質問 # 19
Rosa is working as a network defender at Linda Systems. Recently, the company migrated from Windows to MacOS. Rosa wants to view the security related logs of her system, where con she find these logs?
正解：C
解説：
In MacOS, security-related logs are typically stored in the /private/var/log directory. This location is used to store various system logs, including authentication attempts and other security events. The secure.log file within this directory is particularly relevant for tracking security incidents, as it records authentication attempts and other security-related events. It's important for network defenders like Rosa to be familiar with these log locations to monitor and respond to potential security issues on the systems they manage12.
References: The information provided here is consistent with standard MacOS logging practices and the EC-Council's Certified Network Defender (CND) curriculum, which includes understanding the security mechanisms of different operating systems and how to locate and interpret system logs12. For more detailed information, please refer to the official CND study materials and documents provided by the EC-Council.
質問 # 20
Consider a scenario consisting of a tree network. The root Node N is connected to two man nodes N1 and N2.
N1 is connected to N11 and N12. N2 is connected to N21 and N22. What will happen if any one of the main nodes fail?
正解：B
解説：
In a tree network, each node is connected in a hierarchical manner, with the root node at the top. If a main node (such as N1 or N2) fails, all the child nodes connected to it (N11, N12 for N1 and N21, N22 for N2) will be affected because the tree structure relies on the connectivity of the parent node to its children. The failure of a main node will disrupt the transmission path from the root to the child nodes, leading to a loss of connectivity for those child nodes. This is consistent with the principles of network resilience and fault tolerance as outlined in the EC-Council's Certified Network Defender (CND) program, which emphasizes the importance of each node in maintaining the network's overall integrity.
References: The explanation is based on the standard network topologies and fault tolerance principles covered in the EC-Council's Certified Network Defender (CND) curriculum.
質問 # 21
Which of the following is a Unix and Windows tool capable of intercepting traffic on a network segment and
capturing username and password?
正解：B
解説：
Ettercap is a Unix and Windows tool for computer network protocol analysis and security auditing. It is capable
of intercepting traffic on a network segment, capturing passwords, and conducting active eavesdropping
against a number of common protocols. It is a free open source software. Ettercap supports active and passive
dissection of many protocols (including ciphered ones) and provides many features for network and host
analysis.
Answer option C is incorrect. BackTrack is a Linux distribution distributed as a Live CD, which is used for
penetration testing. It allows users to include customizable scripts, additional tools and configurable kernels in
personalized distributions. It contains various tools, such as Metasploit integration, RFMON injection capable
wireless drivers, kismet, autoscan-network (network discovering and managing application), nmap, ettercap,
wireshark (formerly known as Ethereal).
Answer option A is incorrect. AirSnort is a Linux-based WLAN WEP cracking tool that recovers encryption
keys. AirSnort operates by passively monitoring transmissions. It uses Ciphertext Only Attack and captures
approximately 5 to 10 million packets to decrypt the WEP keys. Answer option D is incorrect. Aircrack is the
fastest WEP/WPA cracking tool used for 802.11a/b/g WEP and WPA cracking.
質問 # 22
Oliver is a Linux security administrator at an MNC. An employee named Alice has resigned from his organization and Oliver wants to disable this user in Ubuntu. Which of the following commands can be used to accomplish this?
正解：D
解説：
In Linux, to disable a user account, the usermod command is used with the -L option. This option locks the user's password, effectively disabling the account by preventing the user from logging in. The command usermod -L alice will lock the user 'alice' by adding an exclamation mark (!) in front of the encrypted password in the /etc/shadow file, which is the standard method for disabling an account in Linux.
質問 # 23
Carla, a senior network defender at a multinational finance firm, observes irregular communication patterns in the internal network that do not match any known threat signatures.
Despite no alerts from signature-based systems, a few security components have issued warnings based on the deviation from expected network behavior. Carla suspects these components are responsible for highlighting new and unknown intrusion attempts. Which intrusion detection mechanism is responsible for generating alerts based on behavioral deviations from normal traffic?
正解：A
解説：
Anomaly-based detection identifies potential threats by comparing current network activity against a baseline of normal behavior. When traffic patterns deviate significantly from this baseline, the system generates alerts even if the activity does not match known attack signatures. This approach is effective for detecting previously unknown or zero-day attacks that signature-based systems may miss.
