NEW QUESTION # 198
Which of the following Wireshark filters allows an administrator to detect SYN/FIN DDoS attempt on the network?
- A. tcp.flags==0X029
- B. TCP.flags==0x300
- C. tcp.flags==0x003
- D. tcp.dstport==7
Answer: A
Explanation:
The correct Wireshark filter to detect a SYN/FIN DDoS attempt is tcp.flags==0X029. This filter is designed to capture packets where both the SYN and FIN flags are set, which is an unusual combination and indicative of a SYN/FIN attack. In a typical three-way TCP handshake, the SYN and FIN flags are not set in the same TCP segment. A SYN flag is used to initiate a connection, and a FIN flag is used to politely close a connection. Therefore, seeing both flags set in the same packet suggests a possible SYN/FIN DDoS attack.

NEW QUESTION # 202
Docker provides Platforms-a-Service (PaaS) through __________ and deliver*; containerized software packages
- A. Network level virtualization
- B. OS level visualization
- C. Storage-level virtualization
- D. Server-level visualization
Answer: B
Explanation:
Docker provides Platform-as-a-Service (PaaS) through OS-level virtualization. This form of virtualization allows for the deployment of software in packages called containers. Containers are isolated from each other and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels. OS-level virtualization is lightweight compared to other forms of virtualization because it does not require a hypervisor to create virtual machines. Instead, the Docker Engine enables the containers to run directly within the host machine's operating system but with separate namespaces, which is why it's considered OS-level.

An attacker has access to password hashes of a Windows 7 computer. Which of the following attacks can the attacker use to reveal the passwords?
- A. Dictionary attacks
- B. Brute force
- C. XSS
- D. Rainbow table
Answer: D
Explanation:
In the context of password hashes on a Windows 7 computer, a Rainbow Table attack is a feasible method an attacker might use to reveal passwords. This type of attack utilizes precomputed tables known as rainbow tables that contain hash values for every possible combination of characters. An attacker with access to password hashes can use these tables to look up the corresponding plaintext passwords. The effectiveness of rainbow tables stems from their ability to reverse cryptographic hash functions, which are used to store passwords securely. Since Windows 7 uses NTLM hashes, which are known to be vulnerable to rainbow table attacks, this method is particularly relevant12.
References: The explanation draws upon the known vulnerabilities of NTLM hash functions in Windows 7 and the general principles of rainbow table attacks as discussed in security literature12.

John has implemented________in the network to restrict the limit of public IP addresses in his organization and to enhance the firewall filtering technique.
- A. Proxies
- B. DMZ
- C. NAT
- D. VPN
Answer: C
Explanation:
Network Address Translation (NAT) is a network function that translates private IP addresses into a public IP address. This technique restricts the number of public IP addresses required by an organization, as multiple devices on a private network can share a single public IP address. NAT also enhances firewall filtering techniques by hiding the internal IP addresses from the external network, which adds a layer of security by making it more difficult for attackers to target specific devices within the organization's network. It is a common practice in network security to use NAT in conjunction with firewalls to manage the traffic entering and leaving the network, ensuring that only authorized access is permitted.
References: The information provided aligns with the Certified Network Defender (CND) program's focus on network defense fundamentals, including the application of network security controls like NAT12. Additionally, NAT's role in conserving IP addresses and providing security by hiding internal network addresses is well-documented and is part of the network security best practices345.
NEW QUESTION # 210
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==12) || (icmp.type==15 || (icmp.type==17)
- C. (icmp.type==14) || (icmp.type==15 || (icmp.type==17)
- D. (icmp.type==9 && ((!(icmp.code==9))
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.
References: The use of Wireshark filters to identify specific types of ICMP traffic is a common practice in network analysis. The Certified Network Defender (CND) course material covers various network monitoring tools and techniques, including the analysis of ICMP traffic for security purposes1. Additionally, resources like Wireshark documentation and network security forums provide practical examples of filters used to detect ICMP fingerprinting attempts23.

Identify the firewall technology that monitors the TCP handshake between the packets to determine whether a requested session is legitimate.
- A. Packet Filtering Firewall
- B. Circuit Level Gateway
- C. Network Address Translation
- D. Stateful Multilayer Inspection
Answer: D
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.
References: The role of Stateful Multilayer Inspection in monitoring TCP handshakes is covered in the Certified Network Defender (CND) course materials, which detail the functionalities of different firewall technologies and their application in network security123.
