The SecOps Group Certified Network Security Practitioner Sample Questions (Q56-Q61):

NEW QUESTION # 56
Which of the following attacks are associated with an ICMP protocol?

A. All of the following
B. Ping of death
C. ICMP flooding
D. Smurf attack

Answer: A

Explanation:
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.

NEW QUESTION # 57
Which of the following is an example of a SUID program?

A. /bin/ls
B. /usr/bin/passwd
C. /usr/bin/curl
D. None of the above

Answer: B

Explanation:
In Linux/Unix, the SUID (Set User ID) bit allows a program to execute with the owner's permissions, typically root, rather than the caller's. It's denoted by an s in the user execute field (e.g., -rwsr-xr-x). Common SUID programs perform privileged tasks requiring temporary elevation.
Analysis:
C . /usr/bin/passwd:
Purpose: Updates user passwords in /etc/shadow (root-owned, 0600 perms).
Permissions: Typically -rwsr-xr-x, owned by root. The SUID bit lets non-root users modify shadow securely.
Command: ls -l /usr/bin/passwd confirms SUID (s in user execute).
A . /bin/ls:
Purpose: Lists directory contents, no privileged access needed.
Permissions: -rwxr-xr-x (no SUID). Runs as the calling user.
B . /usr/bin/curl:
Purpose: Transfers data over HTTP/FTP, no root privileges required by default.
Permissions: -rwxr-xr-x (no SUID).
Technical Details:
SUID Bit: Set via chmod u+s <file> or chmod 4755.
Security: SUID binaries are audited (e.g., find / -perm -u=s) due to escalation risks if writable or poorly coded (e.g., buffer overflows).
Security Implications: CNSP likely highlights SUID as an attack vector (e.g., CVE-1996-0095 exploited passwd flaws). Hardening removes unnecessary SUID bits.
Why other options are incorrect:
A, B: Lack SUID; no privileged operations.
D: Incorrect, as /usr/bin/passwd is a SUID example.
Real-World Context: SUID on /bin/su or /usr/bin/sudo similarly enables privilege escalation, often targeted in exploits.

NEW QUESTION # 58
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 # 59
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.

NEW QUESTION # 60
Which one of the following services is not a UDP-based protocol?

A. IKE
B. NTP
C. SNMP
D. SSH

Answer: D

Explanation:
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).
