...manageable pieces, packaging and addressing them so they will arrive at their proper destination and then reassembling the pieces into the original signal or stream. This paper will observe the part the Transport layer plays in application data encapsulating for use by the Network layer; how it allows simultaneous communication of multiple applications on a single host device while ensuring reliable data delivery to the right application correcting errors if required. The Transport layer is layer 4 in the Open Systems Interconnection (OSI) Model and layer 2 in the Transmission Control Protocol/Internet Protocol (TCP/IP) Model. The Transport layer is needed to track individual conversations, segment, manage and reassemble data packets, identify sending and receiving applications, perform flow control between end users, enable error recovery and initiate and terminate sessions. Any one host may have several applications that are using the network to communicate at one time. The Transport layer’s responsibility is to keep track of and maintain the communication streams that are taking place with each of these applications. Each application creates a stream of data that it uses to communicate with another application using the network. Most of these streams...

...Nalapatla 3884252 What is a Port Number A port number is a way to identify a specific process to which an internet or other network message is to be forwarded when it arrives at a server. For the transmission control protocol and the user Datagram protocol, a port number is a 16 bit integer that is put the header appended to a message unit. This port number is passed logically between the client and the server transport layers and physically between the transport layer and the Internet Protocol layer and it will forward it on to the other layers. For an example, a request from a client to a server on the internet may request a file to transfer from the host File Transport Protocol (FTP) server. In order to pass that request which is passed by us to the FTP in the remote server, the Transmission Control Protocol (TCP) identifies the port number which is of 16 bit length, then that port will forward the request to the FTP Server. FTP and the FTP Port Number The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to the other host over a TCP – based network, for an example Internet. FTP is a Client – server architecture and uses a separate control and the data connections between the client and the server. The model of the FTP is shown below. Fig 1: File Transport Protocol Model Executing an FTP port connection through a client is two – stage process requiring the use of two different ports. Once the user enter the...

...Unit 3 Assignment 1 Choosing Port Scanning Software NT2670, James Fairchild 1. What is Port Scanning? Is a software application designed to probe a server or host for open ports. This is often used by administrators to verify security policies of their networks and by attackers to identify running services on a host with the view to compromise it. 2. What is the goal of Port Scanning? The results of a scan on a port is usually generalized into one of three categories, Open or accepted: The host sent a reply indicating that a service is listening on the port. Closed or denied or not listening: the host sent a reply indicating that connections will be denied to a port. Filtered, dropped or blocked no reply from the host. Open ports present two vulnerabilities of which administrators must be wary, Security and stability concerns associated with the programs responsible for delivering the service- open ports. Security and stability concerns associated with the operating system that is running on the host. Open or closed ports. 3. Would you prefer an open source or proprietary port scanning software? Depending on who you ask? Many people in business prefer to use proprietary software instead of open source software, due to the misconception that proprietary software is better supported than open source. After several years of supporting both open source and proprietary software it becomes clearly evident that just because you pay for proprietary software does not mean...
