Which one of the following services is not a UDP-based protocol?
Protocols are defined by their transport layer usage (TCP or UDP), impacting their security and performance characteristics.
Why D is correct: SSH (Secure Shell) uses TCP (port 22) for reliable, connection-oriented communication, unlike the UDP-based options. CNSP contrasts TCP and UDP protocol security.
Why other options are incorrect:
A: SNMP uses UDP (ports 161, 162) for lightweight network management.
B: NTP uses UDP (port 123) for time synchronization.
C: IKE (IPsec key exchange) uses UDP (ports 500, 4500).
You are performing a security audit on a company's infrastructure and have discovered that the domain name system (DNS) server is vulnerable to a DNS cache poisoning attack. What is the primary security risk?
DNS cache poisoning, also known as DNS spoofing, involves an attacker injecting false DNS records into a resolver's cache, altering how domain names resolve.
Why A is correct: The primary risk is that an attacker can redirect users to malicious websites (e.g., phishing or malware sites) by poisoning the DNS cache with fake IP addresses. This can lead to credential theft, data exfiltration, or malware distribution. CNSP identifies this as the core threat of DNS cache poisoning, aligning with real-world attack vectors.
Why other option is incorrect:
B . Manipulate the cache of the web server or proxy server: This describes web cache poisoning, a different attack targeting HTTP caches, not DNS servers. DNS cache poisoning affects DNS resolution, not web or proxy server caches directly.
If you find the 111/TCP port open on a Unix system, what is the next logical step to take?
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.
Which SMB (Server Message Block) network protocol version introduced support for encrypting SMB traffic?
The SMB protocol, used for file and printer sharing, has evolved across versions, with significant security enhancements in later iterations.
Why C is correct: SMBv3, introduced with Windows 8 and Server 2012, added native support for encrypting SMB traffic. This feature uses AES-CCM encryption to protect data in transit, addressing vulnerabilities in earlier versions. CNSP notes SMBv3's encryption as a critical security improvement.
Why other options are incorrect:
A . SMBv1: Lacks encryption support and is considered insecure, often disabled due to vulnerabilities like WannaCry exploitation.
B . SMBv2: Introduces performance improvements but does not support encryption natively.
D . None of the above: Incorrect, as SMBv3 is the version that introduced encryption.
How many usable TCP/UDP ports are there?
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) port numbers are defined by a 16-bit field in their packet headers, as specified in RFC 793 (TCP) and RFC 768 (UDP). A 16-bit integer ranges from 0 to 65,535, yielding a total of 65,536 possible ports (2^16). However, port 0 is universally reserved across both protocols and is not considered 'usable' for standard network communication. According to the Internet Assigned Numbers Authority (IANA), port 0 is designated for special purposes, such as indicating an invalid or dynamic port assignment in some systems (e.g., when a client requests an ephemeral port). In practice, operating systems and applications avoid binding to port 0 for listening services, and it's often used in error conditions or as a placeholder in protocol implementations (e.g., socket programming).
Thus, the usable port range spans from 1 to 65,535, totaling 65,535 ports. These ports are categorized by IANA into:
Well-Known Ports (0--1023): Reserved for system services (e.g., HTTP on 80/TCP). Note that 0 is still reserved within this range.
Registered Ports (1024--49151): Assigned to user applications.
Dynamic/Ephemeral Ports (49152--65535): Used temporarily by clients.
From a security perspective, understanding the usable port count is critical for firewall configuration, port scanning (e.g., with Nmap), and detecting anomalies (e.g., services binding to unexpected ports). Misconfiguring a system to use port 0 could lead to protocol errors or expose vulnerabilities, though it's rare. The CNSP curriculum likely emphasizes this distinction to ensure practitioners can accurately scope network security assessments.
Why other options are incorrect:
A . 65536: This reflects the total number of possible ports (0--65535), but it includes the reserved port 0, which isn't usable for typical TCP/UDP communication. In security contexts, including port 0 in a count could lead to misconfigured rules or scanning errors.
C . 63535: This is an arbitrary number with no basis in the 16-bit port structure. It might stem from a typo or misunderstanding (e.g., subtracting 2000 from 65535 incorrectly), but it's invalid.
D . 65335: Similarly, this lacks grounding in protocol standards. It could be a miscalculation (e.g., subtracting 200 from 65535), but it doesn't align with TCP/UDP specifications.
Real-World Context: In penetration testing, tools like Nmap scan ports 1--65535 by default, excluding 0 unless explicitly specified (e.g., -p0-65535), reinforcing that 65,535 is the practical usable count.
