Question: Which Of The Following Is An Example Of Data Link Layer Vulnerability?

Which of the following is an example of application layer vulnerability?

Explanation: Very complex application security controls can be an example of application layer vulnerability.

Inadequate security controls, as well as logical bugs in programs, are some other examples of such type..

What type of addressing is used at the data link layer?

Physical addressingThe LLC sublayer deals with addressing and multiplexing. Physical addressing for network connections exists at the data link layer. The data link layer combines data bits into entities called frames. Network topologies like Ethernet exist at the data link layer.

What is the use of application layer?

An application layer is an abstraction layer that specifies the shared communications protocols and interface methods used by hosts in a communications network. The application layer abstraction is used in both of the standard models of computer networking: the Internet Protocol Suite (TCP/IP) and the OSI model.

What is Application Layer Security?

Application layer security refers to ways of protecting web applications at the application layer (layer 7 of the OSI model) from malicious attacks. Since the application layer is the closest layer to the end user, it provides hackers with the largest threat surface.

The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.

The physical and data link layers of the network protocol stack together define a machine’s network interface. … The physical layer describes the way data is actually transmitted on the network medium. The data link layer defines how these streams of bits are put together into manageable chunks of data.

Where is OSI model used?

IT professionals use OSI to model or trace how data is sent or received over a network. This model breaks down data transmission over a series of seven layers, each of which is responsible for performing specific tasks concerning sending and receiving data.

The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. … 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.

What is OSI layer with example?

The best known example of the Transport Layer is the Transmission Control Protocol (TCP), which is built on top of the Internet Protocol (IP), commonly known as TCP/IP. TCP and UDP port numbers work at Layer 4, while IP addresses work at Layer 3, the Network Layer.

The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. … It controls the transmission of data packets via remotely shared channels. It sends data over the network interface card.

The three main functions of the data link layer are to deal with transmission errors, regulate the flow of data, and provide a well-defined interface to the network layer.

What is TCP layer?

The TCP/IP model is not exactly similar to the OSI model. The TCP/IP model consists of five layers: the application layer, transport layer, network layer, data link layer and physical layer. … TCP/IP is a hierarchical protocol made up of interactive modules, and each of them provides specific functionality.

What are the 7 network layers?

What are the seven layers of the OSI model?The Physical Layer.The Data Link Layer. … The Network Layer. … The Transport Layer. … The Session Layer. … The Presentation Layer. … The Application Layer. This is the only layer that directly interacts with data from the user. …
