote command-and-control (C2) server on port 8443 and download/execute additional code.
Hence, the correct answer is: A. Initiate a connection to 23.1.4.14 over port 8443.


質問 # 89
Which code snippet reflects Python 2.7 syntax-based reverse-shell code?

正解：B

解説：
Option C uses Python modules and syntax valid in Python 2.7: it imports socket, subprocess, and os; creates an IPv4 TCP stream socket; connects to a remote IP address and port; duplicates the socket descriptor onto standard input, output, and error; and launches an interactive /bin/sh. That redirection gives the remote listener command execution, which is the defining behavior of a reverse shell. The other snippets are recognizable as Ruby, Perl, and PHP implementations respectively. CBRFIR Forensics Techniques objective 2.4 requires determining the type of code from a provided snippet, while process and network analysis should verify any inferred behavior. Python's official documentation confirms that AF_INET uses a host-and-port tuple and that SOCK_STREAM creates a stream socket. Analysts should treat the code as evidence and never execute it outside an isolated laboratory. Python 2.7 socket documentation
