The SecOps Group Certified Network Security Practitioner Sample Questions (Q32-Q37):

NEW QUESTION # 32
Which SMB (Server Message Block) network protocol versions are vulnerable to the EternalBlue (MS17-010) Windows exploit?

  • A. SMBv2 only
  • B. SMBv3 only
  • C. Both SMBv1 and SMBv2
  • D. SMBv1 only

Answer: D

Explanation:
EternalBlue (MS17-010) is an exploit targeting a buffer overflow in Microsoft's SMB (Server Message Block) implementation, leaked by the Shadow Brokers in 2017. SMB enables file/printer sharing:
SMBv1 (1980s): Legacy, used in Windows NT/XP.
SMBv2 (2006, Vista): Enhanced performance/security.
SMBv3 (2012, Windows 8): Adds encryption, multichannel.
Vulnerability:
EternalBlue exploits a flaw in SMBv1's SRVNET driver (srv.sys), allowing remote code execution via crafted packets. Microsoft patched it in March 2017 (MS17-010).
Affected OS: Windows XP to Server 2016 (pre-patch), if SMBv1 enabled.
Proof: WannaCry/NotPetya used it, targeting port 445/TCP.
SMBv1 Only: The bug resides in SMBv1's packet handling (e.g., TRANS2 requests). SMBv2/v3 rewrote this code, immune to the specific overflow.
Microsoft: Post-patch, SMBv1 is disabled by default (Windows 10 1709+).
Security Implications: CNSP likely stresses disabling SMBv1 (e.g., via Group Policy) and patching, as EternalBlue remains a threat in legacy environments.
Why other options are incorrect:
B, C: SMBv2/v3 aren't vulnerable; the flaw is SMBv1-specific.
D: SMBv2 isn't affected, only SMBv1.
Real-World Context: WannaCry's 2017 rampage hit unpatched SMBv1 systems (e.g., NHS), costing billions.


NEW QUESTION # 33
What is the response from a closed TCP port which is not behind a firewall?

  • A. ICMP message showing Port Unreachable
  • B. A RST and an ACK packet
  • C. A FIN and an ACK packet
  • D. A SYN and an ACK packet

Answer: B

Explanation:
TCP uses a structured handshake, and its response to a connection attempt on a closed port follows a specific protocol when unobstructed by a firewall.
Why C is correct: A closed TCP port responds with a RST (Reset) and ACK (Acknowledgment) packet to terminate the connection attempt immediately. CNSP highlights this as a key scanning indicator.
Why other options are incorrect:
A: ICMP Port Unreachable is for UDP, not TCP.
B: FIN/ACK is for closing active connections, not rejecting new ones.
D: SYN/ACK indicates an open port during the TCP handshake.


NEW QUESTION # 34
Which of the following services do not encrypt its traffic by default?

  • A. All of these
  • B. SSH
  • C. FTPS
  • D. DNS

Answer: D

Explanation:
Encryption ensures confidentiality and integrity of network traffic. Analyzing defaults:
A . DNS (Domain Name System):
Default: Unencrypted (UDP/TCP 53), per RFC 1035. Queries/responses (e.g., "google.com → 142.250.190.14") are plaintext.
Modern Options: DNS over HTTPS (DoH, TCP 443) or DNS over TLS (DoT, TCP 853) encrypt, but aren't default in most systems (e.g., pre-2020 Windows).
B . SSH (Secure Shell):
Default: Encrypted (TCP 22), per RFC 4251. Uses asymmetric (e.g., RSA) and symmetric (e.g., AES) copyright for all sessions.
C . FTPS (FTP Secure):
Default: Encrypted (TCP 21 control, dynamic data ports). Extends FTP with SSL/TLS (e.g., RFC 4217), securing file transfers.
Technical Details:
DNS: Plaintext exposes queries to eavesdropping (e.g., ISP snooping) or spoofing (e.g., cache poisoning).
SSH/FTPS: Encryption is baked into their standards; disabling it requires explicit misconfiguration.
Security Implications: Unencrypted DNS risks privacy and integrity (e.g., Kaminsky attack). CNSP likely pushes DoH/DoT adoption.
Why other options are incorrect:
B, C: Encrypt by default.
D: False, as only DNS lacks default encryption.
Real-World Context: The 2013 Snowden leaks exposed DNS monitoring; DoH uptake (e.g., Cloudflare 1.1.1.1) counters this.


NEW QUESTION # 35
Which of the following protocols is not vulnerable to address spoofing attacks if implemented correctly?

  • A. TCP
  • B. ARP
  • C. IP
  • D. UDP

Answer: A

Explanation:
Address spoofing fakes a source address (e.g., IP, MAC) to impersonate or amplify attacks. Analyzing protocol resilience:
C . TCP (Transmission Control Protocol):
Mechanism: Three-way handshake (SYN, SYN-ACK, ACK) verifies both endpoints.
Client SYN (Seq=X), Server SYN-ACK (Seq=Y, Ack=X+1), Client ACK (Ack=Y+1).
Spoofing Resistance: Spoofer must predict the server's sequence number (randomized in modern stacks) and receive SYN-ACK, impractical without session hijacking or MITM.
Correct Implementation: RFC 793-compliant, with anti-spoofing (e.g., Linux tcp_syncookies).
A . UDP:
Connectionless (RFC 768), no handshake. Spoofed packets (e.g., source IP 1.2.3.4) are accepted if port is open, enabling reflection attacks (e.g., DNS amplification).
B . ARP (Address Resolution Protocol):
No authentication (RFC 826). Spoofed ARP replies (e.g., fake MAC for gateway IP) poison caches, enabling MITM (e.g., arpspoof).
D . IP:
No inherent validation at Layer 3 (RFC 791). Spoofed source IPs pass unless filtered (e.g., ingress filtering, RFC 2827).
Security Implications: TCP's handshake makes spoofing harder, though not impossible (e.g., blind spoofing with sequence prediction, mitigated since BSD 4.4). CNSP likely contrasts this with UDP/IP's vulnerabilities in DDoS contexts.
Why other options are incorrect:
A, B, D: Lack handshake or authentication, inherently spoofable.
Real-World Context: TCP spoofing was viable pre-1990s (e.g., Mitnick attack); modern randomization thwarts it.


NEW QUESTION # 36
Which one of the following is not an online attack?

  • A. Brute force attack
  • B. Phishing attack
  • C. Rainbow table attack
  • D. Password spraying attack

Answer: C

Explanation:
Online attacks require real-time interaction with a target system (e.g., a login interface), whereas offline attacks occur without direct system interaction, typically after obtaining data like password hashes. A rainbow table attack is an offline method that uses precomputed tables of hash values to reverse-engineer passwords from stolen hash databases, distinguishing it from the other options, which are online.
Why B is correct: Rainbow table attacks are performed offline after an attacker has already acquired a hash (e.g., from a compromised database). The attacker matches the hash against precomputed tables to find the plaintext password, requiring no interaction with the target system during the attack. CNSP classifies this as an offline password recovery technique.
Why other options are incorrect:
A: Brute force attacks involve repeatedly submitting password guesses to a live system (e.g., via SSH or a web login), making it an online attack.
C: Password spraying attacks test a few common passwords across many accounts on a live system, also an online attack aimed at avoiding lockouts.
D: Phishing attacks trick users into submitting credentials through fake interfaces (e.g., emails or websites), requiring real-time interaction and thus classified as online.
