NEW QUESTION # 126
John is working as a network defender at a well-reputed multinational company. He wanted to implement security that can help him identify any future attacks that can be targeted toward his organization and take appropriate security measures and actions beforehand to defend against them. Which one of the following security defense techniques should be implement?
Answer: B
NEW QUESTION # 127
In which of the following attacks does an attacker successfully insert an intermediary software or program between two communicating hosts?
Answer: D
Explanation:
Man-in-the-middle attacks occur when an attacker successfully inserts an intermediary software or program between two communicating hosts. The intermediary software or program allows attackers to listen to and modify the communication packets passing between the two hosts. The software intercepts the communication packets and then sends the information to the receiving host. The receiving host responds to the software, presuming it to be the legitimate client.
Answer option B is incorrect. A Denial-of-Service (DoS) attack is mounted with the objective of causing a negative impact on the performance of a computer or network. It is also known as a network saturation attack or bandwidth consumption attack. Attackers perform DoS attacks by sending a large number of protocol packets to the network. The effects of a DoS attack are as follows:
Saturates network resources
Disrupts connections between two computers, thereby preventing communications between services Disrupts services to a specific computer Causes failure to access a Web site Results in an increase in the amount of spam A Denial-of-Service attack is very common on the Internet because it is much easier to accomplish. Most of the DoS attacks rely on the weaknesses in the TCP/IP protocol.
Answer option D is incorrect. A buffer-overflow attack is performed when a hacker fills a field, typically an address bar, with more characters than it can accommodate. The excess characters can be run as executable code, effectively giving the hacker control of the computer and overriding any security measures set. There are two main types of buffer overflow attacks:
stack-based buffer overflow attack:
Stack-based buffer overflow attack uses a memory object known as a stack. The hacker develops the code which reserves a specific amount of space for the stack. If the input of user is longer than the amount of space reserved for it within the stack, then the stack will overflow.
heap-based buffer overflow attack:
Heap-based overflow attack floods the memory space reserved for the programs.
Answer option A is incorrect. Session hijacking refers to the exploitation of a valid computer session to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a remote server. It has particular relevance to Web developers, as the HTTP cookies used to maintain a session on many Web sites can be easily stolen by an attacker using an intermediary computer or with access to the saved cookies on the victim's computer (see HTTP cookie theft).
TCP session hijacking is when a hacker takes over a TCP session between two machines. Since most authentication only occurs at the start of a TCP session, this allows the hacker to gain access to a machine.
NEW QUESTION # 128
Which of the following is a physical security device designed to entrap a person on purpose?
Answer: C
NEW QUESTION # 129
Which of the following is a Windows in-built feature that provides filesystem-level encryption in the OS (starting from Windows 2000), except the Home version of Windows?
Answer: A
Explanation:
The Encrypting File System (EFS) is a Windows built-in feature that provides filesystem-level encryption, introduced in version 3.0 of NTFS. It enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer. EFS is available in all versions of Windows from Windows 2000 onwards, except the Home versions. This feature allows users to encrypt files on a per-file, per-directory, or per-drive basis, and some EFS settings can be mandated via Group Policy in Windows domain environments.
NEW QUESTION # 130
James was inspecting ARP packets in his organization's network traffic with the help of Wireshark. He is checking the volume of traffic containing ARP requests as well as the source IP address from which they are originating. Which type of attack is James analyzing?
Answer: C
Explanation:
James is analyzing an ARP Poisoning attack. This type of attack occurs when an attacker sends falsified ARP (Address Resolution Protocol) messages over a local area network. This results in the linking of an attacker's MAC address with the IP address of a legitimate computer or server on the network. Once the attacker has inserted their MAC address into the ARP cache of other devices, they can intercept, modify, or stop data in transit, effectively performing a man-in-the-middle or denial of service attack.
References: The analysis of ARP packets to identify potential ARP Poisoning is a critical skill for network defenders, as outlined in the EC-Council's Certified Network Defender (CND) course. The course emphasizes understanding and identifying various network threats, including ARP-related attacks, which are fundamental to maintaining network security123.
