Which filter to locate unusual ICMP request an Analyst can use in order to detect a ICMP probes from the attacker to a target OS looking for the response to perform ICMP fingerprinting?
- A. (icmp.type==8 && ((!(icmp.code==8))
- B. (icmp.type==9 && ((!(icmp.code==9))
- C. (icmp.type==14) || (icmp.type==15 || (icmp.type==17)
- D. (icmp.type==12) || (icmp.type==15 || (icmp.type==17)
Answer: A
Explanation:
In the context of network security, ICMP fingerprinting is a technique used to determine the operating system of a target machine by analyzing its responses to ICMP requests. The correct filter to detect unusual ICMP requests that could be indicative of ICMP probes from an attacker is option C. This filter looks for ICMP echo requests (type 8) that do not have a corresponding echo reply (code 0). Since the code for an echo request is 0, the filter (!(icmp.code==8)) is used to exclude other ICMP messages with different codes.

Which of the following protocols permits users to enter a user-friendly computer name into the Windows browser and to map network drives and view shared folders?
- A. VoIP
- B. RADIUS
- C. NetBEUI
- D. ARP
Answer: C
Explanation:
NetBIOS Extended User Interface (NetBEUI) is a Microsoft proprietary protocol. NetBEUI is usually used in single LANs comprising one to two hundred clients. It is a non-routable protocol. NetBEUI was developed by IBM for its LAN Manager product and has been adopted by Microsoft for its Windows NT, LAN Manager, and Windows for Workgroups products. It permits users to enter a user-friendly computer name into the Windows browser and to map network drives and view shared folders.
Answer option C is incorrect. Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet- switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, Voice over Broadband (VoBB), broadband telephony, and broadband phone.
VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs that encode speech, allowing transmission over an IP network as digital audio via an audio stream.
Answer option A is incorrect. RADIUS is a client/server protocol that runs in the application layer, using UDP as transport. The Remote Access Server, the Virtual Private Network server, the Network switch with port-based authentication, and the Network Access Server are all gateways that control access to the network, and all have a RADIUS client component that communicates with the RADIUS server. The RADIUS server is usually a background process running on a UNIX or Windows NT machine.
RADIUS serves three functions:
To authenticate users or devices before granting them access to a network; To authorize those users or devices for certain network services; To account for usage of those services.
Answer option D is incorrect. Address Resolution Protocol (ARP) is a computer networking protocol used to determine a network host's Link Layer or hardware address when only its Internet Layer (IP) or Network Layer address is known. This function is critical in local area networking as well as for routing internetworking traffic across gateways (routers) based on IP addresses when the next-hop router must be determined.

You are monitoring your network traffic with the Wireshark utility and noticed that your network is experiencing a large amount of traffic from a certain region. You suspect a DoS incident on the network. What will be your first reaction as a first responder?
- A. Disable Virus Protection
- B. Communicate the incident
- C. Make an initial assessment
- D. Avoid Fear, Uncertainty and Doubt
Answer: C
Explanation:
As a first responder to a suspected DoS incident, the initial reaction should be to make an initial assessment.
This involves quickly evaluating the situation to understand the scope and impact of the incident. An initial assessment helps in determining whether the unusual traffic is indeed a DoS attack or a false positive. It also aids in deciding the next steps, such as whether to escalate the incident, what resources are required, and how to communicate the issue to relevant stakeholders.
References: The approach aligns with best practices for incident response, which emphasize the importance of an initial assessment to understand the nature and extent of a security incident before proceeding with further actions123.
NEW QUESTION # 188
Sean has built a site-to-site VPN architecture between the head office and the branch office of his company.
When users in the branch office and head office try to communicate with each other, the traffic is encapsulated. As the traffic passes though the gateway, it is encapsulated again. The header and payload both are encapsulated. This second encapsulation occurs only in the __________implementation of a VPN.
- A. Transport Mode
- B. Full Mesh Mode
- C. Tunnel Mode
- D. Point-to-Point Mode
Answer: C
Explanation:
In the context of VPNs, when both the header and payload of traffic are encapsulated, it indicates the use of Tunnel Mode. This mode is typically employed in site-to-site VPNs where the entire IP packet is wrapped with a new IP header. Tunnel Mode is designed to secure traffic between different networks over the internet, making it suitable for connecting multiple sites of an organization. Unlike Transport Mode, which only encrypts the payload and leaves the original IP header intact, Tunnel Mode encrypts the entire IP packet and adds a new header, which allows for the secure passage of the traffic through untrusted networks.
References: The explanation provided aligns with standard VPN implementations and the principles outlined in network security documents and study guides related to Certified Network Defender (CND) objectives.

Which of the following tools are NOT used for logging network activities in the Linux operating system? Each correct answer represents a complete solution. Choose all that apply.
- A. Timbersee
- B. PsLoggedOn
- C. Swatch
- D. PsGetSid
Answer: B,D
Explanation:
PsLoggedOn and PsGetSid are not logging tools. They are command-line utilities used in the Windows operating system. PsLoggedOn is an applet that displays both the local and remote logged on users. If an attacker specifies a user name instead of a computer, PsLoggedOn searches the computers in the network and tells whether the user is currently logged on or not. The command syntax for PsLoggedOn is as follows: psloggedon [- ] [-l] [-x] [\\computername | username] PsGetSid is a tool that is used to query SIDs remotely. Using PsGetSid, the attacker can access the SIDs of user accounts and translate an SID into the user name. The command syntax for PsGetSid is as follows: psgetsid [\\computer[,computer[,...] | @file] [-u username [-p password]]] [account|SID] Answer options C and D are incorrect. Timbersee and Swatch are tools used for logging network activities in the Linux operating system.
NEW QUESTION # 197
Identify the firewall technology that monitors the TCP handshake between the packets to determine whether a requested session is legitimate.
- A. Circuit Level Gateway
- B. Network Address Translation
- C. Stateful Multilayer Inspection
- D. Packet Filtering Firewall
Answer: C
Explanation:
Stateful Multilayer Inspection firewalls monitor the state of active connections and determine which network packets to allow through the firewall. They are designed to inspect the TCP handshake, which is the initial connection setup process between two hosts in a network. By monitoring this handshake, the firewall can determine whether a requested session is legitimate. This technology allows the firewall to not only filter packets based on predefined rules but also to ensure that the packets are part of an established and approved connection.
