276. Frage
Network security is the specialist area, which consists of the provisions and policies adopted by the Network Administrator to prevent and monitor unauthorized access, misuse, modification, or denial of the computer network and network-accessible resources. For which of the following reasons is network security needed? Each correct answer represents a complete solution. Choose all that apply.
Antwort: A,B,C,D
Begründung:
Network security is needed for the following reasons: To protect private information on the Internet To protect information from unwanted editing, accidentally or intentionally by unauthorized users To protect information from loss and deliver it to its destination properly To prevent a user from sending a message to another user with the name of a third person
277. Frage
Which of the following tools is used to ping a given range of IP addresses and resolve the host name of the
remote system?
Antwort: D
278. Frage
Which of the following OSI layers establishes, manages, and terminates the connections between the local and remote applications?
Antwort: A
Begründung:
The session layer of the OSI/RM controls the dialogues (connections) between computers. It establishes, manages and terminates the connections between the local and remote application. It provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. The OSI model made this layer responsible for graceful close of sessions, which is a property of the Transmission Control Protocol, and also for session checkpointing and recovery, which is not usually used in the Internet Protocol Suite. The Session Layer is commonly implemented explicitly in application environments that use remote procedure calls. Answer option C is incorrect. The Application Layer of TCP/IP model refers to the higher-level protocols used by most applications for network communication. Examples of application layer protocols include the File Transfer Protocol (FTP) and the Simple Mail Transfer Protocol (SMTP). Data coded according to application layer protocols are then encapsulated into one or more transport layer protocols, which in turn use lower layer protocols to affect actual data transfer. Answer option A is incorrect. The Data Link Layer is Layer 2 of the seven-layer OSI model of computer networking. It corresponds to or is part of the link layer of the TCP/IP reference model. The Data Link Layer is the protocol layer which transfers data between adjacent network nodes in a wide area network or between nodes on the same local area network segment. The Data Link Layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the Physical Layer. Examples of data link protocols are Ethernet for local area networks (multi-node), the Point-to-Point Protocol (PPP), HDLC, and ADCCP for point-to-point (dual-node) connections. Answer option B is incorrect. The network layer controls the operation of subnet, deciding which physical path the data should take, based on network conditions, priority of service, and other factors. Routers work on the Network layer of the OSI stack.
279. Frage
The network administrator wants to strengthen physical security in the organization. Specifically, to implement a solution stopping people from entering certain restricted zones without proper credentials. Which of following physical security measures should the administrator use?
Antwort: A
Begründung:
A mantrap is a physical security mechanism designed to control access to a secure area through a small space with two sets of interlocking doors. It is an effective measure to prevent unauthorized access, as it allows only one person to pass through at a time after authentication, thereby stopping any attempt at `tailgating' or `piggybacking' where an unauthorized individual might try to follow an authorized person into a restricted zone.
280. Frage
USB ports enabled on a laptop is an example of____
Antwort: A
Begründung:
The term "attack surface" refers to the sum of all possible points where an unauthorized user can try to enter data to or extract data from an environment. The enabled USB ports on a laptop are considered a part of the physical attack surface because they allow for physical interaction with the device. This includes the potential for unauthorized devices to be connected, which could be used to compromise security, such as through the introduction of malware or the unauthorized copying of sensitive data.
References: This explanation aligns with the definitions provided in network security resources, which categorize attack surfaces based on the nature of the interaction-physical, network, or software12. The reference to the physical attack surface includes any physical means by which data can be compromised, which encompasses USB ports on a laptop1.
