Which of the following is an intentional act of sending multiple copies of the identical content to the same recipient?

VPN technology is structured on the basis of tunneling. It requires the setting up and upholding of a logical network connection. The packets built in a particular VPN protocol design are put in a nutshell inside another base or carrier protocol. They are then transmitted between the VPN client and the server and deencapsulated finally on the receiving side. Which of the following statements best describes the function of voluntary tunneling?

A security strategy in which several protection layers are placed throughout an information system helps to prevent direct attacks against an information system and data because a break in one layer only leads the attacker to the next layer. What is this security strategy called?

Which of the following attack allows attackers to bypass client-ID security mechanisms and gain access privileges, and then inject malicious scripts into specific web pages?

The security of the network can be increased in a number of ways, for instance, by installing a special kind of web server and through packet filtering. What type of server is implemented as an intermediary server between a client and a server to act as a shield and protect and hide the computer from the outside network?

An algorithm which is a part of the U.S. government's long-term project to develop a set of standards for publicly available cryptography as authorized by the Computer Security Act of 1987 accepts a message of 264 bits in length and a 160-bit message output digest is produced to complicate text searching. Which of the following algorithms is a family of two similar hash functions, with different block sizes, and uses 32-bit words and 64-bit words?

Kelly is taking backups of the organization’s data. Currently, he is taking backups of only those files which are created or modified after the last backup. What type of backup is Kelly using?

WEP is a component of the IEEE 802.11 WLAN standards. Its primary purpose is to provide for the confidentiality of data on wireless networks at a level equivalent to that of the wired LANs. In a wireless LAN, the network can be accessed without physically connecting to the LAN. On what layer of the OSI model, WEP utilizes an encryption mechanism for minimizing unauthorized access on the WLAN?

A DoS attack is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have. At the data link layer, DoS attacks can be done easily. DoS attacks at the application and transport layers are primarily the same, but the interaction between the network, data-link, and physical layers which increase the risk of a DoS attack on a wireless network is different. An attacker can create a device that will saturate the 802.11 frequency bands with noise. If the attacker can create enough RF noise to reduce the signal-to-noise ratio to an unusable level, then the devices within the range of the noise will be effectively taken offline to block the communication. What type of DoS attack is being discussed here?

Timothy works as a network administrator in a multinational organization. He decides to implement a dedicated network for sharing storage resources. He uses a _______ as it separates the storage units from the servers and the user network.
