The SecOps Group Certified Network Security Practitioner Sample Questions (Q59-Q64):

NEW QUESTION # 59
WannaCry, an attack, spread throughout the world in May 2017 using machines running on outdated Microsoft operating systems. What is WannaCry?

A. Malware
B. Ransomware

Answer: B

Explanation:
WannaCry is a ransomware attack that erupted in May 2017, infecting over 200,000 systems across 150 countries. It exploited the EternalBlue vulnerability (MS17-010) in Microsoft Windows SMBv1, targeting unpatched systems (e.g., Windows XP, Server 2003). Developed by the NSA and leaked by the Shadow Brokers, EternalBlue allowed remote code execution.
Ransomware Mechanics:
Encryption: WannaCry used RSA-2048 and AES-128 to encrypt files, appending extensions like .wcry.
Ransom Demand: Displayed a message demanding $300-$600 in Bitcoin, leveraging a hardcoded wallet.
Worm Propagation: Self-replicated via SMB, scanning internal and external networks, unlike typical ransomware requiring user interaction (e.g., phishing).
Malware Context: While WannaCry is malware (malicious software), "ransomware" is the precise subcategory, distinguishing it from viruses, trojans, or spyware. Malware is a broad term encompassing any harmful code; ransomware specifically encrypts data for extortion. CNSP likely classifies WannaCry as ransomware to focus on its payload and mitigation (e.g., patching, backups).
Why other options are incorrect:
B . Malware: Correct but overly generic. WannaCry's defining trait is ransomware behavior, not just maliciousness. Specificity matters in security taxonomy for threat response (e.g., NIST IR 8019).
Real-World Context: WannaCry crippled NHS hospitals, highlighting patch management's criticality. A kill switch (a domain sinkhole) halted it, but variants persist.

NEW QUESTION # 60
In the context of a Unix-based system, where does a daemon process execute in the memory?

A. User space
B. Kernel space

Answer: A

Explanation:
In Unix-based systems, memory is divided into two primary regions: kernel space and user space, each serving distinct purposes for process execution and system stability.
Why B is correct: Daemon processes are background services (e.g., sshd, cron) that run with elevated privileges but operate in user space. User space is the memory area allocated for user applications and processes, isolated from kernel space to prevent direct hardware access or system crashes. CNSP highlights that daemons run in user space to maintain system integrity, interacting with the kernel via system calls.
Why other option is incorrect:
A . Kernel space: Kernel space is reserved for the operating system kernel and device drivers, which have unrestricted access to hardware. Running daemons in kernel space would pose significant security and stability risks, and it is not the standard practice in Unix systems.

NEW QUESTION # 61
According to the screenshot below, which of the following statements are correct?

A. The application is running on port 443 and the HTTPS protocol.
B. The application is running on port 80 and the HTTP protocol.
C. The credentials have been submitted over the HTTP protocol.
D. The credentials have been submitted over the HTTPS protocol.

Answer: A

Explanation:
The screenshot is from Wireshark, a network protocol analyzer, displaying captured network traffic. The relevant columns include the source and destination IP addresses, ports, protocol, and additional information about the packets. Let's break down the details:
Destination Port Analysis: The screenshot shows multiple packets with a destination port of 443 (e.g., in the "Destination" column, entries like "172.72.61.9:443"). Port 443 is the default port for HTTPS (HTTP Secure), which is HTTP traffic encrypted using SSL/TLS. This indicates that the application is communicating over HTTPS.
Protocol Analysis: The "Protocol" column lists "TLSv1.2" for most packets (e.g., frame numbers 2000084, 2000086). TLS (Transport Layer Security) is the cryptographic protocol used by HTTPS to secure HTTP communications. This confirms that the traffic is HTTPS, not plain HTTP.
Packet Details: The "Info" column provides additional context, such as "Application Data" for TLS packets, indicating encrypted application-layer data (typical of HTTPS). There are also HTTP packets (e.g., frame 2000088), but these are likely part of the HTTPS session (e.g., HTTP/2 over TLS, as noted by "HTTP2").
Now, let's evaluate the options:
Option A: "The application is running on port 443 and the HTTPS protocol." This is correct. The destination port 443 and the use of TLSv1.2 confirm that the application is using HTTPS. HTTPS is the standard protocol for secure web communication, and port 443 is its designated port. CNSP documentation emphasizes that HTTPS traffic on port 443 indicates a secure application-layer protocol, often used for web applications handling sensitive data.
Option B: "The credentials have been submitted over the HTTP protocol." This is incorrect. HTTP typically uses port 80, but the screenshot shows traffic on port 443 with TLS, indicating HTTPS. Credentials submitted over this connection would be encrypted via HTTPS, not sent in plaintext over HTTP. CNSP highlights the security risks of HTTP for credential submission due to lack of encryption, which isn't the case here.
Option C: "The credentials have been submitted over the HTTPS protocol." While this statement could be true (since HTTPS is in use, any credentials would likely be submitted securely), the question asks for the "correct" statement based on the screenshot. The screenshot doesn't explicitly show credential submission (e.g., a POST request with form data); it only shows the protocol and port. Option A is more directly supported by the screenshot as it focuses on the application's protocol and port, not the specific action of credential submission. CNSP notes that HTTPS ensures confidentiality, but this option requires more specific evidence of credentials.
Option D: "The application is running on port 80 and the HTTP protocol." This is incorrect. Port 80 is the default for HTTP, but the screenshot clearly shows port 443 and TLS, indicating HTTPS. CNSP documentation contrasts HTTP (port 80, unencrypted) with HTTPS (port 443, encrypted), making this option invalid.
Conclusion: Option A is the most accurate and comprehensive statement directly supported by the screenshot, confirming the application's use of port 443 and HTTPS. While Option C might be true in a broader context, it's less definitive without explicit evidence of credential submission in the captured packets.

NEW QUESTION # 62
Which command will perform a DNS zone transfer of the domain "victim.com" from the nameserver at 10.0.0.1?

A. dig @10.0.0.1 victim.com axfr
B. dig @10.0.0.1 victim.com axrfr
C. dig @10.0.0.1 victim.com arfxr
D. dig @10.0.0.1 victim.com afxr

Answer: A

Explanation:
A DNS zone transfer replicates an entire DNS zone (a collection of DNS records for a domain) from a primary nameserver to a secondary one, typically for redundancy or load balancing. The AXFR (Authoritative Full Zone Transfer) query type, defined in RFC 1035, facilitates this process. The dig (Domain Information Groper) tool, a staple in Linux/Unix environments, is used to query DNS servers. The correct syntax is:
dig @<nameserver> <domain> axfr
Here, dig @10.0.0.1 victim.com axfr instructs dig to request a zone transfer for "victim.com" from the nameserver at 10.0.0.1. The @ symbol specifies the target server, overriding the system's default resolver.
Technical Details:
The AXFR query is sent over TCP (port 53), not UDP, due to the potentially large size of zone data, which exceeds UDP's typical 512-byte limit (pre-EDNS0).
Successful execution requires the nameserver to permit zone transfers from the querying IP, often restricted to trusted secondaries via Access Control Lists (ACLs) for security. If restricted, the server responds with a "REFUSED" error.
Security Implications: Zone transfers expose all DNS records (e.g., A, MX, NS), making them a reconnaissance goldmine for attackers if misconfigured. CNSP likely emphasizes securing DNS servers against unauthorized AXFR requests, using tools like dig to test vulnerabilities.
Why other options are incorrect:
A . dig @10.0.0.1 victim.com axrfr: "axrfr" is a typographical error. The correct query type is "axfr." Executing this would result in a syntax error or an unrecognized query type response from dig.
B . dig @10.0.0.1 victim.com afxr: "afxr" is another typo, not a valid DNS query type per RFC 1035. dig would fail to interpret this, likely outputting an error like "unknown query type." C . dig @10.0.0.1 victim.com arfxr: "arfxr" is also invalid, a jumbled version of "axfr." It holds no meaning in DNS protocol standards and would fail similarly.
Real-World Context: Penetration testers use dig ... axfr to identify misconfigured DNS servers. For example, dig @ns1.example.com example.com axfr might reveal subdomains or internal IPs if not locked down.

NEW QUESTION # 63
Which built-in Windows utility can be used to verify the validity of a Kerberos ticket?

A. Klist
B. Kerbtray
C. Kerberos Manager
D. Netsh

Answer: A

Explanation:
Kerberos is the default authentication protocol in Windows Active Directory environments, and tickets are used to prove identity. Verifying ticket validity involves checking their status, expiration, and attributes, which requires a built-in tool available in modern Windows systems.
Why A is correct: Klist is a command-line utility included in Windows (since Vista/2008) that lists cached Kerberos tickets and their details, such as validity period and renewal status. CNSP recognizes it as the standard tool for Kerberos ticket management in security audits.
Why other options are incorrect:
B: Kerbtray is a graphical tool from the Windows Resource Kit, not a built-in utility, and is outdated.
C: Netsh manages network configurations, not Kerberos tickets.
D: "Kerberos Manager" is not a recognized built-in Windows utility; it's a fictitious name.
