The SecOps Group Certified Network Security Practitioner 認定 CNSP 試験問題 (Q47-Q52):
質問 # 47
What types of attacks are phishing, spear phishing, vishing, scareware, and watering hole?
- A. Ransomware
- B. Probes
- C. Social engineering
- D. Insider threats
正解:C
解説:
Social engineering exploits human psychology to manipulate individuals into divulging sensitive information, granting access, or performing actions that compromise security. Unlike technical exploits, it targets the "human factor," often bypassing technical defenses. The listed attacks fit this category:
Phishing: Mass, untargeted emails (e.g., fake bank alerts) trick users into entering credentials on spoofed sites. Uses tactics like urgency or trust (e.g., typosquatting domains).
Spear Phishing: Targeted phishing against specific individuals/organizations (e.g., CEO fraud), leveraging reconnaissance (e.g., LinkedIn data) for credibility.
Vishing (Voice Phishing): Phone-based attacks (e.g., fake tech support calls) extract info via verbal manipulation. Often spoofs caller ID.
Scareware: Fake alerts (e.g., "Your PC is infected!" pop-ups) scare users into installing malware or paying for bogus fixes. Exploits fear and urgency.
Watering Hole: Compromises trusted websites frequented by a target group (e.g., industry forums), infecting visitors via drive-by downloads. Relies on habitual trust.
Technical Details:
Delivery: Email (phishing), VoIP (vishing), web (watering hole/scareware).
Payloads: Credential theft, malware (e.g., trojans), or financial fraud.
Mitigation: User training, email filters (e.g., DMARC), endpoint protection.
Security Implications: Social engineering accounts for ~90% of breaches (e.g., Verizon DBIR 2023), as it exploits unpatchable human error. CNSP likely emphasizes awareness (e.g., phishing simulations) and layered defenses (e.g., MFA).
Why other options are incorrect:
A . Probes: Reconnaissance techniques (e.g., port scanning) to identify vulnerabilities, not manipulation-based like these attacks.
B . Insider threats: Malicious actions by authorized users (e.g., data theft by employees), not external human-targeting tactics.
D . Ransomware: A malware type (e.g., WannaCry) that encrypts data for ransom, not a manipulation method-though phishing often delivers it.
Real-World Context: The 2016 DNC hack used spear phishing to steal credentials, showing social engineering's potency.
質問 # 48
Which of the following represents a valid Windows Registry key?
- A. HKEY_LOCAL_USER
- B. HKEY_INTERNAL_CONFIG
- C. HKEY_ROOT_CLASSES
- D. HKEY_LOCAL_MACHINE
正解:D
解説:
The Windows Registry is a hierarchical database storing system and application settings, organized into predefined root keys (hives). Only specific names are valid as top-level keys.
Why A is correct: HKEY_LOCAL_MACHINE (HKLM) is a standard root key containing hardware and system-wide configuration data. CNSP references it for security settings analysis (e.g., auditing policies).
Why other options are incorrect:
B: HKEY_INTERNAL_CONFIG is not a valid key; no such hive exists.
C: HKEY_ROOT_CLASSES is a misspelling; the correct key is HKEY_CLASSES_ROOT (HKCR).
D: HKEY_LOCAL_USER is incorrect; the valid key is HKEY_CURRENT_USER (HKCU).
質問 # 49
Which of the following attacks are associated with an ICMP protocol?
- A. ICMP flooding
- B. All of the following
- C. Ping of death
- D. Smurf attack
正解:B
解説:
ICMP (Internet Control Message Protocol), per RFC 792, handles diagnostics (e.g., ping) and errors in IP networks. It's exploitable in:
A . Ping of Death:
Method: Sends oversized ICMP Echo Request packets (>65,535 bytes) via fragmentation. Reassembly overflows buffers, crashing older systems (e.g., Windows 95).
Fix: Modern OSes cap packet size (e.g., ping -s 65500).
B . Smurf Attack:
Method: Spoofs ICMP Echo Requests to a network's broadcast address (e.g., 192.168.255.255). All hosts reply, flooding the victim.
Amplification: 100 hosts = 100x traffic.
C . ICMP Flooding:
Method: Overwhelms a target with ICMP Echo Requests (e.g., ping -f), consuming bandwidth/CPU.
Variant: BlackNurse attack targets firewalls.
Technical Details:
ICMP Type 8 (Echo Request), Type 0 (Echo Reply) are key.
Mitigation: Rate-limit ICMP, disable broadcasts (e.g., no ip directed-broadcast).
Security Implications: ICMP attacks are DoS vectors. CNSP likely teaches filtering (e.g., iptables -p icmp -j DROP) balanced with diagnostics need.
Why other options are incorrect:
A, B, C individually: All are ICMP-based; D is comprehensive.
Real-World Context: Smurf attacks peaked in the 1990s; modern routers block them by default.
質問 # 50
If you find the 111/TCP port open on a Unix system, what is the next logical step to take?
- A. None of the above.
- B. Telnet to the port to look for a banner.
- C. Telnet to the port, send "GET / HTTP/1.0" and gather information from the response.
- D. Run "rpcinfo -p <hostname>" to enumerate the RPC services.
正解:D
解説:
Port 111/TCP is the default port for the RPC (Remote Procedure Call) portmapper service on Unix systems, which registers and manages RPC services.
Why A is correct: Running rpcinfo -p <hostname> queries the portmapper to list all registered RPC services, their programs, versions, and associated ports. This is a logical next step during a security audit or penetration test to identify potential vulnerabilities (e.g., NFS or NIS services). CNSP recommends this command for RPC enumeration.
Why other options are incorrect:
B . Telnet to the port to look for a banner: Telnet might connect, but RPC services don't typically provide a human-readable banner, making this less effective than rpcinfo.
C . Telnet to the port, send "GET / HTTP/1.0" and gather information from the response: Port 111 is not an HTTP service, so an HTTP request is irrelevant and will likely fail.
D . None of the above: Incorrect, as A is a valid and recommended step.
質問 # 51
How many octets are there in an IPv6 address?
- A. 0
- B. 1
- C. 2
- D. 3
正解:B
解説:
An IPv6 address, defined in RFC 4291, is a 128-bit address designed to replace IPv4's 32-bit scheme, vastly expanding address space (2
